How Does Car Air Conditioning Work?
A sealed, high pressure system with a drier and an expansion valve, modern car & van air conditioning systems utilise a compressor to compress a refrigerant gas. A pump moves the gas through the air conditioning pipes. Over time the gas gradually escapes the system resulting in no cold air from the car’s interior vents. This is why your car’s air conditioning system needs re–gassing (recharging) and occasionally repairing & cleaning. Mostly just vulnerable to compressor bearing wear and leaks these days with minor maintenance modern air con systems are designed to generally out live the vehicle.

Why Do I Need Air Con Recharge?
Referred to as re–gas or recharge. Every year your car air conditioning system will lose 10–15% of its refrigerant gas. Without re–gassing & occasionally cleaning this eventually results in a build up of bacteria which grows into mould inside the systems pipes and evaporator. This is the source of bad odors which if left can result in allergies for the occupants. This is why you should get your air con recharge in Chesterfield regular, typically every 18 months to 2 years.
What If I Don’t Get It Re–Gassed Or Re–Charged?
Leaving your air conditioning without getting it recharged (re–gas) can ultimately end with your air conditioning system being financially not repairable due to excessive component wear. This means the cost to fully repair your air conditioning system is more than your cars re–sale value.
How Often Do I Need Air Con Re–gas?
What Your Car’s Manufacturer Says
