Denver's Go-To Furnace Repair Team

Furnace Repair in Denver is a category of heating service that diagnoses and fixes gas and electric furnaces when they stop heating, short cycle, or fail to ignite. Denver winters drop into the single digits, and a furnace that quits at 2 a.m. in Capitol Hill or Washington Park is not a wait-until-Monday problem. Our technicians live and work along the Front Range, so we know how Denver's older brick bungalows in Berkeley handle airflow differently than new builds out near Stapleton. We stock the flame sensors, igniters, capacitors, and control boards that fail most often on Denver systems, which means most repairs are finished in one trip. Whether you need a gas furnace repair, a high-efficiency furnace repair, or a full furnace replacement, we handle the whole job, pull the permits, and test the system before we leave. We answer the phone 24/7, give you a straight price before we start, and stand behind every repair with a written warranty.

Furnace Tune-Up

A fall tune-up in Denver catches problems before the first cold snap. We clean the flame sensor, check the igniter, test the gas valve, measure static pressure with a manometer, and inspect the heat exchanger. Most tune-ups take about an hour and can add years to your furnace's life.

View Details

Furnace Maintenance

Ongoing maintenance keeps Denver furnaces running through the long heating season. We replace air filters, check the blower motor, test the capacitor, and verify combustion with a combustion analyzer. We schedule maintenance visits around your calendar, and we remind you when the next one is due.

Gas Furnace Repair

Gas furnace problems in Denver often trace back to a dirty flame sensor, a failed igniter, or a gas valve that will not open. We test each component with a multimeter and clamp meter, confirm the fix, and check for gas leaks before we leave. Safety checks are part of every gas furnace repair.

View Details

Electric Furnace Repair

Electric furnaces in Denver fail differently than gas units. We test heating elements, sequencers, and the control board, and we check the breaker and wiring for the fault. If your electric furnace is tripping the breaker or blowing cold air, we can usually pinpoint the issue in one visit.

View Details

High-Efficiency Furnace Repair

High-efficiency condensing furnaces are common in newer Denver builds and can be fussy about drainage and airflow. We service the condensate system, check the secondary heat exchanger, and verify combustion with a combustion analyzer. These systems need a tech who knows them, and ours do.

View Details

Furnace Cleaning

Dust, pet hair, and Denver's dry air leave furnaces dirty by mid-winter. We clean the burners, blower compartment, and flame sensor, vacuum the heat exchanger, and replace the air filter. A clean furnace runs cooler, uses less gas, and lasts longer.

Furnace Replacement in Denver

If your furnace is aging, inefficient, or constantly breaking down, furnace replacement in Denver can restore comfort and cut energy costs. We specialize in replacing old systems in Denver's historic homes and modern apartments. Our team guides you through selection, installation, and disposal.

High-Efficiency Furnace Repair in Denver

High-efficiency furnaces save energy, but they need specialized care. Our high-efficiency furnace repair in Denver is performed by technicians trained on condensing technology. We understand the unique demands of these systems in Denver's altitude, including condensate management and PVC venting. Whether your unit is in a Denver high-rise or a suburban home, we restore its performance.

Condensate System Repairs

High-efficiency furnaces produce condensate, which can freeze in Denver's cold winters. We inspect drain lines, traps, and pumps for blockages or cracks. If your furnace shuts down due to a clogged drain, we clear it and prevent future issues. Proper condensate management is key to reliable operation.

PVC Venting Issues

These furnaces use PVC pipes for intake and exhaust. In Denver, snow can block vents, causing safety shutdowns. We check for proper slope, support, and termination clearances. If we find problems, we re-pipe the venting to code. This ensures safe, efficient operation year-round.

Advanced Diagnostics

We use manufacturer-specific diagnostic tools to read error codes and sensor data. This allows us to pinpoint issues like a failing inducer motor or a dirty flame sensor. Our high-efficiency furnace repair denver service includes a thorough combustion analysis to verify peak efficiency after repairs.

Furnace Cleaning in Denver

Dust, debris, and allergens accumulate in your furnace, reducing efficiency and air quality. Our furnace cleaning in Denver removes buildup from burners, blowers, and heat exchangers. We serve homes across Denver, from Globeville to University Hills, improving indoor air and system performance. Schedule a cleaning to breathe easier and save on energy bills.

01

Deep Cleaning Process

We begin by shutting off power and gas, then remove the burners and clean them individually. The blower motor is brushed and vacuumed, and the heat exchanger is inspected for cracks. We use HEPA vacuums to contain dust. This thorough furnace cleaning denver service leaves your system spotless.
02

Improving Indoor Air Quality

A dirty furnace circulates dust and allergens throughout your home. In Denver's dry climate, static electricity attracts more particles. After cleaning, we can also install high-quality filters or air purifiers. You'll notice less dust and fewer allergy symptoms. Cleaner air is healthier for everyone.
03

Efficiency and Longevity

A clean furnace runs more efficiently, using less gas or electricity to heat your home. It also experiences less wear on components like the blower motor. Regular cleaning can extend the life of your furnace by years. For Denver homeowners, it's a small investment with big returns.

Residential Furnace Repair in Denver

Most of our Denver work is residential. We fix furnaces in bungalows, Victorians, mid-century ranches, and new builds. Every home is different, and we treat it that way. If you have kids, pets, or an elderly family member in the house, a cold night is not just uncomfortable, it is a health risk. We prioritize those calls. We also know that Denver homeowners want straight answers, not a sales pitch. If your furnace can be fixed, we fix it. If it is time to replace, we tell you why and give you options.

