Best HVAC Tools

Best HVAC ToolsHVAC maintenance, repairs and new installations require the use of lots of tools. Some are commonly used by many trades, like a ladder, tube cutter, reciprocating saw, level and wire stripper, along with different kinds of snips, pliers, wrenches and screwdrivers. Depending on the exact work that’s being done, your technician might employ various specialized HVAC tools too, and here are some of the best:

Air Conditioner Gauges

Also called a refrigeration or manifold gauge, this tool is vital to measure refrigerant temperature and pressure during a new cooling system installation, or when coolant is being added to an existing system.

Vacuum Pump

Your technician may use a vacuum pump to remove contaminants like air and moisture from the refrigerant lines to prepare your cooling system for recharging.

Refrigerant Scales

Refrigerant scales allow a technician to measure the exact amount of refrigerant that’s added or recovered from your cooling system.


If your technician is investigating suspected airflow imbalances in your HVAC system caused by problems with the blower or obstructions or leaks in the ductwork, a manometer will likely be used to measure static pressure on the supply and return sides of the duct system.


If your cooling system isn’t dehumidifying properly, a wet and dry bulb thermostat called a psychrometer can measure the amount of moisture in the conditioned air. Two temperatures are taken with the psychrometer and the difference reveals how much humidity is being removed.

Clamp Meter

If there are suspected issues with your HVAC system’s electrical wiring, a clamp meter may be used to measure amps and volts to help a technician pinpoint the problem area.

Combustion Analyzer

A combustion analyzer is a sophisticated diagnostic tool used to assess the efficiency and safe operation of your home’s oil- or gas-burning furnace. The analyzer displays readings for oxygen, carbon dioxide and carbon monoxide as well as the flue temperature so a technician can then compare them against your equipment manufacturer’s specifications.
