AIR CONDITIONING SERVICE & REGAS 

Auto Air Con Servicing is now DH Auto Southwest

We service both R134a and R1234yf vehicles. 

 

Manufacturers recommend your car air con system is serviced at least every 2 years as it can lose up to 15% of refrigerant each year. Low refrigerant levels will mean the engine has to work harder to produce cold air resulting in decreased efficiency and increased fuel costs. It is important to maintain your air con system throughout the year to avoid any damage to components and to keep the system and seals well lubricated. It is also just as important to continue using the air con throughout the Winter, as the dry air it creates assists in quick demisting of the windscreen keeping you safer and improving your visibility out on the road. ​​

Our City & Guilds certified mobile technician is fully qualified in refrigerant handling and fully insured, covering Mid & West Cornwall so we will come to you. A service generally takes around an hour to complete, and includes the following:

  • Initial A/C System Check 

  • Refrigerant Recovery

  • Vacuum Pressure Test

  • Visual Inspection

  • System Regas (Recharge)

  • A/C Oil Top Up with Leak Detection UV Dye

  • Final A/C System Pressure Check

 

In some instances, we will need to carry out an additional Nitrogen Pressure Test prior to regassing if the system is completely empty of refrigerant or we suspect a leak. This is because it is a legal requirement to fully check an empty / potentially leaking air con system as air con refrigerant is a greenhouse gas and harmful to the environment. If this is the case we charge an additional fee for Nitrogen Pressure Testing prior to regassing. 

Complete your service with an Antibacterial Odour Treatment to remove bad odours and bacteria from the air con system.
