TUCSON AIR CONDITIONING CONTRACTORS (This information is for the convience of my clients. I do not recommend one service over another. Nor am I responsible for the quality of service provided by these companies.)
Some factors to consider when purchasing a cooling/heating unit:
*Size-unit's capacity * Air filtering & cleaning features *Convenient controls *Weight *Noise levels *Energy efficiency
Higher efficiency units will cost more than less efficient units but lower energy bills over time will off-set the costs.
Remember, you are not just dealing with air temperature, this is the air you are breathing!
