Why Northglenn Homeowners Choose Fireside Heating & Air Co.
We’ve been called to enough homes off Grant Drive and around E.B. Rains Jr. Memorial Park to know the Perl-Mack floor plans by heart. That matters when your furnace quits on a January night and the technician already knows your closet dimensions before he parks the truck.
Fireside Heating & Air Co. has served Northglenn homeowners since 2018. Our technicians are background-checked, uniformed journeymen who put on shoe covers without being asked. Every repair and installation is backed by our 90-Day Done Right Promise - written, no paperwork, no arguing. The price we quote is the price you pay.
We answer our own phones. Not a call center in another state. A live person, 24 hours a day, 7 days a week, including holidays. Northglenn residents in the original Perl-Mack sections near Melody Drive and the newer infill around Fox Run have both told us the same thing: they called because they were tired of voicemail trees and bait-and-switch pricing.
Our standing offers apply here: $50 off any repair over $250, a free second opinion on any written estimate, $89 seasonal tune-ups, and a permanent 5% discount for seniors and veterans. No games. A square deal.

Heating & Furnace Service
The 50-to-65-year-old homes that define Northglenn were built with furnace closets sized for 1960s equipment. Modern high-efficiency replacements often require cabinet relocation or wall modification before the HVAC work begins. We’ve done this dozens of times in the original Perl-Mack tracts.

Heat Pump & Mini Split Systems
Heat pumps work well in Northglenn’s relatively mild Front Range winters, but altitude derating is mandatory at 5,400 feet. We size and install systems that account for the thinner air, not formulas copied from sea-level manuals.

Original sheet-metal ductwork in Northglenn’s Perl-Mack homes leaks conditioned air into crawlspaces and draws in dust. We test, seal, and upgrade our Air Quality & Ventilation in Northglenn to match what modern filtration and humidity control require.

Why Northglenn’s Climate & Housing Affect HVAC
Northglenn sits at roughly 5,400 feet on the Front Range, and that altitude is not a footnote. Every gas furnace installed here must be derated for thinner air. The combustion process changes. Heat exchangers run hotter when the air-fuel ratio is off. We’ve found original installations in Northglenn where this step was skipped entirely, leading to cracked exchangers and carbon monoxide risks decades before their time.
The Chinook winds make it worse. A 40-degree temperature swing in six hours sounds like a weather curiosity until you realize your furnace ran full-bore at dawn and your air conditioner cycled three times by afternoon. That thermal whiplash destroys contactors, stresses reversing valves in heat pumps, and short-cycles equipment into early failure.
Then there’s the housing stock itself. Northglenn was built almost entirely between 1959 and 1975 by the Perl-Mack Companies, creating one of Colorado’s most uniform suburban communities. The result is a dense concentration of homes whose original forced-air systems, ductwork, and heat exchangers are all expiring together. Thornton, CO, just to the south, grew across multiple decades with far more varied housing. Northglenn’s replacement wave is concentrated and predictable in a way that shapes every service call we make here.
The Perl-Mack-era furnace closets near Melody Drive are a particular challenge. Built for 1960s gravity-style units, they’re often too shallow for modern 96% AFUE two-stage furnaces with their PVC combustion-air and exhaust requirements. We’ve relocated cabinets into adjacent laundry areas, punched exterior walls for direct venting, and reconfigured return-air plenums to make modern equipment fit safely and code-compliantly. What looks like a standard swap on the phone becomes a half-day carpentry job before the HVAC work starts. We quote that honestly upfront. The price quoted is the price paid.

Northglenn was built almost entirely between 1959 and 1975, so original furnaces, heat exchangers, and ductwork are all reaching end-of-life simultaneously. This concentrated replacement wave doesn’t happen in neighboring cities with more varied housing ages. If your home is in the original Perl-Mack tracts, we can usually estimate your system’s remaining life from the street address.
Yes. At 5,400 feet, gas furnaces must be derated for thinner air or the combustion mixture runs too rich, overheating heat exchangers and creating carbon monoxide risks. We’ve found older Northglenn installations where this was skipped, cutting equipment life by half. Any technician working here should verify derating on every gas-fired installation.
Most Northglenn AC repairs are completed same-day, with emergency calls typically reached within an hour. We stock common parts for Carrier, Trane, Bryant, and American Standard systems on every truck. Call (866) 561-3358 - a live person answers 24/7.
If your Northglenn home has the original Perl-Mack-era furnace and the heat exchanger is cracked or the repair exceeds 40% of replacement cost, we recommend replacement. Modern 96% AFUE units cut gas bills significantly, though compact closets may require modification. We’ll give you straight talk about repair versus replace and quote both options upfront. Call (866) 561-3358 for a free second opinion.

What Northglenn Customers Say
"Ductwork in the attic had a disconnected run dumping cold air into the insulation. He found it, resealed it, and a bedroom that was always hot is normal now."
- Hector Guzman"Two other companies told me I needed a whole new system. He put gauges on it, found a leak at a fitting on the line set, repaired and recharged it. That was over a year ago and it is still holding."
- Christine Kim"The thermostat had been miswired by whoever installed it, so the heat strips were running with the AC. He found it in a few minutes and probably saved me a fortune on the next few bills."
- Nicole Fletcher
