Richair Comfort Solutions came out for a diagnosis of my Fujitsu ductless air conditioner. They gave me an estimate to replace it with Mitsubishi. After my appointment, there was some confusion about a bill. We were told we wouldn't be charged for the appointment since they really couldn't diagnose or remedy the problem (not really their fault - my air conditioner units are out of circulation so no replacement parts available). Afterwards, due to an apparent paperwork mix-up, we were sent a bill. Yes, we were confused and a little frustrated, but Richair eventually did the right thing and did not charge us. So when all was said and done, it was handled well. Aside from that, their technician was knowledgeable and did all he could to help solve the problem. We had other people out previously trying to figure it out and they couldn't. I'd say Richair tried a little harder, going so far as to call Fujitsu for an answer.
