What Are the Latest California HVAC Regulations?

NexGen What Are the Benefits of Hydro Jetting Services

New California HVAC regulations are targeting refrigerant use and efficiency. This is not the first wave of changes in the industry. In 2013, Title 24 efficiency standards were set by the California Energy Commission; in 2016 the California Air Resources Board (CARB) was authorized to oversee the reduction of hydrofluorocarbon (HFC) emissions. Even more sweeping regulatory changes will take effect in 2023.

The U.S. Department of Energy has strictly regulated minimum efficiency levels for HVAC equipment since 1992. All air conditioning systems are measured using the seasonal energy efficiency ratio (SEER). Meanwhile, the heating seasonal performance factor (HSPF) is used for heat pumps and annual fuel utilization efficiency (AFUE) is used for furnaces. 

New Restrictions on Refrigerant

California passed legislation in 2018 that banned high global warming potential (GWP) HFCs, mirroring previous federal bans. California HVAC regulations announced in 2022 require:

Nationwide Guidelines Also Apply

The Department of Energy (DOE) has made changes that will impact the entire nation. In the southwestern region, which includes California, the minimum standard SEER rating for cooling systems will be increased to 15 SEER (for split units using less than 45,000 BTU) and 14.5 SEER (for units that use more than 45,000 BTU). New EER/EER2 requirements will also go into effect. In all regions, furnaces must have at least an 81% AFUE rating and air-source heat pumps must have a minimum heating efficiency of 8.8 HSPF.

According to Angi, the increased efficiency requirements can mean paying $350 to $1,500 more for a new air conditioner, heat pump, or packaged system.2 But higher efficiency can mean saving on heating/cooling bills each month. After all, heating and cooling account for 55% of the energy used in homes, based on numbers by the Office of Energy Efficiency and Renewable Energy.

The 2019 Building Energy Efficiency Standards

These changes included requirements for fan efficiency in forced air systems; for gas furnace air-handling units, fans must operate at 0.45 watts/cubic feet per minute (CFM) or less. For non-gas air-handling units, it is 0.58 watts/CFM. Meanwhile, small duct, high-velocity forced-air systems must have fans running at 0.62 watts/CFM or less (with an airflow requirement of 250 CFM /ton or greater).

Porous inner core flex ducts are required as well. The exception is if there’s a nonporous layer or air barrier between the duct’s inner layer and outer vapor barrier. Mandatory air filtration requirements for systems with 10 feet or more of duct were set as well, with filtration being required on supply and balanced mechanical ventilation systems.

Title 24 Compliance Still Applies

The Energy Commission’s 2013 Title 24 rules still apply. These are minimum efficiency standards intended to reduce energy consumption throughout the state and include requirements such as:

*If no ducts are replaced, there must be 15% or less leakage; if ductwork replacement is performed, leakage must not exceed 6%).

How Are Your HVAC and Plumbing Systems Connected?

NexGen How Are Your HVAC and Plumbing Systems Connected

Air conditioning (HVAC), and plumbing (which involves water supply/drainage lines and connected fixtures), are two separate systems. Most people don’t realize there’s any connection between them. However, HVAC and plumbing do interact, meaning the performance of one can affect the other.

Your Central AC System Has a Drainage Line

The drainage line for your HVAC system is the most common interaction point between it and your plumbing. It collects condensate from humidity (via the condensate pan under the indoor air handler). In some systems, the condensate drainage line delivers water directly to the sewer line. But usually, condensation drains via a line through an exterior wall and to the ground. The line may also be plumbed into an upstairs sink or another part of your plumbing system.

The following issues can arise due to HVAC/plumbing drainage issues:

A condensate drain can also become clogged. This problem can be identified when you don’t see the drain dripping when the AC is on. If the condensate line and a different part of your plumbing system are both clogged, a backup can occur. For example, if the HVAC condensate drain is tied to a sink, that sink may start draining slowly.

While the condensate drain can be cleaned by pouring a half-cup of vinegar into it, don’t attempt this too often. If the drain continues to clog up, have an HVAC technician look at it. Another issue is when there’s drainage and your air conditioner is not running.

Inadequate Heating Can Impact Your Plumbing

A compressor problem, low refrigerant, or poor maintenance (leading to dirty coils, clogged filters, etc.) can affect HVAC performance. Your heating system plays a role in keeping your plumbing warm as it does the interior of rooms. If it gets cold enough in your home, pipes could potentially freeze during the winter (especially if they’re installed within exterior walls). 

However, a more common issue is when the pipes in your AC system freeze. Since plumbing does not provide ventilation, it’s not going to help HVAC components warm up. If it’s too cold, pipes will continue to freeze and potentially crack and fail.

Often made of PVC tubing, condensation lines are prone to the same issues as water supply lines. They can be affected by cracks, broken joints, and ruptures. The effect is more subtle since the contents of an HVAC condensate line aren’t under pressure. Water exits a damaged line slowly and signs of an issue may develop incrementally over time.

