NexGen Why Is My AC Spitting Ice

If your air conditioner is spitting out ice, the evaporator or condenser coils are probably frozen. Allowing your AC to continue running can cause serious damage, or at the very least accelerate wear. There are a few answers to the question, “Why is my AC spitting ice?” We will list a few below to help you troubleshoot the issue and know whether you need an HVAC technician’s help.

The Outside Temperature Has Dropped Below 62℉

An air conditioner is designed to keep your home cooler than the outside air temperature. It’s unlikely you’d want it to be colder than 62℉ indoors. If the AC is running full blast, this can cause the temperature around the evaporator coil to fall below freezing. Any condensation or moisture present will freeze on contact. When the outside temperature falls, run the AC in fan mode or turn the system off and use a ceiling fan or open a window.

Refrigerant Is Low and/or Leaking

If your AC is spitting ice and you hear a hissing sound, there’s likely a refrigerant leak. Only a trained technician can fix the problem. The coolant in your AC runs through a closed system. It should never be low. If it is, there will be serious temperature regulation problems in the system and components can easily freeze.

The AC Filter Is Dirty

A filter helps keep the air clean, but your air conditioner will run without it. However, when the filter gets dirty or clogged, it’s a different story. A clogged filter reduces airflow. Without enough air passing through them, the coils get colder causing ice to form. To avoid filter issues, replace it every three to six months.

The Evaporator Coil Is Dirty

When the evaporator coil is coated in dirt, it won’t allow for effective heat transfer. Warm air may never reach the coils. As a result, they get colder, and frost forms on the surface. Some of this ice can break loose in the airflow and get flung out of the AC vents.

Clogged Condensate Drain

The AC can spit water if the drain is clogged with dirt, mold, or algae. Moisture regularly condensates in an AC system; this is what the drip pan is for. It collects condensate so it can be evacuated via a drain. If the drain isn’t functioning, water can leak from the unit and performance can be affected. The coils may eventually freeze if the issue isn’t fixed.

The Fan Is Not Working Properly

Insufficient airflow can cause the coil to get cold and freeze, resulting in ice spitting from the AC. This may be due to a faulty fan motor, which can occur due to mechanical or electrical issues. The fan can become loose or break as well. Repairing or replacing an AC fan requires technical expertise.

How Do I Thaw Out My Air Conditioner?

You can thaw out the unit by running it in fan mode. The ice should start to break down soon after. You might also want to leave the system off, although the process may take five or more hours to complete. During that time, install a new filter just to be on the safe side.

NexGen How Long Should an AC Run on a 100 Degree Day

In Southern California, 100+ degree days are becoming more common. Extreme temperatures can put quite a strain on your AC. In general, air conditioners run in cycles of about 15 to 20 minutes. Longer than that can indicate a problem, but how long should an AC run on a 100-degree day?

Your AC will work harder to cool your home when outdoor temperatures are higher than normal. The compressor will run more frequently to reach and maintain the desired indoor temperature. It’s quite possible the air conditioner will run all the time if the temperature hits 100 and soars even higher. 

Is My AC Working Properly?

Even though your AC will likely run often on a hot day, there are signs to look for that might indicate a problem, such as the AC running continuously, yet your home isn’t staying cool or getting cool at all. This can mean:

The thermostat is the first place you should look. If it was accidentally switched to heating mode, then your home won’t get cool. Switching it to the proper mode should resolve the issue. Also, use the “auto” setting so the system will run until it reaches the desired temperature. For the most efficient performance, set the thermostat 20 degrees lower than the temperature outside. On a 100 day, set it to 78 to 80 to manage utility costs.

If there’s a lack of air flow, the filter may need to be changed or AC vents cleaned. But it may also mean your air conditioner needs professional repair. If an evaporator or condenser coil is dirty, this can block the transfer of heat, so air coming from the vents may be less cool. Low refrigerant levels can cause your AC to run all day. You may also hear a bubbling or hissing noise or see refrigerant leaking, which can be a dangerous situation. 

If your AC isn’t working properly, it’s important to call an HVAC contractor quickly to resolve the problem.

