If you are looking for vehicle specific instructions, an online repair manual is the ticket. I recommend Alldata or Mitchell1, but also have a cool way to get a free repair manual, you need to check out today. Nothing stinks more than having your Air Conditioning go out while on a long summer trip. Of course I could tell you to get the system checked BEFORE you ventured out, but what good would that do now? There is not much you can do while driving to help when your A/C system has pooped out on you. There are a few things you could check though... make sure the condenser is free from obstructions (usually sits right in front of the radiator.) Check belt tension for the compressor, and make sure the clutch wiring is connected properly. Fan only blows two speeds, OFF and Full Bore?

Most likely your resistor is shot. The fan circuit has a resistor which controls the speed of the fan blowing air through your vents. When they go bad, you only have one speed, full blast. Usually an affordable fix, the hardest part is finding the location of the resistor under the dash. The HVAC system is complex to say the least. You need a repair manual to guide you to the specifics of maintaining and repairing your HVAC system. Checkout Mitchell1 for the best online repair manuals.

They come to your house or place of work and get you fixed up without the hassle of taking the day off or being without your car. Without the heating and air conditioning systems in today’s modern vehicles, we would all be miserable driving to our destinations. We take for granted the heat that keeps us warm in the winter months, and the cool air that refreshes in the summer time.

Let’s take a look at how both systems work to keep us comfortable all year round. The heater in your car is basically a smaller version of your cooling systems 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 which blows out your heater vents. Like your engines 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. 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. how much does it cost to install a central ac unitThis is due to the rapid expansion of the compressed gas. room ac unit portableThe same thing happens in your car’s air conditioning system. types of hvac unitsRefrigerant (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 your vents. Click Here For An Excellent Illustration and Further Explanation.

From time to time the A/C system needs to be recharged to bring it back up to maximum efficiency. Sometimes a leak may cause loss of refrigerant and will need to be fixed before refilling. It's difficult to tell if a leak is present without specific test equipment so let it up to a professional. In recent years, the EPA has phased out the use of R-12 Freon in all refrigeration systems and R-134 has become the new standard. If you have an older system with R-12 you may need to retrofit your system to handle the new R-134 refrigerant. Sometimes seals, hoses and even the compressor need to be changed. The problem arises when the older seals and hoses are not compatible with the new oils found in the R-134. Corrosion will cause the heater core (secondary radiator) to leak. This will manifest itself by leaving steam into the passenger compartment and fogging your windows. You will know there is a leak by the sweet smell coming from your vents. Unfortunately changing the heater core is usually not the easier job in the world as engineers tend to squeeze them into some pretty tight spaces under the dash.

Today automotive air conditioning is standard equipment on cars and trucks. Just 30 years ago this would've been considered a luxury option. Since this is one of the more troublesome systems, often leading to very high repair bills, it seemed only right to coverOn this page we'll start with the basic theory ofAt the bottom are links to advanced articles on individual components. You can find out what's wrong with your car today by examining these common problem areas. Remember that It's a lot easier to diagnose and repair AC systems with the basic knowledge of how they work. Therefore, reading and learning about them isn't a waste of time. Especially when you consider this area of the retail car repair business can be at times shady. When educated consumers start asking questions, estimates have a tendency to go down and automobiles fixed right on the first visit go up. All ac systems are designed to pump heat from one point toCommonly we remove heat from the inside and take it outside.

The basic theory states, heat will flow from the warmer object to the colder one. The greater the temperature difference between the two, the more heat flows. The substance used to remove the heat from the inside of an automobile is called refrigerant. On older automotive air conditioning systems the factory installed refrigerant was R12. An amendment to the United States Clean Air Act has mandated that we phase out R12 as the Since air conditioning systems with R12 are susceptible to leaks, ozone damage and environmental concerns pushed for the replacement ofThis was finally adopted into United States law as aIt started a new wave of AC specialty shops that performed conversions. Car-makers began using R134-A as the freon ofIn 2014 GM started using HFO-1234yf, believed to cause less damage to the ozone when released into the atmosphere. Mercedes-Benz will start using a CO2 refrigerant called R744 in 2017 models. Auto AC service will be more complicated going forward as HFO and CO2 types aren't compatible with the widely used R-freons.

Although the most common R 134 A air-conditioning systems operate in the same way with the same basic components as the R12 and HFO units keep in mind none of theThe HFO-1234yf goes a step further and runs at different pressures. All three use different lubrication oil for the compressor. Shops will have to get ready to service 4 different kinds of Freon. And consumers will have to pay more for repairs as compliance becomes more difficult. If you are unsure of what type of Freon is in your vehicle, there are under hood labels identifying which type is installed. Also the R12 service fittings are threaded connections and much smaller than their 134 counterparts that utilize a quick disconnectI have an article about converting old R12 to the new style freon below. Reading it can help avoid common problems. To understand how car ac refrigerant is used to cool the interior of the vehicle the effects of pressure and temperature should beIf the pressure is high so is its temperature.

pressure of the refrigerant is low then again so is its temperature. High PSI lines are small diameter and hot. Low side lines are larger and cold to the touch. Therefore, changing its pressure from a high pressure to a low pressure can easily change the temperature of the refrigerant. Temperature and pressure of the refrigerant is kept low inside theIt's circulated through a highly efficient heat ex-changer. This component is known asThe component is pictured above on the right. It works in reverse of the engine coolant radiator.  passenger compartment is transferred to this device and passed The heated refrigerant is then pumped forward to the air conditioning condenser, which is yet another heat exchange component. It's located in the front of the engine compartment. A condenser fan is used to blow fresh air across the coils and aluminum fins to remove the absorbed and stored heat within the refrigerant. The evaporator on the inside of the vehicle and the condenser on

the outside of the vehicle are solely responsible for the heat transfer properties of the entire system. These two components are supported and operated by the other parts of the automotive air conditioning system. More in-depth description of these components will be available in the Learning about A/C is important, because it can cost a lot or a little to repair.
