Our air conditioning stopped cooling on Thursday night. We called Andy at Marcus Heat & Air on Friday noontime and he was at the house by 4:30. It was a Friday and he could of put us off until next week or not even answer our call BUT he didn't. He came out, was nice, fair and knew shat he was doing. He explained a lot of things to us and MOST of all he got our air conditioner to cool again. Thank you, Andy!!!!

After buying a stove from Home Depot and experiencing their delivery/installers behave like storm troopers, chip our laminate counter, and then refuse to hook up my stove because the old stove connections were different from the new one, we were leery of hiring someone to take on the installation of an HVAC system. We asked friends to recommend a good HVAC technician and received three good recommendations. We called and left messages for all three, hoping that one would call back quickly as we began to wonder how to deal with the rising outdoor temps and rapidly rising indoor humidity exacerbated by a basement lacking an adequate vapor barrier. The last time our HVAC went out, mildew formed quickly both in the basement and main floor, damaging wall hangings, family portraits, even dried flower arrangements. While waiting on a call back, we searched the internet for additional HVAC technicians and read good reviews for Marcus Heating and Air. We decided to roll the dice and call. James (Andy) Marcus actually answered his phone, sounded very knowledgeable, and had that good ole can-do attitude that's becoming a rare commodity these days. He exceeded our expectations in every way. In short order, he installed a new system taking great care not to cause damage in the process. We love our new system and have found an HVAC technician that we can rely on. We believe anyone who chooses Marcus will be as impressed with his professionalism and workmanship as we.

Andy has been doing my HVAC work for about 10 years. Always on time (which is good because my time is valuable as well) and always gives very professional service at a reasonable price. I recommend him to everybody I know.
