Top Three Causes of Warm Air Blowing Out of Your Car’s Air Conditioner

Top Three Causes of Warm Air Blowing Out of Your Car's Air Conditioner

A lack of proper airflow can be unpleasant. Make time to visit our shop if your air conditioner needs to blow cold air or operate as it should.

While the summer heat in Massachusetts doesn’t last as long as we’d all want, it may make driving in the summer uncomfortable if your air conditioner isn’t operating at its best. Fans can malfunction, Freon can leak, and compressors can deteriorate. These are just a few items we check to ensure they are in excellent working order so you can stay cool all summer.

Three Indices of a Faulty Car Air Conditioner 

1. Leak of Refrigerant 

Because refrigerant rapidly turns into a gas when it isn’t under pressure, refrigerant leaks are unusual. Since air conditioning systems are sealed, topping the refrigerant is unnecessary. A leak needs to be fixed if the refrigerant level is low.

The traditional tell-tale puddles of fluid under your car, like those from an antifreeze or oil leak, don’t appear when your A/C system leaks. The oily residue that may be seen on or near the A/C hose units or connectors is one less dangerous symptom of a leak that our professional experts are trained to look for.

2. A decrepit compressor 

The compressor used by your car’s air conditioning system moves the refrigerant via a network of pipes and filters to remove heat from the cabin. Compressor failure can result from various factors because it is a complicated mechanism, including pollutants or other malfunctioning system components.

Here are some pointers for extending the life of the air conditioner in your car. First, regardless of the weather outside, run the air conditioner in your car for around 10 minutes monthly during the off-season. Since most current vehicles turn on the air conditioner when the defroster, which is utilized year-round, is turned on, it is simple to accomplish this.

A complex network of wires in your car’s air conditioning system, including fuses and relays, work together to ensure safe functioning.

The system automatically shuts down whenever one of these electrical components malfunctions due to ageing or a flaw.

3. Issues with the electrical system

These problems are only possible with the appropriate test tools and the diagnostician’s level of expertise.
