  heating and cooling questions.

  How often should filters be cleaned or replaced?

  Typically, filters should be cleaned or replaced once a month. Some units are
  equipped with permanent filters. They can be cleaned according to the
  instructions supplied. Disposable filters should be replaced with filters of the
  same type and size as the original filter.

  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 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. 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.) 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?

  Just ask us, we 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.
