Job location: SO51So pleased! Had the guys over on the Friday, originally was quoted 2 days. But after I said that I really needed the work done because I was having a garden party. They stayed on a few extra hours and came back early Saturday morning to finish off the work! Thank you again I will be recommending you to everyone I know!10 So happy! Would recommend!

Job location: SO51We recently had Diamond HVAC install air conditioning in our two bedrooms and living room and couldn’t be happier with the result. The whole process was smooth from start to finish and the installation was neat and professional. The engineer who carried out the work — I think his name was Matt — was friendly, tidy and explained everything clearly. The units work perfectly and have made a huge difference to the comfort of our home. Working night shifts I find I need a quick cool down, but on the brisk cold mornings, I use my phone and can have my bedroom warm for when I walk through the door.10 Had air con installed

Whole service was very efficient from the quote to installation. There was no pressure once quote was received and the price was very reasonable so we didn’t hesitate to use Diamond HVAC. They were very knowledgeable and the workmen were clean and tidy when installing our new aircon units in our house. Would highly recommend to friends and family. The units have been brilliant for quickly heating our home and also cooling when needed.Verified reviewerJob location: SO40
