If you have forced-air heating, central air conditioning, or both, your house contains a system of ductwork that sends conditioned air (heated or cooled) throughout the home. They generally work through two types of duct systems:
Supply Ducts-- Designed to blow conditioned air to your various rooms.
Return Ducts-- Sends air back to the furnace or air conditioning unit so this air can be heated or cooled.
Between both types of ducts, the air is cycled continually until your thermostat tells the furnace or AC that the right temperature has been achieved.
Making sure your ductwork is the proper size and properly installed is key to the function of your heating and air conditioning (HVAC) system.
We never overlook ductwork in our evaluations. Here's why:
Comfort: When air ducts leak, air you just paid to heat or cool escapes out of your home, meaning the air that does reach you, won't be as comfortable.
Energy Efficiency: If you're letting conditioned air leak out before it ever reaches your living area, you're wasting money without ever getting to enjoy the full benefits. If hot air from your attic or cold air from your basement is being allowed into your system, it will take more energy and money to cool or heat it so that it's the right temperature for your home.
Indoor Air Quality: If you have leaks in your return ducts, you may be sending "bad air" directly into your living space. You wouldn't want to breathe air from your crawl space all day long, but if you have an uncontrolled leak, this may be the case. Leaky ducts may also create "pressure imbalances" that keep some rooms under positive pressure and others in a slight vacuum. If this happens, you may have unhealthy air (laden with dirt, dust, pollen, allergens, and other contaminants) sucked into your home.
Safety: Pressure imbalances caused by leaky ducts can lead to back-drafting in combustion appliances such as furnaces, wood stoves and gas ranges. When this happens, you risk exposure to carbon monoxide.
Up to 40% of the energy usage of your HVAC system could be wasted through leaky ducts. It's extremely important that you include ductwork testing and evaluation in your home energy checkup.
