Arizona Auto Refrigeration specializes in keeping vehicles comfortable and dependable in the Arizona heat. From daily drivers to heavy-duty commercial units, our technicians use proven diagnostic methods and modern equipment to service, repair, and restore your vehicle’s air conditioning and heating systems.
A/C Service and Repair
Your A/C system works hard in Tucson. When it stops cooling, it’s usually due to low refrigerant, leaks, electrical issues, or failing components. We diagnose the problem accurately and repair it the right way.
Common services include:
• System diagnostics
• Leak detection and repair
• Compressor, condenser, and hose replacement
• Refrigerant recharge (R12, 134A, and 1234YF)
• Electrical and control system repair
Your heater and A/C share key components. When the heater begins to fail, you may notice weak airflow, fogging, or lack of defrost. We restore proper heat and cabin comfort.
We replace:
• Heater cores
• Heater control valves
• Blower motors
• Thermostats
• Related HVAC components
