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 work environment and quite often is fundamental in achieving Building Regulations.

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.

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 precool 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

What our clients have to say

“Thank you for all your help and advice with our amazing domestic air conditioning unit. From our first meeting you explained everything clearly, showing where the installation would sit, and how it would work. You were the only company who told us that only 5% VAT was applicable to certain types of heating and cooling  units.  The engineers who did the installation were lovely and they took great pride in their workmanship.  We are delighted we chose AAC. We have, and will continue to recommend you.  We also strongly believe we have received good value for money. Many thanks again.”

Jackie Finer, Bricket Wood
