A heat-recovery ventilator typically lasts 20 years. However, usage, maintenance and environmental factors can shorten or extend its lifespan.
Average lifespan of a heat-recovery ventilator
Heat‑recovery ventilators often last around 20 years before motors or heat exchangers deteriorate.
What affects how long a heat-recovery ventilator lasts
The lifespan of a heat-recovery ventilator depends on factors such as air quality, filter maintenance, operating hours and installation quality. These elements influence wear and can either extend or reduce its typical life.
Signs a heat-recovery ventilator needs replacing
Common signs that a heat-recovery ventilator is nearing the end of its life include reduced airflow, inefficient heat exchange, noise or fault codes. Noticing these cues helps you plan for replacement.
How to make a heat-recovery ventilator last longer
To extend the life of your heat-recovery ventilator, follow the manufacturer’s maintenance recommendations. Regular cleaning, proper usage and timely minor repairs can help it serve longer.
When replacement is necessary
If your heat-recovery ventilator shows persistent failures, safety issues or is beyond its typical lifespan, replacing it with a new model is usually more cost‑effective than repeated repairs.
