Tino's Heating & Cooling - Phoenix's Licensed HVAC Repair

Yes, that's a common issue here in Phoenix. The intense heat can cause the reversing valve—which switches your system between heating and cooling—to fail or get stuck. We specialize in diagnosing and repairing reversing valve problems to restore your heat pump's proper cooling function quickly and efficiently.

Absolutely. Incorrect thermostat calibration is a frequent culprit, especially with older units. A miscalibrated thermostat misreads your home's temperature, causing the system to cycle incorrectly. We provide precise thermostat calibration, repair, or replacement services to ensure your HVAC system responds accurately to Phoenix's high temperatures, improving comfort and efficiency.

Our preventative maintenance service is specifically designed for the harsh Phoenix climate. We perform a thorough check, including inspecting components like the reversing valve for early signs of wear, testing thermostat accuracy, cleaning coils, and ensuring optimal refrigerant levels. This proactive care helps prevent sudden breakdowns during peak summer heat, extends your system's lifespan, and maintains its energy efficiency.
