Gas pack vs Dual Fuel Heat pump

Posted by JimmySC (My Page) on

Hi, I was wondering if someone could give me some advice on upgrading my heat/AC systems. I am in the upstate area of S.C. and live in an older home thats just about 1500sq ft. I currently have electric baseboard heat and electric a/c ( split system ). Both are WELL overdue to be upgraded. I thought I had decided on installing a gas pack( I already have the line to connect to nat. gas ) but the more I talk to people, I keep hearing how a dual fuel heat pump with a gas furnace would be a better option as far as efficiency. While I obviously want the best bang for my buck, I would like to know how these two types of systems compare in price? If I go with the gas pack, I will run new ductwork under my house so there is an expense in buying the duct and installing it. If I go with the dual fuel heat pump, I can use my existing ductwork that is located in my attic and save that expense. Opinions? Thanks in advance.

RE: Gas pack vs Dual Fuel Heat pump

Because of your location and relatively mild winters, I would recommend a split system. High eff heat pump-minimum 15 SEER with backup nat gas furnace-2 stage var speed 80% efficient.

How would you describe the insulation properties of your older home?

You could leave the baseboard electric heat in place as a backup or have it removed all together.

Ductwork system should have a comprehensive evaluation as to size, insulation properties, adequate return, leak test, etc.

Average winter temp for your location is around 40 degrees.
