Six Common Furnace Problems We Fix Every Day
Furnaces can fail in many ways. Some problems are simple and cheap to fix. Others are more complex. Here are the most common issues we see in San Jose homes.
Furnace won’t turn on at all. This usually means a tripped breaker, bad thermostat, failed igniter, or blown fuse. We find the exact cause and restore heat fast.
Furnace turns on but no heat. The blower runs but air is cold. Common causes are a bad igniter, failed flame sensor, or empty gas tank.
Furnace turns on and off too often. Short cycling wastes energy and damages your system. Dirty filter, bad flame sensor, or oversized furnace are typical causes.
Loud banging, popping, or screeching noises. Loose parts, failing blower motor, or cracked heat exchanger make these sounds. We find the noise and fix it.
Pilot light keeps going out. A dirty thermocouple or bad gas valve causes this problem. We clean or replace parts to keep your pilot lit reliably.
Yellow or flickering burner flame. Your furnace flame should be blue. Yellow flame means incomplete combustion and possible carbon monoxide risk. We fix this immediately.
Emergency Furnace Repair – When You Need Heat Fast
A broken furnace in winter is not just uncomfortable. It can be dangerous for children, elderly family members, and pets. Here is what to do when you lose heat.
Check your thermostat first. Make sure it is set to heat mode and the temperature is above room temperature. Replace batteries if needed.
Check your circuit breaker. A tripped breaker cuts power to your furnace. Reset it once. If it trips again, call us immediately.
Check your air filter. A completely clogged filter can shut down your system. Replace it if dirty. Keep spare filters at home.
Check your gas valve. Make sure the gas valve near your furnace is fully open. The handle should be parallel to the pipe.
Call us right away. If none of these steps work, call Innovation Heating and Air. We prioritize no heat calls. Same day service available.
Stay safe while you wait. Use space heaters carefully. Never use your oven for heat. This creates carbon monoxide risk. Dress in warm layers.
