Did you know that according to studies by the EPA, Americans spend an average of 90 percent of their time indoors, where the concentration of pollutants is often two to five times higher than typical outdoor conditions?

As modern home construction pushes for more energy-efficient, sealed homes, air pollutants increasingly have nowhere to go.

Charles Stone Heating & Cooling is dedicated to providing all our customers with healthy, breathable air. We offer a wide range of air quality services in Cookeville and Upper Cumberland, Tennesse, to improve the health and comfort of our customers.

Our Indoor Air Quality Services include:

Air Filtration Systems

Allergens floating around the house can significantly increase your seasonal allergies, like sneezing, watery eyes, and itchy throats. Your central air HVAC system does have a basic filter installed to protect itself from dust and other airborne contaminants.

Your basic HVAC filter can be upgraded to a higher grade to help filter out some of the larger dust particles and cut down on the dust in your house. HVAC systems are only rated for certain grades of filters, however. If the grade of the filter is too high for your HVAC system, it will have trouble pulling air through the filter, which will strain your system and potentially reduce its lifespan.

Luckily, there is another solution. Charles Stone can install whole-home filtration systems that work in tandem with your HVAC system to thoroughly remove contaminants like dust, pollen, pet dander, odors, and other contaminants.

Contact Charles Stone for whole-home air filtration system installation and repairs in Cookeville, Tennessee.

Air Purification Systems & UV Lights

Air filtration systems focus on cleaning out the inert material from the air, whereas air purification systems focus on cleaning out the living contaminants from the air. Air purification systems will clean out microbial contaminants like bacteria, viruses, mold spores, dust mites, mildew spores, and other microbes.

Killing bacteria and viruses can help keep illness from spreading among you and your family. Removing mold and mildew spores from the air keeps them from easily spreading through the house.

Air purification systems use UV lights and other technology to eliminate airborne microorganisms as they go through your HVAC system.

HVAC Sanitization

Your HVAC system is a prime location for mold and mildew growth. The natural processes of the HVAC system can produce moisture, and mold and mildew feed on that moisture.

Our HVAC technicians can reduce how much condensation is in your HVAC system through the proper installation and cleaning of drainage lines. We also offer full HVAC sanitization services in Cookeville and Gainsboro, Tennessee, and the surrounding areas.

Duct Cleaning, Testing, Repair, & Sealing Services

Your duct system is crucial to transporting your conditioned warm or cool air throughout your house. If your duct system isn’t efficient, neither are your AC or furnace systems.

Duct Cleaning Services

Air ducts should be cleaned if they have excessive dust that limits airflow. The harder your HVAC system has to work to push air through your air ducts, the shorter the lifespan will be of your air handler and motor. Air ducts should also be cleaned out if there are mold problems or vermin problems.

Duct Testing, Repair, & Sealing Services

According to, in a typical American house, 20 to 30 percent of the air that goes through the duct system is lost into unconditioned spaces like attics, crawlspaces, and basements due to leaks, holes, and poorly connected ducts.

In order to have an efficient system and potentially save hundreds of dollars a year, ensure your ducts are fully repaired and without major leaks. We have equipment that will test if your air ducts have leaks, and then we’ll find and repair them.

To go a step further, we can seal your ducts using a high-tech, specialized aerosol sealing spray that will mist throughout your system and is naturally attracted to any leaks. The aerosol then attaches to any leaking points and seals them from the inside.

Whole-Home Dehumidifier System Services

As summer rolls in, so does the humidity. The air gets sticky, and after you take a shower and dry off, you still don’t feel fully dry. Humidity makes it hard for humans to sweat, thickens the air, and makes it feel hotter.

While your AC does pull some humidity out of the air, most ACs cannot keep up with the intense humidity that Kentucky produces. The best and easiest solution is to install a whole-home dehumidifier system. The system will pull the excess humidity out of the air and bring it back to a natural-feeling 30 to 60 percent.

Charles Stone installs, repairs, and maintains dehumidifier systems in Cookeville, Gainsboro, and the surrounding areas.

Whole-Home Humidifier System Services

When winter rolls in, the air dries out. This can affect your hair, skin, eyes, and throat, and cause chapped lips. The wood in your home shrinks, moving and shrinking the house, which can cause cracks in the drywall. The air doesn’t hold as much warmth, and bacteria and viruses stay in the air for longer.

To solve all these problems, install a whole-home humidifier system in your home. It will bring your relative humidity back up to our recommended 30 to 60 percent and make being home much more enjoyable.
