Furnace Repair in Reno, NV
Most furnace no-heat calls are caused by a dirty flame sensor, a failed igniter, a clogged filter tripping the high-limit switch, or a blocked condensate line on high-efficiency units. A technician reads the furnace's error code and tests the safety controls before replacing anything.

Reno furnace repair calls spike during the first hard freezes in November and again during January cold snaps. High-efficiency furnaces in garages and attics often lock out when their condensate drain freezes, and snow can block their PVC vent pipes.
Older homes in the Old Southwest and Midtown may have converted gravity furnaces, floor furnaces or boilers, which call for a technician experienced with older equipment and venting.
In newer neighborhoods like Somersett, Damonte Ranch and South Meadows, the most common repairs are dirty flame sensors, failed igniters and inducer motors on furnaces that are 15–20 years old. Altitude matters too: at about 4,500 feet, furnaces have to be set up for high altitude, and a unit that was never adjusted can overheat and trip its limit switch on cold nights.

Frequently asked questions
My Reno furnace shut off during a freeze. What should I check?
Check that the outdoor vent pipes are clear of snow and ice. If the furnace is in the garage or attic, a frozen condensate line is a common cause. Call for service if it won't restart.
My furnace blows cold air. What should I check?
Check the filter, thermostat setting and the furnace switch first. If the burners never light or light and go out, the flame sensor or igniter is the likely cause, and a technician should diagnose it.
What if my heat goes out in a Reno freeze?
Call for emergency service, keep interior doors open, open cabinet doors under sinks on outside walls, and let faucets drip to reduce the risk of frozen pipes while you wait.
How long do furnaces last in Nevada?
Gas furnaces commonly last 15–20 years. High-efficiency units can fail sooner if condensate drains are not maintained.
