Basic Refrigeration Preventive Maintenance
Formulating a daily, weekly and monthly preventative maintenance checks and services schedule will allow for proactive system maintenance and familiarity with your system.
Some common maintenance checks include:
1. Clean evaporator and condensing coils every 30 days. Some professionals suggest that only soap and water be used, harsh chemicals should be avoided. Another method is to use three parts water to one part de-greaser mixture with a soft-bristle brush. Be sure to rinse thoroughly with water when you are done cleaning. Keeping a spray bottle convenient for flushing, and the residue is easily mopped away. NOTE-when cleaning condenser coils, be sure to always scrub with the coils-up and down. Never, scrub side to side, as it will damage the coils.
2. Clean fan blades to reduce drag and excessive wear. You will need to disassemble the fan cover and wipe it down as well. A common de-greaser solution is fine for this. Be sure to rinse thoroughly when done. Have a service technician perform calibration checks to insure the fan motor is running at an optimum RPM level.
3. Insure all condensing units are clear of all trash and weeds that may be wrapped around the condensing unit intakes located outside in order to maintain adequate airflow and optimal performance.
4. After cleaning, be sure to lubricate door hinges annually. Cooler doors that do not operate properly can cause a vacuum causing the unit to have to work harder to maintain the proper temperature. Spring hinges that automatically close are ideal for high-traffic walk-in coolers and freezers.
5. Inspect for decay in the insulation on suction lines between the condensing unit and evaporator coil. This can cause condensation and water damage. Replace decayed section immediately.
6. Check door sweep for tears. Periodically have a professional inspect electrical control connections to ensure they are tight. Loose wires can result in high amperage, which will increase the amount of energy used by the unit and may also pose a fire risk.
7. At least once a year, get a professional technician at American Services to check to ensure that drain lines are clear of debris.
