What size air conditioner with heat will you need for 900 square feet?

For a 900-square-foot home, you'll need an air conditioner with a cooling capacity of 9,000 BTUs (British Thermal Units). This will provide enough cooling power to keep your home comfortable during hot weather.

To determine the size of air conditioner you need, you'll need to consider the square footage of your home, as well as the climate in which you live. In general, you'll need more cooling power for a home in a warmer climate than you will for a home in a cooler climate.

Here is a general guide to help you select the right size air conditioner for your home:

- Up to 400 square feet: 5,000 BTU

- 401- 700 square feet: 7,000 BTU

- 701 - 1000 square feet: 9,000 BTU

- 1001- 1300 square feet: 12,000 BTU

- 1301 - 1700 square feet: 15,000 BTU

- 1701- 2200 square feet: 18,000 BTU

- Over 2200 square feet: 24,000 BTU

In addition to cooling capacity, you'll also need to consider the energy efficiency of the air conditioner. The higher the energy efficiency rating, the less energy the air conditioner will use to operate. This can save you money on your utility bills in the long run.

Look for an air conditioner with an Energy Star rating. Energy Star-rated air conditioners meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA).

Also, consider the features that are important to you, such as a programmable thermostat, a remote control, and a sleep mode. You can also choose an air conditioner that is compatible with a smart home system, which allows you to control the air conditioner from your smartphone or other device.

Finally, be sure to have your air conditioner installed by a qualified technician. This will ensure that the air conditioner is installed properly and is operating safely.
