AC Maintenance is perhaps one of the most common types of servicing offered by commercial air conditioners. Flexible AC maintenance schedules offer a wide variety of advantages, and each schedule has two semiannual inspections to the same workplace or residence in the summer and fall months. During both visits, AC technicians perform a wide variety of key AC calibrations, checks, and inspections which include the following items:
The first part of the air-conditioning unit check involves visually inspecting all motor and electrical components of the air conditioning unit. The technician inspects all fuse and terminal connections on the electric motor, both starters and relays, as well as the electronic controls. When an AC failure is detected, the technician will open the circuit breaker for the affected system and then reconnect it. He may also recommend the option of an automatic cooling fan to help alleviate the inconvenience.
The next step in this AC maintenance schedule is performed when an AC failure is not noticed during the visual inspection. A non-contained heating and air-conditioning system should be shut down until the problem is corrected. The technician then replaces the heating element, modifies the thermostat, and switches the air-conditioning unit back on. By doing this, you prevent damaging your HVAC system by inadvertently setting it for an unnecessarily high or low temperature.
The third part of this maintenance program involves measuring the performance of the air conditioning system. This involves taking several measurements of the cooling performance of the outdoor unit, including both the indoor and outdoor temperatures and humidity levels. Peak Performance Meters is available from many HVAC equipment dealers to help identify poor airflow, condensation, and leakage throughout the HVAC system. AC maintenance technicians also measure the amount of heat lost through the windows and doors. By using a heat-loss meter, the HVAC technician can identify areas where the AC is losing heat that could improve peak performance. In addition to the heat meter, outdoor unit gauges can be used to monitor the condition of the outdoor unit.
Finally, AC conditioner maintenance appointments should include routine cleaning and repairs of the evaporator coils and condenser coil. These coils accumulate dust, debris, and moisture that eventually impact the operation of the heating and cooling unit. Cleaning and repairs of the coils will extend the life of the equipment.
AC repairs should be scheduled at least once a year, as long as they are taken care of properly. If a homeowner does not have an HVAC company, they should ensure that the unit is properly maintained regularly. If your unit has been damaged, it may be too late to save it, so it is important to contact a local HVAC contractor as soon as any problems become apparent.
