"Rex was great to work with and his pricing fair. They installed central A/C in my home in just a few hours and now I m ready for summer."

"It went well. We will use his services again, if necessary."

"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."

"Shane was prompt and provided excellent service. I’m breathing better already! ?"

"When my old air conditioner started failing, I knew it was going to be a larger project since it was using a discontinued refrigerant. Since the furnace was roughly the same age, getting everything replaced made the most sense to avoid the likelihood of having to redo a bunch of work in a couple of years. I felt comfortable throughout the process of assessment through installation, with any questions I had being expertly and timely handled."

"I went with the other contractor due to the fact they included a 7 year maintenance warranty, the company has been around for over 100 years."

"Went OK. They did the work and it 'mostly worked' when they were done. I say mostly because the pressure valve was blowing off of the boiler when they were done (This was NOT happening before they had done the work). I had noticed this the day after I had paid. I contacted them and they wanted to replace the expansion tank and charge me $200. I asked - shouldn't this be covered under the initial work of $4600? They said the part wasn't explicitly in the quote. Frankly at this point to replace what really was a $40 part and half hour of time to do a fully finished job (for $4600). For 1. How am I supposed to know (as a customer) what should be on the quote for a fully finished job (pumps, piping, etc? - they are the expert) 2. How am I supposed to know this isnt their fault. (Shouldnt an autofilling expansion tank be connected to the incoming water supply?) Frankly not standing fully behind their work and making sure they do everything to do a good, finished job - left a 'bad' taste in my mouth. In the end I replaced the auto-filling expansion tank with an Extrol expansion tank for $40 and it took me less than an hour. After that it all appears to work."

"My house is an early 1900's home. Since moving in some years back we never have had the air ducts cleaned. We contacted Michigan Home Comfort in Lansing Mi and the process from start to finish was very easy. They sent in a three man crew to do the job, it was very extensive work. They were well dressed, nice and professional throughout. They spent about three hours here at my home and they showed me before and after pictures. The air quality in our home is much better now and less dusty to say the least. I would recommend them for sure to anyone."