HVAC and Plumbing Systems Both Need Maintenance and Professional Care

Different licensing and certifications are required to service either an HVAC or plumbing system. Air conditioning and heating systems need maintenance at least once or twice a year. Their mechanical nature means they’re highly prone to wear. But plumbing is always in high demand as well, and the presence of water means corrosion, clogs, or limescale can develop. A plumbing or HVAC failure can be costly to resolve. And, both are critically important to the function, comfort, and safety of your home.

Should I Avoid the Cheapest AC Installation?

NexGen Should I Avoid the Cheapest AC Installation

It can cost $10,000 or more to install a central air conditioning system in an average home. For most of us, saving money is a priority. But going for the cheapest AC installation can actually cost you more in the long run. In doing so, you risk:

Purchasing Low-Quality Equipment

Some brands are just more expensive than others, but cheap installation often sacrifices quality. The less you spend on an air conditioner, the less reliable and efficient it may be. You also might not get the features and options you need. You may pay higher electric bills and for repairs sooner than you would with a higher-end system. There’s also a risk that too small an AC will be installed, which will struggle to keep your home cool.

Poor Installation Service

HVAC companies that charge significant labor rates are generally committed to getting the job done right. A poor AC installation can mean the unit won’t keep up with your cooling needs, temperatures may vary from room to room, and your home may be too humid. Improperly installed air conditioners also cannot run as efficiently, so you end up paying higher utility bills. Aside from finding a reputable contractor, you want to make sure discounts or savings don’t equate to shortcuts.

Vague Service Proposals

A contractor’s proposal should itemize everything the service includes. Get every quote in writing and after the contractor inspects your home. A lowball price over the phone means nothing, as they won’t fully understand your needs or even do a load calculation first. The company should generously match a competitor’s price, but first, compare previous proposals you received. Allowing them to perform AC installation can mean dealing with discomfort, wasted energy, and poor air quality for years.

Incompatible Equipment

Replacing only the indoor or the outdoor unit can mean spending a lot more later. You won’t see efficiency benefits by combining a more modern unit with an older one. If the components are incompatible, the results can include reduced performance and comfort and strain that leads to major damage. Your best bet is to replace all HVAC components at once to ensure fewer problems and pay for only one installation visit.

Inexperienced Contractors

An AC contractor that charges cheap rates may not have the proper skills or licensing. It’s not cheap to obtain a state license, so a reputable installer must cover some of these costs. Additional training is needed to obtain North American Technician Excellence (NATE) certification and become a factory-authorized dealer. All these require a high level of expertise. It’s also important a contractor is insured; cheap service is an indicator they may not be.

If the quoted price is too good to be true, it probably is. There’s often a reason an HVAC contractor would charge such a low price, such as a history of bad reviews and poor installation service.

Is It Ever Okay to Save on AC Installation?

You can achieve savings and preserve quality by taking advantage of seasonal discounts, manufacturer’s rebates, and tax credits. When you get quotes from different contractors, compare what’s included in each to find the most value. Also, schedule AC installation for the spring and fall, when there’s less demand off-season. Generally, paying a fair price often means having a system that meets your needs and is affordable to operate.

So, the answer is, you should avoid the cheapest AC installation. There are safe ways to reduce the initial cost, but you can find opportunities to save later. These include changing your AC filters often, maintaining a constant temperature, and scheduling regular preventative maintenance when the manufacturer and contractor recommend it.

Ultimate Outdoor Air Conditioning Buying Guide

Air Conditioner Buying Guide

The outdoor air conditioner unit is an important part of your HVAC system. Containing the condenser coil, compressor, and fan, an outdoor unit releases heat absorbed from indoor air. But how do you choose an outdoor unit? It generally should match the brand and type of indoor air handler unit you have. In this buying guide, we’ll cover a few important considerations in selecting an outdoor air conditioner.

Types of Outdoor Air Conditioner Units

For a central air conditioning system, you’ll probably have one of two types of units. These are:

Choosing an Air Conditioner: Considerations

It’s unwise and impractical to choose just any air conditioner. For it to meet your needs and function properly, you need to think about:

Cost of Outdoor Air Conditioners

A central air conditioning system can cost from $3,000 to $7,000 to install. It’s usually not only the outdoor unit you need to install or replace. You need to factor in the cost of indoor air handlers, furnaces, ducts, and more as well as labor. A larger, more complex system can cost $20,000 or more.

Warranty

Make sure you fully understand the terms of the manufacturer’s warranty and what is covered. Some warranties provide different coverage for the unit and certain parts. Others may only cover labor for certain types of work. Neglecting to maintain the AC or having a non-authorized individual service it can void the warranty, so it’s important to understand all the terms and conditions.

Why Is My AC Spitting Ice?

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.

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

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

  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. Repair 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.2

  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 $2,380.3

  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 $4,000.4

  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 $2,000.5 If the evaporator coil, condenser coil, or compressor need 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.

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.

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:
