ProAuto • June 28, 2025

At ProAuto in Morton Grove, IL, we understand the critical role your vehicle's air conditioning and heating systems play in ensuring comfort and safety throughout the year. Whether it’s blistering heat or freezing cold, a well-functioning A/C and heating system can make all the difference in your driving experience.

Most of us are aware of the discomfort of a malfunctioning car climate system just when we need it the most. That's why we believe it's essential to stay educated on how these systems work and how to maintain them. In this blog, we are excited to share our expertise, providing you with crucial insights into auto A/C and heating systems and how you can ensure they perform optimally.

Understanding Your Car's Climate Control System

To effectively care for your vehicle’s climate systems, it's important to understand their basic mechanics. The auto A/C system primarily involves components such as the compressor, condenser, evaporator, and various types of refrigerant. These components work together to remove heat from the cabin and provide cool air during hot weather.

In contrast, the car’s heating system attaches to the engine's cooling system, utilizing the heated coolant to warm the air before it enters the cabin. Both systems rely heavily on proper fluid levels, clean filters, and the integrity of their respective parts.

Common A/C and Heating Issues

At ProAuto, one of the frequent concerns we see are issues with A/C units failing to cool the vehicle adequately. Often, this can be traced back to a refrigerant leak or a failing compressor. Similarly, heating systems may experience issues such as blowing cold air due to problems like a failing thermostat or issues with the heating core.

These are typical issues that can arise as cars age or go without regular maintenance, emphasizing the need for periodic checks and servicing, especially as seasons change.

Proactive Maintenance Steps

Being proactive with your A/C and heating maintenance can save you from unexpected breakdowns. Here are some guidelines from our team at ProAuto in Morton Grove:

  • Regularly Inspect and Replace Air Filters: Clogged or dirty air filters can drastically reduce efficiency and air quality within your vehicle.
  • Check Refrigerant Levels: Low refrigerant is a common cause of A/C failure. Ensure your refrigerant is at optimal levels and check for leaks.
  • Take Note of Unusual Noises or Smells: Odd noises or smells might indicate a problem. Bringing your vehicle in for inspection at ProAuto at the first sign of trouble can prevent more significant issues later on.
  • Schedule Professional Checks: Regular professional inspections can help identify potential problems before they become costly repairs.

Signs You Need to Visit ProAuto

Sometimes minor issues can go unnoticed without expert inspection. Here are some signs that you should bring your car to ProAuto for a checkup:

  • Ineffective Heating or Cooling: If the climate system takes longer than usual to reach the desired temperature or doesn’t reach it at all.
  • Unusual Moisture: Puddles under your vehicle or fogging windows can be indicators of cooling system issues.
  • Strange Sounds: Hissing, rattling, or squealing noises should not be ignored.
