Problems with heating or air conditioning (A/C) can make any journey miserable. More importantly, poor ventilation puts your safety at risk. Windows can mist up and reduce visibility, while a stuffy cabin makes driver and passengers feel drowsy. If you’re experiencing anything like this, it’s time to have the car looked at.
Both the heater and the A/C rely on a fan that blows air into the passenger compartment. To provide warmth the air passes through a heat exchanger heated by hot coolant from the engine cooling system. (That’s why it takes time to get warm air on a cold morning.)
A/C is more complicated and actually works rather like a refrigerator. There’s a compressor that pumps fluid around the system. As the fluid passes into a heat exchanger it picks up heat from the incoming air. That warms the fluid but cools the air before it enters the cabin.
Typical problems with the heating and A/C systems include:
- No air coming in
- Strange smells
- Air not getting cold (when the a/c is on)
- Air not getting hot (when the heater should be on)
In most cases the fix is an easy one. It might mean replacing a cabin air filter or recharging the a/c with more refrigerant. In older vehicles it’s not uncommon for rust to build up in the heat exchangers, and that reduces efficiency. When that happens a thorough flushing is often all that’s needed.
NOTE: NEVER get a can of Quick Charge and try to solve your A/C problems yourself. These products contain solutions meant to stop up leaks, but they also stop critical air flow for the system drastically cutting the performance and longevity of your system. Once this happens, the only way to correct it is to replace the entire A/C system.
Our technicians here at FrankLynn Automotive are familiar with the heating and A/C systems on almost every make and model of car and there are few problems they haven’t seen before. Don’t put up with being too hot, too cold or having to open a window for fresh air. Let us take a look at it for you.
