Diagnosing and fixing air conditioners that won't cool, freeze up, leak, make noise or keep shutting off — refrigerant, capacitors, fans, compressors and controls.

Repairing and replacing gas and electric furnaces — ignitors, flame sensors, blowers, heat exchangers and controls — and installing new ones.

Replacing the whole heating and cooling system — sizing it to the home, installing the furnace or air handler, AC or heat pump, and thermostat.

Yearly tune-ups for heating and cooling — cleaning, checking and adjusting the system — usually with priority service and repair discounts.
