Any plumber will tell you a water leak can occur anywhere, even deep within your walls, above a ceiling, or under the floor. A gas leak releases toxic gas into the air. This is an extremely dangerous situation that risks your health and safety. That’s why you need a professional leak detection service to determine the exact source and nature of the leak so a plumber can fix it—fast.
Natural gas is readily available and affordable. This fossil fuel is found in the environment and is used for many things. Large companies carefully maintain gas and oil pipelines, but the containment of natural gas in your home can be a different story. It comes in through local gas lines and is used by furnaces, water heaters, stoves, fireplaces, and other fixtures.
A lack of maintenance, damage, or a repair issue with any one of these appliances can put your family in danger. Natural gas, propane, and butane are commonly used in homes. Normally, they are safe, but when something goes wrong, you may face issues such as:
High levels of gas can trigger a range of symptoms if inhaled. These can include:
In severe cases, a person exposed to natural gas can lose coordination and eventually become unconscious. Death can occur due to suffocation.
In addition, gas leaks, aside from wasting energy, are harmful to the environment. They can kill vegetation. In the case of methane, a leak can contribute to greenhouse gas emissions. Issues related to natural gas leaks, however, can be mitigated with early detection.
It’s crucial to find the leak or you may face extremely high repair expenses. Only a professional has the tools and equipment to quickly find natural gas leaks at their source. While gas lines rarely leak, a professional will use a detection kit to identify a potential problem. Contact a plumber if you notice a rotten egg odor; this is due to a substance added to natural gas to make it detectable to the human senses.
Other signs of a problem include:
At NexGen, we use the most advanced leak detection methods. But we can start with a water test, which can indicate a gas leak when bubbles appear on a pipe fitting. Our equipment allows us to identify the exact location, how much gas is leaking, and the type of gas it is.

We often see springtime as a relief from the harshness of winter. It is also a time when activities, such as leaving the windows open or getting a deep cleaning done, can affect indoor air quality. Indoor air pollution can trigger allergies, worsen asthma, and cause headaches, nausea, coughing, sneezing, irritation, fatigue, and a host of other symptoms.
With indoor air quality testing, you can learn whether your symptoms are occurring for the following reasons:
In most parts of the U.S., pollen counts soar in the spring. Trees, shrubs, grass, and flowers release pollen, which triggers a chain reaction in the body that causes allergies. Keeping your air conditioner filters clean or installing windowless ACs can help. Professional testing can determine if pollen, and what type, is affecting your home, so you can implement the best measures to reduce it. The best solutions are those that keep the pollen out of your home; regular vacuuming or installing air purifiers or high-efficiency particulate air (HEPA) filters can help.
In addition to pollen, numerous biological pollutants can cause poor air quality in your home. Testing for mold, viruses, and toxins from microorganisms can help determine what steps to take. Mold spores are present indoors and outdoors and can stick to just about anything. When mold grows, it can cause respiratory issues even in healthy people. Testing is a good idea especially if you see visible mold; so you can take the appropriate actions.
Dust mites are another biological pollutant that can be reduced by keeping indoor humidity levels below 50%. You can also put impermeable covers over your mattress and pillows, and washing bedding in hot water. Removing dust with a damp rag and allergens with a vacuum can get rid of them as well.
Household products such as cleaners, disinfectants, paints, stored fuels, wood preservatives, furnishings can emit vapors and gases. Within these gases, volatile organic compounds (VOCs) can be often be found. These VOC’s are extremely toxic and cause a wide range of symptoms as well as organ damage.
Testing for VOCs should be done by an accredited lab to ensure accurate results. You can often reduce VOCs by increasing ventilation, discarding old chemicals, and using products as directed by the manufacturer. Some particularly concerning compounds include benzene, a known carcinogen found in paints, fuel products, and tobacco smoke, as well as perchloroethylene and formaldehyde.
Many people don’t realize the abundance of combustion pollutants in their homes. Environmental tobacco smoke, or secondhand smoke, contains thousands of potentially harmful compounds. It has resulted in thousands of deaths among non-smoking adults and respiratory conditions in children. Parents who smoke unknowingly put their kids at risk.
