Air Conditioning Maintenance and Safety Check

• Install gauges and check operating pressures.
• Check voltage and amperage to all motors with meter.
• Check temperature difference across evaporator coils – Evaporator coils become dirty because air filters only collection a portion of the particles
in the air. Even a small amount of dirt can decrease efficiency and increase operating costs. This is also a major cause of compressor failure.
Customer should replace properly sized air filter every month.
• Check for adequate refrigerant charge and leaks – A low or high refrigerant charge can easily go unnoticed and increase operating costs. An
improper charge can cause compressor shut down.
• Lubricate all moving parts – improperly lubricated rotating equipment will eventually fail.
• Check belt and adjust tension.
• Check filters – A restricted air filter can cause your air conditioning unit to waste energy and shorten compressor’s life.
• Check pressure switch cut-out settings.
• Check start capacitor and potential relay, if possible.
• Check compressor contractor.
• Check all wiring and electrical components.
• Check and adjust thermostat calibrations – Improperly calibrated thermostats allow the unit to run longer than necessary.
Every degree your air conditioner operates below 78 degrees can add 5-8% to the cost of cooling.
• Check condensing coil – Dirty condensing coils raise refrigerant pressure higher than needed, increasing your electrical bill.
• Check that condensate drain is open – Algae can plug a condensate drain which can cause expensive water damage.
• Turn exposed dampers to cooling position.
