Amazing Service ⭐️⭐️⭐️⭐️⭐️
Posted 6 days ago
Wow…..we called on Diamond AC on Christmas Eve as we had no heating they were with us in under an hour and resolved in ten minutes with what was embarrassingly a fault on our part in not using it in the right mode but that aside the service and response was unbelievable and we couldn't recommend Andy enough. We will be saving his number for any future problems in the future.

Great service from Andrew and his team at Diamond Air Conditioning. Very polite and courteous. Arrived exactly on time, completed the work to a high standard and left the place spotless. Andrew also managed to fit us in at short notice which was much appreciated. Thank you.

Excellent service provided by Andy and his team. They were happy to work around my availability (booked to do job on a Sunday morning). I am very happy with the solution they provided and would highly recommend Andy's services to others.

Home air conditioning

Andy and his team installed a Mitsubishi air conditioning system at our home. A very easy process and good experience. I would certainly recommend Diamond.

Quality professional service
Posted 14 November 2025
Andy came to service my domestic a/c unit and quickly identifed long-standing problems. He returned the next day to rectify and ensure that the system was working better than the original installation (not by Diamond a/c). Super quality, friendly and quick service . I can see why he gets such excellent reviews. Would happily recommend.

A very good company and respectful of our home.
Posted 01 November 2025
Diamond AC attended my home for a full service of 7 units and a very good job done cleaning and all the bad smells are now gone. Had a unit in my garden office I forgot to mention which they did at no extra cost for us. Will be booking in next year for sure. Andy and his team were very easy to deal with and so respectful of our home.
