Gas furnace repair
Common furnace problems include failed hot-surface igniters, dirty flame sensors that shut the burners off after a few seconds, pressure switch and inducer motor faults, blower motor failures and control board issues. Furnaces that sat unused all summer often need a cleaning and inspection when they're first turned on.
Heat pump repair
A heat pump heats by running in reverse. Problems we see include systems stuck in cooling mode (often a reversing valve or control issue), outdoor units that ice up and don't defrost, and systems that lean on backup electric heat strips far too much, which shows up as a very high winter power bill.
Electric heat and air handlers
Electric heat strips in an air handler can fail from burned-out elements, relays or limit switches. We test and replace the failed parts.
Carbon monoxide safety
A gas furnace with a cracked heat exchanger or blocked venting can leak carbon monoxide. Every home with gas appliances should have working CO alarms. If an alarm sounds, get everyone outside and call 911.
Before you call
- Check that the thermostat is set to heat and its batteries aren't dead.
- Replace a clogged filter; furnaces can shut down on overheating when airflow is blocked.
- Check the breaker and the furnace power switch, which often looks like a light switch near the unit.
Valley-specific heating issues
First cold snap furnace odors
A dusty burning smell for a few minutes the first time the heat runs in fall is usually dust burning off the heat exchanger after months of sitting idle. It should fade quickly. A smell that lingers, smells like hot plastic or electrical insulation, or comes with a tripped breaker is different, and the system should be turned off until it's checked.
Heat pump defrost cycles on frosty mornings
On cold mornings in the valley, frost can form on the outdoor coil. A working heat pump periodically switches into defrost, and you may see steam rising from the unit and hear a whoosh. That's normal. A coil that stays coated in thick ice for hours, though, points to a defrost control, sensor or refrigerant problem we should look at.
Attic furnaces and limit switch trips
Furnaces installed in attics or tight closets often have restricted airflow from crushed ducts or blocked returns. When air can't move, the furnace overheats and the limit switch shuts the burners off, so the heat cycles on and off. Fixing the airflow is usually the real repair. Our duct repair page covers what we look for.
Uneven heat in two-story homes
Heat rises, so upstairs rooms in two-story homes often run warm in winter while downstairs feels drafty. Balancing dampers, closing a few upstairs vents partially, or zoning can help. A properly placed thermostat also matters, since one at the bottom of the stairs reads differently than one in a hallway.
Common questions
Why does my furnace start and then shut off?
A dirty flame sensor is a very common cause: the burners light, the furnace can't confirm the flame, and it shuts down for safety. Overheating from a clogged filter is another.
Why is my heat pump blowing cool air in winter?
Heat pump air feels cooler than furnace air even when it's working. If the house isn't warming, the system may be stuck in cooling mode, low on refrigerant, or not defrosting.
Do you repair heating systems at night?
Yes. We're available 24 hours a day, 7 days a week.
