Cool Air - Warm Service

General Air Conditioning Questions

Most systems perform best with servicing every 6–12 months. Sydney’s salt air, dust, humidity and summer heat place extra pressure on coils, filters and electrical components, so regular maintenance helps you avoid breakdowns and high power bills.

For commercial systems or properties running AC for long hours, more frequent servicing may be recommended.

It depends on the size of your property and how you use each space. Split systems suit smaller homes and single rooms, while ducted air conditioning provides whole-home temperature control with zoning options. Apartments typically require compact, strata-approved systems.

If you’re unsure, book a site assessment and we’ll recommend the most efficient setup for your property layout.

Yes. We work with homeowners, builders and architects throughout Sydney to design systems that complement new layouts, electrical plans and insulation levels. We also install systems during renovation stages to ensure clean, efficient ducting and long-term performance.

Yes. Strata committees and heritage-listed properties often require documentation on noise ratings, placement and visual impact. We supply all technical specifications needed to streamline your approval.
