An important part of the reliability, efficiency, and performance of your new AC in Portland comes from carefully checking supporting equipment such as ductwork and control systems. When the air conditioner unit is working with the right static and dynamic air pressures, refrigerant levels, and thermostats, it can work less to accomplish more in keeping your home cool. Even verifying that the outside compressor unit AC installation location is right, with proper air circulation, can make a big difference.
