Can I Run the Air Conditioning and Heat in the Same Day?


Pen and paper with check boxes for Yes, No, and Don’t Know

We’ve all been through those days when the weather seems to play tricks on us. One moment, the chilly breeze has you wrapping yourself in a warm blanket, and just as you’re settling in, a sudden surge of warmth has you seeking respite from the unexpected heat. It’s a dance between the thermostat and our comfort levels, and it can be quite the juggling act.

What Is the Best Way to Switch Between AC & Heat?

Wondering how to seamlessly transition between your air conditioning and heating systems without causing undue stress to your HVAC system? Here’s a step-by-step guide to help you make the switch efficiently:

  1. Turn your thermostat to AUTO.
  2. Allow the system to finish its current cycle.
  3. Once it stops, turn the thermostat OFF.
  4. Wait five minutes and then flip to the other system.
  5. Set the temperature close to your current temperature.
  6. Gradually adjust the settings by 5 degrees.

Why Wait Before Switching Temperatures?

You may wonder why you must wait before going from one temperature setting to the next. The reason has to do with how your HVAC system works. When you switch quickly from a cold setting to a hot setting or vice versa, the compressor could get stuck. This makes the system work harder and can cause problems if the weather constantly changes between hot and cold.

Also, slowly switching between heating and cooling ensures that both systems aren’t running simultaneously. This can put too much stress on your heating, cooling, and ventilation system, which will use more energy. Also, it’s important to remember that the temperature of a room doesn’t change instantly. When big changes are made to the environment, it takes a while for the temperature to settle. 

What Should You Avoid When Running Your AC & Heating System on the Same Day?

When navigating the unpredictable weather by using both your AC and heating systems on the same day, it’s essential to be mindful of certain practices to ensure the longevity of your HVAC system and maintain energy efficiency.

Mistakes to Steer Clear of

While it’s essential to understand how to use your HVAC system efficiently, it’s equally crucial to be aware of common missteps that homeowners often make, including:

  • Do not make a thermostat adjustment in the middle of a cycle. It will cause them both to run, but not optimally, as they require more energy.
  • Do not change to hot or cold directly after a cycle has ended. Let it rest for a few minutes so both temperatures don’t run simultaneously.
  • Do not increase or decrease the thermostat several degrees from the existing temperature in the room. Gradual temperature changes can help improve your efficiency, and you will not force your HVAC or other system to work harder.

By avoiding these pitfalls, you can ensure a longer life span for your HVAC system, reduce unnecessary energy consumption, and maintain a comfortable living environment.

Recommendations You Should Follow

To ensure the optimal performance and longevity of your HVAC system, it’s not just about avoiding mistakes; it’s also about adopting best practices that enhance its efficiency, such as:

  • Install a smart or programmable thermostat and program your favorite temperatures, which avoids overcooling or heating empty rooms when you are not home.
  • Replace your air filters every six months to improve the air quality and not make your HVAC work harder.
  • Schedule routine maintenance, but if your system malfunctions, don’t wait for the problem to worsen – request an HVAC repair!
