How To Switch From Air Conditioning To Heat

While switching over from air conditioning to heat may sound like a simple task, you must ensure you make a proper and efficient switch each and every time. Use our guide below to save both energy and money.

Preparing To Switch From AC To Heat

Performing a proper seasonal shutdown on your AC unit once the weather warms up is essential. This includes such measures as cleaning the coils, drainage, and covering the unit for the upcoming winter. Now let’s take a look at how to properly switch your AC to heat.

How To Switch From AC To Heat

Start by adjusting the thermostat to the desired temperature, then switch your settings from “cool” to “heat”. You should hear the AC fan turn off at this time, as well as a separate click as your furnace ignites. Gas will begin to flow into the heater, so give the unit about 30 seconds to achieve this.

If your unit continuously shuts down after this step, it’s most likely due to the furnace sensor not being able to detect the flame. Ensure the gas valve is open and providing gas to the unit. Next, ensure the thermocouple (flame rod) is clean. It may have collected dust over the past few months of use.

You can use fine sandpaper to clean the thermocouple if it appears dirty. Once you have cleaned the thermocouple, you may notice a distinct smell as dust. It’s suggested to open your windows to provide good ventilation to rid the home of this odor.
