Commercial heating and air conditioning

What is commercial air conditioning?

Commercial AC units usually combine the heating and cooling units in a single rooftop package, which prevents the noise it causes from interfering with occupants’ work. Keeping the package on the roof also helps the business conserve physical space.

Residential heating and air conditioning

Air conditioning, often abbreviated as A/C or AC, is the process of removing heat and controlling the humidity of air in an enclosed space to achieve a more comfortable interior environment by use of powered air conditioners or a variety of other methods, including passive cooling and ventilative cooling.
