Furnace repair in Las Vegas typically costs between $150 and $700, and most jobs can be scheduled same-day or next-day. The biggest variable isn’t the furnace itself, it’s what the house around it was built with. In older Las Vegas neighborhoods, original low-profile ductwork and outdated electrical panels turn what should be a simple ignitor swap into a system-wide correction. If your furnace is short-cycling, tripping the limit switch, or running but not heating, call Cold Harbour Heating and Air Las Vegas at (725) 726-3813. We answer the phone with a live person, give you a written price before work starts, and back every repair for 365 days.
Why Cold Harbour Heating and Air Las Vegas Is Las Vegas’s Preferred Furnace Repair Company
Victor Mancini, who leads our Las Vegas team, has seen just about every furnace failure the Mojave can produce. We’re not a franchise with a call center in another state. Dispatch and scheduling are coordinated from our Las Vegas office, and the technician who shows up at your door is background-checked, uniformed, and trained to service nine major residential brands including Carrier, Trane, Lennox, and American Standard.
Las Vegas homeowners call us because we put the Kingswell Way in writing. Every repair gets a written guarantee, valid for a full 365 days. If the repair fails inside that window, we come back and fix it at no charge. That’s not a verbal promise, it’s on paper before we leave. We also hand you a written price before a single tool comes out, and that price does not change at the door. Founded in 2003 as part of the Kingswell network of independently owned and operated HVAC businesses, we hold ourselves to five written values: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, and come back if it fails.
When your furnace quits in January and the overnight low near Summerlin or Anthem drops into the 30s, you don’t want to leave a voicemail and hope. Our Furnace Repair team answers live, 24 hours a day, 7 days a week. No phone trees. No after-hours runaround.
Styles & brands we work with
Furnace Maintenance in Las Vegas
Furnace Maintenance in Las Vegas is a flat-priced annual service that runs $80 – $200 and takes about an hour. Because Las Vegas sees over 100 days above 100°F, your furnace sits idle for months at a time, then suddenly fires up on the first cold night. Dust from monsoon season settles into the blower wheel, the burner assembly, and the flame sensor. When that dust burns off on the first call for heat, it can trip the flame sensor and shut the furnace down exactly when you need it. A tune-up before the cold snap prevents most of these first-start failures.
What We Check
We verify flame sensor voltage, test the ignitor, clean the blower wheel and motor, check static pressure across the duct system, and inspect the heat exchanger for cracks. The technician writes down what was found and gives you that report. Our technicians are not paid on what they sell, so the maintenance report you get reflects what the furnace actually needs.
When Las Vegas Homeowners Schedule
Most Las Vegas homeowners schedule furnace maintenance in October or November, before the first sustained cold snap. The desert can drop into the 30s at night from November through February, and furnaces that haven’t run since March often fail on their first startup. If you wait until the furnace won’t light, you’re paying repair rates instead of the $80 – $200 maintenance price.
Heat Pump Repair in Las Vegas
Heat Pump Repair in Las Vegas typically runs $150 – $650, and the job usually involves the reversing valve, the defrost control board, or a refrigerant leak at a brazed joint. Many Las Vegas homes built in the 1980s and 1990s use heat pumps for both heating and cooling, which means the system runs almost year-round. That constant runtime wears out the reversing valve faster than the rest of the system, especially during the shoulder seasons when the heat pump switches between heating and cooling modes multiple times per day.
Cold Snaps and Defrost Cycles
When Las Vegas drops below 40°F, the outdoor coil on a heat pump starts to frost over. The defrost board is supposed to reverse the refrigerant flow and melt that ice every 30 to 90 minutes. If the defrost thermostat or board fails, the coil ices up solid, the compressor strains, and the system locks out. We see this most often in central Las Vegas neighborhoods and along Boulder Highway, where heat pumps from the 1990s are still in service. A failed defrost board is a $150 – $400 repair, far less than a compressor replacement.
Trusted Brands We Service in Las Vegas
Cold Harbour Heating and Air Las Vegas services Bryant, American Standard, Carrier, Trane, and five other major residential brands. That matters when your furnace uses a brand-specific ignitor or gas valve. We keep common parts stocked locally for Las Vegas customers, so a failed ignitor on a Carrier furnace in Henderson or a Trane gas valve near Nellis AFB doesn’t have to wait on a parts shipment. Our technicians train on all nine brands and follow the same repair procedures whether it’s a 15-year-old Goodman or a newer American Standard.

