Air con not blowing cold air?

Don’t wait until the next heatwave. Book your A/C regas and stay cool on the road.

After recharging the system, we check the cooling performance to make sure everything is working exactly as it should. The result: nice cold air, and comfortable driving on every journey.

“Took my car there to have air con regassed. He was mega helpful and got the job done at an excellent price.”

“I’ve been bringing my car (Kia Rio) here in the past for routine servicing and a minor repair, and Dariusz done a fantastic job. So, when I recently started having serious transmission problems, I knew exactly were to go. Once again, he didn't disappoint. Dariusz was incredibly professional, diagnosed the issue quickly, and fixed everything beautifully. The car runs smoothly now and feels as good as new. It’s hard to find a mechanic you can fully trust, but Dariusz is the real deal especially on Honda cars (I brought KIA Rio for repair). Highly recommend him for everything from regular maintenance to major repairs!”

About the garage

A family garage you can trust with your car

Ace Auto Works is family owned. Dariusz and Emilia Lukasiewicz are its directors, and it’s Dariusz who works on your car. Some of our customers have been bringing their cars to him for years.

We’re a small local business at Brigade House on Alington Road, St Neots, with our own dyno in the workshop. Servicing, repairs, diagnostics, air con and remapping all happen under one roof.

Customer feedback means everything to a small local business. If we’ve worked on your car recently, we’d really appreciate a Google or Facebook review.
