      A friend contracted to have a new A/C split system A/C installed in her condo on March 19. Diamond installed the condenser in the roof but did not have the correct pancake air handler. On May 5not a typo, May 5she still did not have a properly functioning system so requested Diamond to remove the system and give her a full refund. They did so on May 5. My friend waited 48 days for a working A/C system that didnt materialize. I hope in the future that Diamond makes certain they can do the complete job before accepting it.

      They replaced my AC unit, Did not work at first, then they came back several times to repair. Cut a hole in my beautiful hardwood floor 22 x 24 inches without permission. We are snowbirds and were not here, numerous phone calls to ask why, fix the floor, and make a steel grate to cover the hole. they put a white plastic cover over, my husband fell over the plastic and then they put a grate over, but as you look into it, it's a giant hole. we are so disappointed in all that transpired. Have asked the owner to come over and view, he never even returned the phone calls!I would never recommend Diamond Air.......

      Avoid this scam of a company at all costs. Their preventative maintenance program is a headache and a ripoff. Every time they call and come out, they set up an appointment with you and then reschedule it multiple times. They came out and forgot to s**** the panel for the ** back in, so it fell off. My house would not get below (90). For an entire week, my ** was sucking in hot summer air (110). I went up to the roof and found the panel off with a block of ice covering the vents. When I called and complained about it, they sent *** out to look at it, get all the ice off the vent, and clean it. Then all they said was "sorry" and left me with a $450 electric bill that month. The next time they came out, they told me there was a problem with my **, but I was so fed up with them that I told them to leave because I knew it was caused by them, and they were just trying to charge me for their mistake. The most recent incident was a call asking for another appointment. They didn't even show up on the day they were supposed to. No call, nothing. The next day,they called me saying they had tried to call me, but ****** thought they had dialed the wrong number. Then ****** told me my appointment wasn't actually due for another two months, which just shows how unprofessional this scam of a company is. ****** said they'd have their manager ***** **** me and speak to me, but I have yet to hear from them. When I asked for a refund on the remaining balance of my plan, which was still active until 2027, **** denied my request, stating that she is unable to issue a refund if there is no balance left. This is clearly untrue. I sent an email to the owner, ****** Diamond, which was clearly ignored. This company is not to be trusted.
