Fast, Reliable AC Repair & Installation Across Aurora
Most AC repair and installation calls in Aurora run $150-$650 for repairs and $3,500-$7,500 for full system installation, with same-day service available when you call (866) 561-3358. Our AC Repair & Installation team makes the drive from Denver to Aurora because this city’s split personality demands it: 1970s ranches with original ductwork in 80011 and brand-new subdivisions in 80016 where builder-grade systems are already failing. We’ve been answering live calls 24 hours a day for over 8 years, and we carry the inventory to fix both legacy retrofits and new installs in a single trip.
Aurora sits at 5,400 feet on Colorado’s semi-arid High Plains. That elevation matters. Out-of-town contractors routinely miscalculate furnace derating and AC sizing here, and homeowners pay for it with premature failures and rooms that never cool. We know the ZIP codes - 80012, 80013, 80014, 80015 - and we know what hides behind the walls in each one.
Why Fireside Heating & Air Co. Is Aurora’s Preferred AC Repair & Installation Company
We’ve served homeowners since 2018. That’s over 8 years of showing up when we say we will, quoting a price we stand behind, and backing every job with our 90-Day Done Right Promise in writing. No paperwork. No arguing. If it’s not right, we make it right.
Our phones are answered by a live person, 24 hours a day, 7 days a week - including the 2 a.m. call when your compressor seizes on a July night in eastern Aurora. Never a voicemail tree. Never “call back during business hours.”
Our technicians are background-checked, uniformed journeymen who put on shoe covers without being asked. They treat your home like their mother’s. And they carry parts for nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Most jobs are completed in one visit.
Aurora’s dual housing stock means a single service call can go from a 1970s ranch with undersized original ductwork in 80011 to a brand-new tract home in 80016 where the builder-grade AC was undersized from day one - a split that forces our techs to carry both retrofit and new-install expertise. That kind of range isn’t common in neighboring Centennial or even Denver proper. We’ve built our truck inventory and our training around it.
Our AC Repair & Installation Services in Aurora
AC Repair
When your AC quits in Aurora, you need someone who understands why it failed - not just someone who can swap a part. We responded to a 1974 ranch home near Buckley Air Force Base in 80011 where the homeowner had installed a new Trane AC unit, but only two rooms ever got cool. We found the original evaporative-cooler ductwork had never been resized for refrigerated air - supply trunks were too narrow and registers were in the wrong spots. We redesigned the duct layout, upsized the main trunk, and installed manual dampers to balance airflow. No more hot spots. Typical AC repair in Aurora runs $150-$650, and we offer $50 off any repair over $250.
AC Installation
New system installation in Aurora isn’t a matter of matching the old unit’s tonnage and calling it done. Western Aurora’s post-WWII and Vietnam-era ranch homes frequently have ductwork that was never engineered for refrigerated air - many were originally built with evaporative coolers. Installing a standard AC without first checking if the home’s original ductwork was sized for refrigerated air is a failure mode we see constantly. Our installations start with a proper load calculation, duct assessment, and elevation-adjusted sizing. Full AC installation in Aurora typically runs $3,500-$7,500, and every system is backed by our 90-Day Done Right Promise.
AC Replacement
Replacing a 1990s AC in eastern Aurora’s subdivisions requires verifying that the builder’s original system was properly matched to the home’s load. We’ve found undersized units in 80015 and 80016 that generated years of high callback volume as they aged into their first decade. We don’t quote like-for-like replacements. We measure, calculate, and specify a system that actually handles your home - not the one that was cheapest for the original builder.
Refrigerant Recharge & Compressor Repair
Low refrigerant and compressor failures spike during Aurora’s Chinook wind events, when temperature swings of 40°F or more within hours accelerate thermal stress. We carry R-410A and the gauges to find the leak, not just top off the charge. Compressor repair is often the difference between a $400 fix and a $6,000 replacement - we’ll give you straight talk about which path makes sense for your system’s age and condition.

Common AC Repair & Installation Problems We See in Aurora Homes
- Undersized ductwork from evaporative-cooler conversions. In 80010 and 80011, we routinely encounter 1960s-1970s homes that were converted from swamp coolers to refrigerated air in the 1980s or 1990s using ductwork that was never properly resized for AC static pressure. The original trunks are too small, supplies are in the wrong rooms, and homeowners get told they need a bigger AC when they actually need a duct redesign.
- Altitude-derating failures on gas furnaces. Aurora’s 5,400-foot elevation requires gas furnaces to be derated approximately 4% per 1,000 feet above sea level. Out-of-town contractors ignore this code requirement, leading to overheated heat exchangers and premature failure. We’ve replaced furnaces that failed in year eight because they were sized for sea level.
- Builder-grade undersizing in eastern subdivisions. The post-2000 and post-2010 tract homes in 80015-80019 often received minimally sized AC equipment installed at elevation. These systems generate high callback volume as they age into their first decade, with homeowners told repeatedly that “nothing’s wrong” while rooms stay warm.
- Chinook-driven compressor stress. Aurora’s rapid temperature swings - sometimes 40°F in hours - force thermal expansion and contraction cycles that stress solder joints, compressor valves, and electrical connections. We see compressor failures spike 48 hours after major Chinook events.

FAQs - AC Repair & Installation in Aurora
Hot spots after a new AC installation almost always point to ductwork that was never resized for refrigerated air - a chronic issue in western Aurora’s 1960s-1970s homes converted from evaporative coolers. The supply trunks are too narrow, registers are poorly placed, and static pressure is wrong for forced cooling. We measure airflow room by room and redesign the duct layout when needed. Call (866) 561-3358 for a free assessment - estimates are free.
Yes - AC systems must be elevation-adjusted for Aurora’s 5,400-foot elevation, and gas furnaces must be derated approximately 4% per 1,000 feet above sea level to prevent overheated heat exchangers. Out-of-market contractors routinely miss this. We size every system to Colorado’s High Plains conditions, not sea-level tables. Call (866) 561-3358 to verify your current system was sized correctly.
No - we strongly recommend against like-for-like replacement in eastern Aurora subdivisions. Many builder-grade systems in 80015 and 80016 were undersized from installation, and copying that tonnage locks in the same inadequate performance. We perform Manual J load calculations and verify duct capacity before specifying any replacement. Call (866) 561-3358 for a proper sizing evaluation.
Aurora’s Chinook wind events can swing temperatures 40°F or more within hours, creating extreme thermal stress on HVAC components and making your system work overtime to catch up. Properly sized equipment with adequate duct capacity handles these swings better than oversized or undersized systems. If your home can’t recover within 30 minutes of a Chinook shift, your system or ductwork is likely mismatched to your home. Call (866) 561-3358 and we’ll diagnose it.
Yes - with annual average humidity around 30%, Aurora’s semi-arid climate makes whole-house humidification a functional necessity for forced-air systems, not an upsell. Dry air cracks woodwork, irritates sinuses, and makes your home feel cooler than it is, causing you to set the thermostat lower. We integrate humidification into new installations where it makes sense for your home and budget. Call (866) 561-3358 to discuss options.
