According to a recent study, of the people who own HVAC systems, only half of them actually take time to maintain them. This despite the fact that good maintenance of an HVAC system extends the life of the entire system, ensures that every component is functioning on high, leads to fresher air and most importantly, helps cut on energy costs to a great extent.
On estimate, regular maintenance of your HVAC system can cut energy costs by up to 50%. This, of course, depends on many factors such as the size of the system, the building being served by the system, the prevailing weather, and other minor environmental conditions such as the presence of dust in the air.
An HVAC system has more than 80 components. For you to save on energy costs there are a select number of components that should be attended to regularly. Let us now look at some of the reasons which might cause an HVAC system to run on more energy than it should. On top of this, we will also look at what should be done to correct the energy-consuming defects.
Leaks inside the compressor
Leaks inside the compressor reduce the amount of air flowing inside the unit at any given time. When fresh air cannot move beyond the condenser, the tubes underneath are blanketed because air is an insulator. Air also utilizes space meaning that some of the refrigerant vapor will be displaced. In such a scenario, the system will be exerting high pressure to move air past the condenser thus utilizing more energy.
As part of maintenance, you should test all the compressors for leaks. All leaking compressors should be replaced immediately.
Over time, microbes and iron accumulateon the inner surface of the tubes because of the moisture and the warm temperatures. In excess, these microbes and iron deposits interfere with energy transfer throughout the entire system. The heat transfer losses increase the energy consumed to a large extent.
To save on energy costs, all tubes must be cleaned regularly using water.
All filters need to be changed regularly. If filters can be cleaned you should do it regularly. This will surely save energy costs. Click here for furnace filters.
Clogged nozzles, line strainers, and valves
Over time, some valves will close partially due to sediment accumulation in the condenser tubes. Air in the piping system will also cause nozzles in the cooling tower to be blocked. This strains the entire system meaning that more energy will be consumed.
The flow in the condenser should be monitored at least once a year. All sediment should also be removed in the condenser tubes. The air in the piping system will be automatically released when you open up the piping system on one side. Important to mention, the condenser should not be covered to prevent the sediment from falling inside because this will actually lead to more energy consumption.
Inadequate refrigerant charge
An inadequate refrigerant charge will cause the chillers to utilize more energy in order to cool up the building. To save on energy costs, there should be optimal refrigerant charge in the HVAC system. Refrigerant levels should be maintained at the level recommended by your HVAC system manufacturer.
