What to Do When Your Heat Stops Working: A Homeowner’s Guide

There’s nothing worse than waking up on a chilly morning only to find that your heat has
stopped working. Before you panic, there are a few troubleshooting steps you can take to
potentially restore warmth to your home. Here’s a step-by-step guide to help you diagnose the
problem and determine whether you need professional assistance. Not having heat in your
home can be dangerous, leading to risks such as frozen pipes, increased susceptibility to
illness, and even potential carbon monoxide buildup if alternative heating methods are used
improperly.
  • Step 1:
    Check the Thermostat
    The first thing to do is ensure your thermostat is set
    correctly.
    ● Make sure it is set to “heat” mode.
    ● Check that the temperature setting is higher
    than the current room temperature.
    ● Replace the batteries if your thermostat runs
    on battery power.
    ● Try increasing the temperature a few degrees
    to see if the heat turns on.

    Step 2:
    Inspect the Power Supply
    If your heating system isn’t turning on, check for
    power issues.
    ● Verify that the furnace switch is in the “on” position.
    ● Check your electrical panel for a tripped breaker and reset it if necessary.
    ● If you have a gas furnace, make sure the pilot light is lit.

    Step 3:
    Check the Air Filter
    A clogged air filter can restrict airflow and cause your heating system to shut down as a safety
    precaution.
    ● Locate the filter and check for dirt and debris.
    ● Replace the filter if it looks dirty.
    ● Regularly changing filters helps maintain efficiency and prevents breakdowns.

    Step 4:
    Inspect Vents and Registers
    Blocked vents can prevent warm air from circulating properly.
    ● Ensure all vents are open and unobstructed.
    ● Remove any furniture, rugs, or other objects blocking airflow.

    Step 5:
    Look for Furnace Error Codes
    Many modern furnaces have an LED indicator that flashes error codes.
    ● Check your furnace manual to decode the flashing light pattern.
    ● This may help pinpoint the issue before calling for service.

    Step 6:
    Reset Your System
    Sometimes, simply restarting your system can resolve minor issues.
    ● Turn off your heating system at the thermostat.
    ● Shut off power to the furnace at the breaker.
    ● Wait a few minutes, then turn everything back on.
