Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need adequate space and airflow to heat properly.

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

Regular furnace maintenance is crucial to keep your system working well. A routinely serviced furnace may run more efficiently, which could lower your heating costs.

Maintenance often helps us discover issues before they start. This could help lower future repair costs and potentially prolong the life of your unit.

So how much clearance should your equipment really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or sealing off your furnace room, you should research manufacturer specifications and Racine ordinances for clearance rules.

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

You also need to ensure the space has enough airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This kind of furnace pulls combustion air from the surrounding area. If there’s insufficient air, unsafe gas fumes and deadly carbon monoxide could leak into your home.

If your furnace is placed in a small room with a gas water heater, you may need to add extra openings. This could include 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 modern, high-efficiency furnace with PVC piping. Your unit uses one pipe as an exhaust vent and the other to pull in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms are often also used for 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, place your litter box elsewhere. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could move the smelly odors throughout your home.

You should also frequently vacuum near your furnace to block dust from accumulating.
