How Much Energy Does an AC Unit Use?

TechXpert verified by Ken Kontra

Your AC unit can use more than 4000 watts of power on a hot summer day. In other words, your AC consumes a lot of energy to maintain the temperatures set on your thermostat. In turn, it’s important to learn how you can conserve energy to benefit your AC unit and your wallet.

Why Your AC Uses a lot of Energy

You’ll need more than a magician to make cold air appear in your home. Your AC system follows a domino effect of energy consumption: it contains numerous tubes, coils, and other large parts like the compressor that work simultaneously to deliver cold air throughout your home. And of course, the cooler the temperature you want, the more energy your unit requires.

Your AC unit can only be energy efficient with your help. If you start noticing higher levels of energy consumption, it could be because of poor maintenance, refrigerant or thermostat issues, drainage problems, or filthy filters.

Big on BTUs

BTU stands for British Thermal Unit and is the international measure of energy. Your AC system uses BTUs to measure the quantity of heat your unit can remove from a room. A BTU is the amount of heat needed to raise one pound of water by one degree Fahrenheit.

Conserve AC Energy

When summer hits, so does your need for cooling. If you want your AC unit to work efficiently for a long period of time, it’s important to conserve energy in some of the following ways:

  • Set your thermostat one or two degrees higher

  • Use ceiling fans to circulate cool air

  • Make sure your home is well-insulated

  • Keep air ducts and filters clean

  • Keep furniture away from vents

  • Keep other appliances away from your thermostat

  • Keep AC temperature lower at night

Reduce Energy Costs

Conserving energy for your AC will keep it healthy for longer and give you more bang for your buck. To reduce energy costs, you may want to consider:

  • Scheduling annual maintenance check-ups

  • Installing a programmable thermostat

  • Avoiding heat buildup during the day

Maximize Energy to Maximize Benefits

Losing energy because your AC unit is using too much? Once summer rolls around, it takes a lot to keep cool. However, there are a number of creative ways to maximize the energy efficiency of your AC unit to enjoy a more comfortable season.
