How To Repair Heater Air Flow Restricted On 98 Honda Crv

The air conditioning organisation in your car is designed to cool down the air in the cabin of your vehicle to continue you comfortable on a hot day. It's something that we often accept for granted until information technology's a hot day and your car'southward A/C is not working. When you only get hot air instead of common cold air, it can be frustrating and extremely uncomfortable. If your air conditioner blows warm air, information technology is important that you get it looked at as soon as possible so you tin continue driving in cool comfort. In this article, nosotros're going to look at how your Car'due south A/C creates the cold air so y'all can more accurately diagnose what's going wrong.

How Does a Auto's A/C Work?

Your motorcar's A/C organization is one that operates a footling differently than y'all might retrieve. Instead of actually creating cool air, it instead removes the rut and moisture from the air inside of your car, leaving yous with cooler feeling air. In technical terms, the cool air is created by bravado air from either outside your machine, or from the cabin over cold coils. This cools down the air earlier it gets diddled out of the ventilation system into your motorcar to proceed y'all comfortable. Most systems are designed to blow very common cold air, between 32 and xl degrees! These cooling coils, called the evaporator, is where the actual cooling of the air happens. These coils are cooled by cold refrigerant flowing through them.

Most cars today use a refrigerant called R-134a which is a special refrigerant designed to work at the temperatures and pressure standard in a auto'due south A/C system.  As the cold refrigerant passes through the evaporator it absorbs the heat in the air which warms upward the refrigerant.  This warmer refrigerant now needs to be cooled back down so your A/C system can continue to operate.  This is accomplished by first compressing the refrigerant to a high pressure which also heats it up to a high temperature.

This hot refrigerant is so cooled downwardly by running it through the condenser.  The condenser is cooled by ambient air in the front end of your car just like the coolant in the radiator is cooled.  On most cars the condenser is actually in forepart of the radiator and gets cooled first to brand certain your A/C organisation gives yous consistently cool air.  This high pressure, at present cooled, refrigerant is so allowed to expand quickly every bit information technology passes through an orifice or expansion valve.  The expansion valve is a simple device that takes advantage of the fact that quickly expanding liquids and gases get common cold.  The procedure of liquids and gases getting cold during expansion is a scientific phenomenon you can prove by using an entire can of spray paint in one sitting and seeing how cold the can gets.

At present the cold, low-pressure refrigerant can return to the evaporator to absurd it and along with information technology, more air keeping your machine comfortable.  There are a few other components in the system like temperature and pressure sensors, hoses and the dryer or accumulator.  The dryer is where any moisture is removed from the refrigerant, the refrigerant is filtered to make certain information technology all enters the compressor as a gas, and the oil for the organisation is equally distributed through the refrigerant passing through.

Common A/C Issues & How to Prepare Them

If your car's air conditioner isn't working properly and is blowing hot air and so one of these systems isn't doing its task properly. Getting to the root of the problem can have some fourth dimension and endeavor, only nosotros have simplified the process past providing yous with the most common A/C problems along with how to resolve these problems once they're discovered.

The Evaporator or Condenser is Chock-full

Since there are ii components that require air to be moving through them, the evaporator and the condenser, information technology is possible one or both of these are clogged and non getting the proper air period.  Bank check the forepart of your vehicle for debris, the engine cooling fans for proper operation, and your cabin air filter for droppings and dirt.  The refrigerant in your arrangement likewise needs to be able to flow properly through the system.  Check your compressor for proper performance, clogs in your organization and the proper amount of refrigerant.  All of these tin be checked by observing the pressures around the system both before and after the compressor and all the other components.  This can be washed with set of A/C gauges to mensurate both the high and low pressure sides of your A/C system.

If you detect unusually loftier pressure before any particular components and unexpectedly low pressures after them, there is a good chance there is a clog in that component.  If this is the case, you will nigh likely find the clog in the accumulator or the condenser.  If y'all don't have a large enough pressure increase across your compressor you may exist in need of a new Air conditioning compressor.  If yous have lower than expected pressures on the low pressure side of your system, may but accept a low refrigerant level.

Electrical Arrangement Issues

Let's proceed information technology uncomplicated since your A/C arrangement is very complex. There are so many dissimilar wires, fuses, pressure switches, and more that all work together to start blowing cold air into your machine. Therefore, if just one of these components end performance, it is very likely that your entire system volition shut downward. For a novice, the place to start here is by doing a visual inspection of the wiring to see if in that location are any that are damaged or frayed. Repair or replace any damaged wires if you tin notice them, if non, you may have to take the motorcar to your dealer or a mechanic who will have the expertise to diagnose the specific issue.

The A/C System Needs Recharging

If you exercise not take enough refrigerant in your car's A/C organization the compressor may not exist able to raise the organisation pressure loftier enough for the expansion valve to exist effective in cooling downwardly the refrigerant.  Due to the high pressures of your air conditioning system and the volatile nature of the R-134a refrigerant used, information technology is not uncommon for some of the refrigerant to leak out over time causing a depression pressure level condition in your arrangement.  If y'all observe this to be the reason why your car air conditioner is blowing hot air add Red Angel A/C Terminate Leak to your vehicle'southward air conditioning system to seal whatever leaks no matter how small they are before you recharge the arrangement.

Crimson Angel A/C End Leak 1 Shot comes in an easy to use aerosol tin can that can exist installed quickly and easily without any tools and also contains 2.five ounces of R-134a to help bring your system support to normal operating pressure.