Don’t Run Out and Get a Bigger AC

Average daily high temperatures seem to be increasing and there are more hot days per year than ever before. But an AC must still be properly sized. Oversizing a unit will cause your house to cool too quickly. It won’t run long enough to remove humidity, making it clammier and more conducive to condensation and mold. The system will also use more energy leading to higher electricity bills.

Tips for Running Your AC on a 100 Degree Day

In addition to keeping the thermostat at a reasonable setting, here are some ways you can keep your home cool on the hottest days:

The Top 5 Most Expensive HVAC & Plumbing Repairs

The Top 5 Most Expensive HVAC Plumbing Repairs

When you add up the expenses of major home repairs, you can understand why proper care and maintenance are so important. Major components and the labor needed to replace them can cost hundreds to thousands of dollars. Here, we’ll look at some of the most expensive HVAC and plumbing repair jobs you might encounter:

  1. 1. Bathroom Water Damage

Leaking, standing, or running water will damage your home more quickly than you might think. It can soak through flooring materials, walls, and framing. Leaking pipes and fixtures are a common culprit. But a lack of caulking is a serious problem. Periodically check/replace the caulking or grout between tiles or water can easily percolate through and cause the underlying wood to rot. Mold and mildew may be growing below the surface before you know the extent of the damage.

If just everything around your shower space is severely damaged, replacing it all can cost $10,000 to $15,000.

  1. 2. Slab Leak Repair

Detecting a slab foundation leak alone can cost several hundred dollars. Thicker slabs may require more time not just to find a leak, but to fix it, especially the deeper the affected pipe is. Repairing a slab usually involves removing the overlying flooring, so the type of flooring material to take out and replace is a cost factor. Vapor barriers, rebar, and other materials as well as portions of the foundation may also need to be removed.

Expect to spend up to $4,000, but many variables can jack up the price, including the amount of digging and how much pipe-work is needed.

  1. 3. AC Compressor Failure

Of all HVAC repairs, compressor failure is the one homeowners dread the most. Fortunately, compressors are very durable and reliable. But dirty coils, low refrigerant, overheating, and electrical problems can strain the compressor and cause it to fail. Replacing it is time-consuming and requires a great deal of expertise.

The average cost to replace an AC compressor is $1,800, but parts and labor costs can be as high as $2,380.

  1. 4. HVAC Condenser Damage

The condenser, or outdoor unit, is designed to release heat. Unless it is protected, an exposed condenser unit can be damaged by debris. Electrical problems, refrigerant leaks, and various other problems can occur as well. There are many parts inside the condenser so diagnosing an issue can take some time. Fixing the unit can also take time depending on the location and scope of the problem.

Replacing the condenser coil can cost up to $2,800, depending on the size of the unit. Line and radiator blockages can be just as expensive to fix. Smaller repairs are generally in the hundreds of dollars. These are all far less than replacing the condenser, which can be about $4,000.

  1. 5. Refrigerant Leak

Refrigerant lines run throughout your HVAC system. If you notice signs of a leak, a technician must take time to find where it is. Leaks can be detected electronically, via dye, using nitrogen, by looking for air bubbles or employing ultrasonic equipment. The cost of fixing the leak depends on accessibility, how much damage there is, and the age of the system.

On average, you may spend up to $1,500 on this repair, but fixing a refrigerant line can cost as much as $2,000. If the evaporator coil, condenser coil, or compressor needs replacement, it will increase the cost significantly.

Air Conditioning Installation: A Step-by-Step Process

Air Conditioning Installation A Step by Step Process

Whether it’s been 15 or 20 years since installing your air conditioner, the time may have come to replace it. That’s a pretty good length of time. Even well-maintained AC’s eventually reach the end of their life. At NexGen, we’ve provided air conditioning installation in countless homes and businesses. In this step-by-step guide, we’ll provide a look into our process that ensures your investment pays off.

