Furnace troubleshooting
Quick answers to the heating problems we get called about most in Vancouver, Woodland, and across Clark and Cowlitz County. Each one tells you what to check and when to call.
01 No heatThe furnace will not turn onMake sure the thermostat is set to heat and above room temperature, and that the furnace switch and breaker are on. If it still will not start, call us. No heat from the ventsReplace a dirty filter and check that the vents are open. If the air is cold or barely moving, the problem is inside the unit. The thermostat screen is blankTry fresh batteries first. A blank screen with new batteries can mean the thermostat or the furnace has lost power. | 02 Wrong heatThe furnace blows cold airCheck that the thermostat fan is set to auto and the filter is clean. Cold air with the right settings needs a technician. Some rooms stay coldClosed or blocked vents, a clogged filter and leaky ducts are the usual causes. Weak airflowStart with the filter. Weak airflow can also point to a failing blower motor. | 03 Cycling and noiseThe furnace turns on and off quicklyOften a dirty filter, a blocked vent or a unit that is overheating. Replace the filter, and call us if it keeps happening. Banging or squealingSquealing often points to a belt or motor bearing, and banging to ignition or ductwork. Turn the unit off and call us. Clicking but no heatThe igniter or burner may be failing to light. |
04 Heat pumpsThe heat pump is not heating in cold weatherMake sure the thermostat is in heat mode. Ice on the outdoor unit, or a unit that runs constantly without warming the house, needs a technician. |
"During a windstorm a tree fell on our furnace — MAS Pro came out quickly. They were friendly, efficient, and genuinely cared whether we stayed warm. I would highly recommend them!"
"Super happy with the service. The technician was at my place within an hour of my call — really impressed with how fast they responded. Jerry found and fixed a blown fuse on my furnace circuit board and helped install my new Ecobee smart thermostat. Everything works perfectly."
"Derrik came out at 4:30 on a Friday to fix my clogged shower. They were professional and clean, and the problem was resolved quickly. So grateful for these guys!"

A gas smell, a carbon monoxide alarm, a burning smell or smoke from the unit. Leave the house and call your gas utility or 911 for gas or carbon monoxide. If the furnace is out in freezing weather with young children, older adults or anyone vulnerable at home, call us. See our emergency HVAC service.
Check that the thermostat fan is set to auto and that the filter is clean. If the settings are right and the air is still cold, the burner, igniter or a safety switch may not be working, and it needs a technician.
Short cycling is often a dirty filter, a blocked vent or a unit that is overheating. Replace the filter and make sure the vents are open. If it keeps happening, call us.
Once a year, before the heating season. See when to service your HVAC system and what scheduled maintenance covers.
It depends on the age of the unit, how often it breaks down and the condition of the parts. A single failed part on a newer unit is usually a repair. An older unit that keeps failing is worth a replacement conversation. See heat pump vs furnace in Vancouver.
