Ten months of heat, on nights near freezing
Your furnace or heat pump runs September through June here. Winter nights average 33°F from December through February, and a system that runs that many months a year does not get much rest between cycles. That wear falls on the parts that start it up each time it kicks on.
Most homes in Shelton heat with electricity, so when the heat goes out, there is no backup burner to lean on. Summer afternoons average a mild 72°F, so the system barely runs on the cooling side, and trouble almost always shows up as a house that will not warm up. Washington saw 23% of households lose power for at least a day in 2024, and an electric furnace or heat pump sitting cold that long is worth checking once power is back.

Washington requires contractors to register with the state.
Registration puts the business on file with the Department of Labor and Industries. There is no trade exam behind it, so the state is not testing what the contractor knows about heating and cooling systems, only keeping a record that the business exists.
For this repair, that record is what you have to go on here. Washington is not testing or licensing the person working on your furnace, air conditioner or heat pump, so the registration confirms the business is on file and nothing more.

- Why is my heat not working?
- Most often the thermostat, the igniter, or the power to the unit is the problem. If the thermostat screen is blank, check the batteries first. If the furnace runs but never lights, the igniter may have failed, and a contractor will need to test and replace it. With most homes here relying on heat for ten months of the year, it is worth checking the breaker too, since a tripped breaker looks the same as a dead furnace from the thermostat.
- Why is my system running but not cooling the house?
- Check the air filter first. A clogged filter blocks airflow across the coil, and the system can run for hours without actually cooling the air. If the filter is clean and the vents are open, the coil itself may be dirty or low on refrigerant, and that needs a contractor to check. Summer afternoons here only average 72°F, so a system that runs constantly without keeping up is worth having looked at rather than left running.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it is set to heat or cool as needed and that the batteries are not dead. Then check the breaker panel for a tripped switch, since that will stop the system cold with no other symptoms. If you have a furnace, look at the filter next. A filter clogged with dust can starve the system of airflow and cause problems that look like something more serious. If none of that explains it, a contractor will need to diagnose the actual part that failed.
