Report
They were able to send Marc out within a few hours of my call for what I thought was a needed repair. It turned out the breaker had flipped (forehead smack) but since I already had to pay the repair call fee, Marc said he could do the yearly maintenance as he was already there. Timely, considerate, and professional - highly recommended!

From start to finish we had an excellent experience with A Plus HVAC. From speaking to Lisa on the phones(she is SO helpful, i called her many times with questions, and she was always so patient with me!) to Christian the service tech, to JD who did the install. Every single one of them were phenomenal! Im so glad we went with them! Highly recommend!

Joe was prompt and professional. He was able to answer all our questions and explained the process and next steps very clearly. We plan to install a new furnace and convert from oil to gas and add a air purifier system. We are very happy we have selected A Plus HVAC Inc for this home project!

Marc shower up on time and was very professional and knowledgeable. I am currently selling my house and there was an issue with the upstairs being a lot hotter than downstairs. Marc thoroughly went through the system in a timely and proficient manner, pointed out what was needed, his recommendations and the reasons why. I feel very confident that his report will assist very much in the sale of the house and I can hand it over knowing I had an expert look things over. Thank you
