Things you must know about your Car A/C

Are you looking for a car a/c repair in Dubai? Here are some things that you must know about your car AC. 

The system starts with a compressor driven by the vehicle's engine. The compressor takes in refrigerant gas, compresses it into hot gas, and sends it to an air conditioning condenser. The hot refrigerant gas releases its heat in the condenser and condenses into a liquid. The cooled liquid then travels to an expansion valve, which drops in pressure. This allows the refrigerant to evaporate and cool even further, absorbing heat from the air in your car and turning it into a cold gas. From there, it travels back to the compressor to start over again. Have your car A/C regularly serviced to keep it running efficiently. Get in touch with Service for car a/c service in Dubai.

Have you faced a sudden Car AC breakdown? Here are the things you must know about your car A/C.

Let's start with a simple point: Air conditioning doesn't cool the air. Confused? Let's break it down. If you need to lower the temperature in your car, you flip on the a/c and enjoy the refreshing coolness. But how does it work? The A/C system pulls heat from inside your cabin, not by sending cooler air in but by removing heat from inside.

A/C uses a compressor to pump refrigerant through a series of tubes and coils that suck out that pesky heat, lowering the temperature before sending it back into your car. While this is happening, an air handler sends air across another set of coils to cool it down even further before pushing it into your cabin. 

As we mentioned above, A/C isn't exactly like heating your car either—it's just a matter of reversing the process. Instead of taking the heat out of the cabin and sending it outside, heating systems remove heat from the coolant (or refrigerant) after it's been warmed up in an engine-cooling radiator and then send that warm air back into your car. 

"Freon" is not a type of refrigerant but a brand name.

Just as Kleenex is one brand of tissue and Rollerblades is a brand of inline skates, Freon is a brand name belonging to DuPont. It's not the only refrigerant on the market, and other brands provide similar products. This is important for you to know because some mechanics and technicians may try to convince you that you need "Freon" in your car, but other brands work just fine.

Freon itself serves as an umbrella term for various types of refrigerants from DuPont: R-12 (also known as CFC-12), R-22 (HCFC-22), R-134a (HFC-134a), and so on. However, these refrigerants might not be available in all countries due to different laws and regulations.

You should use recycled refrigerant only if you know where it came from.

You should only use recycled refrigerant if you know where it came from. The refrigerant source should be someone you trust, like an auto repair shop or an oil supplier. Car A/C Repair in Dubai is important, but there are things you must know about it before you can work with your mechanic. Make some calls and ask around, but make sure that you ask about the source of the recycled refrigerant. Recycled refrigerant can be contaminated with moisture, which can cause compressor damage. You should be able to see a clear liquid with no bubbles before using it in your car's A/C system.

You do not need an EPA license to buy refrigerants or products that contain refrigerants.

The EPA regulates the chemical refrigerant under Section 608 of the Clean Air Act (EPA). Under this regulation, the release of refrigerant into the atmosphere is prohibited unless it is done through an approved method. The EPA provides information on what equipment is needed to recover and recycle air conditioning refrigerants legally.

The EPA does not regulate the purchase and use of refrigerants by end-users such as car owners. Therefore, there is no need for you to have an EPA license to buy or use refrigerants in your automobile's air conditioning system.

R-134a does not affect your Ozone layer.

R-134a does not affect your Ozone layer and is non-flammable.

In 1987, the Montreal Protocol was signed by more than 100 nations to phase out the use of CFCs (chlorofluorocarbons) by 2000. Gases used to replace CFCs are called hydrofluorocarbons (HFCs), which do not cause ozone depletion but have a much higher global warming potential. HFC gases such as R-134a are not flammable and safe for use in a vehicle's passenger compartment. One advantage of R-134a over R-12 is that it is not flammable or toxic. Because there is no danger of fire or explosion when using R-134a, you can safely recharge your A/C system with this refrigerant without evacuating the refrigerant first. 

Don't worry about oil coming out with the refrigerant because that is normal.

While replacing the refrigerant, do not worry about seeing oil coming out of your A/C system. Since it is used to lubricate the compressor (the heart of the A/C system), there will always be some oil in the system. So, while it is normal for some oil to come out with the refrigerant if you notice too much of it, you have a problem!


Car A/C is one of those things that many of us take for granted. We leave it on while we're in the car or after buying a new car. Few people think about it much until something goes wrong. When you need Car A/C Repair in Dubai , There are many services available if you aren't familiar with properly maintaining your Car A/C.
