Sealing duct leaks keep more of your conditioned air traveling to your living areas, rather than allowing it to escape the duct system. Duct system allows your geothermal heating system to work less to keep your home comfortable. When air is lost through breaks and openings in the duct system, your geothermal heating system has to work longer and harder to make up for the loss, using more energy than it really needs. By decreasing the run-time of your system, you will lower your energy bills even further than you already have by installing a geothermal heat system.
Your duct work is likely located in an unconditioned area, like your attic, crawlspace, or basement. If your duct work is easily accessible, you can perform an inspection and the necessary sealing to improve the performance of your duct work. Check for:
- Loose joints and fittings
- Fallen duct work sections
- Gaps around connections to registers and return air grills
Duct sealing can be a simple procedure, but many homeowners don’t know the right technique. Contrary to popular belief, duct tape shouldn’t be used to perform lasting duct work repairs. A compound called mastic should be applied to the duct work, as it dries solid and provides a permanent fix for duct issues. If you cannot easily access your duct work, it is best to call in a professional to perform safe and reliable duct sealing for your home.
Duct sealing is a great way you can improve the performance of your geothermal heating system. Simple solutions like duct sealing can result in major energy savings, and help improve the lifespan of your equipment.
