Furnace Repair
Furnace repair in Nevada
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.

Northern Nevada winters regularly drop into the teens, and homes around Lake Tahoe see sub-zero nights. A furnace that fails at 2 a.m. in January is an urgent problem, especially where water pipes are at risk of freezing. In the Las Vegas Valley, furnaces run fewer hours but often fail on the first cold night of the year after sitting unused since spring.
Gas furnaces have multiple safety controls: flame sensor, pressure switch, high-limit and rollout switches. These shut the furnace off when something is wrong. Repeated lockouts point to a real problem such as poor venting, a cracked heat exchanger or restricted airflow, and should be diagnosed rather than reset over and over.

Frequently asked questions
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.
