Equipment Sizing


Heating and cooling replacement equipment is estimated by considering the type, size and approximate age of your home, the estimated heat gain/heat loss, the estimated insulation factor, and assumes average lighting, occupancy loads and having an existing adequately sized, non-leaking air duct delivery system.

For the Northern Illinois region: At 0°F outside temperature the Heating system should provide an average inside temperature of 70°F.  When the temperature hits 95°F outside, the Air Conditioning system should provide an average temperature of 75°F to 78°F inside.  There can and will be temperature difference between lower and upper floors levels with both single or two zone systems and this temperature difference is normal.
