A MORE COMFORTABLE DRIVING EXPERIENCE

Chances are some of you have driven an old clunker that had heating and air issues. Having no air conditioning is the lesser of two evils because you can simply roll the windows down to cool off. No heat, however, can be a major problem during the winter because you’re unable to defrost and heat your vehicle properly. For those of us accustomed to being in comfortable temperatures at all times, driving anywhere can be a miserable experience when the heat or air conditioning doesn’t work right. To better understand what could be causing your heat and air conditioning issues, let’s review how your auto’s HVAC unit works.

Engine coolant (also commonly known as antifreeze) circulates through the heater core. A fan blows cold air over the heater core which, in turn, heats the air before it travels through the vents and into the cabin of your vehicle. The process seems simple enough, so what could cause the heating to fail? Mainly, the issue arises from a corroded or clogged heater core. This leads to coolant leaks and, even, to the heat not working at all. If you notice a sweet chemical smell or the windows steaming up inside your vehicle, then you may have a coolant leak.

The air conditioning system is a little more complex than the heating system. Refrigerant, or Freon, is in a gas state at room temperature. When you turn the A/C on in your car, it flows through the compressor and becomes hot. Next, the hot gas goes through a cooling process in the condenser which converts it to a liquid. The heated, (now) liquid refrigerant once again becomes a low-pressure gas after its journey through the expansion valve, and the evaporator cools it. The evaporator is akin to the heater core in that a fan blows air over it, and the cool air flows through the vents into the cab of your car. Since this is a complex system, there could be several reasons your air conditioner doesn’t work properly. It may need to be recharged with more refrigerant, but if that doesn’t help in the long run then you may have a leak. The leak will need to be patched or parts may require replacing.

Heating & Air Conditioning Facts & Information

Your vehicle’s HVAC system is important not only for comfort, but for defrosting and defogging windows, uninterrupted flow of engine coolant, and proper operation of belts which drive your alternator, power steering, and water pump. Heating and cooling issues come in a variety of shapes and sizes depending on the type of car or truck you drive and the make or model of that vehicle, but Garcia Automotive Service in Greenville, TX can handle them all.

Your heat and A/C system are complicated, to say the least, requiring the right tools, and constant training to keep up-to-date on the new information and diagnostic tools required to take care of your specific system.  Our technicians at Garcia Automotive Service have experience in all makes and models and can quickly find and solve any issue you might have with your heat and A/C system should it be due to an issue with your compressors, high-pressure lines, special gasses, condensers, actuators, electronic and vacuum signals, or multiple other aspects of your car or truck.  Your air conditioning system has to work in harmony to effectively cool your vehicle infrastructure and when needed heat the inside of your vehicle for your comfort.  The longer an A/C system remains broken the more problems it will develop, so it’s a good idea to have it serviced regularly.

We have found that the heating systems are generally far more reliable than A/C since they primarily operate on circulating engine coolant.  However, if you’re having heating issues, the consequences are usually far greater if neglected.  Lack of defrosting and defogging ability is not just inconvenient but also extremely unsafe.  A clogged heater core can cause engine overheating, and a failed heater core will leak coolant into your vehicle, damaging other components. If your heater is misbehaving, have it inspected immediately.  Often a simple coolant flush will correct the issue if we can catch it quickly.
