Customers often ask me what is the new air con gas R1234yf & why was it necessary.
Hopefully this will help.
It started to be used by some vehicle manufacturers in 2013 and as of 01st January 2017 it was made compulsory that all new cars and light commercials vehicles had to have it as standard. The gas is very expensive and the old equipment cannot be used with this gas. A new machine is required and a more expensive type of oil.
All refrigerant gases have a GWP (Global warming potential) the lower the GWP the better for the environment.
In 2001 R12 was banned from being used it had a GWP of 10,680
This was replaced with R134A which has a GWP of 1,430
The new gas HFO-R1234yf Has a GWP of just 4
The new gas HFO-R1234yf cannot be used in vehicles designed for the old gas R134A
The old gas R134A cannot be used in vehicles designed for the new gas HFO-R1234yf.

Most vehicles have a recirculation button as part of their AC controls, but many of us aren’t sure when to use it. The simple rule of thumb is to use it in the summer and turn it off in the winter.

The recirculation button works by taking the air inside your car and recirculating it within the cabin, rather than pulling in fresh air from outside. On extremely hot days, if you don't use the recirculation feature, your AC system has to cool the hot air from outside, which can be less efficient. By recirculating the cooler air inside the car, you can cool your vehicle more quickly and reduce the strain on your AC system.

Side note: If your car has been sitting in the sun, it’s better to roll the windows down and turn off recirculation for the first minute or so. This allows the superheated air inside to escape before you turn the recirculation on.

Additionally, anytime you’re stuck in traffic—whether it’s summer or winter—be sure to use the recirculation feature. If you’re pulling air from outside, you’re also pulling in pollutants and carbon monoxide from the traffic around you. Studies show that using the recirculation feature can reduce the amount of pollutants entering your vehicle by 20% when you’re stuck in traffic!

A vehicle air conditioning system works by removing heat and moisture from the air inside the car, and circulating cool, dry air back into the cabin.
It consists of several key components;
1. Refrigerant: The refrigerant is a special fluid that circulates through the air conditioning system.
It changes from a gas to a liquid as it moves through the various components.
2. Compressor: The compressor is a pump that pressurizes the refrigerant and circulates it through the system.
3. Condenser: The condenser is a heat exchanger located at the front of the car, usually near the radiator.
It cools the refrigerant by dissipating heat to the outside air.
4. Expansion Valve: The expansion valve is a small device that regulates the flow of refrigerant into the evaporator.
5. Evaporator: The evaporator is located inside the dashboard and is responsible for removing heat and moisture from the air inside the car.
As the refrigerant flows through the evaporator, it absorbs heat from the air inside the car, cooling it down.
6. Blower: The blower is a fan that circulates the cool air from the evaporator into the cabin.
7. Control Panel: The control panel is located on the dashboard and allows the driver to adjust the temperature, fan speed, and other settings of the air conditioning system.

Why use my Air-Con in winter
One of the most common questions that we get asked at this time of year is:
Should I use my Air-Con in winter? The Answer to this is yes. We all know that Air-Con cools us down on a hot day but it also dries and filters the air inside your vehicle.
In winter if your windows mist on the inside do the following:
Set your fan speed to maximum
Put the A/C on
Set the temperature to maximum heat
Turn on recirculate
You can adjust your temperature down if you find the temperature to warm.
Once demisted you can also adjust your fan speed.
