Gas Furnace Replacement in Portland, MI 48851

“We had our 50 year old furnace replaced with a gas furnace last year. The replacement was seamless. When completed, we were walked through everything that had been done and what to expect.
We were so pleased with the honesty and attention to detail that we had our air conditioner replaced this year.
From the front desk to installation to annual maintenance, we couldn't ask for any better company.
We recommend ESI to everone.”

“Great service and professionalism!! Can’t say it enough
Terry and Tristin showed up 10 minutes early! That is a big deal to me. What we thought was going to be a quick install turned into an all day job, terry never complained once. After the job was as done he was very thorough on explaining the new furnace and left our house cleaner than when he showed up.
Keep up the great work guys!”
