"The experience was great. I was referred by a friend. I called and set an appointment. The technician was prompt, and very professional. He checked the furnace and described the problem. A major component had failed. He said I had a choice of either repairing the furnace, or replacement. The repair was not something I was interested in, so I chose to replace it. The replacement was done in a timely, and professional manner. I highly recommend All Temp for their professionalism, and making my furnace replacement a very positive experience."

"They handled my boiler heating system installation and wall heater repair with great care and expertise. The technicians were knowledgeable, explained everything clearly, and made sure the job was done right. I truly appreciate their reliable and high-quality service."

"They've put in a new furnace, water heater, AC, etc. They are very reliable, but not inexpensive. Everything they do is quality and they only work with quality people. I had a problem with the air compressor on our AC right after the warranty had expired. Cahill said that they work with that company all the time and that part shouldn't have gone out that quick. They said they would talk to the company and see that it is made right, and they did."

"We had a huge heat problem and Four Seasons came in and fixed it for us. They were courteous and on time. The first person came and looked at it for us and told us the issue and they were able to install the furnace the same day. I would highly recommend them for your furnace needs!"

"I hired them to install new combined water heater/ boiler, install new water filtration system and service the ac units.Great service and knowledgeable of what theyâ re doing. Definitely will hire them again."

"Friendly reliable owners and staff. Work was completed when scheduled and professionally. New AC was installed with furnace. Since it was cold out, I was assured They will check outside condenser unit in the spring. Comforting to work with a good company."

"These guys were great. Not only did they do all the furnace ducts. The proprietary dryer duct was disassembled cleaned and reassembled at their incentive. I’ve had other services show up at my doorstep with a fraction of the equipment and I turned them away. Mr. Duct is the only duct cleaning service I will ever recommend. The extra money is MORE than worth it."

"I used Toptec to install my furnace. They did a great job from start to finish. Adam was very knowledgeable and business oriented."

"We contacted them for electric furnace repair and thermostat service and they did a fantastic job. The technician explained everything clearly and made sure the heating system was working safely before leaving. Honest, professional, and dependable service."

"In May of 2021, CR Mechanical replaced our HVAC equipment (furnace and AC), and installed a new air scrubber and an ecobee thermostat. We were very satisfied with their work (exceeded expectations), and Craig is an excellent installer (that was most important to us). The ecobee was defective out of the box, and he reinstalled our old thermostat and was back the next day (as promised) to install a replacement ecobee. Everything works great."
