Cooling Equipment Air conditioning is another major contributor to your annual energy bill.
Air conditioners operate just like heat pumps in that they move heat from the inside to the outside.
An air conditioner s efficiency is determined by its mechanical design with newer models being more economical than older ones. Besides age, air conditioner efficiencies are affected by how well they ve been maintained, so it is a good idea to take a look at the cooling unit of a prospective rental. The outside condenser should be sitting on a level surface, free of foliage that may block air flowing into it. Check the finned heat exchanger that surrounds the condenser to make sure the fins are aligned and clean. What you want is equipment that is in good shape with unobstructed airflow.
