How does Car Air Conditioning Work?.

There are 5 Main Components.




Expansion valve.


With over 30 years experience You can trust Snowmobile to diagnose, repair and re-gas your air-conditioning system.

Q: How frequently should my A/C be inspected?

A: How is the air feeling? Are you refreshed/full air flow? If you answered Yes, A/C inspection is Not necessary.

Q: What is re gassing the AC?

A: Fresh refrigerant is added to the system.

Q: Is it required, like an oil change?

A: If the refrigerant is a bit low, it can be topped off, the same as if you were a bit low on oil in the engine.

Q: Does my car air conditioning need to be re gassed?

A: If the system lacks efficiency then adding new fluid is called re gassing.

Q. What is the Car Air Conditioning Compressor?

A. The compressor is the heart of every A/C system. Want to stay cool, a functional, working compressor is essential. The compressor: Pressurizes the refrigerant that cools your air. Compressor - pumps refrigerant vapour under high pressure to the condenser. Your A/C system also consists of hoses and refrigerant charging ports.

Q. What is a Car Air Conditioning Condenser?

A. The condenser is located at the front of most vehicles. Air flows through the condenser, converting hot refrigerant gas into cooler, condensed, refrigerant liquid. Condenser - the condenser changes the high-pressure refrigerant vapour to a liquid.

Q. What is a Car Air Conditioning receiver/dryer?

A. Receiver-dryer, removes any moisture from the system. Found on vehicles with a thermal expansion valve. It is a safeguard, for preventing any harmful debris, moisture and liquids. (Compressors can't handle liquids, just Gas.) Preventsthese & other contaminants, fouling the compressor and other Air Cconditioning parts.

Q. What is a Car Air Conditioning accumulator?.

A. An accumulator is similar to a receiver-dryer. Regulates the quantity of refrigerant that goes into the evaporator. Stores any excess so, it cannot stress the operation of or damage the compressor.

Q. What is a Car Air Conditioning thermal expansion valve?

A. This thermal expansion valve is located between condenser and evaporator. A thermal expansion valve(often abbreviated as TEV, TXV, or TX valve) is a component in refrigeration and air conditioning systems that control the amount of refrigerant flow into the evaporator thereby controlling the superheat at the outlet of the evaporator.

Q. What is Car Air Conditioning evaporator?

A. Also sometimes referred to as the evaporator core, is one of the two (maybe three) heat exchangers in a Car Air Conditioning system. In a typical motor vehicle, the evaporator is usually located inside the passenger compartment, quite often behind the dash.

Q. What is Car Air Conditioning refrigerant?

A. Refrigerant is a specially formulated mixture, the sole purpose, for transforming hot air into cold air. It does this by absorbing and releasing heat, ultimately leaving cool air behind. The auto industry has since switched to the CFC free R-134a.
