Las Vegas HVAC
Repairmen, Not Salesmen.
Las Vegas HVAC for the season nobody plans for. The nights have turned and the furnace has not run since March. We handle heating repair, replacement, and pre-season inspections across the valley — and we will tell you when your system has years left rather than selling you one you do not need.
Winter Is The Season Las Vegas HVAC Companies Forget
Ten months a year, nobody in this valley thinks about their heater. Then the first genuinely cold night arrives in November, the thermostat gets turned up, and a system that has sat untouched since March is asked to work perfectly on demand.
That is why the overwhelming majority of first-cold-snap failures we attend are not worn-out equipment. They are equipment nobody has cleaned since the last time it was needed — fine desert dust settled on the burners, the flame sensor, and the blower wheel across an entire summer of sitting still.
Mr. Gates Heating & Cooling is a family-owned Las Vegas HVAC company covering heating and air conditioning across Las Vegas, Henderson, North Las Vegas, and the surrounding valley. Gas furnaces, electric furnaces, heat pumps, and the rooftop package units that sit on a large share of homes in the valley — whatever brand is on the unit.
Our technicians are not paid commission on equipment. That single fact removes the incentive behind most of what has given this trade its reputation, and it is why the answer you get is the same one we would give our own family.
Heating Services
What Las Vegas HVAC customers actually need between November and February. Each service has its own page with the detail, the approach to pricing, and the questions homeowners really ask.
Furnace & Heater Repair
No heat, cold air at the vents, short cycling, or a system that will not start. We diagnose the actual fault before quoting anything.
Furnace Installation & Replacement
End-of-life systems replaced and sized to your actual home rather than copied off the old nameplate. Free estimates and a 10-year manufacturer parts warranty.
Heating Inspections
The autumn service that finds the failure before the cold snap does — and keeps your manufacturer parts warranty valid.
Heat Pump Repair
Heat pumps behave differently from furnaces, so an accurate diagnosis matters. We troubleshoot the system, find what is needed, and give you the options and cost for the repair required.
Heat Pump Installation
One system that heats and cools, which suits this climate well — particularly when the air conditioning is also nearing the end of its life.
Emergency Service
Seven days a week for the failures that cannot wait. A no-heat call in January is treated with the same urgency as a no-cool call in July.

Is Your Heat Actually Ready?
A short, honest checklist. If you recognise the left column, an autumn inspection costs a fraction of a January emergency call.
Worth Booking A Inspection
- 01The heater has not been switched on since March and has never had an inspection
- 02It ran fine last winter but made a noise it had not made before
- 03One or two rooms have never heated properly and you have stopped mentioning it
- 04The filter has not been changed since spring
- 05You have a gas furnace and no working carbon monoxide detector on every level
- 06Your system is past twelve years old and has needed a repair in the last two winters
Probably Fine For Now
- 01It was serviced this autumn and the report came back clean
- 02The filter is current and airflow at the vents feels normal
- 03It reaches setpoint without running constantly to get there
- 04Carbon monoxide detectors are installed and within their service life
- 05It starts promptly and holds a steady cycle rather than short cycling
- 06You know roughly how old the system is and it is comfortably inside its expected life
One thing that is not optional: working carbon monoxide detectors on every level of the home if you heat with gas. A cracked heat exchanger gives no smell, no noise, and no warning without an inspection. See heating inspections.
Why Las Vegas HVAC Work Is Its Own Problem
Valley winters are short and mild by national standards, and that shapes almost everything about how heating equipment behaves — usually in ways national advice gets wrong.
Long Idle, Short Season
A valley furnace may run six or eight weeks a year and sit collecting dust the rest. Most first-use failures trace back to that idle period rather than to wear, which is exactly why a pre-season visit catches so much here.
Heat Pumps Suit This Climate
Valley temperatures rarely drop into the range where a heat pump genuinely struggles, so they perform better here than in most of the country. Cold-morning behaviour that alarms homeowners is very often normal defrost operation rather than a fault.
Summer Ages The Equipment
Much of the valley's equipment lives in an attic or on a roof, where summer temperatures shorten component life regardless of how little the heating side runs. Capacitors, contactors, and control boards fail on a schedule set by July.
The upside: a properly sized, maintained furnace often reaches 15 to 20 years here — genuinely easier service than a Midwest winter would give it.
Air Conditioning
Summer comes back. Book cooling maintenance in spring rather than during the first heat wave, when everyone else is calling.
Air Conditioning Repair
Weak airflow, warm vents, or a system that will not start. We find the actual fault and price the repair before touching it.
AC Installation & Replacement
Right-sized replacements based on your home — square footage, insulation, ductwork, sun exposure — not a like-for-like swap.
AC Maintenance & Inspections
Booked in spring, before the first triple-digit week. Catches failing capacitors and low refrigerant while they are still small.
Several components — blower motors, capacitors, contactors, transformers — serve heating and cooling alike, which is a reasonable argument for having both the heating and the cooling side inspected each year.
Commercial Las Vegas HVAC
Offices, retail, restaurants, and light industrial buildings across the valley.
Most valley commercial buildings run rooftop package units — one unit handling heating and cooling, sitting on a curb, exposed to weather every day of its working life. A number of contractors quietly prefer not to climb up to them. We service them.
Commercial work is handled differently from residential: scheduling built around occupancy rather than against it, written documentation after every visit, and one point of contact who already knows the building.

Las Vegas HVAC Questions
On a gas furnace the most common cause is a dirty flame sensor — it stops detecting flame and the control board shuts the gas off within seconds as a safety measure. A failed igniter produces the same complaint. On a heat pump, cooler air on a cold morning is often a normal defrost cycle rather than a fault. All are identified in a single visit — see furnace and heater repair.
Twice a year — once before the cooling season and once in autumn before the first cold snap. The short heating season leads people to skip it, but the ten-month idle period is exactly the problem — desert dust settles on the burners, flame sensor, and blower and causes most first-use failures. Most manufacturers also require documented annual maintenance to keep parts coverage valid. See heating maintenance.
Repair usually wins if the system is under twelve years old, has been maintained, and the failure is a wear part. Replacement usually wins if it is past fifteen years and needing regular attention, the heat exchanger is cracked, or you have paid for two or more significant repairs in the last two years. We lay out both numbers — see furnace installation and replacement.
A full system replacement typically runs $11,000 to $13,000 installed for a standard residential setup, with premium high-efficiency systems running $13,000 to $16,000+ depending on tonnage. A furnace-only replacement is generally less, but varies enough with your existing ductwork, venting, and gas line that quoting sight-unseen would be guessing. Estimates are free and carry no obligation.
It is worth taking seriously, and it is a large part of why annual service exists. A cracked heat exchanger is the main furnace-related risk and is not visible without inspection. Working carbon monoxide detectors on every level of the home are essential if you heat with gas. If a detector sounds, get everyone outside and call 911. If you smell gas, leave the house without touching switches and call Southwest Gas or 911 from outside.
Yes — repair, maintenance, and replacement, along with electric furnaces and rooftop package units. Heat pumps suit this climate well since valley winters rarely reach the temperatures where they struggle, and they behave differently enough from furnaces that an accurate on-site diagnosis matters more than usual. See heat pump repair.
Yes, seven days a week, and we treat a no-heat call in January with the same urgency as a no-cool call in July. Call and describe what the system is doing — give us a call and we will get a technician out to check it over. See emergency HVAC service.
Yes — offices, retail, restaurants, and light industrial, including the rooftop package units most valley commercial buildings run. Commercial work runs through its own section of the site because the equipment, the scheduling, and the documentation are all different. See commercial HVAC services.
