How Long Does it Take AC to Cool A House?

How Fast To Cool My House with AC

As the summer heat begins to roll in, your inside air temperature may follow suit by producing warmer temperatures, taking longer to cool down, and using more energy to function. The time it takes your central A/C unit to cool your home during this time depends on several factors, such as the outside temperature, the size of your home, and whether or not your attic is insulated.

A properly functioning central A/C unit should cool a moderate, four-bedroom home by 10 degrees Fahrenheit in three hours. Although the cooling power of your A/C also depends on your unit’s power, size, and age, your home should be noticeably cooler within a few hours.

Steps to Improve Faster Cooling

If you notice that your AC is running constantly without ever reaching your set temperature, you may have a problem; however, there are a few things that you can do to help.

  • Change your air filters. Dirty filters restrict airflow and thus prevent effective cooling.
  • Check for leaks in your air ducts. Energy Star estimates leaky ducts waste 20-30% of conditioned air.
  • Have a certified HVAC technician, like General Air, check your refrigerant levels. Low refrigerant levels prevent your A/C from effectively removing heat from your home.
  • Have a professional, like General Air, assess the size of your A/C. An air conditioner that is too small for your space will waste energy by running constantly and producing minimal results.
