Fast, Reliable Emergency & Commercial HVAC Across Detroit
When your boiler quits at midnight in January or your rooftop unit fails before a Monday opening, you need someone who answers the phone and knows Detroit’s buildings. Fireside Heating & Air Co. has our Emergency & Commercial HVAC team standing by live, 24 hours a day, to take your call at (866) 561-3358. We understand the heating systems in Detroit’s pre-1950 brick bungalows and two-family flats because we’ve worked on them for decades, and we dispatch technicians who won’t waste your time guessing about one-pipe steam or cast-iron radiators.
From the Boston-Edison corridor down to Woodbridge and across to the riverfront, Detroit’s housing stock demands specific expertise. Lake-effect snow and hard freezes from November through March punish aging boiler systems. When a pressure relief valve fails or an expansion tank ruptures, you can’t wait for a suburban tech to figure out pipe pitch. We’re already familiar with the problem.
Why Fireside Heating & Air Co. Is Detroit’s Preferred Emergency & Commercial HVAC Company
We’ve served homeowners and business owners for over 8 years, and our reputation in older industrial cities like Detroit matters to us. Our 90-Day Done Right Promise means if we don’t get it right, we make it right - in writing, no paperwork, no arguing. That’s the Keystone Standard, and we apply it to every job, whether it’s a midnight emergency on Cass Avenue or a planned commercial inspection in the New Center area.
A live person answers every call, 24/7, including holidays. No voicemail tree. When you call (866) 561-3358 at 2 a.m. because your radiators are ice-cold and the temperature’s dropping, you’ll talk to someone who can dispatch help. Our background-checked, uniformed technicians put on shoe covers without being asked and treat your home the way they would their own mother’s.
We train our journeymen on nine major brands - Rheem, York, Daikin, Bryant, and others - and we stock parts to avoid leaving you waiting. Most jobs are completed in a single visit. Glen Hartman has built this company on straight talk and showing up when we say we will.
Our Emergency & Commercial HVAC Services in Detroit
24/7 Emergency HVAC
Boilers don’t fail on schedule. When a cast-iron section cracks after a hard freeze, or a scavenged copper line leaves your rehabbed flat without heat, you need same-day response. Our emergency line runs every night, weekend, and holiday. We carry common parts for Detroit’s aging systems, and our techs know how to diagnose one-pipe steam problems that stumped the last company you called. A square deal: the price quoted is the price paid, even at 3 a.m.
Commercial HVAC
Detroit’s commercial buildings - from renovated warehouse lofts to small retail on Gratiot or Grand River - run rooftop units, chillers, and split systems that can’t afford downtime. We service and inspect commercial equipment with the same upfront pricing and written guarantee we offer homeowners. If your building serves tenants or customers, we’ll prioritize getting you operational before business hours.
Rooftop Unit Service
Flat-roof commercial properties in Detroit’s older districts often depend on packaged rooftop units exposed to lake-effect snow and summer humidity. We perform full inspections, refrigerant checks, and component replacement on RTUs, with attention to the corrosion and seal degradation that Michigan weather accelerates. Annual maintenance catches problems before they become emergency calls.
Chiller Service
For larger commercial facilities with process cooling or central chilled-water systems, chiller failures can halt operations entirely. Our technicians diagnose compressor issues, refrigerant leaks, and control failures on commercial chillers, with parts sourcing that minimizes downtime for Detroit businesses.
HVAC Inspection
Before you buy a rehabbed bungalow in 48202 or inherit a two-family flat with an unknown heating history, get a full inspection. We document boiler condition, check for scavenged lines or missing radiators, and give you straight talk about repair versus replace. In Detroit’s market, this inspection often reveals whether you’re looking at a $400 vent replacement or a $15,000 full gut-conversion.
Annual Maintenance
Detroit’s sustained heating season and humid summers mean systems run hard most of the year. Our $89 Seasonal Tune-Up checks pressure relief valves, expansion tanks, burner operation, and safety controls. For one-pipe steam systems, we verify pipe pitch and air vent function - maintenance that prevents the water hammer and no-heat calls that spike during every cold snap.

Trusted Brands We Service in Detroit
We’re trained to service all nine major residential and commercial brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Detroit customers, this means we stock common parts locally rather than ordering from a warehouse three states away. When your 1920s system needs a modern replacement, we can spec and install Rheem or York equipment sized correctly for your building’s heat loss. Daikin and Bryant options work well for homes converting from radiator heat to forced air with ductless mini-splits or compact duct systems. Fast turnaround matters in a city where winter doesn’t wait.
Common Emergency & Commercial HVAC Problems We See in Detroit Homes
- Cracked cast-iron boilers after freeze events. When Detroit’s hard freezes hit vacant properties, waterlogged cast-iron sections crack beyond repair. We’ve replaced dozens of these in rehabbed flats where the boiler sat cold through multiple winters. Full system replacement is often the only option.
- Scavenged copper and missing radiators in rehabs. Contractors re-entering properties in neighborhoods like Woodbridge or the North End find stripped systems. Repair is impossible when the components are gone. We redesign from scratch, engineering forced-air conversions through existing wall cavities.
- Chronic water hammer from incorrect pipe pitch or failed Gorton air vents. One-pipe steam systems depend on precise slope and functioning air vents. When pitch settles or vents clog, steam collapses against condensate and hammers through pipes at 2 a.m. The fix is specific and technical, not a matter of bleeding radiators.
- Complete cooling absence in radiator-only homes. Detroit summers are humid and hot enough to demand AC. Homes built for coal heat never had ductwork, so central cooling requires engineered solutions - ductless mini-splits, high-velocity systems, or full gut-conversions. We size and install these correctly the first time.

FAQs - Emergency & Commercial HVAC in Detroit
Yes, we service and repair functioning one-pipe steam systems, including diagnosing pipe pitch problems, replacing failed Gorton air vents, and clearing waterlogged returns. These skills are increasingly rare outside Detroit’s city limits, where such systems were replaced generations ago. If your boiler is operational, we’ll keep it running honestly - and tell you straight when replacement makes more sense than throwing money at failing cast iron. Call (866) 561-3358 to schedule an inspection.
Yes, our emergency line operates 24 hours a day, 7 days a week, including all weekends and holidays, with a live person answering every call. We dispatch to Detroit neighborhoods from Woodbridge to Boston-Edison and throughout ZIPs 48201, 48202, 48231, and 48232. Winter weekends see our highest call volume, so early calling improves response time. Save (866) 561-3358 now.
It depends on condition and your long-term plans. If radiators and supply lines are intact, steam or hot-water heat is efficient and preserves historic character. If copper’s been stripped or the boiler’s cracked, forced-air conversion lets you add central AC in the same project - critical for Detroit’s humid summers. We inspect and give straight talk about repair versus replace, with real numbers for each path. Free estimates: (866) 561-3358.
Banging, or water hammer, happens when steam meets standing water in one-pipe systems, usually from settled pipe pitch or failed air vents that prevent proper condensate drainage. Detroit’s freeze-thaw cycles shift building foundations over decades, altering pipe slope. The fix involves re-pitching pipe sections and replacing Gorton or equivalent vents - not bleeding, which only works on two-pipe hot-water systems. We diagnose this correctly and stop the noise. Call for an appointment.
Yes, this is common work for us in Detroit. Options include high-velocity compact duct systems, traditional ductwork engineered through existing walls, or ductless Daikin or Bryant mini-split configurations. Each approach has different cost and disruption profiles. We assess your structure’s constraints and recommend what actually fits, not what we’d prefer to sell. Summer humidity here demands real cooling, not window units. Get a free evaluation at (866) 561-3358.
