Many tenants in New Brunswick wonder who is responsible for replacing air filters in a rental home, and that question matters for health, comfort and maintenance obligations. This article explains how responsibilities are typically divided, what your lease may say, and simple steps tenants can take when air filters need replacement or cleaning. It covers landlord duties related to heating, ventilation and air conditioning (HVAC) systems, tenant tasks commonly expected in daily upkeep, and when to report problems. If you rent in New Brunswick, understanding these points helps you protect your safety, avoid disputes, and follow official processes when repairs or dispute applications are needed.
Who usually replaces air filters?
In practice, responsibility depends on three things: the lease terms, whether the filter is part of an appliance the landlord supplies, and whether replacement is needed as a result of normal use or tenant damage. Many landlords arrange periodic HVAC maintenance and replace filters as part of building upkeep; other landlords expect tenants to change disposable filters in-unit. Check your lease first and ask your landlord to confirm their expectation in writing.
Legal framework and official resources
New Brunswick tenants and landlords should follow the province's residential tenancy rules and the decisions of the official tribunal that handles disputes. The Residential Tenancies Tribunal handles disputes about repairs, maintenance and tenant responsibilities in New Brunswick [1]. The Residential Tenancies Act describes obligations for landlords to maintain heating and essential services and for tenants to take reasonable care [2].
Typical division of responsibility
- Landlord: maintain HVAC systems, ensure systems are safe and provide working heat and ventilation; replacements for built-in systems are usually the landlord's duty.
- Tenant: replace simple, disposable filters if the lease assigns that task or if the filter is easily accessible and intended for occupant maintenance.
- Lease provisions: written lease clauses that specify filter care are enforceable; keep a copy of any agreement about who replaces filters.
When to report and how to document problems
If a filter is clogged, causes poor heating or creates safety concerns (for example, strange smells or reduced airflow), report it to your landlord in writing and request repair or replacement. Take photos or short videos showing the filter or the problem as evidence and keep records of communication.
Practical steps for tenants in New Brunswick
- Check your lease and any move-in inspection report for written notes about who maintains filters.
- Contact your landlord or property manager to confirm responsibility and preferred filter type and size.
- Document the condition with photos and keep a dated log of messages and responses.
- If the landlord does not respond or refuses repairs, follow the tribunal application process and keep records for a dispute application [3].
When a repair request becomes a dispute
If the HVAC system fails because filters were not replaced, and the landlord refuses to act, you can apply to the Residential Tenancies Tribunal for an order requiring repairs or compensation. Use clear documentation and explain the health or habitability impact, such as loss of heat or increased mould risk.
