AUTO HEATING AND
AIR CONDITIONING SERVICE AND REPAIR

In Texas, a reliable car air conditioning and heating system is more than just a luxury—it’s a necessity. Your vehicle’s HVAC system (Heating, Ventilation, and Air Conditioning) controls the climate inside your car, ensuring every ride is comfortable, whether it’s a blazing summer day or a chilly winter morning.

 

How Your Car’s HVAC System Works

Your car’s climate control system is a complex network of components working independently yet harmoniously. A failure in your air conditioner doesn’t necessarily mean your heater will stop working, and vice versa.

Key components include:

• Compressor: Engine-driven pump that compresses and circulates refrigerant gas

• Condenser: Cools the refrigerant, located at the front of your vehicle

• Evaporator: Absorbs heat from inside the cabin, cooling the air

• Expansion Valve: Regulates refrigerant flow between evaporator and condenser

• Refrigerant: The cooling agent that cycles between liquid and gas to cool your car

• Receiver/Dryer (Accumulator): Removes moisture and contaminants from refrigerant

• Cabin Air Filter: Filters out dust, pollen, and pollutants to keep your air clean

• Thermostat: Maintains optimal engine and cabin temperature

• Blower: Pushes heated or cooled air into the cabin

• Actuator: Controls airflow direction inside your vehicle

 

Types of HVAC Systems

Most modern vehicles use either the orifice tube system or the expansion valve system—some use a combination of both—for efficient climate control.

• The heater core acts as a heat exchanger, warming the air by channeling hot coolant from the engine.

• The refrigeration system absorbs and expels heat to cool your car’s interior.

• The ventilation system balances fresh air intake with temperature control for personalized comfort.

 

Why Proper HVAC Maintenance Matters

Your car’s HVAC system does more than regulate temperature—it’s crucial for safety and visibility. By dehumidifying the air, it prevents windshield fogging, keeping your view clear on humid San Antonio mornings and rainy days.

Regular inspections and maintenance of components like the refrigerant levels, filters, and electrical actuators help prevent breakdowns and costly repairs.

 

Signs You Need Auto Air Conditioning or Heater Repair
