Does The Outside Temperature Affect My AC?

June 16, 2020

Outdoor temperatures have a large impact on your air conditioning system. It has to work hard when temperatures soar and may not be able to keep up. These are the ways in which outdoor temperatures affect how well your AC system works.

How AC Units Deal With Hot Outdoor Temperatures

Most cooling systems are maxed out when the outdoor temperature exceeds 95 degrees. At that point, they can’t work any harder. At 95 degrees, they can keep your house around 78 to 80 degrees. If you turn the thermostat below 78, it won’t make your residence any cooler.

When outdoor temperatures aren’t that hot, the heat exchanger does most of the work cooling the air inside your home. As the temperature gets hotter, the compressor has to work harder. This puts stress on the compressor and, over time, will likely shorten its lifespan.

How You Can Help Your AC in Hot Conditions

You shouldn’t set the thermostat any cooler than the outdoor temperature minus 20 degrees. This is the most a properly sized air conditioner can cool a home. This will help your air conditioner to operate at its maximum capacity while not having it strain to do even more.

You should also make sure the air filter is clean. A dirty air filter restricts airflow and makes your air conditioner work harder than it needs to. The air filter should be pulled out and examined once a month. It needs to be replaced with a new one every two to three months.

Don’t Turn Your AC Off

When you’re home, set the thermostat to 78 degrees. Set it to 85 degrees when you’re away for the day. If you turn off the AC instead, the unit will have to work incredibly hard to bring your residence’s temperature down.
