“McCarthy's was fast! My A/C went out and I called at the end of the work day Wednesday and they came out the following morning. Jacob Petry was our technician and he was quick, courteous, and informative. I would definitely use McCarthy's again in the future.”

“McCarthy’s service was great. I called for a dryer vent cleaning service, and the technician was over the next day. The technician Jake was wonderful. He came on time and was quick, but thorough. He described everything and talked things through with us. Overall great experience with this company!”

“I would definitely recommend McCarthy’s One Hour Heating and Air Conditioning! They were so quick to get out to help us. I booked online on a Friday morning and they were here a couple of hours later. Sam was very knowledgeable and made sure to explain everything and answer our questions.”

“We had another service come out that clearly wanted to just sell us a new system. Then we called Macarthy. Not only did they report one of the potential problems to not be a problem, but they also found the real problem. Instead of just reporting it as a potential fix, he fixed it first to make sure the unit would function with the cheaper fix. I’m very impressed with the knowledge and ability!”
