Air-con that's lost its cold means the gas has leaked out — and a regas without a leak test just delays the same problem. Drova vacuum-tests, leak-checks with dye, then regases with the correct gas (R134a or R1234yf) for your car.
Most cars need an air-con service every 2-3 years to keep the system efficient. A neglected system loses 10-15% of its gas a year through normal seal permeation — eventually it can't make cold air.
Drova covers Lincolnshire for mobile air-con work with the correct kit for both R134a (pre-2017 cars) and R1234yf (newer cars, more expensive gas). Pollen filters changed at the same time on most jobs.
R134a regas from £69 · R1234yf regas from £119. Includes vacuum, leak check, dye, weighed recharge and performance test. Leak repairs and parts (condenser, compressor) quoted separately after diagnosis.
Every 2-3 years on average. Modern systems lose 10-15% of their charge per year through seal permeation, so even a leak-free system needs topping up periodically.
R1234yf is the newer (lower global-warming) gas mandated on cars built from ~2017. It's around 5x the price per kilo of R134a and needs its own dedicated machine. Drova has both.
Usually low on gas — the condenser doesn't get enough air at low speed and the system can't shed heat. A regas + leak test sorts it.
Mould on the evaporator. Drova treats it with an anti-bacterial purge and fits a fresh pollen filter as part of the service.
