Regular ac maintenance keeps your system running at peak efficiency, which can significantly lower energy bills and improve cooling performance. During a maintenance visit, our technician cleans or replaces filters, inspects coils and drainage, checks refrigerant levels, tightens connections, lubricates moving parts, and tests safety controls and thermostats. This proactive approach prevents minor issues from becoming major breakdowns, helps your system last longer, and ensures safe, consistent cooling throughout the hottest Arizona months.
Signs of a refrigerant leak include weak cooling, hissing sounds near the coils or lines, ice buildup on the evaporator coil, higher energy costs, or visible oily residue around refrigerant connections. If your unit frequently shuts off or your thermostat setting becomes less effective, a leak may be to blame. Our technician uses specialized tools to safely locate the leak, repair the damaged component, recover and recharge refrigerant to the correct level, and verify the system’s pressure and performance—restoring cooling capacity and preventing damage to your AC.
While some basic upkeep—like changing or cleaning filters—can be done by homeowners, a full air conditioner tune up requires professional tools and training. It involves checking electrical connections, cleaning coils, adjusting refrigerant charge, lubricating motors and bearings, testing safety switches, measuring airflow, and verifying control operations. Incorrect procedures can damage components or compromise safety. Booking a tune up with ZonAir ensures comprehensive, expert service that maximizes efficiency and reliability.
The thermostat is the control center of your entire cooling system. If it malfunctions or becomes inaccurate, it can cause uneven cooling, short‑cycling, increased energy use, or system strain. A modern thermostat improves comfort control, can optimize temperature schedules, and supports newer technologies. Our technicians diagnose issues ranging from wiring faults and sensor errors to failed components—then repair or replace the thermostat to restore proper temperature regulation and help your system run more effectively.
A proper air conditioner installation involves more than plugging in a new unit. We carefully calculate load requirements to match capacity to your home, choose compatible, energy‑efficient equipment, place components for optimal airflow, connect refrigerant lines, charge refrigerant accurately, seal ducts, and calibrate controls. Our meticulous process ensures your system runs safely, efficiently, and quietly. After installation, we test cooling output, inspect all connections, and clean up thoroughly—leaving you with a perfectly installed system and peace of mind.
