When to Service Your Car’s Air Conditioning

Posted on May 18, 2021

Why is My Car AC Not Working? 

Summer is fast approaching, and it won't be long before the heat has us running the air conditioner for long durations when driving. 

There's nothing more regretful than getting in your car on a hot sunny day to find out your air conditioner is blowing warm air or giving out a foul smell. These can indicate a bigger problem at play, and it's advisable to let a professional mechanic look at your car's air conditioning system.

The most suitable time to consider when to service your car's AC is before you require it. Even though it was working fine last year, parts could deteriorate over the cold winter months. 

A pre-summer checkup would be exceptionally crucial if you're planning a road trip! It can prevent costly AC repairs and give you the benefits of a more relaxed and comfortable drive with improved mileage.

Here are some of the reasons your air conditioner needs regular checkups and servicing.

Refrigerant leak

Leaking refrigerants is one of the most common reasons for your car's AC malfunction. Whenever there is a leak, the refrigerant level will decrease rapidly. Before you realize it, your air conditioner would blow warm air.  

Car air conditioning repair, which includes refilling the system with refrigerant, is a job best left to a professional mechanic. Even if you find the leak, recharging the system without professional help can be tricky and complicated. 

Compressor malfunction

Your car's air conditioner has many components, but your compressor is the heart of the system. It acts like a pump, taking the refrigerant, pressuring it, and then pushing it to the evaporator. There are several potential reasons for the compressor to stop working. A common reason for compressors to develop complications is long gaps without use. Other reasons could be low refrigerant level, an electrical malfunction in the compressor, or overheating.  

Fan issues

Most automobiles have an individual multi-speed fan that pushes air through a series of ducts and vents. A set of resistors or a small computer module control the multiple speeds of the fan. If both of these get too hot, they can burn out and eliminate certain fan speeds. As a result, the fan gets held at a single pace or stops altogether. Electrical issues may not be the only reason for the fan to stop running. Cracks may appear in the fan due to debris from the road. In such cases, replacement is the only way out. A professional mechanic can best handle car AC fan problems, especially electrical issues. 

Blocked or faulty condenser

The condenser of your vehicle's air conditioning unit re-cools hot refrigerant after compression. The airflow coming from the front of your car helps the condenser to cool. However, unwanted things such as debris from the road can block your condenser intake and circulate hot air through the compressor. Another reason for a failing condenser is the wear and tear of the seals and tubes. In cases like this, the entire unit will need replacement. 

Home mechanics or self-help experts should not replace AC condensers as the system has high-pressure properties, requiring special tools. In addition, some regulations forbid the release of refrigerant into the atmosphere, mandating the use of special recovery equipment. 

So, before the question "Why is my car's AC blowing hot?" frustrates you completely,  take your car to a professional garage for a check-up and repairs.
