A second quote from another local company that's well known was anywhere from $4700 to $6500 for Carrier equipment - depending on the efficiency ratings.
A co-worker's husband does commercial HVAC for a school district and does installs on the side. He quoted me for $3700 for a similar Rheem installation.
A neighbor across the street does HVAC for a living - saw the vans parked out front and later on out of curiosity asked me how much we paid - and said he would have come under the quote from my co-worker's husband.
I don't have buyer's remorse - I was ready to go with the co-worker's husband, but my father-in-law is also our State Farm agent and he had insurance concerns and all that good stuff since the co-worker's husband wasn't bonded/insured/licensed to do the work independently. My wife didn't doubt the quality of his work or if he would stand behind it - her concern was if the installation was faulty she wanted deeper pockets to go after if something went horribly wrong. Also would he stand behind his work at 2am in January?
I didn't bother asking the neighbor for a quote first because of something went wrong with the install or if I went with someone else - I wouldn't want problems with him down the road. As a rule I don't do business with friends, family, co-workers, neighbors, etc... - would rather deal with a person I'll likely never see again - not mix business with pleasure - and deal with someone who has deeper pockets should something go wrong and we have to go into litigation.
I think what we paid was probably in the mid-range of what I could have shelled out. For our house, a higher efficiency system would unlikely pay for itself over what we had installed.
Did I get ripped - or was the $4700 I paid on par?
