Get matched with top central a/c installers in Holly, MI

"Scheduling was easy and efficient. Tech arrived on-time and quickly diagnosed and replaced the faulty part. Will be hiring them again."

"They came out the same day we called and installed a new water heater that Mr. Rooter installed incorrectly 3 years ago."

"Zack came in to give me quote as was the only guy who was not a sales person. Value for money wise his company is excellent. He installed Tempstar furnace and Media filter. We pulled the permit . The mechanical inspector came in and said whoever did this job did it professional. Particularly he liked how the media filter cabinet was installed. We couldn't get the CWire to the thermostat. He will be coming in this week to install it. Every electrical connection were clamped to the duct properly. He also put in new drain for the humidifier. Awesome guy. Normally I would wait for atleast 6 months to a year to leave a review. In this case, because of the exceptional installation and because of the comment that inspector made i am leaving 5 star review. Will update in future if any new issues crop up. I don't expect that to be case."

"Jeff arrived to our home and provided an estimate for a new furnace and A/C system. Very professional and courteous. Seemed very knowledgeable and answered my questions easily. Spent time measuring windows and even called the city to get an accurate sq footage of the home to design the right system. Although we ended up going with a different HVAC system, I would have no hesitation recommending this company and will likely use them for any service we may need in the future. Excellent."

"Excellent! Zach Hill and his assistant completed the installation of my new furnace and central air conditioner system quickly, cleanly and efficiently. They hauled away the old equipment. The system works great, no surprises or problems! I highly recommend Hill Mechanical for your HVAC needs."

"Rebecca answered all of my calls, even on New Year's Day. She was great. The installers were also great. Anthony was a true professional and I could tell he took pride in his work. I'm very satisfied and the Trane furnace is great!"

"I was able to schedule the appointment easily via email. He actually arrived early and called to let me know when he was on his way. He not only fixed my air conditioning, but cleaned up some questionable work that had been done by someone else years ago. He was very friendly and I would 100% hire them again if necessary."

"Very professional and great prices. Hill Mechanical installed a new Furnace and whole house humidifier."

"Of course the A/C quits on the afternoon of the 90+ degree day! Fan and compressor were not working, but indoor fan was, meaning either a capacitor or contractor issue in the outdoor unit. Called office 10 minutes before they were done for the day, but was able to confirm a repair appointment for first thing the next morning. Technician (Sean) was here at 8 am, and after a 2 minute discussion and check, confirmed that capacitor was the issue. Still under warranty from Bryant, so that was a plus, but I was surprised that there was a failure after only 3 years since last unit ( also a Bryant, nd installed by AC Engineers after house was built in 1997) never had a problem for the 17 years we had it until replaced with the higher efficiency unit. The interesting comment from the technician was that he would likely replace 5-6 more capacitors that day (!!!!!), not tied to any particular brand of unit, but more because all the manufacturers use the same capacitor from the same source, and "they literally don't build them like the used too". Rather illuminating - In addition to the capacitor fix, he did a full service check of the system. Excellent job, responsive and knowledgeable."
