The HVAC serve many purposes in the commercial building, where it keeps the occupants in comfort conditions, keep healthy and secure and even improves the air quality. These systems have been typically installed in the buildings in compliance with the best regulatory practices. Oftentimes, due to time and cost constraints inferior equipment and maintenance agreements are put into place. This lead to having long-term effects on system efficiency and a changing effect on the comfort level.
The substandard maintenance agreement would cost you much. What the property owners and facility managers need to consider is to opt for qualified HVAC maintenance contractors for the preventive maintenance. The benefits you will have is the longer system life, energy efficiency, improved occupant comfort, and the enhanced uptime.
Here are the best practices you need to know:
Controlling your control system is an integral part of any HVAC system maintenance.
The control system of HVAC has a specific role and it can be a programmable thermostat or a complex robust automation system. These controls should be used to best optimize the overall HVAC system, thus can eliminate the energy waste and avoid comfort issues. Working with an efficiency expert can help you substantially decrease energy costs over the lifespan of your equipment.
Concurrent heating and cooling occur in many systems.
Another important factor that increases the operational costs is the simultaneous heating and cooling. When the required cooler air is delivered by the central system, the zone reheat coil must heat the air before it is delivered to space. This time, the heating and cooling system may be working against each other creating additional wear on the equipment.
Varied functioning of the chilled-water and hot water system cause the unit to work differently and lead to many discomforts. These factors will lead to under-heated or cooled situations causing the maintenance costs to rise.
Night setback and scheduling
When the HVAC in your building is properly controlled during unused times, a significant cost reduction can be achieved. Night, weekend and off-hour scheduling can be done easily and is simple to track and manage. The ultimate purpose is to shut off systems whenever they are not required and put to the system for minimal or occasional use. Many times, night-time operations can be the most costly, if roughly only a small percentage of staff are working and all heating, ventilating, and air conditioning equipment is running.
A few basic tactics to remember include
– Turn things off when not in use
– Close outdoor air dampers when the building is unoccupied
– Disable chillers and cooling equipment during unoccupied hours if possible
– Often test refrigerant charge to ensure optimum conditions
– Clean outdoor condenser by using a pressure sprayer.
– Keep filters clean for sufficient air flow and heat transfer.
Operation and maintenance:
Following the best practices and scheduling a regular maintenance of HVAC systems can alleviate the most commonly occurring issues you are facing. This way can reduce your high energy bills, increase the energy efficiency and the lifespan of the HVAC unit. Obtaining the right maintenance provider is crucial when it comes to implementing the periodic or preventive maintenance. In Kuwait, the best HVAC maintenance company you can depend on is Advanced Systems. Take action now to put practices into place for energy efficiencies and cost savings.
