Is your heating system more than 5 years old? If so, it may be time to check your ductwork. One of the most common efficiency zappers is air leaks in the ductwork system. Over time, the connection in your ductwork can separate, causing air leaks. As the air begins to leak underneath your home, your heating costs could skyrocket. The following article will teach you how to check for leaks and repair any leaks you find.
Finding leaks can be tricky if you do not understand the mechanics of a heating ductwork system. There are two types of ducts running to and from the heating system. One set of ducts blows hot air into the home. The other set sucks air from the home and returns it to the heating system. You will need to check each type of duct for leaks.
You will need the heating system to run continuously while checking for leaks. There are two ways to do this. Either turn your thermostat up very high or turn the blower fan on at your thermostat. Most homeowners prefer leaving the temperature setting alone and just turning on the blower.
Next, grab a facial tissue and a paint pen and go under your home to where the ductwork is located, starting on the ductwork nearest to your heating unit. Hold the tissue up to each duct. If the tissue is sucked up against the ductwork or blown away from the duct, there is a leak at the location. Mark the area with your paint pen and continue down the ductwork line.
Most leaks occur where two pieces of duct are connected together; however, leaks can occur anywhere along the ductwork. Once you have located all leaks, it is time to begin sealing the leaks. For best results, go indoors and turn off the heating system while you are repairing the leaks. You will need a clean cloth, some silicone caulk and a roll of foil tape to seal your ductwork.
Clean each leak location with a clean cloth to help the caulk and tape stick to the ductwork. Once the duct is clean, squeeze an ample amount of silicone caulk around the circumference of the duct and then apply the foil tape on top of the caulk. This method will create an airtight seal.
Leaky ductwork can tremendously increase your utility bills. Stop heating the great outdoors and begin reaping savings today by sealing your ductwork using the tips located above.
