Fast, Reliable Heating & Furnace Across Detroit
Heating repair in Detroit typically runs $150-$700 for most furnace and boiler issues, and our crew can usually be there same day. We’re the team that answers the phone at 2 a.m. when your boiler quits on a January night in Detroit, and we quote the price you’ll actually pay.
Fireside Heating & Air Co. has served homeowners for over 42 years. We know Detroit’s ZIPs 48208, 48209, 48210, and 48211 well - the brick bungalows along Michigan Avenue, the two-family flats near Vernor Highway, the century homes in Woodbridge with their original cast-iron radiators still clanking through winter. These aren’t houses you fix the same way you’d fix a 1990s ranch in the suburbs. They need a crew that understands one-pipe steam, sectional cast-iron boilers, and the particular damage a Detroit winter does to systems that sat cold and waterlogged. Call us at (866) 561-3358. A live person answers, day or night.
Why Fireside Heating & Air Co. Is Detroit’s Preferred Heating & Furnace Company
We’ve worked in Detroit long enough to know the difference between a boiler that can be saved and one that’s done. Glen Hartman built this company in 1984 on straight talk and work that holds up. That hasn’t changed.
Detroit homeowners call us back because we don’t treat their 1920s system like a mystery. Our technicians are trained journeymen, background-checked and uniformed, who put on shoe covers without being asked. They know how to diagnose a failed Gorton air vent on a one-pipe steam system in Boston-Edison, and they know when a scavenged copper line in a rehabbed Woodbridge flat means starting over with new piping.
Our 90-Day Done Right Promise applies to every job in Detroit: if it’s not right, we make it right, in writing, no paperwork, no arguing. The price we quote is the price you pay. And when we say we’ll be there, we’ll be there.
Most Detroit calls reach us within the hour, and most heating repairs are completed in a single visit. That’s not a slogan. That’s what happens when your technicians carry the right parts and know what they’re walking into.
Our Heating & Furnace Services in Detroit
Furnace Repair
A furnace repair in Detroit isn’t always a furnace repair. In ZIPs 48208 and 48209, what you call a furnace might be a converted gravity hot-water system or an early forced-air retrofit crammed into a basement never designed for ductwork. We diagnose what you actually have. Typical repairs run $150-$700 depending on whether we’re replacing a gas valve, swapping a failed ignitor, or tracking down why your blower won’t kick on during a lake-effect cold snap. We carry parts for Carrier, Trane, Lennox, and American Standard, and we stock common components for older systems other shops won’t touch.
Furnace Replacement
Sometimes the honest answer is replacement. A cracked heat exchanger. A boiler section frozen through after years of vacancy. A system so stripped by scavengers that repair costs more than starting fresh. When that’s the case, we give you straight talk about repair versus replace, and we quote upfront - no fine print, no add-ons after the fact. New furnace installation in Detroit runs $3,500-$7,500 depending on the house, the existing infrastructure, and whether we’re engineering ductwork into a structure that never had it. We handle the full job, including any necessary modifications to accommodate Detroit’s older housing stock.
Furnace Tune-Up
Our $89 seasonal tune-up catches problems before they leave you cold. In Detroit, that means checking expansion tanks and pressure relief valves stressed by repeated hard freezes. It means inspecting condensate lines that can ice up when lake-effect snow piles against the foundation. And for homes still running original boiler systems, it means testing safety controls and checking for waterlogged returns that signal bigger trouble coming. A tune-up costs $80-$200 depending on system complexity. For a 1920s sectional cast-iron boiler, it’s the cheapest insurance you can buy.
Heat Exchanger & Gas Valve Repair
A cracked heat exchanger is a safety issue. Carbon monoxide doesn’t give warnings. If we find one, we flag it immediately and walk you through your options. Gas valve failures are more common in Detroit’s older systems that have cycled through decades of cold snaps. We replace both components with factory-spec parts, test combustion, and verify safe operation before we leave. No shortcuts. No “good enough.”

