HVAC FAQ

What do rating numbers mean?

The U.S. government requires an efficiency rating of all air conditioning and heating equipment. The rating reflects the percentage of energy used efficiently, with a high rating indicating high-efficiency. The next two topics address this issue in greater detail.

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 pump equipment is 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?

Yes. However, we recommend that plants be no closer than 18 inches to the unit. This allows for plenty of room for air circulation in and out of the unit. Without this room for air circulation, the unit could overheat, resulting in a premature need for service.

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 is based on the entire system. Replacing the entire system ensures the system will be reliable and efficient.

How do I know what size unit our house needs?

A Precision Air estimator will consider many factors before making a recommendation. Factors like size of the house, climate, the number and type of windows installed, insulation, and even the number of people living in the house.

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

A split system uses indoor and outdoor components to provide a complete home comfort system. A package unit or self-contained unit requires no external coils, air handlers, or heating units.

I am new homeowner and had never got a heater inspection/tune-up... I scheduled one with Precision and had a great experience. My technician Steve was timely, professional, (funny), and honest. He showed me a few ways to increase the life of my system while also improving the quality of my air and lowering my utility bill. I recommend Precision Air for sure.

I hired these guys to service my old boiler and radiator heating system. The unit was made in 1987 so I was expecting to have to get a new unit. While it does need to be replaced eventually I was happy that they didn't make me feel like I had to. They just serviced it and gave me a recommendation for a new one. They seem like honest guys. Thanks.
