Energy Consumption in Centerville, Utah

When it’s time to replace your old, inefficient, or broken air conditioning system in Centerville, UT, you’ll need to choose the right size for the new unit. Air conditioners are sized in a couple of ways. One is British thermal units, and the other is in watts. The wattage refers to how much power the air conditioner requires to cool your home. Read on to learn about how many watts different types of air conditioners use.

Window Air Conditioner Watt Usage

Window air conditioners are designed to cool one or two rooms. They’re ideal for cooling spaces that are 200 to 800 square feet in size. The smallest window air conditioners use about 500 watts. The highest capacity of window air conditioners consumes about 900 watts of power.

Central Air Conditioning System Watt Usage in Fan-Only Mode

When operating with just the fan on, a central air conditioning system uses about 750 watts of power. You may want to set your thermostat to the fan function overnight. The fan circulates the cooler air through your home. The air also passes through the filter, which could give your home’s indoor air quality a boost.

Central Air Conditioning System Watt Usage in Cooling Mode

Central air conditioners operating in the cooling mode use 3,000 to 4,000 watts of power. They use this electricity to power the condenser and compressor, the outdoor and indoor fans, and other critical parts. Your air conditioning system’s owner’s manual should explain exactly how many watts of power your model of cooling system uses. Check this information when comparing which replacement model could save you the most money.
