When a technician is called to your house to check problems with HVAC, it’s a sure bet one of the first things he or she will examine is the furnace system. A dirty furnace not only restricts warm air flow but affects the temperature of the warm air flowing through. Furnace-based heat is reduced by blocked air flow. Plenty of problems are caused within a dirty furnace:
- Excessive dust buildup
- High energy consumption
One of the central components in a furnace is the A-coil. It got its name because of its shape. The A-coil contains hundreds of passages through which air flows. Naturally, if there are restrictions within these passages, air flow will suffer. Not surprisingly, these passages collect a large amount of dirt and dust over time. If the filter is not changed regularly and cleaning is neglected, the A-coil will eventually get clogged. The system will have to work harder to push the same amount of air. This leads to higher energy costs. In the worst case scenario, the coil becomes completely jammed, overheating the system, tripping the safety, and shutting the whole thing down. If this happens during a cold snap, the residents of the house will be wearing their parkas indoors.
The insides of HVAC systems are dark places. When warm air entering the area starts to condense, mould can grow. If there is a healthy passage of air, the likelihood of this happening is greatly reduced.
Clogs will eventually cause the furnace to break down. And you may be forced to replace the entire thing, a very costly option. HVAC systems should only be repaired and maintained by professionals. A-coils and other parts are not easily accessible to an amateur; licensed HVAC technicians use specialized tools, soft brushes, and compressed air to do their job.
