Residential Duct & Dryer Vent Cleaning

The air in your home could be a problem. According to the Environmental Protection Agency (EPA), levels of air pollution inside our homes can be 2 to 5 times higher than outdoor levels. Household dust can contain mites, mold, mildew, pollen and animal dander — all of which is cycled through the central air system and circulated in your home 3 to 5 times a day. According to Total Health and Better Health magazine, 1 out of 4 people who suffer from allergies does so due to the fungi and bacteria in the air duct system. Also, did you know that "failure to clean" was the leading factor contributing to the ignition of clothes dryer fires in residential buildings? (Source) Don't be a statistic — call us today for dryer vent cleaning.

Rely on the experts at Koval Plumbing Heating and Air Conditioning Inc., to conduct an inspection to show you what you are breathing. Our technicians use a video inspection system to evaluate your ductwork. We look for dirt, debris, animal droppings, mold moisture, and more to determine whether cleaning is necessary to improve the quality of your indoor air.