Carbon monoxide (CO) is also a combustion pollutant. The colorless, odorless gas prevents the blood from absorbing oxygen and, in high concentrations, can be deadly. It can originate from unvented space heaters, fireplaces, woodstoves, and gas stoves as well as damaged or poorly maintained furnaces. While air quality testing can help detect CO, the U.S. Consumer Product Safety Commission (CPSC) recommends use of UL-approved carbon monoxide alarms and regular inspection of fuel-burning appliances.
A radioactive gas, radon occurs naturally in soil and can move up from the ground, through cracks and holes in a foundation, and into your home. Breathing in radioactive particles can cause lung tissue damage and, in some people, lung cancer. The U.S. Environmental Protection Agency recommends testing for radon in any home below the third floor, starting with a short-term test and another after a high result. A long-term test can provide a clearer perspective of radon levels present year-round. If radon is high in your home, you can install a vent pipe and fan to address the problem.
In addition to allergies, asthma, and irritated eyes and throats, there are even more greater health concerns associated with indoor air pollution. High levels of lead can cause convulsions, coma, and death, but long-term exposure to low levels can cause central nervous system and brain damage; it can harm the kidneys and blood cells as well. In children, it can lead to a shorter attention span, behavioral problems, and a lower IQ.
The effects of mold, tobacco smoke, carbon monoxide, and VOCs are well-known. For the health of your family, it is important to consider indoor air quality testing if you haven’t done so already. The everyday cleaning products you use may be putting your health at risk as well. These are just a few important considerations to think about this spring.

As you prepare for the summer months, you may ask yourself, “Do I need an air purifier this summer?” This is a valid question since the clear skies and warm weather of the summer months do not typically coincide with seasonal allergies.
If you’re prone to seasonal allergies, you know that they happen all year-round, regardless of the weather. An air purifier significantly improves your breathing throughout the summer, and below we will outline exactly how that is achieved. But first, let’s define what an air purifier is.
An air purifier is a device placed inside the home that is known to remove contaminants and pollutants from the air. It provides many health benefits and prevents respiratory illnesses. Air purifiers range in size and price, but their ultimate goal is the same - to improve your breathing.
Now that we know what air purifiers are, let’s talk about their benefits.
Air purifiers do not just combat allergies but also help improve the quality of your breathing. They perform well to ensure that your breathing is optimized, regardless of the outdoor environment. Here are some of the ways in which an air purifier can help you breathe easier:
In our post-COVID era, airborne contaminants are a real concern, and clean air has become a priority for many. Even the cleanest homes end up with contaminants that can carry various viruses, seasonal pollen, and dust.
Air purifiers provide an additional layer of protection against these contaminants, prolonging and improving the health of everyone in your home. They remove harmful particles from the air and neutralize their function.
Air purifiers promote air circulation by eliminating pressure drops that prevent the air from flowing. When air flow decreases, HVAC efficiency slows and makes your AC work harder to cool your home. Air purifiers prevent this from happening by keeping the air pressure constant, thus improving the efficiency of your HVAC system.
Air conditioning diseases are another valid concern during the summer months. These diseases are caused by the water that your AC unit uses to cool the house. Pollutants such as aerosols form in this water and circulate through the air as your AC works. Because of the shut windows and doors, these pollutants stay within your home and can negatively impact your health.
Air purifiers have the remarkable ability to remove these pollutants from the air and prevent illnesses among the members of your household. They kill off bacteria and clean the air, allowing a safe and healthy environment for you as you hide away from the heat.
Air purifiers are air cleaning devices that remove particles of dust, bacteria, and pollutants from your home. They promote safe and easy breathing all year-round, including during the summer months. With the help of an air purifier, you will find yourself breathing easier and feeling healthier than ever before.
Have you ever wondered about the quality of the air inside your home or office? Many people are concerned about air pollution outside the house, and rightly so, but indoor air pollution is just as harmful. With the prolonged hours we spend inside, air quality is important for our health and well-being. This article will discuss some of the statistics surrounding indoor air quality, its importance, and what services can help improve indoor quality.
