Stay comfortable year-round with professional air conditioning and heating repair services from Marshall’s Service Center.

Arizona temperatures place heavy demands on your vehicle’s climate control system, making proper maintenance and repairs essential.

Whether your AC is blowing warm air or your heater is not functioning properly, our technicians can diagnose and repair the issue.

Our AC & Heating Services Include:

  • Hook up gauges
  • Check system pressure
  • Check for power supply through system
  • Check and adjust belt tension
  • Add refrigerant as needed
  • Check temperature from vents

We inspect compressors, condensers, blower motors, electrical components, refrigerant levels, and heating system operation to identify the source of the problem.

Reliable Climate Control Repairs

Driving in Arizona without properly functioning air conditioning can quickly become uncomfortable and unsafe. We work to restore reliable climate control performance so you can drive comfortably in all seasons.

Air Conditioning in Arizona Is Not Optional

A vehicle air conditioning system in the Valley runs at high load for months at a time, which puts real strain on the compressor, condenser and seals. Most systems lose a small amount of refrigerant gradually through seals and hose connections, so performance tends to fall off slowly enough that drivers do not notice until a hot week arrives and the air is no longer cold.

Have It Checked Before Summer, Not During

The best time to have air conditioning inspected is in spring, before the first stretch of extreme heat. We check system pressures, inspect the compressor, condenser, blower motor and electrical components, verify belt condition and measure the actual temperature at the vents. A restricted cabin air filter is also a common and inexpensive cause of weak airflow. Our staff includes ASE Master Certified Technicians certified in heating and air conditioning.
