Experienced HVAC Services in PHOENIX, AZ 85037 - Oscars AC

Absolutely. In our Phoenix climate, thermostats can drift out of calibration due to factors like direct sunlight on the unit or normal wear. This leads to inaccurate temperature readings, causing your AC to short cycle or run longer than needed, creating uneven temperatures and higher bills. Our technicians can perform a precise calibration or recommend a modern, programmable thermostat better suited for Arizona homes to restore even cooling and improve efficiency.

A faulty reversing valve, a common issue here, often shows up as your system being stuck in one mode. In summer, it might only blow hot air, and in winter, only cold air. You may also hear a faint hissing sound from the outdoor unit. Since this valve is crucial for switching between heating and cooling, prompt repair is essential. We can diagnose valve issues and perform the necessary repair or replacement to get your heat pump functioning correctly for year-round Phoenix comfort.

Preventive maintenance is key in our harsh climate. Our seasonal tune-ups include checking thermostat accuracy, testing heat pump components like the reversing valve for proper operation, cleaning coils, and ensuring refrigerant levels are correct. This proactive service catches small issues before they lead to system failures during a Phoenix heatwave or cold snap, saving you money on repairs and energy costs while extending the life of your equipment.
