"Great service. Fixed the problem in a day or less. Worked at night as well. Am definitely going to use him again.
"

"They've maintenanced my furnace before I required a new one and they've always maintenanced the new one since I got it replaced about 3 years ago. Very easy to work with. I think I've been using them since 2008."

"I highly recommend Shane Diffin from Mid Michigan Duct Cleaning. He immediately responded to my request and did the work the next day. He sent a video while he was on the job as I was unable to be home. Easy and reasonable payment available through Venmo."

"Amazingly fast service. Quoted to fix my HVAC and replace my central air unit $1,000 below a competitor! I highly recommend"

"Our A/C stopped functioning. They removed dust and debris from the coils in the 'inside' unit. They also cleaned the drainage hose that took condensation out. Unfortunately, they missed an overflow tray which filled up a few days later, overflowing above the ceiling of our living room. It soaked the plaster. We are still getting bids to fix it, but the bids are hovering in the ~$500-$700 range. VanderHyde was apologetic and fixed the problem promptly when notified, but the damage had been done. I think it was an honest oversight. But that oversight doubled the cost of the repair. I would still use them again.

"I would highly recommend this company they did a great job, cleaning my air ducts very professional and very good team of workers."

"New installation went well. I was a little upset that only 50% was covered being that the unit was 19 years old. I'm sure that parts for something that old would be hard to find. Replacement was recommended."

"He removed the old unit, and put in the new unit. A little difficulty getting the old unit out of the wall mount, but he got it out, and aided with the disposal of the old unit."