Same-day furnace repair — We run same-day service across Denver for no-heat calls. Most repairs are done in one visit because we carry the parts that fail most often on Denver systems. If you call before noon, we can usually get to you the same day.
Furnace tune-ups and maintenance — A yearly tune-up keeps your Denver furnace running through the winter. We clean the flame sensor, check the igniter, test the gas valve, and inspect the heat exchanger. Tune-ups run $99 to $179 and take about an hour.
Furnace replacement — When your furnace is past saving, we replace it fast. We size the new unit with a proper load calculation, pull the permit, and install it in a day. We haul away the old furnace and test the new one before we leave.
High-efficiency furnace service — High-efficiency furnaces are common in newer Denver homes. They need a tech who understands condensate drainage and combustion. We test with a combustion analyzer and check the secondary heat exchanger on every service call.

Common Furnace Problems in Denver

Denver's climate and housing stock create a specific set of furnace problems. Here are the ones we see most often, and what causes them.

Dirty flame sensor causing no-heat calls

Denver's dry air and dust mean flame sensors get coated with carbon faster than in humid climates. A dirty sensor cannot detect the flame, so the furnace shuts off after a few seconds.

Cracked heat exchanger in older furnaces

Many Denver homes have furnaces that are 15 to 25 years old. Over time, the heat exchanger metal fatigues from repeated heating and cooling cycles. Denver's temperature swings speed up that process.

Short cycling from oversized furnaces

Some Denver homes have furnaces that were sized by square footage instead of a proper load calculation. An oversized furnace heats the house too fast, hits the limit switch, and shuts down. It cycles constantly and wears out fast.

Condensate drain freezing in high-efficiency furnaces

High-efficiency furnaces produce water as a byproduct of combustion. In Denver, that drain line can freeze if it runs through an unheated space like a crawlspace or garage. When it freezes, the furnace locks out.

Signs You Need Furnace Repair in Denver

Denver furnaces rarely fail without warning. Most give you a sign first, and catching it early can save you a cold night and a bigger repair bill. If you notice any of these, call us before the problem gets worse.

Furnace is blowing cold air

If the blower is running but the air is cold, the burners are not igniting. Common causes are a dirty flame sensor, a failed igniter, or a gas valve issue. This is urgent in winter because the furnace is running but not heating.
Furnace is short cycling

Short cycling means the furnace turns on and off every few minutes. It can be a thermostat problem, an oversized furnace, or a failing flame sensor. It wears out parts fast and raises your gas bill. Get it checked before it fails completely.
Banging or booming noise on startup

A loud boom when the furnace fires is often delayed ignition, which means gas is building up before it lights. That is a safety issue. Turn the furnace off and call us. It can also be a sign of a dirty burner or a failing gas valve.
Furnace is leaking water

High-efficiency furnaces produce condensate, and a clogged drain line can cause water to pool around the unit. On a standard furnace, a leak can mean a blocked flue or a failing humidifier. Either way, it needs attention before it damages the floor or the furnace.
Furnace is tripping the breaker

If your furnace keeps tripping the breaker, there is an electrical fault, a shorted motor, or a bad capacitor. Do not keep resetting the breaker. Call us and we will test the circuit with a clamp meter and find the fault.

Furnace Repair Costs in Denver

Typical 2026 pricing for furnace repair in Denver runs $180 to $450 for common fixes like a flame sensor, igniter, or capacitor replacement. Diagnostic visits are $89 to $129, and we waive that fee if you approve the repair. Emergency calls after hours run $50 to $100 more. A full furnace replacement in Denver usually costs $3,800 to $7,500 installed, depending on the size of your home and the efficiency of the new unit. High-efficiency condensing furnaces cost more upfront but can cut gas use by 15 to 25 percent. We give you a written price before we start, and we do not add charges after the fact. If you want a tune-up instead of a repair, those run $99 to $179 depending on the system.

Denver Furnace Repair by Season

Denver's seasons put different demands on your furnace. Here is what to expect and what to do each season.

Spring

Spring in Denver is unpredictable. You might run the furnace at night and the AC in the afternoon. That back-and-forth stresses the furnace and can cause short cycling. It is also a good time to catch problems before summer.

Tip: Schedule a spring tune-up if you skipped fall maintenance. We clean the flame sensor, check the igniter, and test the system so it is ready for next winter.

Summer

Your furnace sits idle in summer, which is actually a good time for maintenance. Dust settles on the burners, and small problems go unnoticed. Summer is also the best time to schedule a replacement because demand is low.

Tip: Book a furnace cleaning and inspection in summer. If your furnace is old, get a replacement quote now so you are not making a rushed decision in January.

Fall

Fall is when Denver furnaces get their first real workout. The first cold snap in October or November sends a wave of no-heat calls. Most of those calls are preventable with a fall tune-up.

Tip: Schedule your fall tune-up in September or early October. We clean the flame sensor, check the heat exchanger, and test the gas valve so your furnace is ready for the first freeze.

Winter

Winter is our busy season. Denver temperatures drop into the single digits, and furnaces run constantly. Igniters, flame sensors, and blower motors fail most often in winter. Emergency calls spike during cold snaps.

Tip: Change your air filter every month in winter. If your furnace is making noise or short cycling, call us before it fails completely. A small repair now beats an emergency call at 2 a.m.
