Why Fireside Heating & Air Co. Is Rochester Hills’s Preferred Emergency & Commercial HVAC Company
We’ve worked in Rochester Hills long enough to recognize the house before we pull up. The 3,400 sq ft colonial with the original Carrier 80% furnace. The quad-level off Adams Road with the R-22 condenser that finally gave out in July. Our technicians have replaced heat exchangers, balanced ducts in multi-level homes, and pulled calcified humidifier pads from systems choked by Oakland County’s hard water. This isn’t theoretical knowledge - it’s repeated, hands-on experience with the exact housing stock that dominates 48307.
Our customers in Rochester Hills call us back because we quote upfront and stand behind the work. The 90-Day Done Right Promise means if something isn’t right, we make it right - in writing, no paperwork, no arguing. No voicemail trees, either. A live person answers our phones 24 hours a day, 7 days a week, including holidays. Background-checked, uniformed technicians arrive when we say they will, put on shoe covers without being asked, and treat your home the way they’d treat their mother’s.
Most jobs are completed in a single visit. We’ve been at this since 2018.
Our Emergency & Commercial HVAC Services in Rochester Hills
24/7 Emergency HVAC
Heating emergencies in Rochester Hills don’t wait for business hours, and neither do we. When that first November cold snap hits and half the subdivisions off Tienken Road fire up furnaces that haven’t run since April, our phones light up with no-heat calls. Often it’s a hairline crack in a secondary heat exchanger - accelerated by decades of hard-water scale from bypass humidifiers forcing the burner to overwork. We isolate the problem, verify safe operation, and get heat restored the same night. Emergency service runs $150-$700 depending on the repair, and we never charge overtime rates just because it’s 2 a.m.
Commercial HVAC
Rochester Hills businesses along Rochester Road and in the industrial parks near M-59 rely on consistent climate control for employees, customers, and equipment. We service packaged rooftop units, split systems, and dedicated outdoor air systems for offices, retail, restaurants, and light manufacturing. Our commercial customers get the same upfront pricing and 90-Day Done Right Promise as our residential accounts. We also coordinate after-hours service to minimize disruption to your operation.
Rooftop Unit Service
Flat-roof commercial buildings throughout Rochester Hills depend on rooftop units that take a beating from southeast Michigan’s freeze-thaw cycles and summer humidity. We handle everything from belt and bearing replacements to full refrigerant recovery and compressor swaps. Because we stock parts for major brands including York, Daikin, and Bryant, most Rochester Hills rooftop repairs don’t require a return trip.
Chiller Service
For larger commercial facilities in and around Rochester Hills with process cooling or high-tonnage comfort cooling, chiller reliability is non-negotiable. We diagnose refrigerant leaks, evaluate compressor performance, and assess heat exchanger efficiency on water-cooled and air-cooled chillers. Our approach is straightforward: tell you what’s actually wrong, what it costs to fix, and whether replacement makes more sense.
Annual Maintenance
In Rochester Hills, annual maintenance isn’t a luxury - it’s survival. The long heating season and hard water conditions mean furnaces work harder and longer than in milder climates. Our $89 Seasonal Tune-Up includes combustion analysis, heat exchanger inspection, humidifier pad evaluation, and condensate line clearing. For commercial accounts, we customize maintenance agreements around your equipment age, usage patterns, and occupancy schedule. Catching a cracked heat exchanger in October beats a CO alarm in November.
HVAC Inspection
Buying one of those 1980s or 1990s colonials? Selling and need a clean bill of health? Our HVAC inspections document equipment age, condition, safety concerns, and realistic remaining life. In Rochester Hills, we always check for bypass humidifier scale buildup, R-22 refrigerant status, and duct balancing issues that standard home inspectors miss.

