Complete Climate Control Repair – Stay Comfortable in Every Season

The Misery of a Broken Climate Control System

Driving in the brutal, humid summer heat without air conditioning is not just uncomfortable—it’s exhausting and distracting. Conversely, shivering through the freezing winter without a functioning heater makes your morning commute miserable and leaves your windshield dangerously fogged up. If your vehicle’s climate control system is blowing warm, stale air in July or freezing cold air in January, it’s time to bring it to the climate control experts at Arnavalley Exon.

Comprehensive Auto Air Conditioning (A/C) Repair

Car A/C systems do not consume refrigerant (freon) like gas. If your A/C is blowing warm, it means the refrigerant has leaked out, or a mechanical component has failed. Our comprehensive A/C services include:

A/C Performance & Pressure Checks: We use specialized thermometers to test the exact temperature of the air coming from your vents, and connect manifold gauges to test the pressure of the system.
Advanced UV Leak Detection: We inject specialized UV dyes into the system and use electronic “sniffers” and UV flashlights to locate hidden leaks in rubber hoses or the condenser.
Precision Refrigerant Recharges: We safely evacuate the old, contaminated refrigerant, vacuum the system to remove moisture, and recharge it with the exact weight of pure refrigerant specified by the manufacturer.
Compressor & Condenser Replacement: We expertly replace seized A/C compressors, worn out magnetic clutches, and damaged condensers.

Complete Auto Heating System Repair

Your car’s heater relies on the engine’s boiling hot coolant to warm the cabin via a small radiator called a “heater core.” If your heater is failing, it could actually be a warning sign of a much larger engine cooling issue. We diagnose and repair:

Clogged Heater Cores: We aggressively flush the system to restore hot air flow.
Stuck Thermostats: We replace faulty thermostats that are stuck open, which prevents the engine (and the heater) from ever reaching operating temperature.
Blower Motors & Blend Door Actuators: If the air is hot but the fan won’t blow, or won’t switch to the defrost vents, we fix the electronic actuators and blower motors.
