In a central heating unit why does heating element keep coming on when the heater is not on?
Sounds like the thermostat is set too high so the unit is calling for heat... If the thermostat is set normally then the unit has a fault. Repairing an air conditioning unit is not a Do-It-Yourself job. The best advice anyone should give you is to call a licensed Heating Ventilation and Air Conditioning (HVAC) technician to check the unit for you. If it is faulty it can then be decided if it is worth spending money to repair it or if it makes more sense to replace it with a new one.
How does the 2-stage high efficiency home central air conditioner operate?
The way the unit operates depends on the type of thermostat installed. Normally, they use a two stage thermostat. In this case, when the thermostat senses a need for cooling the condensing unit starts in low speed. If the temperature at the thermostat does not drop fast enough, the condensing unit is switched to high speed. The timing of the changing of speeds varies with the thermostat and unit.
