Aurora asks a lot of a home comfort system. Winter nights drop well below freezing and push older furnaces to their limit, while July heat waves punish air conditioners and the swamp coolers still sitting on so many north Aurora rooftops. When your heat or cooling fails here, it is not an inconvenience — it is a problem that needs a qualified local crew, fast.
PeakLine Heating & Air Aurora is an HVAC service company based at 595 Nucla Way in Aurora, CO 80011. We focus on the work Aurora homes actually need: furnace repair for the forced-air gas systems that heat most of the metro, AC repair and installation for homes upgrading past their old cooling equipment, and swamp cooler to central AC conversion — a specialty in neighborhoods where evaporative coolers have been limping along for decades.
Much of north Aurora's housing stock dates to the 1950s through the 1970s. Those homes are solid, but their mechanical systems are often original or decades old: aging furnaces with worn heat exchangers, undersized ductwork, and cooling equipment that was never designed for today's heat. We see the same patterns every week — furnaces that short-cycle, air conditioners that can't hold temperature on 95-degree days, and utility bills climbing because the system is working twice as hard as it should.
Our approach is straightforward. We diagnose the actual problem, explain it in plain language, and fix what needs fixing — repair first, replacement only when the math genuinely favors it. No pressure tactics, no mystery pricing, no disappearing after the invoice. Every visit starts with a real conversation about what your system is doing wrong.
We serve homeowners across Aurora and the surrounding north-metro communities, and our dispatch runs 24 hours for heating and cooling emergencies. Furnace out on a January night? AC dead during a heat wave? Call (303) 568-5036 and you'll reach someone who can get help moving — not a voicemail maze.
Whether it's a furnace tune-up before winter, a swamp cooler conversion you've been putting off, or a full system replacement, PeakLine Heating & Air Aurora is the local crew that shows up, does the work right, and stands behind it.
Twelve core services, one standard: diagnose honestly, repair properly, and explain everything before we touch a wrench.
Diagnosis and repair for gas furnaces that won't start, won't stay lit, blow cold air, or make noises they shouldn't. Serving Aurora's forced-air homes.
GET FURNACE HELP →Pre-season furnace maintenance: cleaning, safety checks, and performance testing so your system is ready before the first hard freeze hits Aurora.
BOOK A TUNE-UP →Full furnace replacement for systems past their prime — sized correctly for your home, installed clean, and hauled-away without the mess.
TALK REPLACEMENT →Air conditioner repair for units that won't cool, freeze up, leak, or drive up your electric bill. Fast diagnosis when the heat won't wait.
GET AC HELP →Central air installation matched to your home's size and ductwork — real cooling for Colorado summers, not an oversized guess.

Colorado homes live in two seasons. We keep you covered in both — with crews who know heating equipment and cooling equipment equally well.
When temperatures drop into the teens, your furnace is the most important machine in your house. We repair, tune, and replace gas furnaces — the forced-air systems that heat the vast majority of Aurora homes.
Whether your AC quit mid-July or your swamp cooler never really kept up, we bring real cooling to Aurora homes — repairs, new installs, and our signature swamp cooler conversions.
Find your symptom below. These are the patterns we see most in Aurora homes — the actual cause always needs a technician's eyes on the system.
Furnace runs but the house stays cold, or it won't fire up at all. Often a thermostat, ignition, or airflow issue — sometimes more.
AC blows warm or weak air on hot days. Could be refrigerant, electrical, a failed capacitor, or a dying compressor.
Banging, screeching, rattling, or humming from the furnace or AC. Noises are symptoms, not diagnoses — they deserve a look.
System dead at the thermostat. Power, control board, and safety-switch issues are common culprits worth checking first.
Furnace blows but the air never warms up. Heat exchanger, gas supply, and sensor problems all land on the suspect list.
Bills climbing with no change in habits? An aging or struggling system works harder for the same comfort.
Water around the furnace or AC needs attention — condensate lines, drain pans, and coils are the usual places to check.
System turns on and off every few minutes. It wears equipment fast and usually signals an underlying problem.
We're based in the 80011 — north Aurora, where the ranch homes went up in the 1950s, 60s, and 70s and a lot of the original heating equipment is still doing its best. Forced-air gas furnaces are the standard here, and plenty of houses still cool with rooftop swamp coolers that have seen better decades. We know these systems because we work on them every single day.
