Why Is My Car’s Air Conditioner Blowing Hot Air?

It’s unusually hot outside so you turn on your car’s air conditioner. The air is warm, but this is normal at first; it will turn cold in a few seconds. The problem is that it doesn’t; you’ve got nothing but hot air blowing through the vents. What could be wrong? Extra Mile Tire Pros is going to list five reasons for the hot air below. Any one of these things could be the problem, and we can fix all of them.

1. Damaged Condenser

The first problem could be a damaged condenser. The condenser takes the hot refrigerant that has circulated through the air conditioning system and cools it down using outside air and a fan. To make the most of the outside air, the condenser is located directly behind the grille. Unfortunately, this opens it up to damage and clogs from road debris, which renders it unable to cool the hot refrigerant.

2. Malfunctioning Fan

Perhaps the condenser isn’t damaged or clogged but the condenser’s fan isn’t working. This, too, will leave you with hot instead of cold refrigerant circulating through the air conditioning system, and, as a consequence, hot air blowing through the vents. Unfortunately, you will continue to have hot air blowing through the vents even though the AC is on until you get the malfunctioning fan fixed.

3. Electrical Problem

The condenser fan might be malfunctioning because of an air conditioning system electrical problem. Your car, truck, or utility vehicle’s air conditioning system has a comprehensive electrical system all to itself, and many things can go wrong. There may be a problem with the wiring to the fan or another electrical system failure such as a non-responsive AC button on your vehicle’s dashboard.

4. Faulty Compressor

Another reason why your car’s air conditioner will blow hot air is a faulty compressor. The compressor circulates the liquid refrigerant through the air conditioning system after it compresses it from gas to liquid. The compressor can go bad if it isn’t used at least once a month. Consequently, your compressor might be malfunctioning if it’s been several months since you used your automobile’s AC.

5. Low Refrigerant Levels

Finally, low refrigerant levels will blow hot air through the vents because there isn’t enough refrigerant to cool the air. The refrigerant can evaporate over time and also leak through the hose connectors. We recommend that you schedule an AC service with us each spring so we can check the refrigerant levels and replenish them if necessary. We will also inspect the rest of the system for trouble.
