Improving the efficiency of an existing HVAC system is often a smarter investment than full replacement. ambientAIR assesses existing systems and recommends targeted energy upgrades that reduce energy consumption, cut running costs and extend the life of the equipment.
Working with retail chains, gyms, restaurants, hotels and commercial premises across the UK, the ambientAIR team delivers HVAC energy upgrades that deliver measurable results without the disruption and cost of a full system replacement.
Replacing old centrifugal fans in air handling units with Electronically Commutated (EC) fans is one of the most effective HVAC energy upgrades available. EC fans use variable speed control to match airflow to actual demand, reducing power consumption and improving overall system performance
Modern HVAC control systems can significantly reduce wasted energy by intelligently adjusting temperatures, airflow and operating schedules based on occupancy and demand. Upgrading to advanced controls ensures the HVAC system runs only when needed and at the right capacity. Advanced control upgrades can include:


Replacing electric heat banks with more efficient heating solutions such as gas burners or commercial heat pumps can dramatically reduce energy costs, particularly in large commercial and industrial applications. Heat pumps are particularly effective for commercial buildings working towards decarbonisation targets, delivering efficient heating while reducing reliance on fossil fuels and cutting carbon emissions.
Every HVAC energy upgrade project starts with detailed energy calculations. ambientAIR provides clear analysis of potential energy savings and return on investment for any proposed upgrade, helping businesses make informed decisions about which improvements offer the best value.
Energy calculations cover:
Including retail chains and supermarkets, gyms and leisure centres, restaurants and hospitality venues, hotels, offices, warehouses, schools and universities, healthcare and medical centres, care homes and shopping centres.
