How to Deal with Three Common Furnace Problems

Often, Fairfax, VA homeowners do not think too much about their furnaces until they start to notice problems with the system in the wintertime. The older your furnace is, the more likely it is to malfunction or need repair. Some problems are minor, and you can fix them yourself or others require a Fairfax HVAC professional to quickly and completely remedy the situation. More serious problems may require you to upgrade your furnace by replacing it with a new unit. Here are the solutions to three of the most common furnace problems in Fairfax.

Blowing Dust

Dust and other forms of dirt can build up inside your ducts and get blown out when your furnace switches on. If your system’s air filter is dirty, it may not be catching all the particles it should. Sometimes, you can solve this problem by simply wiping the vents clean and changing the air filter. Using an electrostatic filter can help capture more microscopic particles, but in extreme cases, you may need to have your air ducts cleaned to remove years of grime buildup.

Noisy Operation

Though no furnace can operate completely silent, you should not hear excessive banging or clanging sounds when the furnace is running in your Fairfax home. Even a persistent low buzzing sound can be a symptom of serious problems with your furnace. Schedule a tune-up with a Fairfax HVAC professional to find out what is causing the problem. Your furnace may be making noise because the blower motor belt is damaged, or because one of the fan blades is nicked. If the furnace is very old and if the metal components have excessive rust or corrosion, it might be time to replace your furnace with a newer, high-efficiency model.

Strange Smells

If you notice a musty smell every time your furnace comes on, you should have your ducts inspected to determine if there is any mold growing inside them. Burning smells coming from your vents can indicate serious problems with dirt buildup inside your furnace, or a problem with the ducts and fans that should vent furnace exhaust outside your home. However, of the most deadly byproducts of burning gas or heating oil, carbon monoxide, is odorless and colorless, so you should keep an alarm inside your home to detect the presence of this toxic gas. If your furnace is producing carbon monoxide fumes, you definitely need to replace it with a newer model.
