How long should it take to cool a house from 80 to 72?

As previously mentioned, there are a couple of factors that profoundly affect the time taken for your house to cool down. If you have a four-bedroom house, it will take approximately 3 hours to cool it from 80 to 72.

You should keep in mind that this will only be possible with an air conditioner that has excellent performance.

Why does it take longer to cool down a house?

This is affected by the type of air conditioner you are using and the size of your house. If you have a significant and powerful air conditioner, you will be able to cool down your home within a few hours, unlike using a small and less powerful air conditioner.

You should keep in mind that the cooling power of your air conditioner highly depends on its size, power, and size of your house. If you achieve the right aspects, your home will cool down within a few hours.

Maintaining your air conditioner

For excellent performance, you should consider maintaining your air conditioner. This will enable it to reach the set temperature within a few hours. Here are some things you should carry out with your air conditioner;

  1. Change air filters: Having dirty air filters will restrict airflow, which prevents effective cooling in the house.
  2. Leaks in the air duct: Always assess for a leak in the air duct since most of the conditioned air is wasted due to leaky air ducts.
  3. Have a technician evaluate your air conditioner: Let the technician evaluate the refrigerant level since a low level of refrigerant prevents the air conditioner from removing heat from your house effectively.

High temperatures and air conditioners

If you live in places such as Atlanta, where outside temperatures can be reached 93 degrees, your air conditioner performance will be profoundly affected.

This is because most air conditioners are designed to operate under a specific temperature level. Therefore, when the outside temperature exceeds the recommended temperature range, your air conditioner will struggle to attain the set temperature since it was not designed to get rid of such amount of heat.

When purchasing an air conditioner, always assess its outside temperature range and compare it to your location. This will help you choose an air conditioner that best suits your location.

Furthermore, you should always keep in mind the size of your house before purchasing an air conditioner.
