HVAC Repair Tucson AZ | Call Aqua Heating & Cooling

This is called short cycling, a common issue in our hot climate that strains your system and increases bills. It's often caused by an oversized unit, low refrigerant, a dirty air filter, or a faulty thermostat. Our technicians will perform a comprehensive diagnostic to pinpoint the exact cause. We then provide the necessary repair, whether it's a refrigerant recharge, component replacement, or system calibration, to restore proper, energy-efficient operation and protect your AC from premature wear.

It very well could be. The reversing valve is the component that changes the flow of refrigerant to switch modes. In Tucson's demanding climate, these valves can become stuck due to wear, debris, or electrical issues. If your system is stuck in one mode, our experts at Aqua Heating & Cooling will test the valve's solenoid and electrical connections. We can often perform a repair to free a stuck valve, but if it's failed, we'll recommend a precise replacement to restore your system's full heating and cooling functionality.

Proactive maintenance is key to preventing issues like short cycling and valve failures. We recommend bi-annual tune-ups—once before the intense cooling season and once before the milder heating season. Our maintenance visit includes cleaning coils, checking refrigerant levels, calibrating thermostats, inspecting electrical components like the reversing valve solenoid, and ensuring proper airflow. This not only improves efficiency and comfort but also helps us catch small problems before they lead to a costly breakdown during a Tucson heatwave.
