Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can get too hot if it doesn’t have enough clearance. It also makes it difficult for our professionals to accomplish furnace repair.

Routine furnace maintenance is crucial to keep your equipment working well. An annually serviced furnace may heat more efficiently, which could decrease your heating bills.

Maintenance often helps us spot problems before they start. This could help lower future repair costs and possibly lengthen the life of your furnace.

So how much room should your system 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 Dallas statutes for clearance guidelines.

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

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

This type of furnace needs combustion air from the nearby area. If there’s inadequate air, hazardous gas fumes and deadly carbon monoxide could back draft into your home.

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

Keep Combustible Materials Away from Your Furnace

Although furnace rooms double 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, place your litter box in another room. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors around your home.

You should also regularly vacuum by your furnace to prevent dust from developing.
