We’re Fireside Heating & Air Co., and our Emergency & Commercial HVAC team has been getting homeowners and business owners back to comfortable since 2018. From the historic coal-miner cottages near Public Road to the sprawling subdivisions off US-287, we understand the specific systems, clearances, and code requirements that come with working in this town. Call (866) 561-3358 - a live person picks up, 24 hours a day, every day of the year.
Why Fireside Heating & Air Co. Is Lafayette’s Preferred Emergency & Commercial HVAC Company
Forty-two years in this trade teaches you that Lafayette is not a generic market. The same Chinook wind that warms a January afternoon to 50°F can snap it back to single digits by midnight, and those 40-60 degree swings crack heat exchangers in ways you rarely see on the eastern plains. We’ve replaced secondary heat exchangers in Coal Creek Ranch homes where the furnace ran three cycles before dawn because the thermostat couldn’t keep up with the temperature whiplash.
Our customers in Lafayette stay with us because we give straight answers about repair versus replace, and because our 90-Day Done Right Promise means the price quoted is the price paid - no paperwork, no arguing, just fixed. Background-checked, uniformed technicians. Shoe covers without being asked. A live voice on the phone at 2 a.m., not a voicemail tree. That’s the standard we’ve kept for over four decades.
We know the parking constraints around Simpson Street, the alley-load access behind older commercial buildings, and the Boulder County energy code requirements that are stricter than state minimums. When we quote equipment for a Lafayette job, we’re already accounting for the higher efficiency ratings Boulder County mandates. No surprises at permit time.
Our Emergency & Commercial HVAC Services in Lafayette
24/7 Emergency HVAC
Furnaces fail when it’s coldest. AC quits when it’s hottest. That’s the nature of the work. Our phones are answered by a live person around the clock - nights, weekends, holidays - and we dispatch to Lafayette with the parts and knowledge to fix most failures in a single visit. We carry common heat exchangers, ignition modules, and capacitors for the nine major brands we service, including Rheem, York, and Bryant units that are prevalent in the 1980s-2000s Lafayette build-out. When a Chinook swing cracks your secondary heat exchanger at midnight, we’ll be there.
Commercial HVAC
Lafayette’s commercial core has its own personality - mixed-use buildings along Public Road, light industrial near the railroad corridor, retail in Centaur Village and similar developments. Rooftop units, split systems, and packaged equipment all require different approaches, especially when access is through tight alleys or limited loading zones. We work around your business hours, quote upfront, and stand behind the work in writing. Our 90-Day Done Right Promise applies to commercial jobs too.
Rooftop Unit Service
Flat-roof commercial buildings in Lafayette’s commercial districts depend on rooftop units that take a beating from Front Range hail and high-altitude UV exposure. We service and replace RTUs from Daikin, Carrier, and other major manufacturers, handling crane logistics and curb adapters when the existing footprint doesn’t match modern equipment. Hail-damaged condenser coils are a recurring summer issue here - far more common than in eastern Colorado cities at the same latitude - and we stock replacement coils for faster turnaround.
Annual Maintenance
The $89 Seasonal Tune-Up pays for itself in Lafayette’s climate. We clean hail-debris from condenser fins, check heat exchanger integrity after a winter of thermal cycling, and verify that your system isn’t overworking due to undersized ductwork - a common finding in post-1980 slab homes along US-287 where builders sized to minimum code. Catching a cracked secondary heat exchanger in fall beats finding it at 10°F in January.

Trusted Brands We Service in Lafayette
We train our technicians as journeymen on nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Lafayette customers, this means we stock common parts locally rather than ordering from a warehouse two days away. Rheem and York furnaces appear frequently in the Coal Creek Ranch and Centaur Village subdivisions. Daikin mini-splits have become our go-to for historic cottages with no ductwork. Bryant systems are common in 1990s builds now hitting their replacement window. When you call, we likely have what you need on the truck.
Common Emergency & Commercial HVAC Problems We See in Lafayette Homes
- Cracked secondary heat exchangers in 30-to-40-year-old furnaces. The Chinook wind corridor subjects Lafayette to brutal thermal cycling. A furnace that fires six times on a swing day stresses its heat exchanger far beyond what steady-cold climates demand. We see this constantly in Coal Creek Ranch and similar 1980s-1990s subdivisions where original equipment is still running.
- Hail-damaged condenser coils. Lafayette sits in Colorado’s Front Range hail belt. Summer storms dent fins, bend tubing, and clog outdoor units with debris. Coil replacement or full AC installation is often the only fix, and it’s more common here than in Denver’s eastern suburbs at the same latitude.
- Undersized duct systems causing compressor failure. Post-1980 homes along US-287 were built to code-minimum duct sizing. When homeowners upsize equipment at replacement without remediating ducts, the airflow restriction burns out compressors prematurely. We measure static pressure and duct capacity before recommending any equipment change.
- No-heat emergencies in historic cottages with wall furnaces. The 1920s coal-miner cottages near Simpson Street and Public Road often have no ductwork at all. When the original wall furnace or converted gravity floor-furnace fails, it’s an emergency with no easy replacement path. Mini-split installation, routed through low crawl spaces, is frequently the only practical solution.

FAQs - Emergency & Commercial HVAC in Lafayette
Mini-split heat pumps are the practical default for pre-1930 coal-miner cottages with no existing ductwork. Full duct retrofits in these 900-1,100 sq ft homes are often cost-prohibitive and require tearing into historic structure. We route line sets through low crawl spaces or along exterior walls, giving you zoned heating and cooling without compromising the building’s character. Call (866) 561-3358 and we’ll assess your specific layout - estimates are free.
Your equipment is 30-40 years old, which is past design life for most residential HVAC. The added stress of Lafayette’s Chinook wind temperature swings - 40-60°F in a single day - thermally cycles heat exchangers and accelerates cracking in secondary exchangers. Original AC condensers also face annual hail exposure in the Front Range hail belt. Replacement with properly sized, Boulder County code-compliant equipment is usually more economical than repeated emergency repairs. We offer $50 off any repair over $250, and a free second opinion on any written estimate you’ve already received.
Call (866) 561-3358 - a live person answers 24/7, including holidays. Describe your access situation when you call. Our technicians carry compact equipment and are experienced with Lafayette’s older neighborhoods where alley access, narrow driveways, and limited parking are standard constraints. We’ll coordinate arrival details to avoid blocking traffic on Simpson Street or Public Road, and we stock the parts most likely to fail in local systems.
AC repair in Lafayette typically runs $150-$650 depending on the failure, while full AC installation ranges $3,500-$7,500. Boulder County’s stricter energy code requires higher minimum efficiency ratings than Adams or Douglas County, which can push replacement costs toward the upper end of that range. Hail damage sometimes reveals additional issues once we inspect. We’ll give you an exact quote after diagnosis - no obligation, no pressure. Seniors and veterans receive 5% off, always.