Trusted Brands We Service in Rochester Hills
We’re trained and equipped to service nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Rochester Hills customers, this means we stock common parts locally and don’t waste days ordering components. Most late-1980s builds we see in 48307 originally carried Carrier or Lennox equipment, and we still service those systems daily - though we also help homeowners evaluate when replacement becomes the smarter play. We carry Rheem, York, Daikin, and Bryant equipment for new installations, selected for reliability in southeast Michigan’s dual-season climate.
Common Emergency & Commercial HVAC Problems We See in Rochester Hills Homes
- Cracked secondary heat exchangers in 80% furnaces. In subdivisions off Tienken Road and Adams Road built in the late 1980s, we regularly find original furnaces with hairline cracks - accelerated by decades of hard-water scale buildup inside bypass humidifiers that force the burner to overwork. CO spillage calls cluster in November when homeowners first fire up heat after summer.
- R-22 condenser failures with no viable recharge path. Original air conditioners from the 1980s and 1990s are well past design life, and R-22 refrigerant is phased out. When the evaporator coil leaks, replacement refrigerant is prohibitively expensive and retrofit options rarely make sense for these aging systems.
- Duct balancing failures in large multi-level homes. The 2,400-3,800 sq ft colonials and quad-levels common in Rochester Hills were rarely zoned properly from the factory. Manual dampers stick from years of disuse, and homeowners often misdiagnose hot second floors or cold basements as equipment failure when it’s actually a distribution problem.
- Calcified humidifier and condensate components. Oakland County’s limestone geology produces notoriously hard water. Humidifier media, condensate pumps, and drain lines calcify faster than regional averages, choking airflow and creating water damage risks that show up as “mystery” service calls.

FAQs - Emergency & Commercial HVAC in Rochester Hills
The majority of Rochester Hills homes were built between 1978 and 1998 with original 80% AFUE furnaces now aged 25 to 45 years - simultaneously hitting or exceeding design life across entire subdivisions. When the first sustained cold arrives, furnaces that ran without issue last season fail from thermal stress, cracked heat exchangers, or ignitor fatigue. In the subdivisions off Tienken Road, we see this pattern repeat every autumn. Schedule your $89 tune-up in September and beat the rush - or call (866) 561-3358 if you’re already cold.
Upgrading to a modern R-410A or R-32 system is almost always the better investment. R-22 is no longer manufactured, reclaimed supplies are expensive and dwindling, and retrofitting new refrigerant into old coils creates compatibility and efficiency problems. A new 16+ SEER system properly sized for your home’s square footage and duct capacity will cut cooling costs and qualify for available efficiency incentives. We offer free second opinions on any written estimate you’ve received - call (866) 561-3358 to compare.
Oakland County’s high-calcium water accelerates scale buildup in humidifiers, boilers, cooling towers, and condensate systems. In commercial settings, this means clogged spray nozzles, reduced heat transfer efficiency, and premature failure of water-regulated components. We address this through water-quality conversation on every service call - recommending filtration, treatment, or more frequent maintenance intervals based on your specific equipment and usage. Call (866) 561-3358 to schedule a commercial system evaluation.
A 2,400-3,800 sq ft colonial in Rochester Hills typically requires 80,000 to 120,000 BTU input, but proper sizing depends on insulation quality, window condition, duct leakage, and whether the basement is finished. We never guess. Our load calculations follow ACCA Manual J standards, accounting for southeast Michigan’s -5°F design heating temperature and your home’s specific construction. An oversized furnace cycles inefficiently and cracks heat exchangers faster; undersized equipment runs constantly and still can’t keep up. Call (866) 561-3358 for a proper sizing evaluation - estimates are free.
Yes. We customize maintenance agreements for Rochester Hills commercial customers based on equipment age, manufacturer specifications, and your operational priorities. Typical agreements include seasonal filter changes, belt and bearing inspection, refrigerant level verification, and combustion analysis where applicable. Preventive maintenance on rooftop units catches problems before they become weekend emergencies that disrupt your business. Call (866) 561-3358 to discuss a plan tailored to your facility.
