Commercial Heating Repair and Installation in Las Vegas
Installation, repair and maintenance for rooftop gas/electric units, heat pumps, unit heaters and boilers. Las Vegas winters are mild, but a cold building at opening time still needs fixing fast.

The commercial heating equipment we service
Heating in a Las Vegas commercial building usually comes from the same equipment that cools it. We install, repair and maintain these types, on all makes and models:
- Rooftop gas/electric units. A packaged unit that cools with a refrigeration circuit and heats with a gas burner and heat exchanger in the same cabinet. It is a very common setup on shops, offices and restaurants.
- Heat pumps. Rooftop or split systems that reverse the refrigeration cycle to move heat indoors, usually with electric heat strips as backup.
- Unit heaters. Gas or electric heaters hung from the structure in warehouses, shops, garages and loading areas, where there is no ductwork.
- Boilers. Hot-water systems that feed heating coils, fan coils or radiant loops in larger buildings. Our boiler services page goes into more detail.
Why heating gets overlooked in Las Vegas
Winters here are mild, with cold desert nights, and heating loads are light next to cooling. So the heating section of a rooftop unit sits idle from spring to late fall. Then the first cold morning arrives, every thermostat in the building calls for heat at once, and faults that built up over the quiet months appear together. Dust has settled on burners and heat exchangers. Ignitors and flame sensors have aged. A pressure switch or gas valve that worked last February no longer does.
The timing is poor as well. Buildings are coldest right before opening, so a failed heater is discovered by the first staff and customers through the door. A heating check in the fall, done along with the post-summer look at the cooling side, finds most of these faults while there is still time to order parts. Because the blower, filters and controls are shared, anything corrected there helps your commercial air conditioning too.
Heating repairs and safety checks
The calls we get most often:
- The blower runs but the air is cold.
- Burners light, then drop out after a few seconds, often because of a dirty flame sensor.
- The unit shuts off on its high-limit switch, usually because dirty filters or a slipping belt have cut airflow.
- A heat pump ices over outdoors or stays stuck in cooling.
- A unit heater will not ignite, or its fan runs without heat.
With gas equipment we do more than get the flame back. We inspect the heat exchanger for cracks and corrosion, check the flue and venting, measure gas pressure and confirm the safety switches work. A cracked heat exchanger can let combustion gases into the air supplied to the building, so the unit stays off until it is repaired or replaced.
If you smell gas, get everyone out of the building, then call the gas utility or 911 from outside. Call us for the repair once the utility has made the site safe. If a carbon monoxide alarm sounds, move everyone to fresh air and call 911.
Installing or replacing a commercial heating system
On a rooftop unit, heating and cooling come in one cabinet, so heating is normally replaced as part of a full unit changeout. The main decision is gas/electric or heat pump. Gas makes sense where a gas line already reaches the roof and the building needs a fast warm-up. A heat pump handles a typical Las Vegas winter day comfortably and avoids gas piping and flue work, but the electrical service must have enough capacity for it.
We size equipment from the building's load, not from the old nameplate. The previous unit may have been wrong for the space, or the space may have changed. Installation covers the curb, duct connections, gas piping or electrical work, permits and the crane lift. At start-up we set gas pressure, confirm the temperature rise is within the range on the nameplate and test every safety control. For unit heaters we also check mounting height, clearance from stored goods and venting. If the budget is the sticking point, ask about financing, which is available subject to approved credit.
Seasonal maintenance and service calls
Yearly heating service is short and worth doing: clean the burners and flame sensor, test ignition and safeties, inspect the heat exchanger and flue, and check defrost and backup heat on heat pumps. It fits naturally into a commercial HVAC maintenance schedule.
When something fails outright, licensed technicians are on call 24/7 at 702-497-0888. Tell us whether the equipment is a gas unit, a heat pump or a boiler, and whether any alarm has sounded. It changes what we bring and how we approach the building.
Frequently asked questions
Still have a question? Call 702-497-0888.
Why does the heat smell like burning the first time it runs?
It is usually dust burning off the heat exchanger or electric elements after months of sitting idle. The smell should fade within the first hour or so of operation. If it lingers, smells like hot wiring or melting plastic, or comes with smoke, shut the unit off and call us. A gas smell is different: leave the building and call the gas utility from outside.
Is a heat pump enough to heat a business in Las Vegas?
For most buildings, yes. Heat pumps work efficiently in mild winters like ours, and backup heat strips cover the coldest nights and the defrost cycle. The questions to settle are whether your electrical service can carry the load and how quickly the space has to warm up before opening. We check both before recommending one.
What should we do if we smell gas in the building?
Get everyone out right away. Do not stop to look for the source, and do not operate light switches or equipment on the way out. Once you are outside and away from the building, call the gas utility or 911. After the utility has shut off or secured the gas, call us at 702-497-0888 to find and repair the leak.
How often should commercial heating equipment be serviced?
Once a year, ahead of the heating season, is the usual recommendation for gas-fired and heat pump equipment. In Las Vegas that means a fall visit, which pairs well with a check of the cooling side after a hard summer. Boilers and equipment that runs long hours may need more frequent attention.
Why is our rooftop unit blowing cold air in heating mode?
The fan is running but the heat source is not. On a gas unit the cause is often a failed ignitor, a dirty flame sensor, a tripped safety switch or a gas supply problem. On a heat pump it may be a defrost cycle, which is normal and brief, or a reversing valve fault. Check that the thermostat is set to heat, then call.
