“I was out of town for work when my Wife called me at 7:30am to advise me it was 54 degrees in the house. I called the office and they had someone there within 90 minutes and the furnace was working by 11:00am. They always provide great customer service. They have installed a furnace, central air, a tankless water heater and a generator for us. I will not use anyone else.”
- Chris B.

“During the recent cold snap our furnace stopped working on a Sunday morning. I called the emergency service number for support and Dan arrived shortly after I called. He spent most of the day Sunday diagnosing and attempting to repair the problem. It turned out to be a faulty component on the recently installed furnace. It took a few days to get the replacement part, so Dan set up temporary heaters to get us through until the correct part arrived. He went the extra mile to ensure our home (and water pipes) were protected in this very cold weather. Great service!”

- Steve F.

“Charged me 409.00 to charge a 20 dollar part that took 15 minutes on top of the 95 service fee . Do. Not. Call. These. People.”

- Mark B.

January 17, 2025

Winter in Kalida, is shaping up to be especially harsh this year. Can you imagine not having your furnace to help you make it through? You go to turn it on … and instead of rushing warm air through your ducts, it rattles, groans, and then just sits in sullen silence, clearly protesting another season of overworked servitude.
