Concealed and discreet systems

We offer concealed or partially concealed systems that seamlessly fit into existing interiors, delivering cooling or heating through bespoke ceiling or wall diffusers. Our design experts will work with you to create the perfect system for your home.

Quality and service

We pride ourselves on the quality of our installations and overall service. With a planned maintenance contract in place, all of our air conditioning systems can benefit from a 5 year warranty.

Near silent operation

Using the latest air conditioning systems from the top Japanese manufacturers, our systems can be virtually silent during operation.

Offering a more cost effective solution than concealed systems, the wall mounted range now covers from standard to premium designer models in a variety of colours & finishes.

Wifi control

All of our systems offer the option to be controlled via an app on your phone from anywhere, any time.

We have used AAC on many occasions and recommended them to many of my family and friends. Excellent service very professional, They not only do commercial but they also do residential. Thank you so much Gary and his team

Abigail Rawling

We had our alarm installed about three months ago now. Right through from the quotation process to the installation and how the alarm has worked since has all been fantastic. I was keen to get the alarm fitted before we went away on holiday and AAC were super accommodating to make that happen. I cannot recommend them highly enough.

SMA Architects

Your years of expertise resulted in great advice resulting in a very neat installation. Alex was great to work with and he got on well with the roofer, coordination was very good with minimum fuss, all done by 3.00 pm on the day.

Leon Freris

Absolutely top professional expertise. Highly recommended.

Andy Summers

Great company and fantastic staff, Alex really went the extra mile, had the perfect install for my requirements. I’m so happy I will now be using them again to install AC at my work location.

Suzanne Finighan

Dave and the team installed an air conditioning unit in our bedroom and I’m so pleased with it. The unit is both modern and quiet. At every stage of the process the service was excellent so I wouldn’t hesitate to recommend AAC.

Joanna Taylor

I had a great service from this company they were efficient, personable and highly professional. Prices are reasonable and the installation on the day was delivered by 2 really charming people who cleared up where polite and explained things all through with me. Highly recommend to anyone looking for AC installation.

David Jaye

We engaged AAC to install air-conditioning at our house, and we were absolutely delighted with the work and the excellent after sale service. They were extremely efficient and the installation went like a dream. I am more than happy to recommend them for all your air conditioning requirements.

Simon Sherrard

Excellent service. Creative solution. The installation was clean, tidy and excellent. We wanted it installed in our bedroom, so it needed to be quiet and the unit is almost silent. We left Dave and his boys to do the installation whilst we were away on holiday. They came on time, they did a superb job and left everything spotless. I cannot recommend more highly

Chay Smalls

I had an Air Con unit installed in to my loft. Great service from the sales man Dave where he got everything in place for the fitter to fit the unit. They were reliable and friendly where their prices were reasonable as well. Would use again.
