Highly recommended, will definitely use his company for any future projects."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."

"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"

"They year previously the installed air conditioner, new furnace, new duct work, new chimney liner and a new hot water heater. They were really good. I told them my budget and they worked with me on that. They didn't laugh at me when I try to figure out how to turn my hot water heater up."

"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."
