Do you have a digital thermostat? If so, you’ll need to change the batteries once you notice the low battery icon on the screen. Your furnace depends on the thermostat to tell it when it needs to heat your home. Once the batteries are dead, the furnace has no way of knowing when the temperature drops. Fortunately, changing the batteries in your thermostat is easy enough to do without a HVAC contractor.
Look for the exterior battery compartment (near the top of the thermostat) and push down on the tab. Slide the compartment sideways to release it from the thermostat and replace the batteries. Most thermostats take AA or AAA batteries, which you probably already have in your cupboards. Slide the compartment back in until it snaps into place.
As the weather cools in autumn, you’ll need to change your thermostat setting from “Cool” to “Heat.” Otherwise, your home furnace won’t turn on when you need it. When your thermostat is set to “Cool,” it’s programmed to turn the air conditioner on once the temperature rises above what you set it to. Even if the temperature drops below what’s considered comfortable, the thermostat won’t tell your furnace to kick on until you change the setting to “Heat.”
If you have a programmable thermostat, make sure it’s displaying the correct day and time. You’ll also want to check that the AM and PM settings are correct since many of our customers program their thermostats so there’s less heat when no one’s at home. If your schedule has changed recently, this could also be the issue.
When was the last time you changed the furnace filter? While we can change the filter during routine furnace service, you may need to change it more often if you have pets in the home. The furnace filter can also get clogged more often when people smoke inside the house.
Depending on the filter and the conditions inside your home, you may need to replace the filter every 1 to 6 months. You’ll be able to tell that the furnace filter needs replacing if it’s noticeably gray in color by dirt and dust.
The furnace filter is responsible for trapping dirt, dust, hair, and other air contaminants. However, yourwill be forced to work harder and use more energy if it can’t pass air through a clogged filter. It may even shut off entirely. A clogged filter also means that you’ll be breathing in all those contaminants released into the air.
Check That Furnace Switch is in “On” Position
The furnace switch often looks like a regular light switch, which is why homeowners can mistakenly turn them off. Look for the furnace switch on the unit itself or on a nearby wall. Once you turn the furnace switch back on, wait a few minutes for the heat to turn back on.
