The amount of watts used by a central air conditioner can vary depending on several factors, including:

Size (tonnage): This is the primary factor, with larger units requiring more power. Typically, each ton of cooling capacity roughly translates to 1,000 watts of power consumption. So, a 3-ton central air conditioner would use approximately 3,000 watts.

Efficiency: The efficiency rating of your AC unit, measured by the SEER (Seasonal Energy Efficiency Ratio) rating, plays a crucial role. Higher SEER ratings indicate better efficiency, meaning they use less power to achieve the same cooling output.

Operating conditions: The outside temperature, humidity, and desired indoor temperature all affect how much power your AC needs to operate.

Here’s a general breakdown of central AC power consumption:

  • Small (up to 1.5 tons): 1,500 – 2,500 watts
  • Medium (2-3 tons): 2,500 – 4,000 watts
  • Large (4+ tons): 4,000+ watts

However, it’s important to remember that these are just estimates. The actual power consumption of your AC unit may differ depending on the factors mentioned above. If your home has tall ceilings, two stories, many large windows, single-pane windows, poor insulation, or a lot of direct sunlight exposure, you may need an air conditioner with more capacity.
