What auto a/c and heating system does:

Auto heating and A/C systems function to keep your car cabin warm in the winter and cool in the summer. The auto A/C system additionally offers a double function of working your defrost in the winter. Heating systems are comprised of a heater core which acts like a little radiator behind the dash, fan, and hoses which draw the heat from the engine to the core. Auto A/C systems operate similarly, by delivering coolant to the fan to blow cold air in the cabin.

Why Auto A/C & Heating System Repair service is important:

Heating and A/C systems can wear out over time with use. Hoses can easily stop-up and leak if not serviced, leading to poor efficiency or a lack of cooling and heating completely. Correct routine maintenance can keep your automobile comfortable for you and your passengers.

The best ways to tell if your heating and A/C are having problems:

  • If your A/C blows just a little cooler than the air outside
  • Air that blows in smells moist, musty, or like mildew
  • Your cabin does not heat up in cold weather, or is just somewhat warmer than outdoors
  • The defroster takes longer than normal to function, blows in filthy air, or doesn't operate
  • Your heater or A/C only operates when driving, not when idling, or stops blowing when the vehicle is still
  • Your heating unit blows chilly air, or the air conditioning blows warm
  • At the highest setting, your vents do not put out much air

An in-depth inspection of heating and a/c systems includes:

  • Checking the interior and blower
  • Checking radiator coolant level, hoses, pressure cap and thermostat
  • Screening the compressor belt
  • Examining for cracks or additional damages
  • A cooling system pressure examination
  • Contrasting the air conditioning pressure to producer specifications
  • Examining the air conditioning system for refrigerant leaks
  • Check the interior vent air temperature

Heating System RepairDid you know?

Your car's engine is the power source for both heating and air conditioning systems. The systems also share other components, as the following diagram shows.

Here's what happens when you flip on the heat or the air conditioner:

Heating System

Heat is a byproduct of the engine's combustion process. The heat is absorbed by the coolant in your car's radiator. The coolant is then circulated through the heater core before returning to the radiator. The heating system also includes a series of air ducts, a blower motor and fan, and temperature and duct controls, which selct the desired temperature and direct the flow of warm air.

Air Conditioning System

This system shares air ducts, controls and a blower with the heater, but has its own refrigerant system. The air conditioning system is comprised of the following components:


This is a pump that pressurizes and circulates the refrigerant through the system.


As the refrigerant flows through the condensor, it gives up heat and converts from gas to liquid.

Receiver/Dryer or Accumulator

This is where clean, dry refrigerant is stored as it circulates through the system.

Orifice Tube or Expansion Valve

This is a metering device that controls the flow of refrigerant through the system.

Evaporator Core

Refrigerant enters the evaporator core as a liquid. Heat from the air converts the liquid refrigerant back into a gas, which cools the air before it enters you car.
