I highly recommend A-Plus Mechanical... After attempting just about every possible do-it-yourself fix on our condos malfunctioning A/C I decided it was time to call in the pros. Several of the neighbors I had talked to recommended this small company so I decided to give them a shot. The mechanic they sent, Will V., was honestly one of the nicest and most accommodating guys that I have ever delt with. He diagnosed my problem in a matter of minutes, while walking me through the entire process (no sketchiness what so ever). Then spent a good part of his day driving around town in search of the correct part for my unit (a unit which has been discontinued for 10 years now). He even gave me his cell phone number, and even more surprisingly answered my call at 8:00pm while at home with his family... Anyways, not only was my problem fixed in a very timely manor by a mechanic that I cant say enough good things about. It was also done at a fair price (believe me, I looked into parts prices etc)... As seldom as its needed (fingers crossed) I am happy to say that I now have a heating and A/C place that I can trust. Which really means a lot to me. Thanks A Plus Mechanical!
