Air conditioning specification, construction sequencing, and site preparation guidance — written for the Hills District, updated as conditions change.
Answers to what builders and site supervisors ask us most.
Every guide is written by Gabrielle Ebsworth (Head of Content, HVAC & Build Specifications) or Tom Radley (Site Supervisor Contributor) — both work directly with Hills District builds, not generic content writers.
Not currently — this site is deliberately focused on Castle Hill, Baulkham Hills, Kellyville, Dural, and Glenhaven, where conditions and council overlays are specific enough to warrant dedicated coverage.
New guides go up roughly twice a month, prioritised around seasonal timing (like air conditioning specification ahead of summer) and whichever pillar needs the most coverage at the time.
Yes — use the Contact page with your question, and we'll consider it for a future guide.
