We’ve been serving homeowners since 2018, and Northglenn’s unique housing stock keeps us busy. The city was built almost entirely between 1959 and 1975 as one of Colorado’s first large-scale planned suburban communities, producing a dense concentration of 50-to-65-year-old homes whose original forced-air systems are all failing at roughly the same time. That replacement wave defines the local HVAC market in a way you won’t find in neighboring Thornton, which grew across multiple decades with far more varied stock. Our AC Repair & Installation team knows these homes inside and out - the tight furnace closets, the original sheet-metal ductwork, the slab-on-grade construction that limits your options. We don’t guess. We measure, we look at what’s actually there, and we tell you what it will take.

Our AC Repair & Installation Services in Northglenn
AC Repair
Most AC repair calls in Northglenn involve capacitors, contactors, or refrigerant leaks - failures accelerated by rapid temperature swings and decades of wear on original equipment. A typical repair runs $150-$650. We diagnose before we quote, and the price we give is the price you pay. No fine print. If your system is 8+ years old, we’ll give you straight talk about repair versus replace so you don’t throw good money after bad.
AC Installation
New AC installation in Northglenn starts around $3,500 and ranges up to $7,500 for full high-efficiency systems. But here’s what generic guides won’t tell you: in Perl-Mack-era homes around Melody Drive, the original furnace closets are so tight that installing a modern 96% AFUE furnace with PVC venting often requires relocating the cabinet or cutting an exterior wall before the AC work can even start. We recently worked on a classic split-level off Melody Drive. The homeowner’s original 1960s Carrier unit had finally failed with a seized compressor - a Heron-Anderson model long out of production. Because the furnace closet was only 30 inches wide, we had to frame out a new chase for PVC combustion air and exhaust before we could fit a two-stage high-efficiency furnace and matching 16-SEER AC condenser. The entire job, including the retrofit carpentry, came in around $5,200 for the full system replacement. We measure first, quote second, and stand behind the number.
AC Replacement
Replacement is where Northglenn’s uniform housing stock hits hardest. Original 1960s sheet-metal ductwork in these slab-on-grade homes often has asbestos wrap or undersized returns that choke modern high-efficiency AC systems, causing insufficient airflow and frozen coils. Furnace closets built for compact 1960s gravity-style units leave no room for modern equipment with PVC venting. We assess the full system - not just the box outside - so your new AC actually performs to its rating. Our $89 Seasonal Tune-Up can catch these issues before you’re forced into an emergency replacement.
Compressor Repair
Compressor repair in Northglenn runs $400-$1,200, depending on whether it’s a simple electrical fix or a full replacement. Rapid Chinook wind events cycle compressors hard, accelerating wear on reversing valves and capacitors. In aging systems, this leads to mid-season failures when you need cooling most. We’ll test the full refrigerant circuit and electrical stack before recommending repair or replacement - no point fixing a compressor if your original ductwork will starve it of airflow.
Refrigerant Recharge
Low refrigerant means a leak, period. In Northglenn’s older systems, leaks often develop at the evaporator coil or line sets buried in slab construction. We locate the leak, quote the repair, and recharge to factory spec. If your system still runs R-22, we’ll give you honest numbers on repair versus upgrading to modern R-410A equipment.

Trusted Brands We Service in Northglenn
We carry parts and stock common components for Carrier, Trane, Lennox, and the other major brands we service. For Northglenn’s older homes still running vintage equipment, this matters - we can’t always get a 1960s Heron-Anderson compressor, but we can usually source compatible modern replacements and adapt the mounting and electrical without a full system redesign. Fast turnaround keeps most jobs to a single visit. If your brand isn’t on our truck today, we’ll have it tomorrow.
Common AC Repair & Installation Problems We See in Northglenn Homes
- Original sheet-metal ductwork choking modern systems. The 1960s asbestos-wrapped or undersized returns common in Northglenn’s slab-on-grade ranches can’t move enough air for high-efficiency AC. Homeowners install a new 16-SEER unit and wonder why it freezes up. We check static pressure before we quote any installation.
- Furnace closets too tight for modern equipment. The Perl-Mack homes near Melody Drive were built with 30-inch cabinets for gravity-style furnaces. A modern 96% AFUE unit with PVC intake and exhaust simply won’t fit. We tell you upfront if carpentry is needed, and we build it into the quote.
- Chinook wind cycling destroying compressors. Those 40°F temperature swings in hours force your AC to start, stop, start again. Contactors pit. Capacitors fail. Reversing valves leak. It’s not bad luck - it’s physics, and it’s worse on 20-year-old equipment.
- Altitude derating skipped on old installs. Northglenn sits at 5,400 feet. Gas furnaces must be derated for altitude, a step frequently missed by previous installers. The result is chronic heat exchanger stress, which affects your whole system’s performance and safety. We check this on every service call.

FAQs - AC Repair & Installation in Northglenn
The original furnace closets in these Perl-Mack-built ranches are only about 30 inches wide, sized for 1960s gravity-style furnaces. A modern 96% AFUE unit requires PVC combustion air and exhaust pipes that simply won’t fit. We routinely frame out new chases or cut exterior walls to accommodate proper venting before the HVAC equipment goes in. This adds half a day of carpentry to what looks like a straightforward swap. Call (866) 561-3358 and we’ll measure your closet during the free estimate.
Usually, yes. Original sheet-metal ductwork in these homes has undersized returns and often asbestos wrap that restricts airflow below what modern high-efficiency systems need. Without adequate airflow, your new AC will struggle, cycle improperly, and eventually freeze the coil. We test static pressure during every installation quote and tell you exactly what your ductwork needs. Call (866) 561-3358 for a free assessment.
No. Heron-Anderson compressors have been out of production for decades, and no compatible replacement parts exist. We’ve encountered this exact failure on Melody Drive - the only path is a modern compressor swap or full system replacement, often requiring cabinet modifications for the new equipment’s dimensions. We won’t charge you to chase a part that doesn’t exist. Call (866) 561-3358 and we’ll quote your real options.
Chinook winds can swing outdoor temperatures 40°F within hours, forcing your AC to start and stop repeatedly. This hard cycling pits contactors, degrades capacitors, and wears reversing valves prematurely. It’s worse on aging equipment with already-weakened components. Regular maintenance catches this wear before it becomes a mid-season failure. Our $89 Seasonal Tune-Up includes electrical testing and contactor inspection.
For the gas furnace paired with your AC system, yes. Northglenn’s 5,400-foot elevation requires mandatory altitude derating on gas furnaces to prevent chronic heat exchanger stress and early failure. Many older installations skipped this step, which is why we see so many cracked heat exchangers in local homes. We verify derating on every installation and service call. It’s not optional - it’s code, and it’s safety.
