Air Exchanger Maintenance
An air exchanger helps refresh indoor air by exhausting stale air and bringing in fresh air. Over time, dust and debris can build up on the filters and accessible components.
Professional maintenance helps maintain effective airflow and keep the system operating properly. We tailor the work to the unit's configuration and the manufacturer's recommendations.
Why maintain your air exchanger?
When filters or air passages become clogged, airflow may decrease and the unit may have to work harder. Periodic cleaning removes visible buildup from accessible areas and provides an opportunity to check the unit's overall condition.
Maintenance frequency depends on how the system is used, the home's environment and the manufacturer's instructions.
What our maintenance includes
The work depends on the unit's configuration and which components are accessible.
1. Initial inspection
We examine the overall condition of the air exchanger, filters, air intakes and accessible components before cleaning begins.
2. Filter and core cleaning
We clean the filters or recommend replacing them when they are too worn. We service the core when it is removable and washable, following the manufacturer's instructions.
3. Cleaning accessible areas
We remove dust and debris from accessible compartments, grilles, intakes and outlets. We also check the condensate pan and drain when present and accessible.
4. Reassembly and final check
After reassembly, we check the unit's general operation and the airflow perceptible at accessible openings.
Signs to watch for
- Weaker airflow than usual.
- Visible dust buildup on filters or grilles.
- Persistent odours while the unit is running.
- Excessive condensation or unusual noise.
These signs do not, by themselves, identify the cause, but they may indicate that an inspection would be useful.
