HVAC Q&A.

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?
There are. special names for the efficiency ratings of various types of equipment. 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?
There are special names for the efficiency ratings of varying types of equipment. Heat pump equipment in the EI(. #759171 heating mode 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?
There are special names for the efficiency ratings of various types of equipment. 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. If you have a heat pump it is designed to 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”?
That is a personal preference. . in “auto” 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, but there are some exceptions… 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. There is also refrigerant changes and federal regulations in new equipment to consider (R-410A) that require not only the indoor and outdoor unit but the refrigerant lines as well. That being said some manufactures are still producing “Dry Charged” (R-22) outdoor units that can be matched up to your existing indoor unit. With the phasing out of R-22 and the increased cost of that type of refrigerant (Freon) there are better options.
