How to Find the Tonnage

The best way to find out the size of your air conditioner or heat pump is by first locating its model number. The model number is located on a metal tag on the outdoor cooling unit (condenser), OR if you have another proposal from that model number.

Once you find the model number, read it and look for a number that is divisible by 12. We can use this number to calculate the size of your system. For instance if the model number is TTB736A100A1, you will notice that there is a 36 embedded in the model number. You can divide that number by 12 and the result is 3. This means your air conditioner / heat pump is 3 tons.

Please update the Equipment Size in the dropdown menu above. If you were not able to determine the tonnage, please proceed below.

What if I don’t know my equipment size?

An air conditioner’s size is measured in tons. This refers to its cooling capacity, not its physical weight. If you don’t know your AC’s tonnage, click on the Equipment Size dropdown menu and select “I don’t know”. Instructions on how to find your AC’s tonnage will appear.

Do you guarantee that the price I see in my estimate is the exact price I will pay for my new air conditioner?

Honesty and integrity is fundamental to our business philosophy. We will install the equipment we quoted for what we quoted assuming the information you provided is correct (see below). We can offer options and promise you we won’t try to sell you something you don’t want or need, nor will we resort to high pressure sales tactics.

What if I want to upgrade to a higher efficiency air conditioner?
