Having a properly designed duct system can be more important than the type of unit or the SEER rating!
If duct leakage is reduced, cooling and heating equipment can be downsized for additional savings. Reducing leakage can also increase cooling and heating output at registers.
An enormous waste of energy occurs when cooled air escapes from supply ducts or when hot attic air leaks into return ducts. Recent studies indicate that 10% to 30% of the conditioned air in an average central air system escapes from the ducts.
APS recommends R-6 or better – we use R-8 duct insulation for our desert climate. By insulating your ductwork, you may be able to save an additional 5% to 6% on your air conditioning bill.
