most systems often have poorly sealed connections, loose fittings or disconnected duct runs. The result can be cooled air blown into your attic or hot air pulled into your air conditioning system. At higher elevations, you’re losing heated air. You also risk exposure to potential indoor air quality problems.
Many systems also have an undersized return. This limits the airflow of the system and makes the unit work harder to cool or heat your home. Right sizing and sealing the return will help your system run more efficiently and this is also covered as part of the duct seal rebate.
Sealing your home’s duct system to keep your heating and cooling costs low and ensure healthy indoor air quality.