We’re trained to service all nine major residential brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Detroit customers, that means fast turnaround because we stock common parts locally. We don’t order-and-wait while your house freezes.

Our Heating & Furnace team carries the tools and the training for both ends of that spectrum.
Common Heating & Furnace Problems We See in Detroit Homes
- Waterlogged returns and failed air vents on one-pipe steam systems. Detroit’s pre-1950 housing stock runs on steam heat that suburban techs rarely encounter. Cold radiators and banging pipes usually mean incorrect pipe pitch or a failed Gorton vent - not a “broken furnace” that needs replacement. We repitch lines and replace vents, restoring balanced heat without the cost of full conversion.
- Frozen, cracked cast-iron boiler sections in long-vacant homes. Decades of population loss left Detroit properties sitting cold through multiple Michigan winters. Water left in a cast-iron boiler expands, cracks sections, and destroys the unit. We assess whether repair is possible, but often these require full boiler replacement before the house can be safely heated.
- Scavenged copper and stolen radiators in rehabbed properties. Contractors re-entering Detroit homes routinely find stripped systems. We redesign from scratch: new piping, new radiators, properly sized for the space. It’s not a repair. It’s a full system installation, and we engineer it right the first time.
- Forced-air conversions in homes never designed for ducts. Homeowners in neighborhoods like Woodbridge want central AC, but their walls are plaster-on-lath, not stud cavities. We engineer solutions - high-velocity systems, mini-splits, or careful duct routing - that don’t destroy the structure’s integrity.

FAQs - Heating & Furnace in Detroit
Yes, we have options. High-velocity forced-air systems use small, flexible ducts that fit inside existing walls with minimal intrusion. Mini-split heat pumps provide cooling (and heating) without any ductwork at all. We’ve installed both in Detroit’s pre-1950 bungalows, preserving plaster walls while adding modern comfort. The right approach depends on your layout, your budget, and whether you want to keep your radiator heat or convert fully. Call (866) 561-3358 and we’ll walk through your specific house.
The fix is repitching the supply lines and replacing failed air vents, not replacing the boiler. Waterlogged returns mean condensate isn’t draining back properly, often due to settled pipe pitch or clogged returns. Failed Gorton or Hoffman air vents prevent steam from entering radiators. We diagnose which vents have failed, check pipe slope, and restore the system’s original balance. In the Boston-Edison corridor, we serviced a 1920s one-pipe steam system where the original sectional cast-iron boiler had waterlogged returns and failed Gorton air vents. Our crew repitched the supply lines and replaced the vents, restoring balanced heat to the radiators without a full system conversion - saving the homeowner thousands versus a forced-air retrofit. Call (866) 561-3358 for an exact quote; estimates are free.
It usually needs full replacement. Cast-iron boilers that sat waterlogged through multiple Detroit winters almost always have cracked sections from freeze damage. We inspect thoroughly, but we’ve rarely found a long-cold boiler worth saving. The real question becomes: replace with another boiler (preserving your radiator system) or convert to forced-air (adding AC capability). We quote both paths honestly so you can decide what serves the property long-term. Call (866) 561-3358 before you start demo - we’ll assess what’s salvageable.
Once a year, every fall, before the first hard freeze. Detroit’s heating season runs November through March, and lake-effect cold snaps stress aging systems hard. Annual service includes pressure testing, safety control verification, vent inspection, and checking for waterlogged returns that signal bigger problems. For a century-old sectional cast-iron boiler, that $89 tune-up is cheap insurance against a mid-winter failure when every contractor in Detroit is booked solid. Call (866) 561-3358 to schedule before the rush.
Yes. These systems are essentially lost technology in suburban HVAC training, but our journeymen know them. We diagnose incorrect pipe pitch, failed air vents, waterlogged returns, and combustion issues specific to these units. We also know when a section is cracked beyond repair and replacement is the only safe option. Not every shop in metro Detroit will touch a 1920s boiler. We will. Call (866) 561-3358 to discuss your system.
