How big of house will a 3.5 air conditioner cool?

The cooling capacity of an air conditioner is measured in British Thermal Units (BTUs) per hour. A 3.5-ton air conditioner has a cooling capacity of 3.5 x 12,000 = 42,000 BTUs per hour.

The size of the house that a 3.5-ton air conditioner can cool depends on several factors, including:

* The climate in which the house is located

* The amount of insulation in the house

* The number of windows and doors in the house

* The size of the rooms in the house

In general, a 3.5-ton air conditioner can cool a house up to 1,500 square feet in a moderate climate. However, if the house is located in a hot climate, or if it is poorly insulated, the air conditioner may not be able to cool the house adequately.

It is important to consult with a qualified HVAC technician to determine the correct size air conditioner for your home.
