Re: How to run my HVAC efficiently in the winter?
[QUOTE=HoustonRemodeler;286402]Do I get any credit for hinting at the 2 stage heat pump ??[/QUOTE]
I googled it, it does not appear that it is a 2 stage heat pump.
If you are going to replace everything, you might consider a package system where everything is located outside and the ducts go through the foundation walls. This is usually cheaper. If you have propane available in your area, you might save a lot of money by getting a gas pack or a gas pack/ heat pump combo. A gas pack is a package system with gas heat and regular AC.
A gas pack with a heat pump would use the heat pump for AC and heat on mild days and the propane for the really cold days.
One more alternative to look into would be Geothermal. The install is very expensive, $20-25k but the cost to operate is very low.
