The engineer who came to service my air conditioning unit, placed a red bucket into my bathroom wash basin to fill with water without asking. Unfortunately he broke the tap unit. At the time he admitted liability and was very apologetic, however they have since suggested he did not do the damage (which is totally untrue)
It's a shame they took this attitude as a simple written apology, and a commitment to re-train staff would have been enough. I was not even asking to have the tap fixed at that time.

Excellent service and assistance! Initially uncertain about whether to install two or three units in our property, we eventually opted for three after a brief delay. The team promptly arrived and executed an outstanding job! Despite the scorching July heat wave, they worked diligentlyI'm certain they shed a few pounds in the process! Once more, exceptional service and assistance throughout.

Steve and Scott from Delta Air Conditioning did an excellent job with our installationfriendly, professional, and highly organized. Gareth provided clear and helpful communication from the initial quote, making the whole process smooth. From quote to installation in just 2 weeks, we are very impressed and would highly recommend their services. Our new air conditioning system has left us very pleased indeed!

Delta have been great from start to finish. We have large solar gain in the front part of the house and last year's baking summer and the prospect that it's going to be a regular event meant we looked at AC.
Had 3 quotes and Delta were not quite the cheapest, but on the ball, good people with good advice & responsive. I mucked them about a bit over the install date, but they were very accommodating.
Steve & Ed have just installed 2 Mitsubishi 3.5kw wall units in 2 different rooms and were excellent about location and routing of pipework.

External Condensing Unit very neatly installed. Top guys, neat, enthusiastic, communicative, drink lots of tea. They even did the setup for the WiFi control of the units remotely - as it's definitely non-trivial! Top company & people and all 0% VAT rated!
