A air exchanger typically lasts 15 years. However, usage, maintenance and environmental factors can shorten or extend its lifespan.
Average lifespan of a air exchanger
Air exchangers generally last around 15 years before fans or controls wear out.
What affects how long a air exchanger lasts
The lifespan of a air exchanger depends on factors such as operating hours, filter maintenance, moisture levels and installation quality. These elements influence wear and can either extend or reduce its typical life.
Signs a air exchanger needs replacing
Common signs that a air exchanger is nearing the end of its life include reduced airflow, noise, fault codes or ineffective ventilation. Noticing these cues helps you plan for replacement.
How to make a air exchanger last longer
To extend the life of your air exchanger, 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 air exchanger 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.
