Ventilation Contractors | AAC



Ventilation Installation

A managed supply of fresh air in offices is vitally important. Not only does this improve productivity and efficiency but it helps create a more comfortable working environment and quite often is fundamental in achieving Building Regulations approval.

We can install a ventilation system which constantly provides fresh air and removes airborne contaminants.  Discreet grilles are placed in the most optimum places of the building in order to create the most energy efficient system.

Heat Recovery Ventilation

90% of what we install today is based on heat recovery ventilation. Assuming the space is heated and /or cooled, the HRV system uses the stale heated or cooled air to pre heat or pre cool the incoming fresh air.

By using this heat recovery method it is often possible to recover 80% of the heating or cooling that you have already paid for rather than simply disposing of it to atmosphere. The result is very low running costs and very low maintenance costs and a very pleasant and fresh environment to live or work.

Save money and do your bit for the environment with heat recovery ventilation from AAC.

Because our heat recovery systems regain up to 80% of the energy from their extract airstream, your carbon emissions are dramatically reduced.

Our most popular heat recovery ventilation system is the crossflo heat exchanger. This system transfers energy from one air stream to the other without any cross-contamination.

We install heat recovery systems by the following manufacturers:

• Daikin
• Mitsubishi Electric
• Vent Axia
• Soler & Palau

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.
