Make your equipment installation a breeze with these hand tools.  Cut sheet metal and copper tubing to size with our copper tubing cutter and sheet metal sheers.  In an air conditioning installation, copper tubing cutters are used to cut your line set the proper size (the line set runs between your air conditioning unit and evaporator coil and is used to circulate refrigerant). Making clean cuts in the copper tubing ensures a clean environment for refrigerant to circulate through. With a humidifier, the cutters are used to cut 1/4" copper water tubing.   Sheet metal sheers are used to make even cuts in the sheet metal used to house the evaporator coil - a major component of the air conditioning system. Sheet metal shears are used for humidifiers to cut the plenum hole and any attaching sheet metal pipe (if installing a bypass-type humidifier.)  Sheet metal is extremely sharp and should be handled with care.  Using the proper tools helps make the job both easier and safer.  Remember: most jobs are easy if you have the right tools!
