Anyone have any experience in the HVAC field? Or recommend any local companies to give a call? I've been working with one of the local, small companies trying to get our heat pump fixed but I'm getting a little frustrated with them. The whole system was replaced just before we purchased the house (less than 2 years ago.) Twice we have had someone come out and add refrigerant. First time was under home warranty, second time on us. Shortly after that second time (January 2nd), I called them back out because it was acting up again. This time we made them actually look for a problem instead of just adding refrigerant to get us up and going. Apparently when the system was installed, the high side service valve was installed wrong and is causing us to lose the refrigerant. At least if you trust this company. We did find out that the part would be covered under warranty but the labor and refrigerant would not. Which we figured, but I can not get a true estimate from this company. I can get a basic break down of what it COULD cost, but they can't give us a definite price until they're done. Basically we'd be at their will to whatever they wanted to charge us. That isn't sitting very well with the wife and I so we are thinking of looking elsewhere for another opinion. Trouble is I don't want to end up in the same predicament, just with some other company. We have already paid this company twice to come out, so we'd prefer not to have to pay someone again, but know that we probably will have to. I see where some places offer free second opinions but those usually seem to be on new system replacements, not repair work. Anyone have any positive experiences with the HVAC companies in the Cincy/Dayton area?
