Car, Truck and SUV Air Conditioning Service

Servicing your car’s air conditioner can take one of two forms: 1. topping off the existing freon, or 2. removing the freon from the system, removing any impurities and returning it to your system with freon added to make up the required amount. Normally topping off is all that is required unless parts have been removed to perform repairs.

Car Air Conditioning and Comfort System Repair in Phoenix

We have the equipment required by the EPA for freon recovery should your air conditioner need repair. Our technicians are experienced and meet the requirements to use this equipment. If necessary we will repair leaks and replace any defective or malfunctioning components.

Heating/Heater Core

Heat for comfort heating is extracted from the coolant used to cool your vehicle. Hot water is circulated through the heater core which is similar to a car radiator but much smaller. Heating problems can often be due to a plugged heater core, but can also be due to low coolant or a defective cooling system thermostat.


The blower is located in the passenger compartment underneath the dashboard. It blows air through the evaporator if cooling is called upon, and through the heater core if heating is needed. If it fails we can replace it.

Car, SUV and Truck Climate Controls

The climate controls are located on the dashboard and allow you to decide whether you want heating or cooling. There is generally a dial to make more in depth changes such as the blowing power and how hot or cold the air should be. In most cars the controls consist of electrical circuits and mechanical linkages. Some cars however substitute pneumatic circuits for the electrical ones. In any case; we will find your problem, correct it, and have you driving in comfort once again!
