How do I know what size heat pump I need?
- 9,000 BTU – ~250 sq. ft to ~450 sq. ft.
- 12,000 BTU – ~550 sq. ft to ~800 sq. ft.
- 15,000 BTU – ~750 sq. ft to ~1100 sq. ft.
- 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|
