FAQ’S

What is a SEER?

Air conditioning equipment is rated by the Seasonal Energy Efficiency Rating, or SEER. The higher the SEER rating, the more efficient the unit.

What does HSPF stand for?

Heat pumps in heating mode are rated by the Heating Seasonal Performance Factor, or HSPF. The higher the HSPF rating, the more efficient the unit.

What does AFUE stand for?

Gas furnaces are rated according to their Annual Fuel Utilization Efficiency, or AFUE. The higher the AFUE rating, the more efficient the unit.

Should outdoor units be covered in winter?

No. Heat pumps operate year-round and should never be covered. Similarly, air conditioners that operate seasonally are built to withstand an outdoor environment and should not be covered.

Should a thermostat be set to “auto” or “on”?

Preferably auto. That way, the fan operates only when the temperature requires it. This is the most used and the most efficient setting. However, there are advantages to using the “on” setting. Air is constantly filtered through the unit’s air filter, and the constantly circulating air results in an even temperature throughout the house.

Can shrubs or flowers be planted around an outdoor unit?

Sometimes… small shrubs and plants should be no closer than 18 inches to the unit. No large trees, bushes, or plants of any kind should obstruct the air flow of the unit. Air flow obstruction will cause excessive heat load on the system resulting in a premature failure or diminished system capacity.

If an outdoor unit needs replacing, should the indoor unit be replaced too?

Yes. Air conditioning and heating units are designed to operate as a complete, matched system. The efficiency rating and equipment capacity is based on the entire system. Replacing the entire system ensures the system will function correctly and be efficient.

How do I know what size unit our house needs?

Size of the house, climate, the number and type of windows installed, insulation, and even the number of people living in the house are some of the many factors used in determining which system should be installed.

What is the difference between a split system and a package unit?

A split system uses an indoor air handler and outdoor condensing unit for a complete system. A package unit has all components in one package and is self contained.
