Don’t Let HVAC Efficiency Fall Through the Cracks
Since ductwork is mostly hidden behind walls or in the attic or crawl space, you probably don’t give it much thought. But it could be a major source of energy losses if it’s not properly constructed and well sealed. A typical house with central air conditioning and heating might lose as much as 30 percent of its cooling and heating energy due to ductwork problems.
Major ductwork repairs and duct sealing are jobs that are best left to HVAC professionals, but there are some things you can do before you call in the pros. Here are some basic do-it-yourself tips for increasing HVAC efficiency by repairing your ductwork:
- Inspect the ductwork – Look at the ducts that you have easy access to, such as those that run through closets or the attic. Take note of any duct joints that have come apart, flexible ducts that are crushed or kinked, holes in ducts, and ducts in unconditioned spaces such as your attic or crawl space that should be insulated.
- Make basic repairs – Use mastic to seal duct joints and seams. Common cloth duct tape isn’t adequate for sealing ducts since it deteriorates quickly under harsh conditions. Try to straighten any crushed or kinked flexible ducts. If they won’t hold their shape after you straighten them, replace them if they’re in easily accessible locations.
- Insulate ducts in unconditioned spaces – After you’re finished with basic duct sealing work, add insulation to ducts that run through your attic, garage, crawl space or other unconditioned areas. Heat transfer by conduction from uninsulated ducts can account for a lot of the energy losses from your system.
- Get professional duct sealing help – Major duct sealing, ductwork repairs and duct insulation jobs should be left to the pros. Your HVAC contractor can get to ducts in hard-to-reach spaces and will know how to apply the correct adhesives, clamps, screws and insulating materials to do the job right.