What is indoor air quality like for people around the world and in our country? We found some interesting data that is worthy of mention and concern.
According to the World Health Organization (WHO), 3.8 million people around the world die prematurely each year from illnesses produced by harmful household air that results from using solid fuels and kerosene for cooking. Of these deaths, 27% die of pneumonia and ischaemic heart disease. WHO reports that almost half of these deaths are among children of 5 years of age and younger.
WHO also reports that household air is the cause of many non-communicable diseases like stroke, heart attacks, lung cancer, and chronic obstructive pulmonary disease. Many of these diseases are the result of using cooking methods that pollute the air with harmful chemicals.
The American Lung Association also reports that in 2018, 41.9 million Americans were diagnosed with asthma. Poor indoor and outdoor air quality explains these asthma diagnoses. According to the Centers for Disease Control and Prevention, these statistics can also be presented by secondhand smoking, known to have caused 2.5 million deaths in nonsmokers.
Air pollution inside and outside the home continues to be a persistent problem in many countries around the world. According to Our World in Data, out of the 7 million people who die from diseases caused by air pollution, 4.2 million die from outside air pollution and 3.8 million from inside air pollution.
The statistics surrounding indoor and outdoor air quality are both alarming and disheartening. According to the statistics we discussed above, the chances of contracting a disease resulting from poor air quality are almost equal inside and outside the house. This explains why indoor air quality is so important.
Air quality inside your home greatly impacts your and your family members' health. The chemicals produced while cooking or construction materials used in the structure of your home must be properly filtered in order to prevent toxic air. Though many construction materials are now made with safer materials, one cannot be too careful in ensuring safe air quality within their home.
Indoor air quality ensures that there are no harmful fumes or gasses inside the home or mold spores floating in the air. It provides a healthy home structure and healthy lives for all. If you're moving into a new home, make sure to ask about the air quality, the materials used in the home's construction, and the history of indoor cigarette smoking.
It isn't a secret that indoor cigarette smoking significantly compromises the home's air. It infiltrates the walls and stays permanently inside the house. Additionally, it causes second-hand smoking for those who aren't actively smoking a cigarette, creating many health challenges that include asthma, chronic obstructive pulmonary disease, and others.
Though using indoor air filters and thorough cleaning may improve the air quality, it's always good to hire professional indoor air quality services. At Nexgen, we have specialized, state-of-the-art equipment and trained experts who can extract all the harmful fumes and chemicals from your home.
Indoor air quality services can help tackle the following tasks or concerns:
These services are just a starting point of what air quality services can provide. We invite you to schedule your indoor air quality check with one of our trained experts for a healthier and cleaner breathing environment.
Indoor air quality is as important as outdoor air quality. The alarming statistics about indoor quality and its health implications are a cause for concern. Hire an indoor air quality company to get started on a clean, safe slate that is good for your home and lungs.
A safe and clean environment inside our homes goes beyond the regular mopping, dusting, and storing of items in their appropriate spots. It also entails careful monitoring of possible leaks that can damage your walls, ceilings, and floors with mold. Mold needs thorough inspection and prevention, as it can cause an array of health issues.
In today’s post, we will define mold and its signs and explore the common health hazards it poses. Finally, we also discuss tips for repairing and preventing this problem in your home.
Mold is a type of fungus that grows in damp areas in multicellular form. The development of mold is caused by excessive condensation and plumbing leaks. Over time, mold grows and reproduces, releasing spores that float through the air and settle on other parts inside the home. The biological composition of mold can increase a person’s sensitivities, causing increased allergies and other respiratory challenges.
You can watch out for several signs if you’re concerned about mold in your home. These signs manifest both in the house and, in some cases, in your health as well.
One of the first indicators of mold is a bad, rotten smell from the walls and floors. If you’re doing all you can to mask the smell and nothing is working, mold is probably the culprit. That musty smell is distinct and will indicate a pressing problem of mold inside your home.
