Our Heat Pump & Mini Split crews have worked Southglenn’s 1960s-1980s housing stock long enough to spot the pattern: original forced-air systems retrofitted with central AC, ducts never resized, coils oversized, and equipment cycling itself to death. Glen Hartman started Fireside Heating & Air Co. back in 1984, and we’ve been sorting out these exact problems ever since. The long service drives on acreage properties west of Broadway don’t slow us down. Neither do the detached workshops with heavy overhead doors that Southglenn homeowners want conditioned year-round.
Why Fireside Heating & Air Co. Is Southglenn’s Preferred Heat Pump & Mini Split Company
We’ve served this corridor of Arapahoe County for over 8 years. That means we’ve replaced heat pumps in the original Southglenn Mall-era subdivisions, serviced mini splits in workshop outbuildings off Dry Creek Road, and traced airflow problems through crawlspaces that haven’t been opened since the Ford administration. Our technicians are trained journeymen, background-checked and uniformed, and they put on shoe covers without being asked.
Our 90-Day Done Right Promise applies to every job in 80122: if it’s not done right, we make it right, in writing, no paperwork, no arguing. Phones are answered by a live person 24 hours a day, 7 days a week, including holidays. The price we quote is the price you pay. We’ve built our reputation on being the company Southglenn homeowners call after the low bid lets them down.
Most repairs are completed in one visit because our trucks carry parts for Carrier, Trane, Bryant, and American Standard systems - the brands we see most often in this area. We don’t disappear for days waiting on a coil or a board.
Our Heat Pump & Mini Split Services in Southglenn
Heat Pump Installation
New heat pump installation in Southglenn demands more than equipment selection. At 5,500-5,800 feet elevation, every unit must be altitude-derated from its sea-level capacity rating. Out-of-area contractors skip this step with alarming regularity, leaving you with a system that underperforms and over-amps from day one. We size for your actual heat loss at elevation, account for the Chinook wind swings that stress cycling equipment, and verify that your existing ductwork can move the air the new system needs. For acreage properties with detached workshops, we install heavy-duty outdoor units positioned to avoid exhaust recirculation from oversized doors.
Heat Pump Repair
AC Repair & Installation in Southglenn - our work on 1980s retrofits revealed a generation of misdiagnosed “refrigerant leaks.” The real culprit is usually an evaporator coil oversized for ductwork that was never enlarged. We test static pressure, measure airflow at each register, and trace the problem to its source rather than pumping in refrigerant that leaks out again in six months. Our $150-$650 repair range covers everything from defrost board replacement to compressor diagnostics, and we apply a $50 discount to any repair over $250.
Mini Split Install
Ductless mini splits solve what ductwork cannot. In Southglenn’s split-level homes with finished basements and hot second floors, a multi-zone system lets you condition each level independently without tearing open walls to add returns. We mount slim indoor units on interior walls, run line sets through crawlspaces or soffits, and place the outdoor unit where it won’t fight for air against a workshop door. Single-zone systems for detached outbuildings are a specialty - we size for the load, not the square footage on a chart.
Mini Split Repair
Daikin, Carrier, and other mini split brands share common failure modes: clogged condensate pumps in dry, dusty Southglenn conditions; failed inverter boards from voltage fluctuation during Front Range storms; and refrigerant leaks at flare connections that weren’t torqued properly on the original install. We pressure-test with nitrogen, verify superheat and subcooling at altitude, and stand behind the repair for 90 days.
Ductless System & Multi-Zone System
Whole-home ductless replaces the compromised central system entirely. In the older Southglenn neighborhoods where trunk-and-branch duct systems feature undersized returns and minimal crawlspace insulation, going ductless eliminates the pressure problems that have made summers unbearable upstairs. Multi-zone configurations let you heat the main level during the day and drop the bedroom zones at night, cutting runtime hours without cutting comfort.

Trusted Brands We Service in Southglenn
We stock parts and service nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Southglenn customers, that means faster turnaround when your Bryant heat pump throws a code in January or your American Standard compressor won’t start before a Chinook wind drops the temperature forty degrees by dinner. We don’t have to order from Denver and make you wait. Our trucks carry the common boards, sensors, and contactors for these systems because we’ve learned what fails in this elevation and this climate.
Common Heat Pump & Mini Split Problems We See in Southglenn Homes
- Icing evaporator coils from duct mismatch. In the neighborhoods near the Streets at SouthGlenn, we regularly find 3-ton coils paired with 2-ton duct capacity. The system ices up, gets recharged, and ices up again. The fix is duct remediation, not more refrigerant.
- Altitude underperformance from skipped derating. Heat pumps installed by contractors unfamiliar with Front Range elevation run at sea-level capacity. The compressor works harder, draws more amps, and fails early. We see this on rural properties with long driveways where out-of-area companies bid low and install fast.
- Outdoor unit starvation near workshop doors. On acreage lots, heat pumps placed too close to oversized overhead doors recirculate exhaust air and lose capacity. We relocate or specify units with higher static tolerance for these installations.
- Chronic low humidity and static pressure. Southglenn’s semi-arid winter climate drops indoor relative humidity below 20 percent with forced-air heat running. Heat pumps running in defrost mode make this worse. We evaluate whether a whole-home bypass or powered humidifier belongs in the system design.

FAQs - Heat Pump & Mini Split in Southglenn
Your coil is almost certainly oversized for your ductwork, not low on refrigerant. In Southglenn’s 1980s retrofits, contractors frequently installed larger evaporator coils without enlarging returns or trunk lines, causing the coil to run below freezing and ice over. The refrigerant you added leaked past the TXV or backed up in the accumulator because the real problem is airflow, not charge. Call (866) 561-3358 for a free airflow assessment - we’ll measure static pressure and tell you whether duct remediation solves it.
Sometimes, but only after we test it. Many 1975 Southglenn ranches have original trunk-and-branch duct systems with 14-inch returns and uninsulated crawlspace runs that cannot handle the airflow a modern heat pump requires. We perform a Manual D calculation at altitude and tell you straight whether the ducts can stay, need modification, or should be bypassed with a ductless system. Call for a free evaluation.
Chinook events can swing Southglenn’s temperature 50 degrees in under twelve hours, forcing your Heating & Furnace in Southglenn or heat pump to switch between heating and cooling modes rapidly. This hard cycling accelerates compressor wear and confuses standard defrost controls. We specify heat pumps with extended temperature ranges and smart defrost logic for Front Range installations. If your current system struggles during wind events, it may be undersized or improperly derated for elevation.
Yes, and we size them for the actual load, including air infiltration around heavy doors and the heat loss from concrete slabs. We position the outdoor unit where it won’t ingest exhaust from vehicles or recirculate air trapped against the building. Ductless mini splits are ideal for Southglenn workshops because they heat and cool without running ducts from the main house. Call (866) 561-3358 to discuss your building.
Absolutely, and any contractor who says otherwise is not qualified to work at 5,500 feet. Heat pumps lose approximately 4 percent capacity per 1,000 feet above sea level. A 3-ton unit rated at sea level performs like a 2.5-ton unit in Southglenn. We derate every installation and size accordingly, which is why our systems don’t struggle on the coldest January nights. We also verify that the electrical service can handle the corrected amp draw. This is standard on every Fireside install - no extra charge, no option to skip it.
