Boiler Installation in Mulliken, MI 48861

“Mike is awesome. On the first trip out to trouble shoot our new install, he had to spend more time than I’m sure he had planned, but put in the extra effort to make sure everything was fully operational. On the second trip back he did the full start up and was more than happy to answer all of our questions. Very personable, knowledgeable, and an overall great person to work with. We’d be happy to have him back!”

“Justin and Terry were very professional throughout the whole installation of our whole home dehumidifier. They were punctual, very careful on not tracking mud into our home, made sure we knew who they were, what they were doing, if we were comfortable with/without masks and made sure we were okay with the overall setup before they began. They were courteous during the installation, thoroughly explained the system, answered every question we had, cleaned up well and made sure we were comfortable and happy with everything before leaving. We had an overall very good experience, as always with ESI. Thank you Justin, Terry, and Nick on a job well done :)”

Gas Furnace Replacement in Holt, MI 48842

“I was very happy with Justin and Terry. They were both very polite, knowledgeable, and eager to answer any questions I might have. When they left my home, they had cleaned up and you wouldn’t have known that they were ever here. Being in the construction trades myself, and what I expect from my guys who go into a person’s home representing our company, to find a company like ESI is a real pleasure to deal with. I will be highly recommending ESI Heating and Cooling to all my friends and people I deal with. Thank you ESI Heating and Cooling. ”
