There are variety of methods for heating a home, but the most comforting option, next to the fireplace or wood stove, is the forced air heating unit. This may be a standalone furnace which was common in many older homes or as part of an HVAC (Heating, Ventilation and Air Conditioning) system. Either way, the furnace may use natural gas for heating the air or electrical resistance. The former is often preferred because it produces warm air a little sooner and tends to be more efficient in function. One downside to using a forced air or central heating system is the occasional need for Furnace Repair in Portland.
Furnace repair can involve a number of tasks, and it often depends on the type of appliance being used. For instance, if the forced air system is part of an HVAC, then there is the chance that the blower may fail a little sooner or that the AC coil in the air exchanger becomes clogged. These may seem like small problems, but it still requires an expert in Furnace Repair in Portland to handle these jobs. Consider the blocked coil. This usually happens because filter systems on most furnaces are inadequate when it comes to eliminating smaller dust particles. This dust then mixes with any moisture on the evaporator coil. Over time, this gunk can block portions of the coil, which means that the heat may not make it past the air exchanger. The solution is to remove the coil and clean it in an acid bath.
It can be difficult to diagnose a problem with the furnace without looking at the appliance. One reason for this is the micro-switches and sensors required for cycling the apparatus. For instance, the air exchanger needs to know when a certain temperature is reached before cycling on the blower. Likewise, it needs to know the air exchanger is cool enough before shutting the blower off. This is the primary reason that a heating system still functions after the thermostat has been changed. Why is this required? Primarily to avoid excessive moisture buildup inside the system as the metal cools. The end result is a longer lasting appliance because the chance of corrosion has been reduced. Visit for further details.
