Winter is just around the corner, and it is time to think about certain necessities such as heating the home. There are various devices to handle this task, but one of the most common is the central furnace. A furnace can be either a gas-burning appliance or one that makes use of electrical resistance. The differences in these heating methods can change the type of Furnace Repair required when the appliance fails. For instance, electric units use a coil that heats up when electricity flows through it. This coil can fail after extended use and prevent the system from heating the building. Another way that the unit may fail is a broken sensing switch that prevents the blower from operating.
Gas-based furnaces tend to be more complex because the appliance requires a method of regulating the flow of fuel. Another area where gas burning systems may require Furnace Repair is the exhaust. Burning fuels tend to leave various deposits in the exhaust system that may block the release of waste gases. This slows the flow of fresh air into the combustion chamber and can prevent the unit from burning properly. In fact, the exhaust should be cleaned as part of the appliance’s routine maintenance, but some contractors overlook this issue or skip it completely.
This may not pose a problem at first, but tar and other gunk can collect on the flue and prevent it from opening or closing as required. One of the most important repairs a furnace can have is internal cleaning. This is especially true when the unit is part of an HVAC (heating, ventilation, and air conditioning) system because the heating chamber can fill with lint and dust that may be flammable. Cleaning the system should be done in the late fall or early winter before the appliance is used. This schedule reduces the chance of a flash fire and some very costly damages.
Other annual maintenance procedures that may prove helpful include cleaning the blower and air handler. These areas are often overlooked because they can be difficult to access. However, they are the primary areas where the air flows and will affect indoor air quality.
