Is Your Rental Heatwave-Ready? A Summer Survival Checklist

Australia's Summers Are Getting Hotter

The 2024-25 summer saw record-breaking temperatures across multiple states. For renters and owners alike, the question is no longer "will there be a heatwave?" but "how many days above 40°C will we get?"

An unprepared rental property isn't just uncomfortable during a heatwave — it can be dangerous, particularly for elderly residents, young children, and people with health conditions.

For Renters: Your Heatwave Checklist

Before Summer - [ ] **Test your air conditioning** — does it cool effectively? Report issues now, not during a 42°C day - [ ] **Check window seals** — gaps let hot air in and cool air out - [ ] **Identify your coolest room** — this is your retreat during extreme heat - [ ] **Buy a thermometer** — knowing your indoor temperature helps you make decisions

During a Heatwave - [ ] **Close curtains and blinds** on sun-facing windows from early morning - [ ] **Use fans strategically** — fans don't cool air, but they cool skin through evaporation - [ ] **Open windows at night** if the outside temperature drops below inside - [ ] **Stay hydrated** — drink water regularly even if you don't feel thirsty - [ ] **Know your nearest cool space** — library, shopping centre, community centre

After a Heatwave - [ ] **Document any issues** — did the AC fail? Were certain rooms unbearable? - [ ] **Report to your landlord** in writing if cooling is inadequate - [ ] **Check for heat damage** — warped window frames, expanded door frames

For Owners: Preparing Your Property

Quick Wins (Under $500) - **Install reflective window film** — reduces heat gain by up to 70% - **Add door snakes and weather stripping** — stops hot air infiltration - **Service air conditioning** — a dirty filter can reduce efficiency by 30% - **Install external shade** — awnings or shade cloth on west-facing windows

Medium Investment ($500–$2,000) - **Ceiling insulation** — the single most effective thermal upgrade - **Ceiling fans** — use 90% less energy than air conditioning - **External blinds or shutters** — far more effective than internal blinds

Major Upgrades ($2,000+) - **Split system air conditioning** — essential in most Australian climates - **Roof ventilation** (whirlybirds or solar fans) — reduces roof space temperatures by 15-20°C - **Double glazing** — significant improvement for older properties

How PropLedger Scores Thermal Comfort

Our Thermal Comfort module considers: - Type and condition of heating/cooling systems - Insulation presence and quality - Local climate data (average summer max, heatwave frequency) - Building type and construction era - Window orientation and shading

A property with no cooling in Western Sydney (average summer max 35°C+) will score very differently from the same property type in Hobart. Our suburb-level benchmarking ensures scores are relevant to where you actually live.

Both Parties Benefit

Owners who invest in thermal comfort see: - Lower vacancy rates during summer months - Fewer emergency maintenance calls - Happier tenants who stay longer - Higher property valuations

Renters who check thermal comfort before signing a lease avoid: - Surprise energy bills from running inadequate cooling 24/7 - Sleepless nights in poorly insulated bedrooms - The stress of dealing with a heatwave in an unprepared home
