VALUE OF SERVICES PROVIDED

Check Systems for Leaks

                 An improper refrigerant charge can cause
                 compressor shut-down.
                 Refrigerant undercharge of only 10% can increase
                 operating cost by almost 20%

Clean Condensers Annually

                 Dirty condensers raises refrigerant pressure higher
                 than needed.
                 This condition will increase the electrical bill and can
                 cause compressor shut-down.

Install Oil In Reciprocating Compressors

Lubricate All Bearings

Improperly lubricated rotating equipment will
eventually fail.

Check All Electrical Controls And Starters

Adjust All Operating Controls

                Controls and safeties that do not function properly
                will increase
                operation cost and cause other components to fail.
                Worn contacts and loose wires can lead to a motor or
                compressor
                failure.

Adjust Or Replace Belts

Check Air Flow Conditions

                Loose belts decrease air flow, increase operating cost
                and shorten
                the compressor life. Belts crack and break with age.
                Reduced air flow will lead to compressor failure.

Check Amperage Draw On Compressors

Amperage higher than normal will cause motor failure
and expensive repairs.

Change Air Filters

Restricted air filters can cause the unit to run
continuously and eventually cause compressor failure.

Clean And Inspect Condensate Pumps

Clean Drain Pans And Drain Lines

                Dirt and algae can plug the condensate pump, drain
                pan and drain lines, which can cause expensive water
                damage.

Clean Evaporator Coil As Needed

                A dirty evaporator coil will decrease efficiency and
                increase operating cost. This is also a major cause of
                compressor failure.

Check Compressor Crankcase Heater

Crankcase heaters that don't work can lead to
compressor failure.
