Is It Okay to Run My AC and Heater on the Same Day?

As temperatures begin to rise, you may find yourself questioning whether it’s okay to switch back and forth between your air conditioner (AC) and your heater on the same day. The short answer is yes, but there are a few things you should keep in mind before you do. Read on to learn more about how to safely alternate between your AC and heater on the same day without wasting energy or putting wear and tear on your equipment.


When alternating between heating systems, it’s important that you turn off one system before turning on the other. This ensures that both systems aren’t running at the same time, which can waste energy and put unnecessary strain on your HVAC system. Additionally, make sure that both systems are properly tuned up before switching them out; if they’re not working optimally, they’ll require more energy to run efficiently.

Another key factor to consider when alternating between heating systems is temperature control. When switching from heat to cool or vice versa, always set the temperature at least five degrees higher or lower than the current room temperature. This helps ensure that your system works as efficiently as possible while providing an optimal level of comfort for your home. Lastly, remember that it takes some time for temperatures in a room to adjust after either system has been turned off or switched out; be patient with the process!


There are several steps you can take to make sure that alternating between your AC and heater goes as smoothly as possible. First off, install a programmable thermostat so that you can easily adjust temperatures throughout the day based on when you’re home and what activities you’ll be doing in each room; this will help save energy by avoiding over-cooling or over-heating parts of your home while no one is there. Secondly, replace any air filters regularly—about every six months—to ensure optimum performance of both systems; dirty air filters impede airflow significantly, which can cause both systems to work harder than necessary (leading again to wasted energy). Finally, if either system isn’t performing quite right or isn’t functioning at all, make sure to call a professional HVAC service technician right away—don’t wait until it gets worse!

At first glance it may seem strange to think of using both an AC and heater on the same day – but with careful consideration and proper maintenance practices it is totally possible! By following these tips for alternating between heating systems – such as making sure one system is turned off before turning another one back on – you can rest easy knowing that switching back and forth won’t cause excess wear-and-tear on either system or waste energy unnecessarily. So go ahead – enjoy the best of both worlds! You deserve it!
