Duct leaks are common with old HVAC systems, though unfortunately they’re not immediately noticeable. In this blog, heating and air conditioning replacement company Air Pro Inc. takes a look at how to find duct leaks and what you can do to fix them.
Duct leaks are usually found at the ductwork joints and along flexible duct hoses. You can usually easily tell if there’s a leak by simply running your hand along these areas while the heating or air conditioning system is running. Some people test their ducts for leakage by lighting incense, passing it near the ducts and waiting for the smoke to swirl, while others introduce fog into the vents using a fog machine–the same kind used at rock concerts. Both of these methods enable the homeowner to see where the leaks are located.
Another sign of leaky ducts is a significant increase in your utility costs. Leaks in the ductwork allow heated and cooled air to escape where it shouldn’t, which means less of it is able to reach the intended rooms. As the HVAC system increases its output to compensate, it consumes more energy. Assuming that you’ve been keeping up with your scheduled HVAC maintenance–and having heating and air conditioning repair performed in a timely manner–leaks in the ductwork would be the only factor that could cause your energy bills to rise.
While the actual repair work will be done by HVAC professionals like us, it’s nevertheless a good idea to inspect your ducts for leaks to get an idea of what you’re dealing with. If they’re found to have too many leaks, a replacement may be the best option. Also. be on the lookout for spots repaired by duct tape; despite the name, duct tape should only be used for temporary repairs.
