Advice on selecting HVAC System?


The air on an old Carrier split system Propane Gas/Air Conditioning unit is not keeping up in 90+ temps. The tech says that the readings on the compressor indicate that it is pretty much toast. The unit is running just about constantly. So, I guess he's probably right, right? I think the system is about 10 years old at this point with no way of knowing how well it had been maintained prior to the past two years.

I am having trust issues from recent bad contractor experiences. Yes, I am having more than one contractor bid. Any suggestions on finding a good and honest hvac contractor? Many reputable folks in my area don't belong to the BBB. That being said, the same hvac contractor recommends a hybrid propane/heat pump as I would need to upgrade my electric service to 200 amp for a heat pump only.

Any suggestions on systems and/or brands?? I am seeing some comments that Goodman products don't last past 8 years, although they offer the same warranty on parts as Carrier. Have they gotten better in recent years?

BTW: (I need to think about resale in the next few years, so what makes the most sense in a down market and a generally lower middle class neighborhood? Upgraded electrical power or a more economical heating system? I know that the electric wire should be placed higher than it is at the house, probably not up to code.)


Thanks,
Just a Girl

I'd get a second opinion on the compressor. Some techs condemn compressors when they don't know what is causing the problem.

Advice on selecting HVAC System?


did he do anything else? check/clean the evaporator or condenser coil? verify the charge? what exactly did he do to identify that the compressor was "bad"? i would say that you would need to at least add/pull some gas to see if the pressures go up or down, not sure what all would differentiate a low charge condition vs. a compressor pumping issue.

Agree
As far as makes are concerned it's not really the name but how they are installed. For any big name brand you must be a registered dealer and you are put through a screening process, so the installs are done to a higher level.
