Aircon Smell or Blocked Pollen Filter? Cleaned in Slough
If your aircon smells like wet dog, gym socks or a damp cellar the first time you turn it on each morning, that is bacterial and fungal growth on the evaporator behind your dashboard. Air-freshener trees do nothing for it. We do a proper antibacterial treatment plus pollen filter replacement at our Slough workshop, and it makes an immediate difference you can smell on the drive home.
Drivers across Slough and Berkshire often book this with their summer re-gas or annual service. The two go together, because the same damp evaporator that grows bacteria is also where condensation builds up after every cold start. We do it cleanly, properly, and fixed price.
Why your aircon smells (and why air fresheners do not fix it)
Your aircon evaporator is a cold metal grid behind your dashboard. Moisture from the cabin condenses on it every time you run the system. That moisture, plus dust, pollen and skin cells from the cabin, creates an ideal environment for bacteria and mould. Switch off the engine, the evaporator stays damp, the colonies grow. Switch the aircon back on tomorrow, you smell the breath of those colonies blasted into your face.
Air fresheners just sit on top of the smell. They do not kill the source. An antibacterial treatment kills the colonies on the evaporator itself, and a fresh pollen filter removes the dust load they were feeding on. That is why the smell stays gone.
What our antibac aircon clean includes
- Full system antibacterial bomb treatment. atomised cleaner pulled through the evaporator and ducting with the fan running. Reaches every surface
- Fresh OE-spec pollen filter (cabin filter). we use the correct part for your specific car. Most Slough customers have not had it changed in 4 years
- Vent and duct freshen. scented final pass through the system, neutral fragrance, not a chemical assault
- Evaporator drain check. a blocked condensate drain is why the moisture sat there in the first place. We clear it
- Test drive and final smell check. we drive it ourselves to confirm before handover at our Berkshire workshop
Combine it with a re-gas and save
Almost every Slough customer who books a summer aircon re-gas also books the antibac clean and pollen filter at the same time. Doing them together saves time on the bench and we discount the combined price. One visit, cold and fresh aircon for the year ahead.
Hay-fever season around Slough and Berkshire makes a fresh pollen filter even more worthwhile. The factory filter is good, but only when it is not five years old and clogged with M4 grime. Honest pricing on WhatsApp before you commit.
