replacement system for a small house
I've been reading this forum for a couple of hours, looking for information to help me decide on a replacement system for a 10 yr old American Standard. I've liked it, except for the draftiness of the heat pump in the winter. AC is required here for about nine months of the year, and heat or nothing the other three. The AC works great. My summer and winter indoor temps. are set at 76 and 68 (occasionally 66).
Here are the numbers (model or serial) taken from my written estimate 10 yrs ago, for my all electric system. It's a 10 SEER, with an F200 Honeywell whole house filter, 2 ton. I would consider replacing it with the same or similar system if the heat pump is as far gone as I think it is, but I haven't had it looked at yet
Air handler TWE024C140A
Cond. Unit 6H0024A100A
Heat Strips BAYHTR1410
If it is a good idea to replace my current system with the same or similar system, I'll do that if a first or second repairman suggests it (with a 13 SEER or maybe 14 SEER), and just add a second sweater and blanket in the winter. If it's not a good idea to replace this model with a current version of it, I have a couple of questions.
1. Are two-stage compressors and high efficiency single stage furnaces (non heat pump) only used in systems larger than mine?
2. Would these two items help lower my utility bills?.
My objective is to lower my utility bill. Here in north Florida we have the highest utility rates in the state (and recently had a rate increase). A $137 electric bill for 1200 kw last month is pret-ty high, considering that the fees, service charges, fuel adjustment costs, etc. brought the total bill to $186 (my average total bill is $140 to 160, with the occasional $110). Before the rates went up, half of my bills in any given year were under $100.
We have one large company that installs American Standards here, a company which until recently has had a good reputation, and two other, independent people who could install a new system for me. Reliability of HVAC people in this city is only fair, unfortunately. They don't even blink when they say: we don't give written estimates. The company that installed my current system is out of business.
I have a 32 yr old well insulated, almost 1,100 sq. ft brick house, with a new roof, R-38 in the attic and R-11 in the outside walls.
I would soooo appreciate some advice.
