Car Aircon Regas

Car Aircon Regas

As the summer season approaches and the days get hotter we find ourselves using the now ubiquitous car comfort feature…our vehicles car air conditioning. Something that can give us almost instant relief on those summer scorchers does, just like all other items on your car, require periodic maintenance so maybe it’s time for a car aircon regas?

As with many convenience tools that are part of our daily lives we seldom ponder what the car aircon actually is and why it needs to be regassed and have maintenance from time to time. Coolco AC specialises in car aircon regassing, keeping you cool on hot summer days.

What does a car aircon regas entail?

Here at Coolco our aircon regas starts with our technicians checking your vehicles system pressures. This is done to determine if the lack of cooling is in fact due to low refrigerant (gas) or another fault, be it mechanical or electrical. Once we are confident that the vehicle does need a aircon regas we will program our fully automated services stations to begin the process.

The car aircon regas cycle starts with a system recovery where all the remaining gas is evacuated from the system. Next the system is put under vacuum to allow any excess moisture within to be boiled off. This is a crucial step as moisture causes corrosion on the internal parts of your vehicle’s aircon leading to premature mechanical failure. The machine will then check for any FAST leaks by checking if the system can hold vacuum. If passed it will then inject compressor oil, leak detection ultraviolet dye & a full recharge of gas into the system. Now that the system has a complete charge of gas our technicians will test the car aircon system to identify and report any symptoms that may be of concern.

This initial process takes approximately 1 hour to complete and can be done while you wait. Please phone to check for availability during our summer season (October to April) to avoid disappointment. Click here to contact us.

The last step is for you to return with the vehicle after having used the now fully gassed aircon for a period of 2 to 3 weeks. Your return allows us to check for any SLOW leaks which is done by scanning the system for dye with our special ultraviolet light. If any leak is found a quote will be given for the work to be done. A leak detection scan can also be done while you wait in about 20 minutes.

BEWARE of those that will simply ‘top up’ the refrigerant in the A/C system by directly adding gas to the system using a bottle of refrigerant without following the procedure described above. This method is extremely risky as it typically leads to the system being over charged leading to excessive system pressures on very hot days. This coupled with the system not either being vacuumed or having oil added to the system is a major cause of premature component failure.

Rather leave it to the professionals at Coolco to ensure your car’s aircon is serviced correctly. We specialize in car air conditioning and are based in Montague Gardens, Cape Town. 


Proper Car Aircon Re-gassing Procedure:

1. Recovery
2. Re-cycle
3. Vacuum

4. First Stage Leak Detection
5. Add Oil
6. Add Dye

7. Add Gas to by mass according to Database of Machine or Sticker on vehicle.

Importance of using the proper car aircon re-gas procedure:

*Failure to carry out this procedure in this order can cause premature compressor failure.
