Install or Service?

AIR GT concentrates on installation of the new furnace. The house heat and cooling load is determined for each installation. Raised ranches are one of the specialties AIR GT works on. To put a new furnace into a 70's, 80's or 90's home is one of the main goals. A new central air is a great addition as well. Whether it be a first time install or to replace an old one.  Of course bungalows, back splits, side splits, 2-storey and standard ranch styles. Ideal sizes of homes AIR GT does range from 800 sq ft to 2000 sq ft.

Is the existing furnace in the home questionable? A little bit older? If it is 15 years or older pilot light equipped model it may be time for it to go. A mid efficient of the same age can be changed as well. A high efficiency furnace 20 years or older is also worth considering for replacement. Central air which is over 15 years old is really worth looking at to see if it is time to change. Most furnaces put in the types of homes shown above will be 45,000 BTU or 70,000 BTU & most central air will be either 1.5 or 2 ton. 

Installation of Heat and Air Conditioning

  • determine size of equipment for the home; check aspects of job for upcoming installation 
  • disconnect and remove old furnace and dispose of it
  • mount new furnace and attach all ductwork including to the Air Conditioning coil
  • connect venting, gas piping, electrical, venting, condensate and thermostat
  • set up the furnace controls, blower and thermostat for correct operation
  • remove previous A/C unit if applicable outside and dispose
  • mount new A/C condensing unit outside and connect refrigerant tubing
  • connect electrical and control wiring and additional condensate
  • leak check, evaculate, charge, test run
  • fill in forms and register the factory warranty on-line


Determining Replacement or Service

  • identify concerns about the existing furnace 
  • check heat exchanger, flame pattern, venting, operation, CO
  • consider the future with this model and age of furnace
  • configuration, dimensions of the furnace
  • check A/C age, operation, for leaks, problems
  • home dimensions for equipment sizing 
  • existing equipment efficiency vs new; determine if change to be made
  • heating check-out: check limit, thermo, flame sense, pilot of igniter, limit, burner ignition, ventor, switches, controls, connections, flame, operation, heat exchanger(s), temp rise, filter, blower, motor, A-coil
  • air conditioning check-out: check refrigerant pressures, superheat or sub-cooling, RA temp, electrical, controls, connections, cleanliness of coils, operation, air flow system delivery
  • thermostat: check operation, set-up and batteries