Mold grows fairly quickly and spreads to other parts of your home if it isn’t addressed in a timely manner. If you see black spots on your walls, tables, ceilings, or floors, that is a sure tell-tale sign of mold. Also, if you notice puffy, slimy blotches of fibers on your clothing, you may have a very extensive mold problem in your home. Immediate action must be taken to address the situation.
Carpets are a breeding ground for mold. If you have unusual dark spots on your carpets and rugs or questionable odors, you may have a mold issue. Be sure to check both sides of the carpet to ensure you aren’t missing any concerning spots.
We will further explore the implications of mold on your health in this article, but if you notice an increase in headaches, allergies, and asthma, there's a chance that you're dealing with a mold problem. Be sure to inspect your environment for any signs and call a professional to help you.
Mold causes various health conditions. If you experience any of the following health conditions without any other underlying problems, your home may need to be inspected for mold.
Are you getting an increased number of episodes of a runny nose, congestion, or difficulty breathing? One can have seasonal allergies, but if you notice that they are consistent, your environment may have changed. As we stated before, mold heightens your body’s sensitivities; it weakens the immune system and causes it to react to allergens. Additionally, it can get into your lungs, causing respiratory problems such as asthma.
Mold has a biological component that is toxic to a person’s cognitive function. It can cause frequent headaches and even brain fog.
If you or someone in your home is constantly coughing or sick with a cold, your home may be infected with mold. Exposure to mold for extended periods eventually increases those symptoms and worsens your respiratory problems. Contact your doctor for a thorough examination and watch out for common signs of mold. If you have a history of respiratory issues, they will also get worse with mold.
Some of the most toxic forms of mold, like Stachybotrys and Aspergillus, are especially harmful because they produce mycotoxins. If they get into the lungs, they may cause serious health complications like bleeding in the lungs. For this reason alone, we encourage you to contact a mold inspector as soon as you see or suspect mold in your home.
Now that we understand the risks that mold brings, how can we ensure that it doesn’t harm our homes and health? This can be done simply through leak detection and repair services.
Leak detection is a service provided by highly trained professionals like NexGen. We are trained and certified to inspect your home for possible leaks. As mold is caused by excess moisture and water damage, early detection can help prevent the development of mold and its spread.
Once we detect a leak in your home, we will be able to provide the necessary repairs to stop that leak. This will be an essential measure to prevent water damage and mold. It will also save you money in the long run because repairing extensive water damage and mold removal can be very costly.
Mold is a great nuisance inside the home and can cause many challenges for the house's structure and its inhabitants' health. It is important to be vigilant and watch out for the signs of its development and spread. If you’re concerned that you may have mold or a leak in your home, contact us today for a professional inspection. It will give you peace of mind and save you time, money, and health in the long run.

It’s been years since people regularly smoked cigarettes indoors in public places and office environments. Most people don’t even smoke cigarettes indoors at home.
With the recent advent of vaping e-cigarettes, there has been a revival of the indoor smoker. Because of this resurgence in indoor smoking, we’d like to discuss how smoke from vaping can affect your HVAC system, your home, and your air quality.
Although it’s believed that e-cigarettes are a cleaner smoke than cigarettes, there are still some residues left over including nicotine and carcinogens from burnt organic materials.
So how do these residues affect your home?
Nicotine and other substances that make up smoke can move through your home’s air vents and leave residues on surfaces in other rooms of your house.
There has not been much study done to the chemical composition of exhaled e-cigarette smoke, so there may be many more chemicals involved that can lower the quality of your air.
What makes e-cigarette smoke even more unpredictable is the fact that the manufacturers of e-cigarette refill fluids have various flavors and are always changing their ingredients, making for a wild-card situation when it comes to knowing what is actually being circulated throughout your home’s air vents.
What Can you do about residues from e-cigarette smoke?
We’re not here to tell you whether you should smoke e-cigarettes or not, but if you or someone in your home does, there are a few steps to take to ensure your air quality stays optimal.
We hope you have the information needed to make an informed decision about your home’s air quality in relation to e-cigarette smoke. If you’d like to know more about air purification or would like to schedule an appointment for a NexGen technician to come over and consult you about your air quality, call us today!

