COMFORT SYSTEMS

In some places, air conditioning is considered an optional feature. Not in Arizona! Make sure your comfort systems are in peak working order. Bring your car in to Hi-Tech for:

All System Diagnosis

At Hi-Tech Car Care we have the equipment and expertise to locate and repair any problems you might be having with your car's comfort systems. We will check the system for leaks and check for proper operation of the compressor, condenser, expansion valve, evaporator and receiver/dryer.

Air Conditioning Service

Servicing your automobile air conditioner can take one of two forms: 1. topping off the existing freon 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.

Air Conditioning Repair

We have the equipment required by EPA for freon recovery should your air conditioner need repair and our technicians are certified in its use. 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.

Blower

The blower is in the passenger compartment underneath the dash board. It blows air through the evaporator if cooling is called for and through the heater core if heating is needed. If it fails we will replace it.

Climate Controls

The climate controls are located on the dashboard and allow you to decide whether you want heating or cooling and how much you want. In most cars the controls consist of electrical circuits and mechanical linkages. Some cars substitute pneumatic circuits for the electrical ones. In any case; we will find your problem and correct
