"Excellent. The service rep gave me many helpful maintenance tips to keep my HVAC appliances in top condition. He was prompt (actually early), well-organized, and communicated his findings well. I would definitely use All Temp again."

"I had a great experience with their HVAC services. They repaired my electrical baseboard heater quickly and made sure everything was working perfectly before leaving. The team was professional, punctual, and very knowledgeable. They also installed our new central A/C system smoothly with no issues at all. Communication was clear throughout the process, and the pricing was fair. Highly satisfied with the quality of work and customer service. I would definitely recommend them for any heating or cooling needs."

"Kyle came to inspect my condo's HVAC. He was punctual, friendly and professional. I'm a new homeowner and he patiently answered all my questions about this stuff! I couldn't get access to the ac on my roof, so he didn't get to look at that but he spent a lot of time making sure my furnace was cleaned and in good order and looked at the air vents. He found a small gas leak on the furnace and sealed it up for me, thankfully. I will definitely contact them again for anything HVAC related!"

"I needed a new HVAC. I received a prompt bid at an extremely favorable price. The technicians who installed my new unit were extremely knowledgeable and personable! They finished the job in one day, even though they had estimated it would take two whole days. They cleaned up after themselves in a marvelous way."