If you've ever seen a brown haze of pollution hanging over your city, your most likely response may be, "Ugh. How can I avoid breathing that stuff?" But let's face it, even if you know it's a bad air day, you probably need to grab some sunshine, get in an outdoor run, or get to work.
Polluted air contains particulate matter, lead, ozone, nitrogen dioxide, carbon monoxide, and sulfur dioxide -- all of which can cause problems in people with allergies or asthma. Even if pollution is low, airborne pollen and mold can make a trip outdoors particularly daunting for people with respiratory conditions.
How to tell if it's a bad air day
The first step toward protecting your lungs is to know your city or town. More than 115 million people nationwide still live in counties with pollution levels considered potentially harmful to their health.
Air quality varies widely around the United States. Ozone, for instance -- which can pose a major problem for asthmatics -- tends to be more prevalent in urban areas like Los Angeles, though it can be found in suburban and rural areas as well. If you live in Fargo, North Dakota -- one of the cities with the cleanest air in the nation -- you are likely to breathe easier than if you live in Los Angeles, which has the highest ozone levels in the country.
Local weather stations often provide this information on their websites, and radio stations typically give ozone alerts. In addition, many websites can tell you if pollutants, ozone, or pollen counts are high in your area on any given day.
However, it's not just pollen or air pollution that can trigger problems. Dr. Michael Benninger, M.D., the chairman of the Head and Neck Institute at the Cleveland Clinic, in Ohio, says changes in barometric pressure and temperature can also spell trouble for people with allergies to pollen and mold, people with severe sinus symptoms, and even people without allergies.
How to cope with bad air days
Once you've figured out what factors are most likely to pose a problem (usually by trial and error, or testing for allergies), and know the conditions in your area, there are several things you can do to cope.
One option is to reduce excessive exposure on days that might trigger symptoms. For example, Benninger recommends avoiding areas where pollen, mold, or other allergens are high. If you know that grass and trees are a problem, don't spend the day in a lush, tree-filled park; if you have to mow your lawn, wear a mask with a filter to reduce exposure to grass. Staying indoors with the windows closed and the air-conditioning on is also helpful, Benninger says.
Flowers are blooming, the grass is green and lush, and trees are bursting with new leaves… Don’t you just love this time of year?
Not so much if you have allergies.
When the pollen count is out of control, all you want to do is hide in an air-conditioned room until fall. Unfortunately, that probably won’t help.
You might think your air conditioning system will filter out all those nasty allergens from the air, but without the right air filters for allergies, you’ll still be sniffling and sneezing your way through the season.
And it’s not just pollen you need to worry about! The summer heat and humidity make the conditions ripe for the growth of mold and mildew, which can also bring on allergy symptoms.
Learn the facts about choosing the right air filters for allergies, as well as other HVAC maintenance tips that can reduce your suffering this season.
Regular HVAC filters are intended to protect the equipment, not your lungs and sinuses.
Many people mistakenly believe that the air filters in furnaces and air conditioners keep dust and allergens out of the air.
That’s not what HVAC filters are designed to do. Their purpose is to keep dust out of the equipment to prevent damage to the system and keep it running efficiently.
While ordinary furnace and ac filters do help to remove some dust from the air (when changed regularly!), they do little to trap the microscopic particles that cause the sneezing and wheezing of allergy season.
That’s why you need special air filters for allergies that are designed to stop those tiny particles.
Ordinary paper filters can’t trap allergens.
Those paper filters ordinarily used in your furnace and air conditioner are designed to trap large particles like dust that can accumulate on the motor and fans and reduce efficiency. However, particles like mold, bacteria, and certain types of pollen are much smaller in size, so they slip right through the fibers of those regular filters.
That means they get circulated through your ductwork and blown back into your space.
Air filters for allergies are designed to block much smaller particles, so your air stays cleaner. They are called “high energy particulate air filters” or more commonly, HEPA filters.
