What cordless tools does an air conditioning technician need?

An HVAC technician requires an 18V hammer drill, compact impact driver, cordless vacuum pump, automated flaring tool, and a refrigerant press tool. These core battery tools replace manual gear, eliminating extension leads on domestic roofs and ensuring consistent, repeatable tube connections that comply with AS/NZS 5149.2 standards.

Are cordless vacuum pumps good enough for split system installations?

Yes, modern 18V cordless vacuum pumps pull down past 50 microns reliably on residential split systems and light commercial systems. They eliminate trailing 240V leads across tin roofs, reducing electrical risks under AS/NZS 3000. Running dual-stage designs, a 5.0Ah or 8.0Ah battery provides ample runtime for thorough system dehydration.

Which battery platform is best for HVAC and refrigeration in Australia?

Milwaukee M18 and Makita 18V LXT lead the Australian market due to deep HVAC-specific trade tool support. Milwaukee offers dedicated press tools and vacuum pumps natively, while Makita features cordless vacuum pumps and rebar cutters. Other brands require third-party, battery-adapted equipment like Navac or Value to match specialised HVAC capabilities.

Is a cordless flaring tool better than an eccentric manual flaring bar?

A cordless flaring tool consistently produces standard 45-degree flares with uniform wall thickness and zero operator fatigue. Manual flaring carries higher risk of uneven shoulders or over-thinning copper pipe, causing costly refrigerant leaks under high R32 operating pressures. Battery units complete a factory-grade flare in under twenty seconds.

What size core drill do you need for air conditioning pipework?

A dedicated heavy-duty cordless rotary hammer drill running a 65mm to 75mm diamond or TCT core bit is standard for residential split penetrations. This diameter cleanly clears insulated pair-coil, drain hose, and interconnecting electrical cable through double brick or core-filled block without blowing out the external render.

Which HVAC cordless tools require high output batteries?

Rotary core drills, reciprocating saws, vacuum pumps, and large angle grinders demand high-current battery packs to prevent thermal stalling under heavy loads. Utilising 8.0Ah to 12.0Ah high-output batteries ensures sustained motor amperage during deep brick coring, while standard 3.0Ah to 5.0Ah packs suffice for impact drivers, flaring tools, and digital manifolds.

Air-conditioning and refrigeration work is going cordless fast — tools that used to be manual or need mains power, like flaring tools and vacuum pumps, now run off the same batteries as your drill. That makes platform choice especially important for this trade.

The core kit

Drill/driver and impact driver — mounting brackets, fixing units and general work.

Cordless flaring tool — repeatable, consistent flares without the manual effort.

Cordless vacuum pump — evacuation without dragging mains power onto the roof or into the ceiling.

Press tool — for pressed refrigeration and water fittings where used.

Core drill — clean wall penetrations for pipe runs; a high-draw tool.

Reciprocating saw and angle grinder — cutting and access.

Digital gauges, work lights and fans round out many kits.

Match batteries to the load

The core drill and vacuum pump are the hungry tools — give them high-output batteries and brushless motors. Drills, drivers, flaring tools and gauges are fine on all-round or compact packs. Size the set with How Many Tool Batteries Do You Actually Need?.

Enter the platform sensibly

Because several HVAC tools are platform-specific, let the speciality tools help choose — confirm your shortlist makes the flaring tool, vacuum pump and press tool you want, using Which Cordless Battery Platform Should You Commit To?. Then enter with combo kits and add the rest as skins — Combo Kit vs Tool-Only Skins.

Kitting out or upgrading a platform

Committing to a platform is a real investment, because the batteries — not the tools — are the recurring cost over the years. If you are setting up a new platform, replacing a stolen kit, or standardising your crew onto one system, spreading the cost with equipment finance can keep your working capital free for jobs and materials. It is worth weighing the repayment against the runtime and downtime you save. See how tool-and-equipment finance works for sole traders and small crews on our equipment finance guide.

Old batteries and retired tools

Flat or ageing batteries still have value, and dead lithium-ion packs must never go in general or recycling wheelie bins — damaged cells are a genuine fire risk in trucks and transfer stations. Recycle them free through the national battery scheme at B-cycle drop-off points. When you are moving platforms, working "skins" (tool-only units) that no longer suit you can often be sold or traded rather than binned. Before you buy your next skin, it is worth knowing where tool prices are heading — our Tool Price Index tracks how cordless tool prices are moving.
