Excellent installation of addition air conditioning units to join the others that were fitted by them. This company comes highly recommended. The team were very polite & clean and respectful of our home. Pricing was competitive we were kept up to date at all times. Andrew was quick to respond to questions. Outstanding workmanship. Absolutely delightful to deal with.

Had a slight issue with potentially a squirrel nibble of one of our a/c small pipes in the loft causing a leak onto the ceiling. Contacted Andy and Jim was there early the next morning to repair it. He even told us what to get to cover and seal the water stains. Amazing service as usual despite the fact the squirrel 🐿️ nibble wasn’t down to them. It’s important to me to know the level of service you get after an install and Diamond AC really are consistently excellent. Thanks guys.
