Is motor failure covered by warranty?
Motor failures within the warranty period (typically 5 years) are usually covered. Check your warranty documentation or contact ROMA Heating for verification.
How long does motor replacement take?
Motor replacement typically takes 2-4 hours depending on the HRV model and motor accessibility. Our technicians carry common replacement motors for same-day service.
Can I temporarily use my HRV with one motor not working?
No, operating with one failed motor creates an imbalanced system and can cause additional damage. The system should remain off until repairs are completed.
