Alison Mechanical Heating & Cooling

"In the 20 years I've been having service calls in South Lyon, this was one of the best experiences. Bill was able to work us in for an AC service call, and while here, helped with another water heater issue. I HIGHLY recommend and will be using again."

"Very happy with a fast appointment to diagnose and repair my furnace with a faulty motor. The job was completed quickly and professionally. I recommend Alison to anyone looking for HVAC service!"

"The compressor in my old condenser failed and a new unit was required. Dave gave me a quote with several options to replace the unit with an equivalent model. After some back and forth I settled on an upgraded model (went from single to dual stage). I feel that I got a good price and installation went without a hitch. I would gladly use Alison Mechanical for future HVAC needs."

"Alison Mechanical came out within a couple hours of me calling (with no prior customer experience) to fix my furnace on a very cold winter day. The service tech was polite and explained the issue. He also gave me a few tips on some minor fixes to try before having to call for service. Highly recommend"

"Allison Mechanical is awesome! They came out to inspect my moms furnace in Northville and gave all the options. No hard sell only genuine evaluation of the situation. Our tech went above and beyond installing by himself as his partner was ill. He never complained once. Outstanding workmanship! Great company. Home grown from company from small town of South Lyon. 5 stars isn’t enough! ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️"
