My almost 30 yr old but very reliable AC stopped cooling on Sat. I messaged 3-4 places, 2 got back to me right away one being Mechanical. They came out quickly about 2hrs and got to work and quickly let me know what the problem was, showed me pictures and old and new parts, unfortunately one part was not available until Monday, so we spent The Weekend w out AC! But I was happy to have it resolved quickly even if not completely fixed. Joe came in on Monday and finished w the one part in about 15min. Everyone was friendly via message and phone and again quick. I will be getting a quote from them for a new unit in the future and will recommend their services. I actually had a couple good recommendations for other AC companies but they either were not open Sat or messaged me back to call them instead of the other way around so I took a chance not knowing anything about mechanical brothers but the reviews here. Almost did 4 stars because it was a bit pricey, but not outrageous and worth it for the good and quick service. Thx!