Step 1: In-Home Consultation

Assuming your current AC isn’t fixable, we’ll send a licensed contractor to evaluate what you have and what type of air conditioner is best for your home. Newer air conditioners tend to be larger to accommodate larger, more efficient coils. Therefore, the location of your existing AC may not be sufficient. A different area may need to be considered.

Another factor is the unit’s cooling capacity. You don’t want an AC that’s too small or too big or it won’t run efficiently. This can reduce comfort and strain the system so it costs more to run and repair more frequently.

Step 2: Removing the Old System

To remove an old AC system, several complex tasks are required. First, the refrigerant must be removed; this involves specialized equipment and a trained technician. By law, only EPA-certified personnel can remove, handle, and dispose of refrigerant, which can be toxic. Coolant cannot be vented into open air; a sophisticated machine pumps it into a recovery tank.

It's also necessary to protect areas of your home. Air conditioning equipment is heavy and there may be debris to clean up. During this process, installers will cover floors and furniture for protection and also inspect for sealing issues in your home and air duct leaks. These can impact the performance of a new system so must be fixed before installation begins.

Step 3: Preparation

The pad for the old outdoor unit must be replaced to accommodate the new air conditioner. Newer units are larger and wider. The ground may also need to be leveled before the technician can set the new pad. A gravel base should be used to level the area or build it up, while a vibration-absorbing composite pad is preferred over poured concrete that can crack and shift.

The area must be stable, as moving or lifting the air conditioner can cause severe damage. Rigid internal components cannot withstand much motion, while some are pressurized as well. Once the system is connected, it must remain in place, so the pad won’t need repair during the unit’s lifetime.

Before the indoor evaporator coil is replaced, the metal plenum is disconnected. Refrigerant lines, which consist of two copper pipes, may be reused (and first flushed, cleaned, and pressure-tested). However, a technician will likely recommend installing a new line.

Refrigerant lines are often strapped to the bottom of floor joists. Straps must be removed before taking out the line set. Line sets may also be located within ceilings or walls or buried underground. To make things easier, a new line set may be run while the old one remains.

Step 4: Outdoor Unit Installation

The AC condenser is placed on the composite pad and inspected for potential damage. Next, the line set is fitted to the new unit’s service valve, which isolates the refrigerant and the outdoor condenser from the indoor coil. This avoids having to replace refrigerant if a repair is needed. The copper line set and valves are brazed, or welded, together to ensure a leak-proof connection. Then the filter dryer is installed in the condenser, preferably next to the expansion valve, to absorb moisture and provide filtration.

Step 5: Wiring Installation

The new service disconnect box is mounted to the side of your house and wired to the electric panel. An installer may provide a fused box that supports overcurrent protection, or a non-fused box if the existing breaker matches the AC manufacturer’s listed maximum overcurrent protection. High- and low-voltage wiring will then be reconnected; line, or wiring from the panel, and load, a power conduit to the AC, is connected. All electrical installations are installed in accordance with the National Electrical Code (NEC).

Step 6: Indoor Evaporator Coil Installation

A cased evaporator coil is preferably installed. It has an insulated cabinet with panels that allow access to the coil and sits on top of the furnace. The coil is then connected and sealed to the existing sheet metal plenum. Uncased coils require additional preparation and installation work before connecting them. Rails must be installed to ensure the coil sits above the furnace heat exchanger at the proper distance, or else the drain pan can melt. But if the opening isn’t big enough or too much air can flow through, the coil will freeze.

Step7: Refrigerant Line Installation

Refrigerant line sets include two copper lines; the suction line is larger and insulated, while the liquid line is smaller. Rolled into a coil, these are available in lengths of 15 to 50 feet. Lines are set near beams and ductwork, if possible, and secured every 4 to 6 feet with plastic or copper strapping. Once hangers are installed to secure the lines, the suction line is usually installed first and connected to the AC, and run to the indoor evaporator coil. The liquid line is then run along the same path and secured.

Installers will take care not to bend, kink, or otherwise damage the lines. During the process, the installer will push unrolled sections of tubing through a 2” to 2.5” hole in the outside wall near the AC. Just enough line is then pushed out to reach the service valve. When refrigerant is added, special care is taken not to expose it to the air and contaminate it. 

