Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need enough space and airflow to run correctly.

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

Routine furnace maintenance is important to keep your equipment working trouble-free. An annually serviced furnace may work more efficiently, which could reduce your energy bills.

Maintenance often helps us spot issues before they start. This could help lower future repair costs and likely extend the life of your furnace.

So how much area should your furnace really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or closing off your furnace room, you should research manufacturer directions and Rocky Mount statutes for clearance requirements.

As a general recommendation, your furnace should be 30 inches away from furnace room walls on all sides. This permits our service technicians to easily repair it.

You also need to ensure the room has ample airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This kind of furnace draws combustion air from the adjacent space. If there’s inadequate air, hazardous gas fumes and poisonous carbon monoxide could back draft into your home.

If your furnace is placed in a tiny room with a gas water heater, you may need to put in extra openings. This could include 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 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 deteriorate your furnace’s heat exchanger. Plus, the furnace could move the unpleasant odors all over your home.

You should also routinely clean near your furnace to block dust from accumulating.
