AIR CONDITIONING
SERVICE & REGAS

Mobile Car Air Conditioning Service & Regas Specialist covering Cornwall - We Come To You! 

It is really important to keep your vehicle air conditioning system well maintained with regular air con servicing. 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 improving your visibility out on the road. ​

R134a and R1234yf Auto Air Con Regas 

Since 2017 vehicle manufactures have been required by law to use a new, more environmentally friendly car air con refrigerant gas known as R1234yf in all new passenger cars. This new car air con gas replaced the older R134a refrigerant which has been in use since 1995. Some manufacturers began using R1234yf as early as 2013, so there are a number of vehicles during the 4 year crossover using either gas. DH Auto Southwest can service & regas both R1234a and R1234yf vehicles, and we can help you identify which gas your car will need when you book an air conditioning regas if you're unsure,
