What size AC do I need for 500 square feet?
10,000 BTU
The equation for ‘sq ft to BTU’ is quite simple – multiply the sq ft with 20. That means that a 500 sq ft room needs a 10,000 BTU air conditioner. Of course, do make sure to buy an AC unit that is a bit stronger if you have high ceilings, live in a hot climate, and have an above-average sun in those rooms.
Can one AC unit cool a whole house?
Properly sized and installed, a split system—one with indoor and outdoor equipment—can keep an entire house nicely chilled on the hottest days, and do so far more efficiently than a battalion of window units. Read this guide to walk through the factors that affect how these systems function.
Can a small AC unit cool a large room?
Homeowners can use a portable air conditioner to cool more space when the openings are larger through the house. This means areas where the living and dining rooms have an opening large enough to view both rooms. A den leading into the dining area is a good example of where a portable unit can keep both rooms cool.
How many square feet will a 1 1 2 ton AC unit cool?
The industry standard for central air conditioning units is that they begin from a minimum size of 1.5 tons and get larger in half-ton sizes. So, 1.5-ton, 2-ton, 2.5-ton, and so on. And each half-ton will cool an estimated 750 to 1,000 square feet of space.
How many BTU is 550 square feet?
12,000 BTUs
450 – 550 sq. feet: 12,000 BTUs. 550 – 700 sq. feet: 14,000 BTUs.
How many BTUs do I need for a 500 square foot room?
‘How many BTUs for 500 sq ft for adequate cooling? ‘ Simple answer: 10,000 BTU to 12,000 BTU. We get 10,000 BTU by using the AC rule of thumb sizing method (’20 BTU per sq ft of living space’; hence 20×500 sq ft = 10,000 BTU).
How big of a AC unit do I need?
As a rule of thumb, an air conditioner needs 20 Btu for each square foot of living space. But other considerations, such as the ceiling height and the size of your windows and doorways, might call for more cooling power. To measure your room, multiply the length by the width.
Can a window unit cool a whole apartment?
Window units are (relatively) affordable, space-saving, and easy to install and uninstall. If you have multiple rooms, you may have to install one unit for each room for even cooling. These units usually require a support bracket installed outside the window for security.
Can an air conditioner cool multiple rooms?
Fact: cold air hates to travel. That means, that when you move to a nearby room, the flow of cool air will stop at the doorway. So, avoid trying to cool multiple rooms using just one window air conditioner.
How many square feet will a 1 ton AC unit cool?
A common rule of thumb is to assume that a standard HVAC unit can cool around 400 square feet of residential space per ton of cooling capacity. When calculating the power you need to cool your home, you can assign 12,000BTUs that need to be cooled per 400 square feet of property.
What happens if my AC unit is undersized?
Undersized air conditioners will struggle to ever get the room cool enough and therefore will fail to go through healthy on and off cycles. This extra wear and tear will lessen the life of your ac and cost you more in repairs.
Can an AC unit be too big?
When an AC system is too big, it won’t run regular cycles. As a result, the cycles will not be long enough to remove humidity from the air (which is a big deal living in Florida). Generally, it takes a cycle of 20 to 30 minutes to cool and dehumidify the air.
Is it better to undersize or oversize an AC?
While an AC’s capacity typically matches its energy usage, an undersized air conditioner will use more power simply because it is likely to run continuously, barely stopping for breath.
Why an oversized air conditioner is a bad idea?
Again, because oversized HVAC units blast your home with cool air instead of cooling it down gradually, the temperature swings prompt your HVAC system to start up and shut down in rapid succession-a condition commonly known as “short cycling.” Short cycling can wreak havoc on your HVAC system if left unchecked.
How do I know if my AC unit is big enough for my house?
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.
How do you know if your AC is too big?
4 Signs Your AC System Is Too Big for Your Home

What SEER rating should I buy?
For most homeowners, opting for a unit with a SEER between 15 and 18 is a good choice because it’s a balance between the money you’ll spend for the unit and the amount you’ll save on utility costs.
Does a higher SEER cool better?
It’s calculated by dividing the cooling output for a system by the energy used to create it. Most industry experts compare a SEER rating to a car’s fuel efficiency. The higher the SEER, the more efficient the cooling system should be. Similarly, cars with higher miles-per-gallon ratios go further with less fuel.
How many seers do I need for my house?
Since January 2006, all residential air conditioners sold in the United States must have a SEER of at least 13. ENERGY STAR qualified central air conditioners must have a SEER of at least 14. By upgrading from SEER 9 to SEER 14, you can reduce your energy consumption by more than 35%.
