HVAC Maintenance

Buildings today need proper operating systems not only for people comfort but also for equipments. For example, all your telecommunications systems requires specific environment to operate properly. To achieve this, you need to have your HVAC systems always in top condition.

To prevent any problem for your HVAC systems, proper maintenance chart should be developed. And its always good to have a cmms software to implement the maintenance chart and also to keep track of all the maintenance activities.

HVAC Maintenance check should include

General Checks :

Thermostat : Check thermostat settings to ensure comfortable cooling and heating.

Electrical Connections : Check and tighten all electrical connections, loose and faulty electrical connections can be unsafe and also reduces lifetime for major hvac components.

Lubrication : Lubrication is a must for all moving parts, this not only reduces the noise levels but also improves the life by reducing friction and ensures smooth operation of moving parts.

Drains : Check drains for any blocks, a plugged drain may cause water damage and affects HVAC performance

System Check : Check system start, run and stop to ensure proper and safe functioning.

Cooling Checks :

Coils : Check and clean evaporator and condenser coils. Clean coils improve the ability to cool fast and saves energy.

Refrigerant : Check refrigerant level and adjust if needed. Maintain optimal level of refrigerant makes your HVAC system more efficient.

Blowers : Inspect and clean blower assembly (includes blower housing, blower wheel and motor). Airflow problems can reduce system efficiency

Heating Checks :

Gas or Oil : Check all connections, pressure, burners for leaks and cracks for safe and efficient running.

Using FacilitiesDesk cmms software maintenance module you can keep track of every HVAC system. You can also create multiple maintenance activity schedules along with checklists and safety tips to keep the system running effectively and efficiently.

Preventive Maintenance

Preventive maintenance is a systematic way of checking and repairing a asset, equipment, machine or vehicle. Asset life can be significantly extended by simply tightening screws, cleaning, lubricating and replacing parts that show wear. Most of the equipment manufacturers design a specific preventive maintenance checklists for maintenance professionals to follow when they take the equipment down for maintenance.

Preventive maintenance is usually outlined in instruction manual or maintenance checklist. In most of the preventive maintenance checklist the first step would be cleaning the exterior and interior of a equipment. Cleaning, lubricating and tightening are the three important steps in any preventive maintenance checklist.

Preventive maintenance ensures machines, equipments, assets and vehicles are kept in proper working condition. A major, expensive repair can be avoided by carrying out preventive maintenance activities at scheduled time intervals. Scheduling preventive maintenance will be easier when you have a cmms software implemented.

Implement a cmms software to keep track of preventive maintenance schedules for every machine, asset, equipment and vehicle. You can also prevent missing any preventive maintenance activity by uploading and maintaining the preventive maintenance checklists in CMMS software.

Lighting - Preventive Maintenance Checklist

• Inspect at regular intervals
• Check exterior lights to make sure cables aren't torn;
  
• All screws and hardware should be in place and working
• Replace gaskets to provide a better watertight seal.
• Replace burned-out lamps
• Ensure that each lamp has the same color temperature.
• Dust lamps and clean lens surfaces to enhance lighting performance.
