HVAC systems are usually the most expensive appliances found in homes. These units keep homes comfortable, regardless of the conditions outside, by providing heating and cooling. When they are properly maintained, the systems can provide years of efficient and dependable comfort.
Although air conditioning systems all work in pretty much the same way to cool the living space, there are several options available to keep the home warm during the winter. Whether units use a furnace or heat pump, the homeowner’s portion of maintenance will remain basically the same. However, when it is time for service by an HVAC technician, there are significant differences in service provided.
All forced air systems use a filter. This filter is usually easily accessible and should be checked at least once per month and replaced when dirty. At the very least filters should be changed once every three months. In addition to improving air quality inside the home, the filter protects the coils inside the unit from dirt and dust.
Systems that provide air conditioning also have a parts located outside the home. These units should be rinsed to remove dust, pollen and dirt, using a garden hose. In addition, landscaping and other obstructions should be trimmed to provide clearance for unobstructed air flow.
Regardless of the source of heat, systems need annual maintenance from a certified technician. The tech will check and balance coolant levels in air conditioning systems and heat pumps. If the device uses a burner to produce heat, it will be cleaned and the flame adjusted for maximum efficiency. The unit is also checked to ensure it can continue to operate safely.
Maintenance of a heating and cooling system is needed to ensure it remains efficient and safe. Systems that are not serviced will lose as much as 10% efficiency each year. Most owners find the cost of a service call to be recovered in lower costs for utilities.