Heat protection is then applied and dry nitrogen is used to protect the interior of copper tubing from oxidation during welding. Dry nitrogen also allows the installer to perform a preliminary leak test, collect moisture, and purge some contaminants. A vacuum process is then used to remove oxygen, nitrogen, and moisture that can affect the operation and damage the system.

Step 8: Condensate Drain Line Installation

The primary condensate line runs from the evaporator coil to a floor drain or condensate pump. A PVC pipe allows moisture to flow from your home when the AC is running. Condensate tubing or piping is secured and glued when installed to protect against flooding, and a safety overflow switch is connected to the evaporator coil’s secondary port. It’s also wired to the furnace control, so the system shuts off when tripped.

Step 9: Thermostat Installation

During air conditioner installation, a new thermostat is usually provided. If you keep your existing thermostat, the installer will check the connection between it and the new system. They can also install a separate thermostat if you want a smart system, for example. Your AC installer should also demonstrate how to use your new thermostat.

Step 10: System Testing

The technician will run the air conditioner for up to 20 minutes. During initial startup, refrigerant will start flowing and the system will start to condition the air. It will feel warm at first. But you’ll soon start to feel the difference. All the while, the unit’s sequence of operation, thermostat function, and a range of parameters will be tested.

What to Do in an HVAC Emergency

What to Do HVAC Emergency

We tend to think that, when we need air conditioning or heating, our HVAC systems will respond to every command. And that may be the case for quite a long time. That is until your system suddenly quits. While many emergencies can be avoided, sometimes a mechanical system as complex as an HVAC unit can fail. Here, we’ll look at how to deal with an HVAC emergency and ways to reduce the odds of experiencing one.

Assess the Situation

Are you experiencing a true emergency? That depends on the reason why your AC isn’t working. Sometimes a simple problem can cause it not to work, such as the wrong setting or a tripped circuit breaker. Be proactive if the solution isn’t simple. If there’s an elderly and/or chronically ill family member or occupant in your home, extreme temperatures can be very dangerous.

In any case, if there isn’t an immediate solution, it’s best to call an HVAC professional. Air conditioner problems tend to start with one component. When a single issue isn’t dealt with promptly, the stress it can cause on other parts is often enough to trigger a cascade of failures. Then you may need to fix multiple issues, if not end up replacing the entire system. That is a much more expensive scenario.

It's therefore wise to call a contractor once you realize there’s an HVAC emergency.

Reach Out to an Experienced HVAC Repair Company

It’s imperative to have the right person check your HVAC system. Far too often, homeowners call the cheapest company they can find, only to be visited by an inexperienced service contractor. The risks include them breaking an important part, skipping key steps, and installing inferior components. On top of the problem you had, your entire system can malfunction. Just one small error can cost you a great deal of money; so, don’t dwell on investing more upfront for high-quality, skilled help.

When Am I Most Likely to Experience an HVAC Emergency?

HVAC emergencies are unpredictable. They happen suddenly and almost always at the most inconvenient time, like during a famous Los Angeles heat wave. However, there are factors that can increase the risk of experiencing one, including:

The Different Types of Air Ductwork Explained

The Different Types of Air Ductwork Explained 1

Cooling or heating air is just one function of your HVAC system. For the system to serve its purpose, there must be a way for conditioned air to reach each room. Dedicated channels, or air ducts, distribute air throughout a house or commercial building. 

Air ducts can be rigid or flexible but there are a few types to choose from depending on your needs. An HVAC professional can help decide on the right type of air ductwork and material.

Your options for HVAC ductwork include the following:

Sheet Metal Ducts

Aluminum or galvanized steel air ducts are extremely durable and the most commonly installed. Aluminum is often preferred as it’s lightweight, strong, and easy to install. Galvanized steel ducts are coated with zinc to prevent rust and are often lined with fiberglass for insulation. Like most rigid ducts, both types can be cylindrical or rectangular in shape.

Sheet metal is nonporous, which resists mold and bacteria and can improve air quality. One drawback, however, is that when sections are joined, the duct can leak. It’s also known to trap dust and particles; although easy to clean, ductwork should be periodically cleaned by a professional.

