If you are a regular to our blog, you’ll know that we recommend an annual check up of your furnace.
Regular maintenance on your furnace can help prevent some common repairs, like the following three.
The fan in your heating system has several components that can fall into disrepair when left unattended and cleaned. Problems commonly detected and attended to with regular maintenance include:
- friction created by dry ball bearings in the fan shaft
- loose or bent fan blades
- loose motor mounts
- worn fan belts
- motor issues and electrical issues, including frayed wiring
During maintenance, the fan and surrounding components will be properly inspected, cleaned, and optimized.
Components in your furnace can become dirty. When the burner is covered in a layer of dust and dirt, problems can develop, such as uneven heating, an inability for all the burners to light, and excessive wear and tear.
During routine maintenance, the burner is inspected and cleaned, so that it can function optimally.
Many contemporary furnaces light via electronic ignition. There are two types of electronic ignition: intermittent and hot surface. With both types, the igniters can become dirty.
The fuel nozzle in the intermittent pilot can become clogged, which can block the gas from flowing. With the hot surface igniter, dirt on the outside of the igniter can act as insulation, and the igniter won’t become hot enough to light the gas jet.
Part of routine maintenance involves cleaning these components, which helps prevent issues caused by dirt and grime.
