Black Diamond Heating & Air

I contacted this company to service my York D90 Gas furnace after looking up the manufacture directory.
I had Fidelity Home Protection insurance purchased and I called them first for problem with my furnace’s «short cycles», which wasn’t corectly repaired by contactor sent by Fidelity.
After that visit I learned all I could (I man mechanical engineer) on youtube and did try to replace the thermostat on my 2-​nd floor. That didn’t fix the problem, so I didn’t try to replace 1-​st floor thermostat.
Since I had no confidence whatsoever that Fidelity contractor ever fix the furnace, I made req. for Black Diamond’s service and I’ve heard form Mike, working for Black Diamond next day. He patiently spent 20 min with me trying to assist in possible problem and provided me with price for part/​labor for each possibility. His price was 40% lower than I paid for my Reno townhouse furnace repair with similar trouble.
After we tentatively scheduled an appointment. I decided to replace the 1-​st floor thermostat, since Mike mentioned it by the one of main reasons for my trouble and it started work perfectly after I put a new one.
So, Mike not only didn’t try to push in my throat their service, but actually helped me to save hundreds for next visit. I found it extremely rare in contractor’s world we living.
Certainly recommend this business and will use it myself.
Thank you great guys from Black Diamond!
