Best Sellers FAQs

What’s the difference between “best sellers” and “featured”?

Best sellers are the items most frequently purchased across the store over time. “Featured” is curated (you choose what to push). For shoppers, best sellers are usually the safest starting point because they reflect what tradies are actually using day-to-day.

How fast do orders ship?

Dispatch is typically 1–2 business days (Mon–Fri), excluding public holidays. Freight time varies by metro vs regional. For full details and carriers, see the Shipping & Returns page.

Do I need an ARCtick licence to buy recovery/charging gear?

Buying a tool isn’t the same as being authorised to perform regulated refrigerant work. If you’re handling fluorocarbon refrigerant or doing work that could release refrigerant, you generally need a current Refrigerant Handling Licence. Use ARCtick’s guidance to confirm your obligations.

Which products help reduce running costs for customers?

Regular maintenance matters: clean filters/coils, correct airflow, and proper commissioning. Government guidance recommends choosing efficient models and maintaining systems so they run effectively. Pair a cleaning kit with good commissioning practice for the best outcome.

What if something arrives faulty or damaged?

You’re covered by Australian Consumer Law consumer guarantees. If a product doesn’t meet those guarantees, a remedy may apply (repair, replacement, refund) depending on the issue. Follow the site’s Shipping & Returns process and keep photos if there’s transit damage.

 

HVAC/R Best Sellers are the products customers purchase most often across our store over time — a reliable starting point when you want proven, reorder-friendly gear for real job sites.

Use this page to stock up on the staples across evacuation & vacuum, recovery & charging, diagnostics, and aircon cleaning & maintenance. The list updates as buying patterns change, so if you’re building a kit from scratch, start with the “Shop by job” links below and then filter by brand and availability.

Dispatch & delivery: current dispatch timeframes and freight options are listed on our Shipping & Returns page.

Quick buying guide (no fluff)

  • Evacuation: prioritise low leak potential (short, quality hoses + proper fittings) and verify with a micron reading.
  • Cleaning: match kit size to access and drainage control; follow product directions for coils and fan wheels.
  • Recovery work: match your machine to the refrigerants and typical system sizes you service; keep filters and hoses clean to protect the unit.
  • Diagnostics: buy once—good instruments pay for themselves in faster fault-finding and fewer return trips.

Compliance note (Australia)

If you’re doing work that involves fluorocarbon refrigerant, or RAC components that carry the risk of refrigerant being emitted, you generally need a current Refrigerant Handling Licence. Check ARCtick guidance for your obligations.
