Regular furnace maintenance is crucial to keep your unit operating smoothly. A regularly serviced furnace may work more efficiently, which could decrease your energy bills.

So how much room should your system really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or sealing off your furnace room, you should take a look at manufacturer instructions and Dayton laws for clearance rules.

As a general suggestion, your system should be 30 inches away from furnace room walls on all sides. This lets our service experts to easily work on it.

You also need to ensure the room has plentiful airflow and ventilation, especially if you have an older furnace with a metal flue.

This kind of furnace draws combustion air from the nearby area. If there’s insufficient air, unsafe gas fumes and toxic carbon monoxide could flow back into your home.

If your furnace is positioned in a tiny room with a gas water heater, you may need to add more 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 modern, high-efficiency furnace with PVC piping. Your furnace uses one pipe as an exhaust vent and the other to add air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms function as laundry and storage space, you should keep yours free of things 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, put your litter box elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors around your home.

You should also regularly vacuum around your furnace to prevent dust from building up.
