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, but Dennis Johnson's Auto Repair in Madison can handle them all.
Your A/C system is complicated, to say the least. Compressors, high pressure lines, special gasses, condensers, actuators, electronic and vacuum signals, and multiple other aspects of your car’s air conditioning system all have to work together in harmony to effectively cool your vehicle. While air conditioning is something you can generally live without, it’s definitely nice to have, and typically a small fix can get your system back up and running. The longer an A/C system remains unoperational, the more problems it will develop, so it’s a good idea to have it serviced regularly.
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 inconvenient and 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.
