What Size Air Conditioner Do I Really Need?

Air Conditioner Size

Central air conditioners come in different sizes and are measured in “tons”. A “ton” is a measure of an air conditioner’s ability to cool. One ton is the ability of the air conditioner to cool 12,000 BTUs (British Thermal Unit) in an hour.

The size of the AC is one of the most important factors, but these questions are pretty technical if you don’t have prior HVAC knowledge. In our upcoming blog post, we will provide you a quick guide of how to determine what size Carrier or York central air conditioner you need for your home.

The Air Conditioner Size is an important factor to consider. It is very important to install the properly sized A/C in your home for a variety of reasons as units of the wrong size will increase energy bills and decrease your comfort.

A right-sized York or Carrier air conditioner will run a proper full cycle and ensure your home stays cooler longer. This means that a properly sized air conditioner unit will use energy more effectively and will lower your energy bills, and keep your home at a more consistent temperature. An over-sized AC system will turn on quickly, cool your home rapidly and then shut off. This will interrupt the cooling cycle that your unit was designed for and force your unit to turn on and off more rapidly, will defeat the purpose of its high-efficiency design and increase your electricity bill. An undersized system will not effectively cool your entire home. It will run continuously, waste energy, and cost you more.

Carrier, York, American Standard, Lennox, and Goodman air conditioners are available in different sizes for different needs for cooling.

Size is a key factor to performance and efficiency of your HVAC system and depends on:

  • Total volume of your home’s living space, not just the square footage
  • Area of sun-exposed exterior walls
  • Amount of sunshine on your home
  • Age of your home
  • Degree of air sealing
  • Existing ventilation system and ductwork

Understanding Size: What Do TON and SEER mean?

Air conditioner sizes are rated in tons of cooling capacity. One ton of cooling is equal to 12,000 BTU’s (British thermal units) per hour.

While two air conditioners be the same tonnage, they could be completely different in terms of their energy efficiency or Seasonal Energy Efficiency Ratio(SEER) . After you have found the right tonnage-size to cool your home, you’ll want to look over which ones have the best SEER rating. The higher the rating, the less energy it will use. Systems that are Energy Star qualified range between 12 and 23 SEER.
