Keeping air conditioning systems in good condition is a shared responsibility in rental homes. For landlords, a well-maintained system helps retain tenants and avoid costly repairs. For tenants, it means a more comfortable living space during Australia’s warmer months. Here are some practical tips to keep air conditioning units running efficiently in a rental property.
1. Understand Who’s Responsible
Before anything else, it’s worth checking the lease. In most cases, landlords are responsible for the upkeep of fixed air conditioning units unless damage was caused by tenant misuse. Basic maintenance like cleaning filters might fall to the tenant, while more technical servicing is usually the landlord’s duty.
2. Clean the Filters Regularly
One of the easiest and most effective ways to maintain an air conditioner is by cleaning the filters. Dirty filters reduce airflow and strain the system, leading to higher running costs and potential faults. Filters should ideally be cleaned every 2 to 3 months, or more frequently in summer or dusty environments.
3. Check Outdoor Units
Whether you’re a landlord doing routine inspections or a tenant keeping an eye on things, check the outdoor unit. Make sure it’s free from debris like leaves, dirt, or overgrown plants. Good airflow around the external system is key to its efficiency and lifespan.
4. Schedule Annual Servicing
Professional servicing once a year is essential. It helps identify wear and tear before it becomes a bigger problem and ensures the system is working at its best. Landlords should arrange this in advance of the peak summer season to avoid emergency breakdowns during heatwaves. Reliable local providers offer servicing for residential systems, with experience across a wide range of models.
5. Educate Tenants on Usage
Tenants should be shown how to use the air conditioning efficiently simple things like setting the right temperature (ideally around 24°C in summer), closing doors and windows when the system is on, and switching it off when not in use. These habits reduce energy use and strain on the unit.
6. Report Issues Early
For tenants, if something seems off, strange noises, reduced airflow, or leaks, report it promptly. Catching small issues early can prevent them from turning into major repairs. Landlords should respond quickly to avoid tenant discomfort or extended damage.
7. Include AC in the Property Condition Report
During entry and exit inspections, note the condition of the air conditioning system in the report. This sets expectations and helps avoid disputes over damage at the end of a tenancy.
Maintaining air conditioning in rental properties is a team effort between landlords and tenants. With regular attention and clear communication, it’s possible to keep the system running well and everyone comfortable through the seasons.
