Make sure your home is safe & healthy with smart indoor air improvements

Is your house harming your health? Because the average American spends about 90% of his or her time indoors, indoor air quality (IAQ) is a very important issue. In fact, there’s even a name for the various illnesses associated with indoor air pollution: Sick Building Syndrome. Respiratory ailments, allergy symptoms, eye irritation, and frequent colds are some of the most common illnesses caused by indoor air pollution.

Because there are many sources of indoor air pollution (see “Common sources”), your healthy home strategy needs to involve awareness and improvements in different areas.

As an experienced HVAC contractor, Pelletier Mechanical Services, LLC has the tools to accurately assess your home, recommend the proper repairs and/or upgrades, and provide a no-obligation quote for all work.

We provide indoor air improvements in Bristol, Litchfield, Waterbury, Torrington, and the surrounding areas. We repair, replace and install furnaces, boilers, and air conditioning; and we also offer air duct repair, maintenance, and sealing.

Here’s a short summary of the different steps you can take to ensure healthy indoor air.

Start with the simple stuff

Make sure to enforce a no-smoking policy throughout the house. Also encourage family members and guests to use bathroom fans and the vent hood above the kitchen stove – basic ventilation equipment that rids your home of odors, excess humidity and (if you have a gas stove) combustion byproducts.

Another basic method for improving IAQ is to change the air filter on the main plenum of a forced-air HVAC system.  


Be a smart shopper

Avoid cleaning products that contain strong bleach and harmful solvents. Today you can find a good variety of “green” cleaning products at most supermarkets. Make sure to buy furniture and home furnishings that don’t contain formaldehyde and other harmful VOCs (volatile organic compounds). These pollutants cause problems as they outgas from fabrics and furniture.

Common sources of indoor air pollution in CT

  • Tobacco smoke.
  • Cleaning supplies that contain harmful solvents (benzene, toluene, etc.).
  • Cooking & bathroom odors.
  • Harmful emissions from combustion appliances (furnace, gas stove, fireplace, etc.).
  • Radon gas.
  • Mold Spores.
  • Dust & pet dander.
  • Dust mite debris.
  • Asbestos from old insulation and other old building materials.
  • Harmful compounds in paint & insecticides stored indoors.
  • Volatile organic compounds (VOCs) like formaldehyde emitted by furniture & furnishings.
  • Lead dust from old lead paint.

Test for dangerous pollutants

If your house was built before 1978, it may contain lead paint that becomes hazardous when paint flakes are ingested (by children) or when lead dust is inhaled. Do-it-yourself tests for lead paint are available online and at home centers. If your house tests positive, your local health department and the EPA website are good sources of information about protective strategies.

It’s also important to test your house for radioactive radon gas, which is emitted from rocks and soil. If a radon test shows levels above 4 picocuries per liter of indoor air, contact a local radon mitigation contractor. Radon levels can be kept permanently low with a basic radon abatement system.

Manage moisture to prevent mold & mite problems

If you can smell mold or see telltale blotchy deposits in damp areas of your home, it means you’re inhaling microscopic mold spores that can cause numerous health problems. Eliminating unwanted moisture is the best way to control mold. Make sure that bathroom fans operate properly and are ducted to the outdoors rather than into the attic. Correct plumbing leaks and keep water out of basements and crawl spaces with an effective waterproofing system. If necessary, run a dehumidifier in the basement and crawl space areas to keep humidity below 60%. These moisture control strategies will also discourage dust mites whose feces and debris also contribute to indoor air pollution.

Improve your HVAC system with services performed by our experts

Pelletier Mechanical Services, LLC can check the furnace or boiler in your home to make sure that combustion gasses are venting properly. Other combustion appliances (gas fireplace, gas-fired water heater) should also be checked to make sure that carbon monoxide isn’t being drawn into your indoor air supply.

If your house has ductwork for forced-air heating and/or cooling, it’s smart to have these air ducts sealed and cleaned. Our professional duct cleaning can help reduce the amount of dust in the air, while duct sealing can prevent “bad” air from a basement or crawl space areas from being drawn into your indoor air supply. It will also significantly improve your HVAC system efficiency, cutting your heating and cooling costs.

CleanEffects™ Air Cleaner

Designed to work with any HVAC system, the HC10 provides effective filtration to make your home’s air healthier. Unlike many other whole-home air cleaners, it doesn’t add to the cost of running your heating and cooling system.


Highest efficiency-Standard air cleaners have filters that are very dense, so they stop the dust by trapping it in a slightly porous filter. The fewer the pores the more dust it can trap. However, this not only stops the dust and dirt, but it also stops the air from moving as well. So you may not be as comfortable, and less air is cleaned efficiently. This is called pressure drop. The revolutionary Trane CleanEffects™ air filtration system has the lowest pressure drop with the highest efficiency possible.

Small particles, large effects-Particles like dust, smoke and bacteria are often .3 microns or less. At that size, allergens can get deep into your lungs because they aren’t filtered well by your nose and throat. An effective whole-house air cleaner, such as Trane CleanEffects™, can reduce the presence of potential asthma and allergy attack triggers in your home, like dust, pollen, pet hair and dander, dust mites, mildew, lint, fungus, most tobacco smoke, cooking grease, and even bacteria.

Patented innovation-Trane CleanEffects utilizes patented, breakthrough air cleaning technology to remove up to an astounding 99.98% of airborne allergens from the air that passes through the filter. It catches particles as small as .1 micron, making it 8 times more effective than even the best HEPA room filters and up to 100 times more effective than a standard 1″ filter.


  • Removal of up to 99.98% of particles and allergens from your filtered indoor air. It removes particles as small as .1 microns – 1/1,000th the diameter of a human hair – a size that eludes most air cleaners
  • Industry-leading clean air delivery rate of 1,200
  • Low operating costs, with no replacement filters to buy
  • Cleaning indicators easily visible on the outside of the unit
  • Easy to clean filters. Just vacuum or rinse once every 3 to 9 months (depending on usage)
  • Easy installation
  • Quiet operation
  • Trane CleanEffects was designed to fall well below the 50 parts per billion (ppb) FDA voluntary emission limit for medical devices. Trane CleanEffects contributes a negligible amount of ozone – less than .3 ppb to the living space
  • Typical ozone levels during the summer outdoors are at about 60 to 90 ppb, and indoor levels can vary greatly but are typically between 12 ppb to more than 80 ppb. Testing of Trane CleanEffects by third parties has shown there’s no more ozone in a home installed with Trane CleanEffects than naturally occurs in the environment already
  • Trane CleanEffects is the industry benchmark supported and verified by third parties who make it their business to know about clean air.
  • Minimal pressure drop. Delivering more clean air by volume to your living space.

Humidifiers work in tandem with your furnace system to deliver desired humidity levels throughout your home. Maintaining proper humidity levels in your home is essential to maintaining indoor comfort during the winter months. Moderate humidity levels make you feel warmer at lower temperatures, which means you can set your thermostat lower without sacrificing comfort.

Depending on the size of your home, we offer a variety of humidifiers to deliver the right amount of moisture into the air. Sizing of humidifiers is measured in Gallons Per Day (GPD), and we offer models from 12 GPD to 18 GPD.
