Our society makes use of furnaces for several purposes including a method for smelting metals and baking ceramics, but the most common usage for furnace technologies is the heating and cooling of our buildings and homes. Heating furnaces, sometimes known as forced air or central heating systems, come in both gas burning varieties and electric versions. The systems are reasonably simple in concept, although some varieties can be quite complex in actual design and may require specific Furnace Repair when they break. This is especially true for high efficiency furnace systems that rate in the ninety percent and higher efficiency class.
Like any appliance, a furnace can wear out and break down. Gas based furnaces have several points that can fail including the ignition system, the fuel delivery and the exhaust although some high efficiency versions don’t require an exhaust because of their fuel economy and design. Electric models are a bit simpler with an electric coil for generating heat. The coil works by applying an electrical current to the coil and creating an electrical resistance, the resistance then generates the heat. This effect is similar to that used in the electric range and stove burners.
The majority of central heating units are a part of a combined HVAC (Heating, Ventilation and Air Conditioning) system and takes advantage of part of that system for distributing the conditioned air. For example, both systems use a common blower that must function almost all year round. While this blower system uses industrial grade motor and squirrel cage, it can still malfunction. You can easily avoid many of these problems by purchasing a maintenance plan from your favorite contractor.
Along with Furnace Repair, maintenance plans are the best way to keep your comfort appliance running for many years. These maintenance programs cover both cleaning and servicing of the system, but specifics will depend on the contractor. One of the most important components that should be cleaned every few years is the evaporator coil in the air exchange. This coil sweats and picks up any loose dust that passes through the filter system. This caked on dust can block the airflow and reduce the efficiency of your HVAC.
