Frequently Asked Questions

  • We hold five mechanical licenses, which include the credentials required for commercial refrigeration work — not just HVAC. That's an important distinction. Not every contractor who does residential AC work is licensed to touch a commercial walk-in.

  • Yes. Any brand, any age, any equipment type. Walk-ins, reach-ins, ice machines, bar coolers, prep tables — we service all major commercial refrigeration brands and we don't turn jobs away based on manufacturer.

  • We carry liability insurance under State License #7119108. That meets the threshold of most commercial property managers and major clients. If you have specific insurance requirements, call us and we'll confirm.

  • Yes, and that's actually one of the things that sets us apart. Most HVAC contractors aren't licensed for commercial refrigeration. We are — walk-ins, reach-ins, ice machines, bar coolers and kitchen equipment. One contractor for the whole kitchen - including hot side equipment.

  • Yes. Commercial refrigeration equipment that gets maintained regularly runs better, lasts longer, and fails less often at the worst possible time. Our maintenance agreements include scheduled visits, priority service scheduling, and labor discounts on covered repairs.

  • We're based in Milan and cover Southeast Michigan from the Ohio state line north through Monroe, Adrian, Jackson, Ann Arbor, Ypsilanti, the Detroit Metro area, and up to Flint. A travel fee applies beyond 20 miles from our base. Not sure if you're in range? Call or text and we'll tell you straight.

  • "Furnace went out on a Wednesday night in January. Called at 8pm half expecting to get a voicemail. He picked up, was there within two hours, and had it running before 11. Didn't charge me a penny extra for the time. That's rare."

    — Kevin in Monroe

  • "Had a new dual fuel system put in last fall. He walked me through exactly what I was getting and why, didn't oversell me, and the install was clean. Heating bills are down noticeably compared to last year."

    — Brenda in Tecumseh

  • "Our walk-in went down on a Friday before a busy weekend. He came out same day, diagnosed it fast, and had us back up before dinner service. Knows commercial equipment cold. Won't use anyone else."

    — Tony in Saline

  • "I'm picky about who I let in my house. He was on time, explained what was wrong without talking down to me, fixed it, and cleaned up after himself. Straightforward guy. Exactly what you want."

    — Sandra in Ann Arbor
