Air Quality


There’s a growing concern regarding air pollution. We don’t step out of our homes without scarves and other accessories that protect us from the polluted air. But did you know the air inside your house has a lot more contaminants compared to that outside your house? How can you be sure that the indoor air that your children and family breathe is free of contaminants and allergens?


Conducting an air quality test has become more important now than ever. Our air quality Fort Worth services include a proper indoor air assessment, helping homeowners know the presence of the pollutants in their air and other issues before they cause health problems in their families. A proper air quality assessment detects microscopic pollutants that are otherwise left unnoticed. 

Why Do You Need an Air Quality Test?

Did you know there are more than 28 contaminants that can ruin your air quality and make your family prone to infections, respiratory disorders, and other illnesses? These contaminants include mercury, mold, fungi, metal, and allergens, which present severe health risks. 

A simple air quality check can help you get a cleaner environment where you can breathe fresh air and ensure your health and that of your family. Besides, who doesn’t like a pleasant atmosphere after returning home from a hectic day at work? You get to breathe cool, odorless, and fresh air. It’s easier to relax in such a pleasant environment. 


You may have heard of the Air Quality Index, a tool used to rank air quality based on the presence of pollutants, contaminants, and other allergens in the air. The higher the count of AQI in your home, the poorer the air quality. Even if it doesn’t cause any problems now, inhaling air full of contaminants and hazardous substances can cause long-term health issues, especially in kids who are at an increased risk of developing pneumonia and other respiratory issues. 

Causes of Poor Indoor Air Quality

We have detected air quality and installed air duct sealing in hundreds of residential and commercial spaces in Hurst, Fort Worth, and other major cities in Texas. Our technicians use state-of-the-art technology to detect even the smallest contaminant in your air quality, identify the cause of it, and take steps to purify your indoor air. We aim to make the air in your home breathable. Here’s what we believe are the common causes of poor indoor air quality.

Poor Ventilation

Poor ventilation is often linked to the buildup of mold on walls and ceilings. This mold can contaminate the air, increasing the risk of catching colds and respiratory problems, such as sinusitis. Lack of proper ventilation can trap the contaminated air in your house. CandelTech inspects your ventilation system and helps you figure out whether the lack of ventilation is the culprit behind poor indoor air quality.

Faulty Appliances

If you use the stove and oven, the smoke produced during cooking can contaminate the air, making it unbreathable. Likewise, outdated and inefficient heating and cooling systems can contaminate your air quality. These faulty appliances can also raise your electricity bills. We check your air conditioning units, heating systems, stoves, and other appliances that might be deteriorating the air quality inside. Our team also helps you upgrade these systems and bring the latest and most energy-efficient solutions into your place.


Found in your home’s ceiling, wall paint, and foundation material, asbestos is considered one of the common causes of poor indoor air quality. Asbestos isn’t found in newer apartments in the US, as the government has banned it, but it can be a problem if you live in an older building. We can detect the presence of asbestos and its effect on your indoor air quality. 


Other than these, smoking tobacco or having pest infestation in your home can affect the indoor air quality. Scheduling an air quality inspection with CandelTech is the easiest way to test the air quality in your place.

Air Duct Sealing and Insulation

The gaps and leaks in your duct system are one of the common culprits of the reduced air quality in your home. Additionally, leaky ductwork makes your HVAC systems inefficient, as the fresh air from these units escapes through the leaks. This makes your air conditioners work harder than usual to compensate for the lost air. 


If you notice a sudden spike in your electricity bills, the air duct could be the problem. Leaky air ducts act as a pathway for allergens, contaminants, pests, mold, and other pollutants to enter your space and deteriorate the indoor air quality.


We know how frustrating it can be for homeowners to pay a significant electricity bill, replace their HVAC units frequently, and experience health issues just because of unsealed air ducts and poor ventilation. We can identify leaky air ducts and use sturdy material to seal these gaps, improving the air quality in your place. Additionally, sealed air ducts can make your HVAC units more efficient, as they leave no space for the air to escape. 


At CandelTech, our technicians can install new air ducts or seal the existing ones. We ensure proper ventilation in your place so that the conditioned air doesn’t escape, or the harmful particles do not enter your place through the gaps in the duct. While we are at it, we check your HVAC systems to ensure they are working efficiently.