Common Furnace Repair Problems We See in Las Vegas Homes
- Original low-profile ductwork from the swamp cooler era. Homes built in the 1960s and 1970s with roof-mounted swamp coolers often kept the original low-profile ducts when a central furnace was added later. The ducts are too restrictive for modern blowers, causing high static pressure, overheating limit switches, and cracked heat exchangers on cold desert nights.
- Outdated 60-amp electrical panels. Many older Las Vegas homes still run a 60-amp main panel. A modern furnace’s variable-speed blower and control board can pull enough current to trip breakers and cause failed ignition, especially when electric heat strips run at the same time.
- Single-zone systems in split-level homes. Older split-level homes in east Las Vegas often have one zone for two floors, creating a 10 – 15 degree temperature swing. The furnace short-cycles trying to satisfy the thermostat, which stresses the capacitor and blower motor while the downstairs stays cold.
- Monsoon dust clogging the filter and burner assembly. Dust storms from June through September leave fine silt inside the furnace cabinet. When the furnace fires up in November, that dust burns off the burner and coats the flame sensor, causing repeated ignition failures.

AfterPricing for Furnace Repair in Las Vegas, NV
Most furnace repairs in Las Vegas run $150 – $700, parts and labor included. Here’s the honest breakdown:
| Service | Typical Range |
|---|---|
| Furnace Repair | $150 – $700 |
| Furnace Maintenance | $80 – $200 |

FAQs About Furnace Repair in Las Vegas
Short-cycling in Las Vegas homes is usually caused by an oversized furnace or high static pressure from undersized ductwork, not by the cold itself. When the furnace is too large for the home’s heat load, or when original low-profile ducts restrict airflow, the furnace overheats quickly and the limit switch shuts it down before the house warms up. In older east-side and central Las Vegas homes, we regularly see static pressure readings above 0.9 inches water column, which will trip a limit switch every time the furnace runs long enough. The fix often involves more than a part: it requires measuring the duct system and correcting the airflow. Call (725) 726-3813 for a diagnostic visit.
In most cases, no. The low-profile ductwork installed for 1960s-70s swamp coolers was sized for evaporative cooling, not the airflow demands of a modern furnace blower. When you connect a new high-efficiency furnace to those old ducts, the blower pushes against too much resistance, static pressure climbs, and the furnace overheats or the heat exchanger cracks. We’ve corrected this exact problem in homes near Boulder Highway and Flamingo, where a 1970s ranch still had its original swamp cooler ducts. The solution is usually a larger return grille, a bigger filter cabinet, and an upsized main return run, sometimes with a proper load calculation before committing to a new furnace. Call us for an airflow assessment before you buy.
Yes, and it’s one of the most common Las Vegas-specific causes of repair calls. Monsoon season, from June through September, fills the furnace cabinet with fine dust that settles on the burner, blower wheel, and flame sensor. When the furnace fires up on the first cold night in November, that dust burns off and coats the flame sensor, causing ignition failures. If the filter wasn’t changed before the heating season started, the blower motor strains against a restricted filter and can overheat. A furnace maintenance visit before the cold snap, at $80 – $200, clears the dust and prevents most of these first-start failures.
Not safely, not without addressing the panel first. A 60-amp main panel from the 1960s or 1970s was sized for a house with far fewer electrical loads than a modern Las Vegas home. A variable-speed blower and its control board pull enough current that a 60-amp panel can trip breakers or fail to deliver clean voltage, which leads to failed ignition and short cycling. In many older Las Vegas homes, the corrective work is to either install a smaller furnace with a constant-torque motor, or upgrade the panel to at least 100 – 200 amps before upsizing the furnace. We’ll tell you which path makes sense for your house, and we’ll give you a written price before any work begins. Call (725) 726-3813 for an assessment.
Heat exchanger cracks in Las Vegas are almost always caused by airflow starvation, not by hard winter use. When a furnace runs with high static pressure from undersized ductwork, the heat exchanger gets hotter than it was designed to. That repeated overheating, combined with thermal cycling from the desert’s extreme temperature swings, causes metal fatigue and cracking. The furnace doesn’t need a brutal winter to crack the exchanger, it just needs to run long enough while over-restricted. If you smell a musty odor when the heat kicks on, or you see soot near the burners, have it checked immediately. A cracked heat exchanger is a carbon monoxide risk, and it’s a repair that should always be handled by a trained professional. Call us at (725) 726-3813.
