Duct Cleaning
According to the Environmental Protection Agency (EPA), the average home accumulates about 40 pounds of dust per year. You may see this manifest in your home in a couple of ways:

·                You are dusting more frequently than usual

·                You notice unusual odors when you cut the HVAC system on

·                There are visible dust build-ups on your vent grills

·                You observe streaking or black marks around your vent grills

·                You or any family members begin to suffer from allergies or respiratory issues              within the confines of your home

Such signs indicate the need for an expert air duct cleaning, which Downing Heating & Air can provide. We thoroughly clean Heating and Cooling Ventilation (HVAC) Systems to eliminate dust, pet dander, and other allergens from residential and commercial systems.
Dryer Vent Cleaning


Fire Prevention
The U.S. Consumer Product Safety Commission estimates that clothes dryers are associated with approximately 15,600 fires yearly. Fires can occur when lint builds up in the dryer or in the exhaust duct. Lint can block the flow of air, cause excessive heat build-up, and result in a fire in some dryers.

Energy Savings
According to recent industry studies, an excessively clogged dryer vent may add an additional $18-$24 dollars to your home's energy bill. That translates to almost $300 a year in unnecessary fees. Dryer Vent Cleaning is an important part of any homeowner's maintenance checklist, but is often overlooked. Though we understand that servicing the dryer vent may not seem like a priority it really is to you and your families’ safety.





Puron is a unique refrigerant, designed to help protect the environment. Puron is an HFC refrigerant, which does not contain chlorine that can harm the ozone layer. The most important advantage of Puron refrigerant is that it has not been banned in future air conditioning systems as the traditional refrigerant R-22 has been. Puron refrigerant is in service in thousands of systems, providing highly reliable, environmentally-sound performance.
