I was recommended to Matt by a neighbour who is also an established contractor who used Hamilton on his projects this was reinforced by 2 other neighbours who sung praises of Matt and his team.he couldnt have been more professional with precise quote and assurances on care of home decor etc ..Matts superb team installed 4 internal units and single Daikin condenser unit in 2.5 days the competence ,politeness and meticulous attention to care of furniture and decor was unparalleled and the work was so neat and tidy despite working in very confined loft space.I couldnt recommend Hamilton and its superb team more strongly !

I love this company! They took over from my old air-con company who had retired. They gave me honest, specific advice and went above and beyond to help sort out the issues. Great to deal with and I now consider them my go-to company and I hope to become their favourite client! Thanks Matt and Steve.

Recently installed a full hidden ducted air conditioning system. The team at Hamilton Air Conditioning worked with me, guiding me on the best choices and equipment for my needs and were super knowledgeable. The installation team were extremely professional and tidy and the final finish is perfect. Thanks!

Hamilton Air Conditioning was recommended to me by an existing customer that has very high standards. I was very impressed with the work carried out by Hamilton A/C - the work is excellent and the installation team was efficient and very tidy. Matt and his team did what they said they were going to do when they said they were going to do it and that is a rarity! I cannot recommend them highly enough.

Matt and the installers were an absolute pleasure to deal with from my initial enquiry to completing the fitting out of my air con unit. I couldn't be more positive about my experience with this company. Truly professional and the unit works beautifully.

We contacted 11 companies to install an AC unit in a loft conversion. Hamilton Air Conditioning was by far the most professional, punctual, and fast to reply to all the communications. The final result was excellent and the pricing was very competitive and totally worth it.
