8-9 year old lennox 4 ton system for the downstairs.
I live in DFW area (Texas) and had my compressor die (the compressor is shorting out). The compressor is still under warranty, but the uncovered labor/parts to replace it (and replace some capacitor or something else with it) is significant- about the cost of the compressor itself. Now the a/c isn't THAT old, and it was a nice lennox unit so I'm guessing maybe around 11 seer with age factored in. Also, we have electric resistance heat (no gas run to unit) which is costing us $$$$ in the winter ($500 electric bill last december). I have recently added more insulation, sealed things up, and had the ducts sealed (aeroseal). I was considering if this might be an 'oportunity' to get a new a/c/heat pump- eyeing about 16 seer a/c with a good heat pump.
1)So repair vs. replace? By my best estimates we spent over $1000 last year in heating electricity- so a heat pump would save about 1/2 that/year. A/c cost savings might be less- going from 11 to 16 seer, but still significant-guessing another $500 in savings. So I'm estimating $1000/year in electricity savings (more if rates go up, we're at 9cents/kwh).
2)If replace- with what. Had our first estimte to replace and was prepared for a monster price, and it was worse than I expected. I'm not afraid to pay for a quality install, but ouch. Had estimate for goodman and lennox, 13 and 16 seer. Is goodman ok? What about other makes?
3)Who makes a really good heat pump? Trying to avoid backup resistance heating as much as possible. I've heard about the carrier greenspeed, but that might be overkill.
4)any other thoughts?
