$89 for the first hour of diagnostic service. Residential AC, heat pumps, mini splits and commercial rooftop units.
Blowing warm air
Often a refrigerant, capacitor, compressor or outdoor fan problem.
Ice on the coil or lines
Usually restricted airflow or a refrigerant issue. Turn the system off and let it thaw.
AC won't turn on
Tripped breakers, failed contactors, blown fuses, thermostat or control board problems.
Water leaking indoors
A clogged condensate drain or damaged drain pan can let water back up.
Loud or unusual noises
Buzzing, grinding, rattling or squealing from the indoor blower or the outdoor unit.
Weak airflow or short-cycling
A system that barely pushes air, or turns on and off quickly, needs a closer look.
