By taking the time now to care for your furnace correctly during the summer, you’ll be able to enjoy warm winter months with fewer repair bills or issues. Let’s get started!

Turning off your furnace for the summer doesn’t have to be a difficult task. Here are the steps you need to take:

  1. Turn off power supply: The first step is to turn off the power supply to your furnace. This can usually be done from your breaker box or by unplugging it directly from the unit itself.
  2. Close the gas supply valve: If you have a gas powered furnace, make sure that you close the gas supply valve. Be sure to follow all safety protocols when doing this. 
  3. Clean out any debris: After turning off the power and closing the gas supply line, it is important to clean up any debris in or around the furnace. This is important to ensure the unit runs properly in the winter months.
  4. Check thermostat: Once you have finished all of the previous steps, make sure to inspect your thermostat and confirm that it is set to “off”, “cool  or “summer mode.” This will prevent any unnecessary energy waste.

Schedule Furnace Maintenance

The warmer months while your furnace is not in use is a great time to schedule any necessary maintenance on your furnace. A professional technician can inspect the unit, make repairs if needed, and give you advice regarding its performance.

Change The Filter

Finally, it is important to change the filter to be sure it is ready to run when the cooler temperatures arrive again. A dirty or clogged filter can be a fire hazard and can also reduce the efficiency of your unit.

Clean Ducts

In addition to replacing the filter, it is also a good idea to clean the ducts.  This will help to remove any buildup of dust and debris that would otherwise clog the system.


By following the simple steps outlined above, you can easily turn off and maintain your furnace this summer. Taking the time to take care of your furnace now will help to ensure that it runs efficiently in the cooler months ahead. Keep these tips in mind when turning off your furnace this summer and make sure to call in a professional if any repairs are needed. With a little bit of effort, you can enjoy warm winter months with fewer repair bills or issues.