Fiberglass Ducts

Fiberglass air ductwork has thermal insulation properties and is protected against heat loss and condensation. The fiberglass lining may be installed inside or outside the duct. Interior surfaces absorb sound. This allows an HVAC system to operate more quietly, which is typically preferred in commercial or office buildings.

However, fiberglass ducts require more cleaning and maintenance because they’re more prone to mold and bacterial growth. Cleaning requires being careful because damaging the lining can release fiberglass particles into the air supply, creating potential health hazards. Deterioration of the lining can release fibers as well.

Fiberboard Ducts

Inorganic glass fibers are compressed into board, so fiberglass particles are sealed and cannot shed into the air. An air and moisture barrier is created by a foil covering. Fiberboard ducts are therefore well-insulated and don’t require any additional insulation materials. They’re also the most affordable to install.

Fiberboard ducts have textured interior surfaces where dust and debris can collect, and mold and bacteria can grow especially in humid areas. Rough surfaces also create friction. This disruption in air flow can reduce HVAC efficiency.

Flexible Ducts

Flexible ducts are among the most affordable to install and can be used in tight or difficult spaces. They can bend around structures, providing an alternative to traditional rigid ducts. Usually made of steel wire helixes within a durable plastic layer, flexible ducts also feature insulation surrounding the round tubes to maintain airflow and temperature.

However, sharp bends can create kinks and other areas of restricted airflow. This will reduce efficiency. Complicating matters are the internal ridges that can disrupt air that passes through. One must also be careful to avoid punctures and sags during installation. Nonetheless, flexible ducts offer superior resistance to rust and mold.

Should I Repair or Replace My R22 Refrigerant Air Conditioner?

Should I Repair or Replace My R22 Refrigerant Air Conditioner 1 1It has been illegal to produce or import R22 refrigerant in the U.S. since January 1, 2020. The Environmental Protection Agency’s (EPA) ban on this ozone-depleting substance began a phase-out of the product. Additionally, the manufacture of R22 AC or heat pump systems was banned to make way for chlorine-free R410A refrigerant.

The ban affects:

The new R410A refrigerant is non-ozone depleting, environmentally friendly, and non-flammable. It also doesn’t contain butane, isopentane, isobutane, or other hydrocarbons. 

Can an R22 Air Conditioner Still Be Repaired?

For now, you can still use your R22 air conditioner. However, fixing it can be problematic and expensive. Servicing it may require using R22 refrigerant stockpiles or reclaimed refrigerant. Like any AC system, old or new, these crucial pieces of HVAC equipment use refrigerant to absorb or release heat as it flows through a series of coils. Refrigerant transforms between liquid and gas states and undergoes pressure changes to exert a change in air temperature.

Repairing an old air conditioner can be expensive because R22 supplies are dwindling. You may find refrigerant for equipment made before 2010, but it’s only going to get even more expensive as time goes on. A leak can and should be repaired rather than simply topping off the system. But if you need a substantial amount of R22, it may cost more to repair the system than put money down on a new AC.

About Retrofitting an Existing System

Another alternative to replacement is retrofitting your current R22 air conditioner to work with the new refrigerant. Also known as a “drop-in” replacement, this requires significant modifications to equipment. Otherwise, it won’t run because R410A refrigerant requires different pressure levels than R22. If doing a retrofit, check the warranty to see if it’ll cover damages in case of a problem. There’s also the risk of voiding the system warranty and safety certification, which is another reason to consider a replacement.

Is It Time to Replace My R22 Refrigerant AC?

Squeezing another year or two out of your old system may ultimately cost more than replacing it sooner. The situation can get quite urgent if your old AC suddenly quits. Shopping around for a new heating and cooling system gives you time to plan and install it on your schedule. Meanwhile, you can evaluate product reviews, costs, and energy efficiency as well as the latest features.

Your AC dealer can also help you evaluate the best options for your home. Many offer financing options to help afford your new system. You can benefit from greater reliability and lower electric bills along with low monthly payments. Purchasing a new heating and cooling system does not have to be a financial strain.

