Why is my car air conditioner blowing hot air? With Spring finally here so are higher temperatures. When we want a little relief from the hot sun heating up the interior of our vehicle, we expect cool air to come out of the vents. Unfortunately over the winter months the air conditioning system can lose its charge or an electrical malfunction may occur. Sometimes seals or parts wear out, allowing the freon to leak or a pressure switch can malfunction, preventing the compressor from operating. Whatever the case may be, our highly experienced technicians can locate and repair your problem to get you back to comfortable driving in the summer heat.
