Find the Perfect AC Tonnage for Your Property in 60 Seconds

Buying the wrong size air conditioner online is an expensive mistake. If the system is too small, it won't keep your property cool during peak summer heat. If it’s too large, it will constantly cycle on and off, short-circuiting the compressor and increasing your energy bills.

At Xpress Supply, we want to make sure you get the exact equipment you need. Our Smart AC Sizing Calculator analyzes your square footage, property type, and layout to match you with the correct tonnage and high-efficiency options available in our inventory.

How We Calculate Your Ideal AC System Size

To ensure accurate sizing for your house, condo, or light commercial project, our calculation engine factors in three critical data points:

01

Total Square Footage

The foundational metric used to determine the total BTUs (British Thermal Units) required to cool your living space efficiently

02

Property Type & Insulation

A standalone home requires a different thermal load calculation than a modern condo with shared walls or a space with high vaulted ceilings.

03

The Texas Climate Standard

Our tool is calibrated for high-temperature zones, ensuring your selected system has enough power to manage intense heat and humidity without straining.
