What are load calculations for an HVAC system?

The HVAC load calculation shows you the exact amount of BTUs a certain space requires for sufficient heating and cooling. It identifies the square footage of the room to determine the capacity—BTUs per hour—needed to reach the desired indoor temperature.

What is the difference between 1.5 ton and 2-ton AC?

-> 1-ton AC – Room size less than or equal to 130 sq. ft. -> 1.5-ton AC – Rooms between 130 sq. -> 2-ton AC – Rooms bigger than 150 sq.

How many ton is my AC?

Simply divide the BTUs by 12,000 to calculate the tonnage of your unit. For example, if your air conditioner is 36,000 BTUs, you have a 3-ton unit. Some manufacturers bury tonnage or BTU information in their model numbers. Look for an even, two-digit number between 18 and 60.

What size heat pump do I need for 1000 square feet?

For every sq ft of living space, you need about 30 BTU of heating output. That means, for example, that for a 1,000 sq ft home, you would require a 30,000 BTU heat pump (that’s a 2.5-ton heat pump).

How many BTUs do I need to cool 1000 square feet?

What size HVAC unit should I buy?

Rule of Thumb — The maximum size unit you should buy would be 15\% over the BTUs you need for cooling and 40\% of the BTUs for heating. The max for heat pumps is 25\%, since it handles both cooling and heating. Need more advice? Contact your local Trane Comfort Specialist™ to learn more about your heating and cooling options.

How many BTUs do I need for my air conditioner?
