Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need sufficient space and airflow to heat correctly.

Your furnace can overheat if it doesn’t have enough room. It also makes it hard for our specialists to perform furnace repair.

Regular furnace maintenance is crucial to keep your unit operating well. A routinely serviced furnace may heat more efficiently, which could decrease your utility bills.

Maintenance often helps us notice issues before they begin. This could help lower future repair bills and potentially extend the life of your unit.

So how much area should your furnace really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or closing off your furnace room, you should research manufacturer specifications and Huffman statutes for clearance guidelines.

As a general recommendation, your furnace should be 30 inches away from furnace room walls on all sides. This allows our service experts to comfortably replace it.

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

This model of furnace pulls combustion air from the adjacent space. If there’s inadequate air, unsafe gas fumes and deadly carbon monoxide could back draft into your home.

If your furnace is placed in a little room with a gas water heater, you may need to add more openings. This could consist of 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 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, put your litter box somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could spread the stinky odors around your home.

You should also frequently vacuum near your furnace to stop dust from developing.
