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.

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.

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.

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.