Reasons to replace your R22 AC now include:

You can also avoid a sudden failure on a hot summer day. Nexgen can be reached 24/7 to promptly address any issues you’re having. To help you know when to call for service, here are signs your air conditioner needs repair.

Nexgen Air Conditioning Heat X Signs Your Air Conditioner Needs Repair

1. Only Warm Air Is Blowing

An air conditioner is designed to provide cool air. When the AC is turned on, there should never be warm air blowing from the vents. If so, check that the thermostat is in cooling mode. Otherwise, warm air blowing can mean something is blocking airflow or there’s damage to the compressor.

2. The AC Is Making Odd Noises

If the unit is making sounds you’ve never heard, it’s time to call for repairs. There may be a blockage or a mechanical problem. Worrisome sounds include grinding, scraping, squealing, or gurgling. Ignoring the noise can lead to more serious and expensive damage.

3. It’s Turning On and Off Too Fast

Air conditioners typically run in cycles. They stay on until the set temperature is reached, and turn off until the temperature needs to be readjusted. Your AC will run more frequently on hot days. If it’s constantly turning on and off, the system may need to be repaired or replaced.

4. Vents Are Blowing Little or No Air

Even if you’re getting cold air, weak air flow is a sign of a duct clog or leak. It can also mean the compressor is failing. If there’s a ductwork issue or a motor is breaking down, the problem can be fixed. In some cases, the issue is so serious replacing the unit is the only solution.

5. You Can’t Get the Thermostat to Work

The thermostat is what controls your air conditioner. It measures temperature continuously to signal the AC to generate the right amount of cold air. Signs of a thermostat problem include the system not turning on at all, running for short amounts of time, or not providing the right temperature.

6. The AC Gives Off Bad Odors

There are also smelly signs your air conditioner needs repair. If there’s a musty odor, mold may be growing inside the AC unit or your ductwork. A burning odor can mean a wire or electrical component has burnt out. Ductwork cleaning, a tune-up, or installation of UV lamps in the system can eliminate AC odors.

7. Your Electric Bill Is Going Up

Your utility bill should remain fairly consistent. If you’re not using your AC more, but are spending more on electricity, there may be a repair issue such as a duct leak, faulty thermostat switch, clog, or other mechanical problem causing it to work harder.

8. The Unit Is Leaking

Refrigerant is constantly circulating throughout the system. Central air conditioners are also designed to drain condensate. If you see coolant pooling up, this can be a dangerous situation, while leaking water can cause serious property and structural damage.

9. Your Home Is More Humid

Even on humid summer days, your AC should keep indoor humidity levels in check. Schedule service if your home starts to feel stickier. If the humidity is above 50%, your home can become quite stuffy while mold can grow more easily. Watch for low-humidity and dryness as well.

10. Circuit Breakers Keep Tripping

If the breaker for your AC keeps tripping, there might be a serious electrical issue. An undiagnosed electrical problem can lead to equipment overheating or wires sparking. A home fire can result if the problem isn’t diagnosed and fixed.

Contact Nexgen for AC Repair

Are there signs your air conditioner needs repair? If so, Nexgen is ready to assist and can provide any repair necessary, starting with a free estimate. Maintenance and tune-up specials are available as well. Call 833-729-9735 to request a visit.

How do Air Purifiers Work

While an HVAC system offers some air filtration, it doesn’t filter out every particle of dust, pollen, or pet dander. Mold spores, smoke, odors, and other pollutants and potential toxins may exist in your indoor air, where they can be many times more concentrated than outdoors. An air purifier can remove these and improve comfort, help alleviate allergies, and reduce the risk of respiratory and other illnesses. In this article, we will answer the question, “How do air purifiers work?” to show you their potential benefits.

Function of an Air Purifier

An air purifier is an appliance that sucks in air via a fan and re-circulates it in a cleaner form. It can have one or multiple filters. These filters can be made of paper, fiberglass, or mesh. Some filters must be replaced as they fill up, while others are reusable and washable (however, they require substantial maintenance, but are effective at removing larger particles).

