Auto Air Conditioning Repair in Rockwall, TX

How do my car’s air conditioning and heating systems work?

We take advantage of the fact that we can stay warm in our cars during Heath winters and cool during Royse City summers, but our vehicles’ air conditioning and heating systems are fairly complex. Your vehicle’s air conditioning system does not create cold air. Rather, it takes the heat and moisture out of the air in your car and leaves behind the cooler air. To heat up your car, hot engine coolant is circulated through a small radiator, which is often called a heater core. There is a fan in front of the heater core to blow cool air to blow cold outside air over the fins. As this air travels through the heater core, it heats up and this is the warm air that blows out of your heater vents.

Your vehicle’s air conditioning system includes the condenser, compressor, expansion valve, and evaporator. Refrigerant or coolant is compressed in the compressor and turns into a hot gas. This hot gas is cooled into a liquid state in the condenser, which is similar to a small radiator, then travels to the expansion valve. In the expansion valve, also called the orifice tube, the refrigerant turns back into a gas and rapidly cools in the evaporator, entering the low-pressure side of the air conditioning system. The receiver contains a desiccant bag to remove and collect unwanted moisture/water and impurities. A fan blows over the evaporator and cools the air that blows out of your vents. Now that the refrigerant is in a gaseous state, it can absorb heat from the air passing through the evaporator fins. The refrigerant then travels back to the compressor through the suction hose of the air conditioning system to get compressed back into a high-pressure gas and begin the process again.

If any parts of your vehicle’s heating or air conditioning systems are damaged, it can affect the entire system. If you sense a problem, feel free to bring your car or truck to Horizon Auto Center in Rockwall today.

What is an air conditioning evacuation/recharge?

If the interior of your BMW, Toyota, Ford, or Audi feels uncomfortable even with the air conditioning or heater on, your air conditioning system likely needs repairs. Any time a component of your air conditioning system is repaired or replaced, the system must be evacuated before it can be recharged. This is done because once the system is opened, moisture from the outside can get in and freeze, which could potentially cause more damage in the future. An air conditioning evacuation also makes sure that all the gases are removed before new refrigerant is added. 

 

At Horizon Auto Center in Rockwall County, our skilled technicians will hook up specialized equipment that monitors the high and low-pressure sides of the air conditioning system. We will use a special vacuum to remove any gas, air and moisture in the system, and will monitor this pressure as we work to ensure there are no leaks. If there are none, your air conditioning system is successfully recharged. Your air conditioning system should be recharged around every two years.

 

How do I know if my vehicle needs a heating & air conditioning service?

Whether you own a Ford, Chevrolet, BMW, or Mercedes-Benz, there are universal indicators that there is a problem with your car’s air conditioning and you will need to come in for an air conditioning evac/recharge service. Here are some signs to watch out for:

  • The air is not cooling.

Most of the time, your air conditioning loses its cooling properties because there is a low level of refrigerant, your condenser is broken, or the compressor has a broken or damaged belt.

  • You hear strange noises when your air conditioning is on.

Noise usually comes from a dying compressor, but some other common causes can be a cross-contaminated refrigerant or the use of the wrong lubricant.

  • It seems moist inside your vehicle. 

The common cause for moist air inside your car is usually moisture or debris trapped inside your air conditioning system.

  • The air from your air conditioning smells.

If you have not used your air conditioning in a while, bacteria and fungus can settle into the system, creating a foul smell.

  • Something is leaking from your air conditioning. 

Leaking refrigerant is dangerous and this issue should be addressed as soon as possible.

 

 

Here are some tips to keep your car cool in hot weather in Rockwall, Texas without the air conditioning: 

  • Use a sunshade or window visor.
  • Park in a shady area.
  • Purchase a solar-powered fan.
  • Keep windows slightly cracked.
  • Throw blankets over your seats.
  • Use a dash cover.
  • Keep your precious possessions away from the sun.
  • Cover your steering wheel with a towel.
  • Park in a garage when possible.
