Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Regular furnace maintenance is crucial to keep your equipment working well. A routinely serviced furnace may run more efficiently, which could reduce your heating bills.

Maintenance often helps us discover troubles before they begin. This could help lower future repair costs and possibly lengthen the life of your unit.

So how much room should your system really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or enclosing your furnace room, you should take a look at manufacturer specifications and Libertyville ordinances for clearance requirements.

As a general rule of thumb, your furnace should be 30 inches away from furnace room walls on all sides. This allows our service professionals to conveniently repair it.

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

This model of furnace pulls combustion air from the surrounding location. If there’s insufficient 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 consider airflow and ventilation as much if you have a newer, high-efficiency furnace with PVC piping. Your system uses one pipe as an exhaust vent and the other to draw 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, put your litter box somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors around your home.

You should also frequently clean around your furnace to block dust from accumulating.
