Furnace Repair in Reno: what's different
Reno furnaces run for months each winter, so inducer motors, igniters and flame sensors wear out more often than in Southern Nevada. High-efficiency furnaces also fail when condensate lines freeze outside on cold nights.
Older homes in the Old Southwest and Midtown can have gravity furnaces, floor furnaces or boilers that need techs who still work on that equipment.
Reno also sits at about 4,500 feet, so furnaces need correct gas pressure and combustion settings for altitude. A furnace that keeps locking out on cold nights should have its vent, intake and condensate trap checked before parts are replaced, and every repair should end with a carbon monoxide reading.
Reno climate
Winter nights regularly fall below freezing, with inversions trapping cold air in the valley. Summers reach the upper 90s and low 100s, and wildfire smoke from California and Nevada fires often affects air quality.

FAQ
Furnace Repair questions
Why did my high-efficiency furnace stop on a cold Reno night?+
A frozen or clogged condensate drain is a common cause. The pressure switch senses water backing up and shuts the furnace off.
Why does my furnace turn on then off right away?+
The most common reason is a dirty flame sensor, which can't prove the flame so the board shuts the gas off. Other causes are a weak pressure switch or a blocked vent.
Is a cracked heat exchanger dangerous?+
It can be, because it may let combustion gases mix with house air. A tech will usually shut the furnace off and red-tag it until it is repaired or replaced.