Because HEPA filters are made from densely packed layers of glass fibers instead of paper, the best ones can trap more than 99 percent of pollen, buy ativan dust and smoke particles and keep them out of the air you breathe every day.
All HEPA filters are not created equal.
Unfortunately, it’s not good enough just to look for a HEPA filter for your air conditioner. To get the best results, you need to check the MERV ratings.
HVAC HEPA air filters for allergies are rated on how well they block particles of different sizes. The rating system is called the minimum efficiency reporting system, or MERV. The ratings range from MERV 1 to MERV 12, with the higher number indicating filters that can remove the smallest particles, including many species of pollen.
Your HVAC service professional can help you get and install the best MERV-rated filter for your air conditioning and heating systems. Ideally you want to choose a MERV rating of 10 or higher, which are most effective at blocking the particles that cause allergy symptoms.
You need to change those filters more frequently than you think.
HEPA air filters for allergies need to be changed more frequently than ordinary paper HVAC filters, especially during high pollen season.
That means changing them at least every other month, and possibly more often depending on your location. An HVAC service expert can advise you on what’s recommended for your equipment and your area.
The right filter is only half the story.
Using the right air filters for allergies does help to reduce the allergens in the air, but don’t forget about cleaning it from the rest of your HVAC system. If you haven’t had your air conditioning system maintained at least once every year, you’ve likely got quite a bit of buildup on the blower fans and in your ductwork.
Did you know that the air you breathe cycles through your HVAC system about 5 to 7 times each day? If you have not been using the right HEPA air filters for allergies AND not maintaining your air conditioning system, years’ worth of dust, pollen and even mold spores are sitting in on your equipment and in your ducts right now.

Most home heating and cooling systems, including forced air heating systems, do not mechanically bring fresh air into the house. Opening windows and doors, operating window or attic fans, when the weather permits, or running a window air conditioner with the vent control open increases the outdoor ventilation rate. Local bathroom or kitchen fans that exhaust outdoors remove contaminants directly from the room where the fan is located and increase the outdoor air ventilation rate.
It is particularly important to take as many of these steps as possible while you are involved in short-term activities that can generate elevated levels of pollutants — for example, painting, paint stripping, heating with kerosene heaters, cooking, or engaging in maintenance and hobby activities such as welding, soldering, or sanding. You might also choose to do some of these activities outdoors if you can and if weather permits.
Advanced designs of new homes are starting to feature mechanical systems that bring outdoor air into the home. Some of these designs include energy-efficient heat recovery ventilators (also known as air-to-air heat exchangers).
Ventilation and shading can help control indoor temperatures. Ventilation also helps remove or dilute indoor airborne pollutants coming from indoor sources. This reduces the level of contaminants and improves indoor air quality (IAQ). Carefully evaluate using ventilation to reduce indoor air pollutants where there may be outdoor sources of pollutants, such as smoke or refuse, nearby.
The introduction of outdoor air is one crucial factor in promoting good air quality. Air may enter a home in several different ways, including:
Infiltration occurs in all homes to some extent.
Natural ventilation describes air movement through open windows and doors. If used properly natural ventilation can at times help moderate the indoor air temperature, which may become too hot in homes without air-conditioning systems or when power outages or brownouts limit or make the use of air conditioning impossible.
Natural ventilation can also improve indoor air quality by reducing pollutants that are indoors. Examples of natural ventilation are:
Most residential forced air-heating systems and air-conditioning systems do not bring outdoor air into the house mechanically, and infiltration and natural ventilation are relied upon to bring outdoor air into the home. Advanced designs for new homes are starting to add a mechanical feature that brings outdoor air into the home through the HVAC system. Some of these designs include energy efficient heat recovery ventilators to mitigate the cost of cooling and heating this air during the summer and winter.
When adding outside air in order to dilute the pollution within your home is not there are a few other options. HEPA air purifiers which are separate from your homes HVAC system can be effective. If this is not an option many newer homes have an air filter cabinet located on top of or underneath the furnace depending on whether it is an upflow or downflow model, putting a charcoal or other type of particulate filter in can help reduce pollutants within the home.
