What research are the recommendations based on?

Our recommendations are built on authoritative Australian sources: the Australian Government's YourHome guide (yourhome.gov.au) for passive cooling principles, the National Construction Code (NCC) climate zone classifications, CSIRO housing research on thermal comfort, and NatHERS energy rating guidelines. Product recommendations feature items rated by CHOICE and verified on ProductReview.com.au.

Is CoolMyHouse really free?

Yes, completely free with no catches. You get personalised recommendations, a PDF action plan, and shareable results. We don't sell your data. Some product links are affiliate links (we may earn a small commission if you purchase), but this doesn't affect which products we recommend.

I already have air conditioning. Will this help me?

Absolutely! Many of our highest-impact recommendations help you use your existing AC more efficiently. We'll suggest strategies like optimising your ducted zone controls, pre-cooling before heatwaves, using ceiling fans alongside AC (which lets you set the thermostat 2-3°C higher), and reducing heat gain so your AC doesn't work as hard.

We've got you covered. When you select 'rent', we automatically filter to non-permanent solutions: portable evaporative coolers, removable window film, internal blockout blinds, door draft stoppers, and behavioral strategies like night purging and cross-ventilation.

Does this work for apartments and units?

Yes! While some recommendations are house-specific (like roof ventilation), many apply equally to apartments: window film, internal blinds, ceiling fans, sealing air gaps, cross-ventilation strategies, and portable cooling options.

What about two-storey homes?

Two-storey homes have unique challenges - heat rises, making upper floors significantly hotter. We provide specific recommendations: ensuring adequate ceiling insulation, installing ceiling fans on the upper floor, using stairwell doors to contain cool air, and optimising ducted AC zones.

How much can I actually save?

Typical Australian households spend $600-1,200/year on cooling. Our users commonly save 30-50% by implementing high-impact recommendations. External shading on west windows can save $100-250/year, ceiling fans used with AC can save $100-300/year, and proper ceiling insulation can save $180-400/year.

What makes west-facing windows so critical?

The afternoon sun (1-6pm) hits west-facing windows at a low angle, penetrating deep into rooms. A large unshaded west window can add 1-2kW of heat - equivalent to running a bar heater! External shading blocks 80% of heat before it enters, while internal blinds only block 20-30%.

How do climate zones affect my recommendations?

Australia has 8 distinct climate zones, and strategies that work in Perth can fail in Darwin. In hot-dry climates (WA, SA) with humidity under 40%, evaporative cooling is excellent. In hot-humid climates (QLD, NT) with 60-80% humidity, evaporative cooling is ineffective - you need refrigerative AC instead.

Can I trust the product recommendations?

We only recommend products that are highly rated by Australian consumers (4+ stars), readily available (Bunnings, Amazon AU), and appropriate for your situation. Some links are affiliate links, but this never influences our recommendations.

Can I share my results?

Yes! You can share via a unique link (which includes your assessment data so others see your specific recommendations), get a detailed PDF report emailed to you, or print the page.

Frequently Asked Questions

Do I need air conditioning in Hobart?

Hobart has Australia's mildest summers, with averages rarely exceeding 22°C. Most homes manage well with ceiling fans, cross-ventilation, and external shading. However, climate change is bringing more hot days (30°C+), so a small split system in the main living area is worth considering for occasional use.

Why does my Hobart home overheat in summer?

Many Tasmanian homes are designed primarily for heating and can trap heat in summer. Common issues: dark roofs absorbing heat, insufficient roof ventilation, large north-facing windows without shading, and heavy thermal mass that stores daytime heat. External shading and roof ventilation make a big difference.

What cooling solutions work best for Hobart?

Given the mild climate, focus on passive strategies: 1) External shading on north and west windows, 2) Ceiling fans (effective up to 30°C), 3) Night purging (open windows overnight), 4) Cross-ventilation during cool periods. A small 2.5kW split system is adequate backup for the hottest days.
