Does Switching Back and Forth Between Heat and AC Hurt Your HVAC System?

Spring in the Midwest can give us quite the temperature variation; it’s hot one day and cold the next. Sometimes we get all four seasons in one week. It can be a challenge to regulate your home’s temperature. During the day you may need to turn your air conditioning on, but at night you may find that it is too cold to fall asleep. Because of this many homeowners switch units back and forth between heat and air conditioning. 

But will this switching back and forth damage your unit? 

The good news is, NO! Generally, doing this will not cause any problems with your system and inherently it isn’t bad for your unit. There are a few important things you should know before switching back and forth. 

Because of the demands that switching back and forth puts on your HVAC unit, preventative maintenance of your HVAC system becomes even more important to make sure everything runs smoothly. Here are some more tips to ensure that you are switching between heat and air conditioning in the safest way possible. 

● Let your unit completely finish its current cycle before switching it. Once it has stopped, shut your unit off completely. 

● Wait five or more minutes between turning off one system and turning on the other. If you switch them too quickly an electrical issue could arise and you are at risk of tripping your breakers. 

● Make sure you don’t set the temperature to something drastically different right away when switching between systems. Raise or lower the temperature by just a couple of degrees at a time. This will keep your system from overworking, and it will help it operate more efficiently.
