How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need enough space and airflow to work properly.

Your furnace can overheat if it doesn’t have enough room. It also makes it difficult for our professionals to complete furnace repair.

Regular furnace maintenance is essential to keep your equipment running well. A regularly serviced furnace may heat more efficiently, which could lower your utility expenses.

Maintenance often helps us notice problems before they start. This could help lessen future repair bills and likely lengthen the life of your unit.

So how much area should your system really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or enclosing your furnace room, you should take a look at manufacturer directions and Greater Richmond statutes for clearance guidelines.

As a general rule of thumb, your furnace should be 30 inches away from furnace room walls on all sides. This lets our service technicians to easily work on it.

You also need to check the area has plentiful airflow and ventilation, especially if you have an aging furnace with a metal flue.

This kind of furnace needs combustion air from the nearby space. If there’s inadequate air, unsafe gas fumes and deadly carbon monoxide could flow back into your home.

If your furnace is positioned in a little room with a gas water heater, you may need to put in extra openings. This could involve a fully louvered door or vents in the walls.

You don’t need to assess airflow and ventilation as much if you have a newer, high-efficiency furnace with PVC piping. Your furnace uses one pipe as an exhaust vent and the other to pull in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms double as laundry and storage space, you should keep yours free of clutter that could be fire hazards.

This includes:

  • Clotheslines
  • Cleaning or laundry products
  • Gasoline, paint or paint thinner
  • Rags and papers
  • Wood scraps and sawdust
  • Used filters

If you have a cat, place your litter box elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the unpleasant odors all over your home.

You should also routinely vacuum around your furnace to stop dust from accumulating.
