When getting an AC size is extremely important! An undersized air conditioner will struggle to cool your home. It’ll run longer cycles than it should since the square footage it’s trying to cool is simply too large for its output capacity. On the other hand, an oversized unit will short cycle, meaning it’ll turn on and off in short bursts. Here are 5 Steps to calculating how large of unit you need:

Step 1: Calculate the square footage of the area to be cooled. Figure out if the space will be divided into zones that are cooled by separate air conditioning units. Keep these measurements separate.
Step 2: Next, multiply the square footage obtained for each area by 25.
Step 3: Then, add 400 for each person who works in that particular area.
Step 4: For each window, add 1,000.
Step 5: The number gained from steps 1 to 4 represent the minimum BTUs that the air conditioning unit should provide.

These calculations are for rooms with an 8-foot ceiling. However, higher ceilings require a greater number of BTUs.

Electric AC uses one type of power, electricity. While Gas uses a combination of gas and electricity. If your unsure which one you have call us we may be able to walk you through how to check what your setup is.

A package HVAC unit combines multiple units, such as an air conditioner and heater, into a single unit. The unit is usually placed outside. Split systems, on the other hand, divide each system into its own unit, so your heater and air conditioner are separate.
