HEATING AND AIR CONDITIONING – WHAT YOU NEED TO KNOW

Driving a Mercedes Benz is dream, but if your air conditioning malfunctions on a hot summer day in Florida, it can become a nightmare. Superior handling and luxury components are two of the primary factors that entice drivers to choose a car from the Mercedes line-up, but finding the right place to meet your Mercedes service and repair needs should be at the top of your priority list, within the first few months of ownership.

Heating and Air Conditioning

BenzShops.com states that:
… Many owners of C-Class models have complained of problems with the air conditioning units in their vehicles, reporting A/C system failure after about 70,000 miles. The complaints state that only hot air blows, even when the temperature has been switched to the lowest possible setting. This could be a result of a complete failure of the system, in which case it would need to be replaced. If you suspect that there is Freon leaking from the unit, then you should take the car in to your trusted Mercedes service shop to have some tests run. It is possible that being low on coolant could also be responsible, as this can cause leakage. Additionally, there could also be other electrical failures. Addressing these issues early will put your mind at ease, before the weather gets too warm and riding in the car becomes unbearable.

Florida cars aren’t often in need of their heating units, but there are enough cold days to warrant a fully functional heating and air conditioning system. Here is a basic outline of the HVAC components and how they heat and cool our cars. According to autoeduction.com:

HEAT

The heater in your car is basically a smaller version of your cooling system’s radiator. Hot engine coolant is circulated through a small radiator, often times called a heater core. A fan is positioned in front of the heater core to blow cold outside air over the fins. As this air travels over the heater core, it heats up and becomes the hot air that blows out of your heater vents.

Like your engine’s cooling system radiator, the heater core can suffer some of the same issues. If the heater core becomes clogged with rust or sludge, you will no longer have heat. Also leaks can cause a cabin full of white steam and really mess up your windows. If you smell the sweet aroma of coolant when your heater is on, chances are, you have a small leak in the heater core. Often times the heater core is buried under the dashboard, and replacing it, is a major job.

A/C

The air conditioning system in your car is comprised of a compressor, condenser, expansion valve and evaporator. If you have ever used a can of compressed air to clean computer components, you will know that the bottle gets very cold in a short amount of time. This is due to the rapid expansion of the compressed gas. The same thing happens in your car’s air conditioning system. Refrigerant (AKA Freon) is compressed in the compressor and turns into a hot gas. In the condenser, this hot gas is cooled to a liquid state and travels to the expansion valve. As the Freon goes through the expansion valve it returns to a low-pressure gas and rapidly cools in the evaporator. A fan blows over the evaporator and cools the air that eventually blows out of your vents.
