Does the Heat Outside Affect My Central AC?

- 9:00 am - May 14th, 2024

Things in Virginia are heating up, and you might be wondering if the hot air outside affects your central AC system. The answer is yes, absolutely! Let’s explore how extreme heat can impact your AC, and what you can do to keep it running smoothly.


It’s important to note that most air conditioners lower the inside temperature by 20 degrees, meaning that the temperature in your home will be about 72 degrees if it’s 92 outside. During scorching temperatures, your AC works harder to remove heat from your home, putting a strain on the system. This can lead to:

  • Reduced efficiency: The hotter it is outside, the less efficient your AC becomes. This translates to higher energy bills.
  • Increased wear and tear: Running your air conditioner constantly in high heat can shorten the lifespan of your AC unit by causing it to work harder.
  • Damaged parts: The extreme weather causes your compressor to work overtime to speed up the cooling process, and that might cause damage to it.


Now that we’ve discussed the potential problems that come with high outdoor temperatures, here are some ways to help ensure your AC is cooling your home efficiently:

  • Air filter changes: We recommend replacing your air filter at least once a month to prevent airflow blockage, which can strain the system.
  • Thermostat settings: Adjust the temperature of your thermostat by a few degrees to reduce the workload on your AC.
  • Minimize heat gain: Close blinds or curtains during the day to prevent sunlight from heating your home.
  • Regular maintenance: Schedule regular maintenance checks with Parker Oil & Propane to help ensure your AC is operating efficiently.
