HVAC technicians use thermometers frequently to control the change in temperature. Temperature controls if a refrigerant needs to be added or if a piece of tackle is working properly. The thermometer used by HVAC technicians is a particular tool and is much different than the thermometer that pays a person for fever. It is important that the HVAC technician has a precise thermometer because their job is contingent on it. We propose the Fieldpiece ST4 Dual Temperature Meter for accurate temperature readings.

Cordless Drill

HVAC technicians use battery drills on a regular basis. They need one that will be dependable and durable because it will be carried into lofts and into crawl spaces where the real work is done. You may be drilling a new hole to run wires in the secret or in the loft. Cordless drills can go anywhere and are not limited to a particular distance from an electrical opening. Our recommendation is the Makita cordless drill.


HVAC technicians are always wounding through disordered materials or cutting overhead. The Sawzall is used to cut through old condensers, drywall, sheet metal, pipes, or wood. The sawzall is ideal for wounding through different types of materials without altering power tools. Our reference for this tool is made by Makita.

The heavy duty postponement cord extends the electricity into the dreamy breaks of the loft or sheds light on the crawlspace area underneath the house.

Ordinary household cabling doesn’t stand up to the power load that HVAC technicians use for working power tools. The industrial-grade postponement cord is tougher than a household delay cord, and we propose the US Wire 74050 delay cord for use on the HVAC job site.

Tubing Cutter

Tubing cutters are used to cut pipes. During connection or overhaul of HVAC equipment, these cutters make the job well-organized. These are standard cutters that cut a diversity of materials. The DIAOSnx Mini Hand Miniature Tubing Cutter Tool is our proposal for use in tight spaces.

Don’t supervise the step ladder when you are packing your HVAC work truck. It is an important tool that you might not think you would need very often, but if you are working in the field servicing units and cleaning vents, you will likely need a step ladder several times during your work week. The Louisville Ladder L-3016-04 Fiberglass Stepladder can give you an extra four feet in height if you need it.
