Heat Recovery Units (HRUs) are designed to improve indoor air quality and energy efficiency by extracting stale air and supplying fresh, filtered air—while recovering heat that would otherwise be lost. They’re commonly used in commercial buildings, schools, residential blocks, and healthcare environments.
To keep HRUs operating efficiently, regular maintenance and testing are essential. Without proper servicing, filters can become clogged, fans may underperform, and heat exchangers can fail—leading to reduced air quality and higher running costs.
Our HRU servicing includes:
- Cleaning or replacement of filters
- Inspection and cleaning of heat exchangers
- Fan, motor and sensor checks
- Testing airflow rates and system balance
- Verifying control settings and overall functionality
