Some frost in winter is normal. A unit that stays iced points to airflow, refrigerant or defrost-control problems.
Blinking lights and error codes on Mitsubishi, Daikin, Fujitsu and other ductless systems, traced to the sensor, board or refrigerant issue behind them.
Units that start and stop, rattle, hum or trip the breaker are checked for electrical, airflow and sizing problems.
Clogged condensate lines and drain pumps cleared and tested before water damages the wall.
If the system is not worth fixing, you get the reasons in writing and options to compare, not pressure.
South County summers run hotter than the rest of the South Bay, so Morgan Hill heat pumps put in long cooling seasons. Worn parts tend to show up during the first hot week.
Fan motors, capacitors, contactors and reversing valves on condensers in side yards and on pads, checked under load rather than guessed at.
Attic and crawlspace air handlers in tract homes lose capacity to dirty coils, crushed flex duct and blocked returns. HAXX measures airflow before blaming refrigerant.
HAXX is a licensed electrical contractor too, so tripping breakers, burnt disconnects and thermostat wiring are fixed on the same call.
