Central Air Conditioning

      37200paA Residential Split System Central Air Conditioning system keeps your entire home cool in the warmer months, while it helps lower indoor humidity levels.

      The system includes a compressor, a fan, condenser coil, evaporator coil, and a refrigerant. It extracts heat from indoor air and transfers it outside, leaving the cooled indoor air to be recirculated.

     The efficiency of central air conditioning systems is rated using SEER ratios.

     A central air conditioning system uses electricity as its power source, and requires:

  • An outdoor section (the condensing unit).
  • A matching indoor gas or oil furnace with coil, or air handler.
  • Ductwork to transfer the cooled air throughout the home.

    NHM offers a wide variety of Residential Split System Central Air Conditioning systems in different sizes and efficiencies.            

 

 

Electric Heat Pumps

A Residential Split System Heat Pump is a year 'round comfort system. In the summer it draws heat out of your home to keep it cool, and in the winter it draws heat from outside air into your home to keep it warm. Many heat pump installations have a booster electrical resistance heater that automatically supplements heat brought in from the outside. Outside air always has heat in it — even at very low outdoor temperatures.

     Like a central air conditioning system, it includes a compressor, a fan, outdoor coil, indoor coil, and a refrigerant.37200pa

    The efficiency of Heat Pumps is rated using SEER (for cooling efficiency) and HSPF (for heating efficiency).

    A Heat Pump uses electricity as its power source, and requires:

  • An outdoor Heat Pump section.
  • A matching indoor gas (natural or propane) or oil furnace with coil, or air handler.
  • Ductwork to transfer the heated or cooled air throughout the home.
