Looking for a Reliable HVAC Contractor in South Lyon, MI?

Dave is both a competent professional and an authentically friendly person. He resolved my furnace problem quickly and provided a thorough report on his inspection. We will call on him again when install whole house AC this spring.

Service was great. We just purchased a new home so we wanted to get the system inspected. He took the time to walk us through everything and made great (cost efficient) recommendations to improve some cold spots. Took the time to answer any questions and wasn't in a rush to get out (even at 6:30 at night). Definitely found our new furnace guy.

Dave came out to look at the problem with my air conditioner and also do an annual cleaning for the furnace. We talked about prior problems with the air conditioner and he was able to talk to me about possible options to resolve the issue instead of what I had gotten from the "other guy" I called this summer (time for a whole new air conditioner - want me to give you a quote?). I was impressed at how quickly Dave found the source of the problem and how everything was up and running in (literally) minutes - He did a great diagnosis (per my eyes) and found the problem. His pricing for annual furnace cleaning is competitive too. Thanks Dave!

Dave was very professional and tried his best to solve the problem but he found out it was not the furnace and then gave the furnace a clean bill so when we got the electric solved it ran rather well.

Honest, dependable, quick and the best price! Happy to recommend!

Of course during the first summer-like heat wave, everyone's AC unit will fail. Dealing with the heat and humidity for seven days before another company could come diagnose the issue was NOT an option. Super pleased with Alison Mechanical's professionalism and speed. Efficient, creative (had to get on to a 20story building), honest, and very pleasant. Thanks, Bill!

This business is built on honesty, hard work and integrity. I have used this company for every furnace and AC need and have never been disappointed. Awesome job on my difficult hot water heater.

We use Allison Mechanical for all our needs. They are fast to come out. Price is great. Equipment always runs great!

David Stark and his crew did a fantastic job in putting in my new furnace. I would highly recommend them for all your heating and cooling needs.

A great local business. Knowledgeable and friendly. They also support South Lyon Youth Athletics by donating time and money. Definitely a business to support. I highly recommend them.
