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

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

Regular furnace maintenance is essential to keep your unit working well. A routinely serviced furnace may run more efficiently, which could decrease your energy expenses.

So how much room should your equipment really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or sealing off your furnace room, you should consult manufacturer directions and Lexington laws for clearance guidelines.

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

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

This kind of furnace needs combustion air from the surrounding area. If there’s not enough air, dangerous gas fumes and poisonous 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 extra openings. This could consist of a fully louvered door or vents in the walls.

You don’t need to think about 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 double as laundry and storage space, you should keep yours free of items 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, situate your litter box somewhere else. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors all over your home.

You should also frequently vacuum near your furnace to prevent dust from building up.