Filtration is an important aspect of air purifiers, but a purifier is much more than a filter. Some models act as air sanitizers as well. For example, air particles can be neutralized when ultraviolet light (UV) filters are integrated into the unit. UV light can destroy bacteria, mold, and other biological impurities. Without a special filter or sanitizing system, an air purifier will struggle to trap particles much smaller than 5 microns in size (high-efficiency filters can remove particles as small as 2.5 microns).1

*While coronavirus (COVID-19) particles measure about 0.1 microns, they’re usually bound to water droplets, aerosols, and other larger particles, so can be removed by air purifiers.

Air Purifier Limitations

A standard air filter struggles to remove volatile organic compounds (VOCs), radon, and other gases. Off gassing from household cleaning products, paints, and adhesives isn’t captured by most air purifiers either. That’s unless a High Efficiency Particulate Air (HEPA) filter is used. It’s made of fine fiberglass threads and is pleated and sealed in a frame made of plastic or metal. 

HEPA filters capture particles of various sizes, including VOCs, ozone, carbon monoxide, nitrogen dioxide, and sulfur dioxide when used in combination with UV light and air scrubbers.

But an air purifier won’t remove or neutralize particles stuck to walls (and other hard surfaces) or sitting on carpeting, furniture, bedding, and other soft surfaces.

When asking, “How do air purifiers work?” and deciding on the best one for your home, it’s also important to consider the following:

Types of Air Purifiers Nexgen Offers

Nexgen offers three different types of air purifiers. These include filter-based systems with electrically charged flat filters to capture large particles, extended media filters that remove dust and debris, and ultraviolet filters. In addition, we offer duct-based air purification systems designed to filter impurities from air as it passes through air ducts. Lastly, our stand-alone systems install in a closet or attic and are connected to your HVAC system via air intakes. Our licensed technicians can perform any installation for you, while your budget and air quality needs are addressed as part of our X protects standard.

Do I Need an AC Tune Up?

Do I Need an AC Tune Up

When we think of life’s necessities, an AC tune up doesn’t necessarily come to mind. Your air conditioner may run fine for a while whether someone looks at it or not. But a tune up has many benefits especially given the demand on your HVAC system throughout the year. Annual tune ups are fine for new systems; if you have an older air conditioner, consider having it checked in the spring and fall to ensure it’s in working order.

Reasons to Schedule an AC Tune Up

At Nexgen, we offer comprehensive maintenance programs that cover all the essentials. Our technicians are trained to properly inspect, service, and repair all types of air conditioning systems. We also know tune ups are important because of:

Increased Efficiency

As the weather warms up, you’ll be using your AC every day. This can exert a lot of strain if you haven’t used it for several months. Performing minor adjustments and addressing small issues will mean the system won’t work as hard. It may run less to achieve the same cool temperature, cutting down energy costs.

Lower Repair Costs

Many AC problems start small but get progressively worse. You might not notice the signs. However, an AC technician can find minor problems and fix them on the spot, so they won’t turn into larger problems that require expensive repairs. Roughly 95% of HVAC system breakdowns are preventable with regular maintenance and tune-ups.

Improved Comfort

A poorly maintained air conditioner may provide little or no cool air. Air distribution can be affected as well. With an AC tune up, the system will better regulate the temperature of your home, so your family stays comfortable.


Many HVAC warranties require regular maintenance to continue covering your AC system. If you skip professional maintenance, this can void the manufacturer’s warranty. The warranty provider may deny your repair claim and you’ll end up having to pay the full price of repairs or replace the system.

Air Quality Improvements

When tuning up the system, a technician will change the air filter, clean out components, and vacuum out ductwork. This reduces the amount of dust and allergens in the air. You’ll feel better and your HVAC system will run smoother.

Increased Operating Life

When you need big AC repairs, chances are something is causing components to wear out. If you’ve had one major repair, there are likely other issues brewing. Tune ups will keep the system running smoothly, which has proven to translate to a longer equipment lifespan.
