"I recently experienced issues with my unit, which prompted me to seek the expertise of Michael Ellison from Comfort Specialist. Upon conducting a thorough diagnosis, it became apparent that a new system was necessary, which other companies deemed too costly to repair. However, Michael offered a reasonable price point for his work, which featured exceptional craftsmanship. The end result was a perfectly functioning heating and cooling system, and I couldn't be happier with the service I received. I would highly recommend Michael to anyone seeking similar repairs."
"Michael diagnosed the problem with my AC and was able to fix it efficiently and effectively. He didn't charge me extra for weekend/after hours service. He didn't charge me extra for parts. Stand up guy. Would absolutely work with him again! Thanks!"
"100% recommend
Michael is reliable, honest, very clean
I was scared calling companies , I have bad experiences in the past with lies and prices , he did an excellent job .
Again ! 100% recommend"
"Michael did a great job installing two replacement split systems for us last week! He sent us a professional estimate, with a warranty, on the same day he came to assess our needs! He was very reasonable, flexible with his availability AND completed the installation of two units in one day, with no disruptions to our everyday life. I highly recommend Comfort Specialists! We received over five bids and some of them were going to cost more for one unit than what he quoted us for two. Thank you Michael!"
"Absolutely the best HVAC guy I have ever dealt with, and that includes my own brother-in-law. Michael came to check out our AC on a Saturday and then moved his schedule around to do the install of the new unit first thing Monday because he knew we had a time crunch. Pricing was more than fair and he went above and beyond including helping us diagnose our other unit as well."
"Comfort Specialists Heating & Cooling gets more than 5 Stars from me. After over $1000 with City Heating & Cooling, Michael came in and found instantly two capacitors shot. One had oil leaking out of it. The other was bad and it's where City changed the points and said it was good to go. It wasn't good to go and tell me they're not price gouging. Points changed on one capacitor that wasn't working and it cost $431. City can take me to court to get that $$$
If u need HVAC work do urself a favor and call Michael."
"Our air conditioner stopped working in the middle if the night, leaving us all sweating by 8:00 am. With 90°+ temps, a house full of pets, and a toddler, we were in need of a quick fix. After doing a frantic Google search and seeing all of Michael’s great reviews, he was my first call. Not only did he fit us in SAME DAY, he did so on a holiday weekend. The service was incredibly quick, and at an incredible price. I’m so, so thankful and will be scheduling routine maintenance appointments with him!"
"Mike came out promptly on a Friday night. He was very professional and got everything working for a very fair price. He explained what was wrong with the unit, showed me photos of his work, and gave me tips to keep the unit working properly. I would definitely recommend his services if you are in need of routine maintenance or in a jam and needing immediate help as I was. Very honest and fair priced services."
