"The service for the big deal from One Choice Mechanical for air conditioner tune up was fine. It was fine. They came in and I wasn't there. My mother was able to meet the man who came over. She said that it didn't take very long and everything was fine and paid. It went just fine, it was great. It was worth the money. There were no repairs. He didn't say, well, you need this, you need this, you need this, nothing, no. It was a nice experience. I called by a day or so and set up an appointment and made sure that my mother could make it and she said yes. It was within the same week of the big deal purchase, maybe just a few days or something like that. Everything went smoothly."

"3D heating and cooling came out in middle of Thanksgiving in the evening and we're excited to be there. Very imoftmatice and walked us through every option we had. With a 27 year old system we opted to replaced. The quality of the work matched their wonderful attitudes. Will always recommend 3D to all my family and friends. Thanks Josh and the guys."

"Our AC went out on Friday afternoon. The Aire Serv repair tech, came out on Saturday morning and told us what we already knew...that our 21 yr old AC unit needed to be replaced. He gave us some tips to help it limp along until we could have a new unit installed. Bill, the Aire Serv sales rep, met us at our house on Monday. We discussed different equipment and options. He was very professional and knowledgeable. He understood we would be getting quotes from other companies and assured us that his pricing be better. After meeting with three other companies, Bill was proven right. Aire Serv was more than $1000 less expensive than the closest competitor for the same Lennox equipment. We signed a contract with Bill on Tuesday afternoon, with the install scheduled two days later on Thursday! The other companies were 2-4 weeks out on installs. The install team (Richard & Justin) arrived promptly at 9am on Thursday and got straight to work. The removal and install was smooth and painless. They finished up around 5pm and spent an additional 45 minutes explaining how the new equipment worked, how to get the most out of the system, and answering our remaining questions. We went from an old, broken AC unit to a complete high-efficiency HVAC system in less than one week. Thank you Aire Serv!"

"This is an awesome company to do business with. Spoke with Andrew and he was very responsive. He took time to not only explain what was wrong but showed me. I had a crack in my heat exchanger. This crack can let carbon monoxide into our home, which Andrew's carbon monitor device detected. There was not any sales pitch pressure. Just options and choices. The next morning he was installing a new furnace. We went ahead and changed out our air conditioner too. Andrew told me there was a rebate by our electric/gas company and emailed me everything I needed for rebate. He left everything spotless and just as clean as when he arrived. I highly recommend Comfort Zone Heating & Cooling."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"Our AC went out on the hottest day of the year. Matt with Legacy worked within our work schedules and met with us in the late afternoon. He had the problem diagnosed and repaired in under 30 minutes! Matt went further and showed me some preventative tips to help keep my AC running at its best. Things could not have gone better. A BIG thanks to Matt and Legacy Heating and Air!"