North Aurora neighborhoods like Morris Heights, Del Mar, and the streets around Chambers and Colfax share the same story: solid brick-and-frame homes with mechanical systems sized for a milder era. When a furnace from 1998 finally gives up on a January night, or a swamp cooler can't touch a 100-degree July afternoon, that's our call.
Being local means faster dispatch and honest context. We know which subdivisions have undersized ductwork, where the hard water eats through components faster, and which homes are prime candidates for a swamp cooler conversion versus a straightforward AC repair. That local pattern recognition saves you diagnostic time and money.
PeakLine Heating & Air Aurora operates from 595 Nucla Way in Aurora, CO 80011, and our trucks run across the city and the nearby north-metro suburbs. When you call (303) 568-5036, you're talking to a local dispatcher — not a national call center reading from a script.
PeakLine Heating & Air Aurora is based in Aurora and dispatches across the city and the surrounding north-metro suburbs. These are service areas — one local crew, one phone number.
The Denver north metro is a patchwork of housing eras, and each one stresses HVAC systems differently. Aurora's mid-century ranch homes run aging forced-air furnaces and, in many cases, original evaporative coolers. Head north to Thornton and Northglenn and you'll find 1970s–80s subdivisions where furnaces are hitting end-of-life in waves. Commerce City and Federal Heights mix older bungalows with newer infill, each with its own ductwork quirks.
South of us, Centennial and Greenwood Village lean toward larger homes with zoned systems and higher-efficiency equipment that needs technicians who actually understand staging and variable-speed controls. Parker keeps growing, which means newer systems — but also builder-grade installs that start showing their shortcuts within a few years.
Littleton and Englewood have some of the oldest housing stock in the metro, where we regularly find furnaces old enough to vote and ductwork that was an afterthought. Out east, Brighton and the eastern Denver neighborhoods blend rural-edge properties with suburban tracts. And Westminster sits in the middle of it all with a bit of everything.
What ties these communities together is climate: real winters that punish weak furnaces and summers hot enough to expose every weakness in a cooling system. PeakLine Heating & Air Aurora dispatches from our Aurora base across this entire arc — one crew, one standard of work, and a dispatcher who knows the area instead of a call queue that doesn't.
A Colorado furnace doesn't get sick days. When the temperature drops to single digits, yours needs to fire cleanly, heat evenly, and do it without filling your house with worry. Our pre-winter tune-ups catch the cracked ignitors, dirty flame sensors, and tired blower motors before they become midnight emergencies.
And when a furnace is truly done — heat exchanger shot, repair costs climbing past half the price of new — we'll tell you straight and size the replacement for your actual home, not a rule of thumb.
Get Winter-ReadyHalf of north Aurora still tries to beat July with a swamp cooler — a box of wet pads that gives up right when you need it most. Our signature move is converting those homes to real central air conditioning, tied into the ductwork your furnace already uses.
The result: 72 degrees on a 100-degree day, one tune-up a year instead of seasonal pad changes, and a system your home's value will thank you for. We also repair and replace conventional AC systems of every age.
Talk Cooling Options
A little attention goes a long way with heating and cooling equipment. Here's what actually helps — and when to stop and call a pro.
Listen to new noises. A furnace or AC that suddenly bangs, screeches, or rattles is telling you something changed. Note when it happens — that detail helps a technician diagnose faster.
Don't ignore water. Puddles around indoor equipment or a constantly running condensate line deserve a look before they become ceiling damage.
Stop resetting and restarting. If a system trips a breaker or lockout repeatedly, forcing it back on can turn a small electrical fault into a bigger one.
Check the obvious first. Thermostat set correctly? Breaker on? Filter changed in the last few months? These fix a surprising number of "emergencies."
Keep vents and returns clear. Furniture, rugs, and stored boxes blocking airflow make systems work harder and rooms heat unevenly.
Know your limits. Anything involving gas lines, high voltage, or refrigerant is technician territory. If basic troubleshooting doesn't resolve it, call (303) 568-5036.
Call (303) 568-5036 any time, or send the form below. A real dispatcher answers — day or night.
What the system is (or isn't) doing, when it started, and any noises or smells. The more you share, the faster we zero in.
A technician inspects the system, finds the actual cause, and explains your options with straight pricing — before any work begins.
We fix what's broken, test the full system, and leave the work area clean. You'll know exactly what was done and why.
