A controlled flow of fresh air is vital in offices and commercial spaces. Effective ventilation improves comfort, enhances productivity, and supports a healthier working environment. It also helps ensure compliance with Building Regulations.



At AAC, we install energy-efficient heat recovery ventilation (HRV) systems that supply fresh, filtered air while removing stale air and contaminants. By recovering heat or cooling from outgoing air, our systems reduce energy waste, lower carbon emissions, and create a healthier indoor environment with low running and maintenance costs.

A heat recovery ventilation (HRV) system supplies your building with a constant flow of fresh, filtered air while removing stale air and airborne contaminants. Discreet grilles are positioned in optimal locations throughout the property to deliver an efficient and unobtrusive system. Around 90% of the ventilation systems we install are HRV-based due to their energy-saving performance. By recovering the heat (or cooling) from outgoing air, the system preheats or precools the fresh incoming air, significantly reducing wasted energy.
The result is a cleaner, healthier, and more comfortable indoor environment with very low running and maintenance costs. HRV systems can recover up to 80% of the energy from the extracted airstream, dramatically lowering your carbon emissions and helping you save money on heating and cooling. Our most popular option is the crossflow heat exchanger, which transfers energy between airstreams with no cross-contamination, ensuring fresh, filtered air at all times.
We install heat recovery systems from trusted manufacturers including:
