BMW Air Conditioning Repair in London

We regas and repair BMW air conditioning systems — both R134a (pre-2017) and R1234yf (newer cars) — with proper leak detection using UV dye or nitrogen pressure testing before we add a single gram of refrigerant.

If your BMW AC has stopped cooling, there is usually a specific leak — not just “low gas”. We find the leak, fix it, and then regas. Otherwise you are paying for gas to vent into the atmosphere.

Regas done properly

We vacuum the system to confirm it holds, pressure-test with nitrogen, then regas with the correct weight of refrigerant and compressor oil. Every step is measured.

Compressor and condenser

A seized compressor usually contaminates the whole system — compressor plus receiver-drier plus expansion valve plus flush, or the new compressor will fail again inside six months.

Frequently asked questions

  • How often does BMW air conditioning need a regas?

    Modern AC systems lose around 5% refrigerant a year through normal permeation. Every 3-4 years is typical. If your AC has stopped cooling suddenly, that is a leak, not gradual loss — we will find and fix it first.

  • What is the difference between R1234yf and R134a refrigerant?

    R1234yf is the modern, lower-GWP refrigerant fitted to most BMWs from 2017 onwards. R134a is used on older cars. They are not interchangeable — we have both.

  • Why does my BMW AC smell musty?

    Usually a blocked cabin filter and bacterial growth on the evaporator. A new pollen filter and an evaporator clean fixes it in an hour.
