My Furnace Won’t Turn Off
Serving Vancouver WA | Clark County Washington
Furnaces work with your thermostat. When the temperature in your home drops to a certain degree, your furnace will kick on and stay on until the temperature reaches your desired temperature. But what if your furnace never turns off? Below are some common reasons why your home furnace may not be turning off. If you’re experiencing any of these issues, contact the experienced technicians of Vanport Mechanical in Vancouver WA.
Check Your Thermostat Settings
This should be the first thing you check. It may sound easy, but a thermostat setting is often the issue. Make sure your thermostat is set to “auto” and not “on”. This will make sure your furnace is only blowing air when heat is produced. Also, check the temperature setting, and make sure it is set to heat and not cool.
Check Your Air Filter
Your furnace pulls air from your home and into the system. However, before it reaches the system, the air passes through an air filter where debris is filtered out. If you have a dirty air filter, it will restrict air from passing through the system, which may cause your furnace to run longer. Change your air filter, if you’re furnace is still running after an hour or so, contact Vanport. Our HVAC technicians will inspect your system and figure out what is really going on.
Check the Fan Relay Switch
This small component tells your furnace when to turn on and off. Turn your thermostat off. If your furnace blower doesn’t turn off, there may be a malfunction with the fan relay switch or the thermostat. An inspection by an HVAC technician will be able to repair whichever component is the issue.
Check For Any Leaky Ductwork
Overtime the ductwork in your home may become loose or seals may open up. Your home will have two types of ductwork: return and supply. Return ducts suck air into your furnace so it can be heated while supply ducts blow the heated air throughout your home. If you have leaky supply ducts, the hot air could leak into your attic or crawl space, causing your furnace to work harder to heat your home. If you’re not sure how to safely inspect your ductwork or you need your ducts repaired contact Vanport. We’ll inspect your system and make any necessary repairs to get your heat distributed as it should once again.
Regular Maintenance Can Help Prevent Furnace Issues
Many of the issues listed above can be prevented with regular maintenance. We recommend having your system be professionally serviced at least once a year. Regular inspections and maintenance can help your system run properly and efficiently. And it will save you in costly repairs later. If you’re interested in our maintenance services, contact us.
