There is nothing quite as unsettling as waking up to a freezing house in the middle of a Maine winter. When the temperature drops outside, your home should be your sanctuary. But when your boiler or furnace stops working correctly, panic can set in quickly.
Before you call for emergency service, there are several simple troubleshooting steps you can take. Sometimes, the solution is as easy as flipping a switch. Other times, it requires the steady hand of a professional. Here is a guide to help you figure out what might be wrong with your heating system and when to call in the experts at Sail Energy.
It sounds obvious, but many “no heat” calls turn out to be simple fixes that homeowners can handle themselves. Before worrying about expensive repairs, run through this quick checklist:
Is your thermostat set to “HEAT”? It is easy to accidentally bump it to “OFF” or “COOL,” especially during transitional seasons. Make sure the temperature setting is at least five degrees above the current room temperature. If it runs on batteries, try swapping them out for a fresh pair.
Most heating systems have a power switch located near the unit (it often looks like a red light switch plate) or at the top of the basement stairs. Ensure this hasn’t been accidentally turned off. Additionally, check your circuit breaker panel to see if the breaker for your heating system has tripped.
If you rely on heating oil or propane, check your tank gauge. If you are below an eighth of a tank, you might have run out of fuel. While run-outs happen, they can cause sludge to be pulled into the fuel lines, leading to clogged filters.
Pro tip: Enroll in Sail Energy’s automatic heating oil or propane delivery to ensure this never happens again. Our Total Comfort Bundle customers enjoy this convenience along with price protection.
For furnace owners, a dirty air filter is a leading cause of system failure. When filters get clogged with dust and debris, airflow is restricted. This can cause the furnace to overheat and shut down as a safety precaution. Check your filter and replace it if it looks dirty.
If you have gone through the checklist above and your system still isn’t producing heat—or if it is making strange noises—it is time to call for backup. Here are signs that you need a professional technician:
