# How do I know what size heat pump I need?

While inside your home we first consider the square footage of the room/area and using this guide determine which sized heat pump will suit that space:
1. 9,000 BTU – ~250 sq. ft to ~450 sq. ft.
2. 12,000 BTU – ~550 sq. ft to ~800 sq. ft.
3. 15,000 BTU – ~750 sq. ft to ~1100 sq. ft.
4. 18,000 BTU – ~850 sq. ft to ~1250 sq. ft.

Considering this, how do I calculate what size heat pump I need?

Calculate the square footage of the room by multiplying its length by its width. Multiply the area by 25. This answer is the approximate British Thermal Unit (BTU) output you need for that room, which is how ductless heat pumps are sized.

Secondly, what size heat pump do I need for 1600 sq ft? Sizing a Heat Pump Typical home sizes range from 1 1/2- to 5-ton capacity. Though sizing a system should be handled by a professional, you can get a rough idea of size by figuring about 400 square feet of living space per ton in older houses, so, a 1,600-square-foot house would normally require about a 4-ton system.

Moreover, how many square feet does a 3 ton heat pump cover?

Air Conditioning Square Footage Range by Climate Zone

ZONE 1 ZONE 2
2 Tons 901-1200 sf 951 - 1250 sf
2.5 Tons 1201 - 1500 sf 1251 - 1550 sf
3 Tons 1501 - 1800 sf 1501 - 1850 sf
3.5 Tons 1801 - 2100 sf 1851 - 2150 sf

What size heat pump do I need for a 1500 square foot house?

STEP 1: Determine how many BTUs of heating and tons of AC you need

House Square Footage BTUs Needed
700 – 1,000 18,000
1,000 – 1,200 21,000
1,200 – 1,400 23,000
1,400 – 1,500 24,000
