ABBCO Heating and Cooling is based at 8160 Farnum Ave in Warren. We repair steam boilers in homes built mostly between 1940 and 1970, serving every Warren ZIP code and the surrounding Macomb County suburbs.
(586) 742-3429According to the United States Census Bureau, the median Warren home was built in 1965. Builders in the 1960s and earlier put in steam boilers and cast iron radiators as standard, most of all in south Warren's 48089 ZIP, which is largely 1940s and 1950s housing. Seventy years on, many of those first systems still sit in the basement. They need a technician who knows one pipe and two pipe steam, not only forced air furnaces. Keeping those original systems running is the everyday work behind our steam boiler repair Warren MI service.
One pipe and two pipe steam, cast iron radiators, and the Weil McLain, Burnham, and Peerless boilers common in Warren homes from this era.

Steam boiler repair specialist with 18 years of experience on cast iron steam systems across Warren and Macomb County. Gary works exclusively on one pipe and two pipe systems in the brick homes built here between 1940 and 1975. Licensed Michigan mechanical contractor verified under LARA. Every ABBCO job dispatched through this service is completed by Gary or a technician working under equivalent credentials.
Gary has never worked on a forced air furnace professionally. Eighteen years of diagnostic work on Weil McLain, Burnham, and Peerless boilers in Macomb County homes, the brands and eras that Warren was built with.
In Michigan, boiler installation and major repair work require a mechanical contractor license. Gary has one, verified through the Department of Licensing and Regulatory Affairs. Any homeowner can look up a contractor's license at michigan.gov/lara before the job starts.
Gary lives and works in Macomb County. Same day service in Warren means an hour or two, not the end of the day. He grew up in a house with a one pipe steam system on Hoover Road and has repaired the same model of boiler dozens of times.
ABBCO operates as a local lead-to-pro service. When you call, you speak with a Warren-based booking team that dispatches vetted, licensed mechanical contractors who perform the actual repair. The technicians who come to your home hold Michigan mechanical contractor licenses, which you can verify at michigan.gov/lara before any work begins. Every job is completed under that licensed operator's credentials, with a permit pulled for installation and major repair work.
Work is performed by vetted Michigan licensed mechanical contractors. Ask for the license number when the technician arrives and verify it at michigan.gov/lara.
The number you approve before work starts is the number on the final invoice. No surprises, no additions after the fact.
ABBCO does not pay technicians on commission. There is no financial incentive to recommend work your system does not need.
We cover every Warren ZIP code, 48088, 48089, 48091, 48092, and 48093. Our trucks run daily past the GM Technical Center on Mound Road, the 12 Mile Road corridor where Macomb Community College's South Campus and Warren Mott High School sit, and Hoover Road near Paul K. Cousino High School. From Chicago Road to Van Dyke Avenue, from Ryan Road to Schoenherr Road, we know the streets and the housing stock behind them.
See Full Service AreaGary's rule is simple: root cause before parts. Anybody can swap a thermocouple and leave. We'd rather find out why the low water cutoff tripped, or why the relief valve is weeping, because the part that failed is often the symptom. Every boiler is different, and after enough years you get used to what a healthy flame and a steady water line look like on each one.
We have a lot of respect for the steamfitters who piped these Warren houses decades ago. The dead men, as old timers call them, knew you only need ounces of pressure to heat a house. When we find a system that's fighting itself, it's usually because somebody later changed the near-boiler piping, turned the pressuretrol way up, or used a radiator vent where a main vent belongs.
You see what we see. If a pigtail is packed with sludge or a steam trap is stuck, we pull it and hand it to you before we replace anything. You get a written estimate, and the number you approve is the number on the invoice. No commission, so nobody on the job gains anything by talking you into work your boiler doesn't need.
Before we pack up, we leave a record at the boiler. On a tune-up that's a combustion printout with the O2, CO2 and CO readings. On a repair it's the date, the part and the pressure setting written on a tag. We also show you how to watch the sight glass and test the low water cutoff, because a homeowner who knows those two things calls us less often.
A steam specialist diagnoses the whole system, not just the burner. That means pressure settings, main vents, pipe pitch, the Hartford Loop and the wet return. Most HVAC companies train on furnaces and treat a steam boiler like a hot water unit. That's how pressuretrols end up at 10 psi and banging pipes get blamed on the boiler.
Jobs go to Gary Kowalski, our lead steam technician, or a technician working under equivalent Michigan credentials. You'll talk to a real person when you call, and the tech who arrives works on cast iron steam systems across Macomb County every week. Ask for the license number when they arrive. A good tech won't mind.
Boiler installation and major repair work in Michigan should be done by a licensed mechanical contractor. A boiler replacement also needs a mechanical permit from the local building department in most cities. EPA 608 certification covers refrigerant, so it matters for AC work, not the steam boiler itself. Ask to see the license before any work starts.
Clear a path to the boiler and make sure the tech can reach the burner, the sight glass and the far end of the steam mains. Write down what you've noticed: which radiators are cold, when the banging starts, any water on the floor. If you have old service tags or receipts, leave them on top of the boiler for us.
Yes. We show you the failed part before we replace it, on every call. A clogged pigtail, a stuck trap or a burned out igniter is easy to understand once it's in your hand. Then you get a written estimate and decide. If you'd like the old part kept for your records, just say so.
Yes. A simple log taped near the boiler saves time and money on every future call. Write down the date, what was done, the pressure setting, and when the low water cutoff was last tested. We leave a tag or printout after each visit, and the next tech, us or anyone else, isn't left guessing what changed.
