Air Conditioning and Climate Control Systems Toronto & Etobicoke

A car’s air conditioning and climate control system makes it possible for drivers to enjoy comfortable weather during every season. Unfortunately, these systems can experience problems that prevent them from cooling or heating the car’s interior.

If you have one of the following problems with your car’s climate control, a professional mechanic will look for common causes.

#1: Air Conditioner’s Air Isn’t as Cool as it Once Was

This is a common problem that drivers often notice during the first warm days of spring or summer. When you find yourself cranking the A/C as high as it will go, you know that something bad has happened.

Numerous problems can cause this symptom. Some of the most common include:

  • Freon leaks
  • Vacuum leaks
  • Clogged tubes
  • Damaged blower motor
  • Failed condenser
  • Damaged evaporator
  • Failures with relays, fuses, or switches

Service professionals diagnose this problem by looking closely at the air conditioning system. They may use black light dyes that show where leaks occur.

It’s best to have your air conditioner serviced often. If you have a leak, then your A/C can’t work efficiently. That means it will struggle to keep up with your demands, which adds stress and increases the chance of complete failure.

The earlier you have the problem diagnosed, the less it costs to fix.

#2: Air Conditioner Has Weak Airflow

Weak airflow also forces your air conditioner to work harder than usual. Of course, it also affects performance. If the air seems to barely leak out of the vents, then you can’t cool the cabin as quickly as you once did.

Common reasons for this problem include:

  • Broken ventilation fan
  • Damaged seals
  • Loose hoses
  • Mold in the evaporator core

Mechanics often look for these problems by checking connections and inspecting the evaporator core. If the evaporator core has excess moisture in it, then there’s a good chance that mold or mildew exists.

#3: Heater Doesn’t Warm the Cabin

Heaters break for various reasons. As a driver, you just know you’re cold and the heater doesn’t work well. This problem could actually come from diverse causes that include:

  • Broken heater core
  • Low coolant levels
  • Damaged water pump
  • Broken thermostat
  • Damaged blower

Mechanics rule out problems by testing the heater under different conditions. For instance, they might drive the car for a few minutes to find out whether the system creates any heat at all. If it does, then they can rule out the heater core.

They’ll also check fuses, fluid levels, and individual parts to make sure they aren’t damaged. This helps them concentrate on plausible reasons that the heater doesn’t work.
