What size air conditioner do I need for a 3000 square foot house?
“…an air conditioner generally needs 20 BTU for each square foot of living space.” We need to convert BTU to tonnage….Tonnage Table.
| Area (Square Feet): | BTU | Tonnage |
|---|---|---|
| 2,700 sq ft | 54,000 BTU | 4.5 Tons |
| 3,000 sq ft | 60,000 BTU | 5 Tons |
| 3,300 sq ft | 66,000 BTU | 5.5 Tons |
| 3,600 sq ft | 72,000 BTU | 6 Tons |
Do I need 2 ton or 3 ton AC?
If you live in a home that’s about 1,800 square feet, has standard 8-foot ceilings, average sun exposure, and it’s a cold climate, you’ll probably need a 3-ton, (36,000 BTUs) unit. Change that to a hot climate, and you’ll need to upsize that to a 3.5-ton (42,000 BTUs) unit. Assuming all variables remain the same.
How many tons is 1700 square feet?
The size (cooling capacity) of your air conditioner is determined by the amount of Btu (British thermal unit) and the Tonnage (12.000 Btu = 1 Ton)….Typical Tonnage by SQFT.
| SQFT | Ton |
|---|---|
| 750 to 1,000 | 2 |
| 1,050 to 1,400 | 2.5 |
| 1,450 to 1,700 | 3 |
| 1,750 to 1,900 | 3.5 |
What’s the difference between 14 SEER and 16 SEER AC?
One difference that you may find between 14 SEER and 16 SEER units is that the 14 SEER units generally have a single-stage compressor while the 16 SEER units often have a two-stage compressor. Not only does the two-stage compressor make your HVAC unit more energy-efficient, it also allows for longer run-times.
How many tons AC do I need for 1000 square feet?
DIY Calculations
| Square Footage | BTUs per hour | AC Unit Tonnage |
|---|---|---|
| 450 to 550 | 12,000 | 1 Ton |
| 550 to 700 | 14,000 | 1.5 Tons |
| 700 to 1,000 | 18,000 | 1.5 Tons |
| 1,000 to 1,200 | 21,000 | 2 Tons |
Is a 2 ton AC big enough?
Pro Tip: as a rule of thumb, the maximum AC unit size you need to install should not be more than 15% more than the BTU’s you need to cool your house. This means that if your house requires a 24,000 BTU unit (2 tons), you should not install one that is larger than 30,000 BTU’s (3 tons) to maintain energy efficiency.
What happens if you oversize an air conditioner?
An oversized HVAC unit can make your home’s inside temperature uncomfortable. An HVAC system with excess capacity can heat or cool your home faster, but that speed often results in a couple of other issues. As a result, you could end up with a number of hot or cold spots throughout your home.
Is 2.5 ton AC big enough?
According to this common but somewhat inaccurate method, you need 1 ton of air cooling capacity for every so many square feet of living space. While there’s some dispute over the exact amount, an often-used amount is 600 square feet. A 2.5-ton unit, then, theoretically would fit a 1,500-square-foot home.
