Why Is Your AC Blowing Warm Air In Your Car?

With the bright summer season just around the nook, it is the best time to take your car out for a long drive. Nevertheless, nothing can ruin a summer’s delight like a damaged air conditioner in your car. Furthermore, the air conditioning system in your car is one of the most complicated pieces of equipment to figure out and always requires professional assistance for maintenance along with car repair in Plano, TX.

Reasons For Car AC Blowing Hot Air

Here are some reasons your car’s air conditioning device is blowing hot air.

Coolant Leak

A coolant leak is frequently the cause of a car AC blowing warm air. Refrigerant is a fluid that flows through the air conditioning system of your car, broadening and contracting as it eliminates heat and humidity from the cabin. None of the other air conditioner elements will work properly without appropriate refrigerant levels.
A leak can occur due to an old hose or a rusted or punctured evaporator. However, don’t expect to find a refrigerant leak quickly. A liquid puddle in or under your car is unlikely to be noticed. Unlike motor oil and other essential car liquids, antifreeze dissolves when exposed to air. Sometimes you’ll get lucky and recognize an oily residue right where the leak is.

Broken Condenser

The coolant consumes heat and humidity as your AC system draws them out of your cabin. The condenser’s task, in turn, is to maintain the refrigerant so that the cycle can persist. The process fails if the condenser fails to do its job. That’s when a shockwave of hot air hits you in the face.
The condenser is located in the front of the vehicle, between the crate and the heating element. It uses air flowing through the crate to help with cooling. If the condenser is obstructed or clogged by road hazards, air cannot reach it, and the refrigerant cannot cool properly.

Damaged Compressor

The compressor is the soul of your car’s air conditioning system. It is in charge of distributing the refrigerant throughout the system. If this component fails to function properly, the antifreeze will be unable to reach the compressor for cooling.
Compressor problems are more likely to occur after long periods of inactivity, such as during long winters when AC isn’t required. To avoid this, many modern models keep the condenser active all year by initiating it under the defrost setting.

Issues with the electrical circuit

If all AC elements are in perfect working order, your vehicle may be blowing hot air due to an electrical problem. A tattered wire or a ripped fuse can inhibit an otherwise healthy air conditioner from working. A full visual check of your car’s fuse box and wiring is the first step in diagnosing and fixing an electrical problem.
So if any of these issues are causing your vehicle to blow warm air, it is better to take it to a mechanic.
