Heat pump vs air conditioner (San Diego, CA)
Help. New to San Diego. We bought our home about 1 1/2 yrs. ago, without AC. Built in 2000., with 2 - 4 ton single stage Carrier furnaces. We were told not to worry, but it was unbearable last summer without AC.
We need 2 - 4 ton single stage AC units. In getting 4 bids, one company recommended a heat pump instead, and talked about the energy savings with SDG&E billing us at a baseline electrical rate, which would be less costly, the (single stage Trane XB130) HP more efficient & may be more desirable as it makes the home solar ready should we decide to sell. Another said it's not worth it because of all the extra work that needs to be done to set it up, HP can't be used with our furnace, and savings not worth it for our time frame. We were on a 3 - 5 year plan to stay in this home, but since we've been doing repairs, renovations, upgrades to home & garden it may be we would stay up to 10 yrs, but since we are putting so much into the home already, wants to go the route of the least amount of capital outlay needed, which would be the AC route. Mistake?
I can't find the information re "baseline'" electrical rates with HP at SDG&E. Are the single stage HP actually efficient, at 13 SEER? Variable and 2 stage with more SEER is better in everything. Would having a single stage HP be desirable at all, if someone would truly want to make the home energy efficient and upgrade to pv solar?
Novice to all of this, please share any experience or advice that would help us make a decision. Thanks.
