Air conditioning has become standard in vehicles. It’s not only important to stay comfortable and cool while driving on hot summer days, but it’s also crucial for defogging your windows during rainy weather. Plus, a well functioning A/C system filters out pollutants, keeping the air in your car fresh and clean.

How air conditioning systems work

A/C systems may seem simple from the outside, but creating cool air to keep your car pleasant and comfortable is a fairly complex process. When you turn on your air conditioning the compressor compresses the system’s refrigerant (Freon) and raises its temperature. As the Freon flows through the condenser and the dryer, it loses heat, moisture, and pressure. The refrigerant then flows to the evaporator, which gets cold as the temperature of the Freon drops even farther. The ventilation system then blows air over the cold evaporator, pushes cool air into the passenger compartment, and just like that, you receive the relief of cold air.

Signs of a broken A/C system

Your car’s A/C system is one of the vehicle components that often becomes worn and damaged due to frequent usage and aging. When your vehicle’s air conditioning fails to provide the right temperature that you need, it’s important to have it checked, serviced, and repaired. Some common signs of a broken or malfunctioning air conditioning system include weak airflow, the air losing its cool, an unusual or rattling noise, leaking refrigerant, or a bad or unusual odor coming through the vents when the A/C is on.

If you notice any of these symptoms, bring your car into HEART Certified Auto Care for A/C service in Evanston, Northbrook, or Wilmette.

A/C system recharge

Sometimes if your air conditioning begins to lose power and blow air that isn’t quite cold enough, it might just need a system recharge. An A/C system recharge simply means adding more refrigerant to allow the air to start blowing cold again. However, it’s important to note that needing an A/C recharge is indicative of a larger problem. Your car’s air conditioning is a closed system and should not be losing refrigerant, so if you need an A/C recharge, it means you have a leak that needs to be repaired.

The problem is, Freon is a colorless gas, so most of the time you can’t tell where it’s leaking out from. To get around this, when we do a recharge at HEART, we add a dye to the new Freon that we are introducing to the system. The dye stains the part that it leaks out from, allowing us to find the location of the leak and repair it.

Keeping your A/C working at its best is important to your comfort in the summer. Routine inspections can keep your unit from developing bigger problems, so it’s a good idea to ask for A/C service when you have your oil changed and your tires rotated.

If you’re experiencing problems with your car’s air conditioning, bring your vehicle by one of HEART’s three Chicago area locations in Evanston, Northbrook, or Wilmette for A/C service. We’ll have your car feeling cool again in no time!
