Air Conditioner Sizing & Buying Guide Abt
Air conditioners cool your home and sizing the air conditioner to the room size is essential for proper efficiency and cooling capacity. Air conditioners are rated in BTUs and the BTU rating determines the cooling capacity in the square footage of the living area to be cooled. Generally, you need 20 BTU for every square foot of space in your home. The chart below can guide your BTU choice: The larger your home, the higher BTU you'll need to support your comfort. One of the most accurate ways to measure the right size AC for your home is with a Manual J calculation. Manual J calculation Air conditioner size doesn't refer to the unit's measurements, but rather its cooling capacity. Air conditioners are measured in British thermal units (BTUs) or British thermal units per Hour (BTUh). One ton of air conditioning removes 12,000 BTUs of heat per hour. Put another way, an air conditioner needs 20 BTU to control each square foot. What do you need? House Location (use map below) House Square Footage Easy To Use A/C Size Selection Tool: Check the color coded map above and confirm the zone your home is in.

Then, multiply the square footage by 25-50 btu/hr.sqft according to the application to obtain the cooling capacity needed. Finally, match the air conditioner size with the required cooling capacity. Following are a series of air conditioner sizing charts for different applications from bedrooms and living rooms to apartments and mobile homes. Residential air conditioners usually range from 1.5 to 5 tons (or, 18,000 - 60,000 BTUh). Anything with larger cooling capacity would be considered light commercial. Tonnage ratings are typically expressed in increments of .5 tons, so residential air conditioners are usually rated as 1.5, 2, 2.5, 3, 3.5, 4, 4.5 or 5 ton units.

(Tonnage Per Square Foot) Simple answer: You need 0.0016 tons of AC per square foot. In short, if you're looking to cool down a 600 sq ft area, you would need: AC Capacity = 600 sq ft * 0.0016 tons/sq ft = 1 Ton In general, for every 600 sq ft, you need 1 ton of AC. This is a general estimate. AC Tonnage Calculator accurately estimates the proper Central AC size in TONs & BTUs, as well as the cost to install your Central Air system in different climate zones, based on your house size & AC SEER rating, conditioned space size, heat load / loss, & other parameters. The size of your AC will determine the replacement costs & energy usage.
