Frequently Asked Questions

  • Age, efficiency, and repair cost are the main factors. A boiler under 15 years old that has a specific repairable problem is usually worth fixing. A boiler over 20 years old that's been repaired multiple times, running inefficiently, or failing on a major component is usually a replacement conversation. We'll assess it and give you a straight answer with the math behind it.

  • Yes. Residential hot water and steam boilers, commercial boilers, and hydronic systems of all sizes. Repairs, replacements, and new installations for both.

  • All of them. Weil-McLain, Burnham, Peerless, Navien, Bosch, Lochinvar, Triangle Tube, Crown, and more. We don't turn away jobs based on brand.

  • Yes, and this is worth mentioning because a lot of contractors won't. Steam systems require specific knowledge of traps, vents, piping, and water chemistry that most HVAC technicians don't have. We work on steam boilers regularly and know what they need.

  • Yes. Annual boiler tune-ups and preventive maintenance for residential and commercial systems. A boiler that gets serviced once a year runs more efficiently, lasts longer, and is far less likely to fail in the middle of a cold snap. It's worth doing.

  • "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."
