Air Conditioner Installation FAQ’s

What air conditioner size do I need?

What is an inverter air conditioner?

An inverter air conditioner is a more energy-efficient type of air conditioner. Unlike other types, inverter air conditioners bring you to the desired temperature then work at a constant, slower pace to keep the temperature at that level. This is much more efficient than jumping up-and-down around your target temperature.

How much is an air conditioner?

Pricing varies depending on size, brand, and efficiency. Pricing starts at $2500.00 and can reach $7000.00

Where to install an air conditioner?

The best place to install an air conditioner is on the cooler side of your home that is out of direct sunlight. You will generally meet both of those criteria on the North side of the home. This allows the unit to work more efficiently.
