So how much room should your furnace really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or enclosing your furnace room, you should consult manufacturer instructions and Phoenix ordinances for clearance rules.

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

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

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

If your furnace is placed in a little room with a gas water heater, you may need to install supplemental openings. This could involve a fully louvered door or vents in the walls.

You don’t need to consider airflow and ventilation as much if you have a up-to-date, high-efficiency furnace with PVC piping. Your system uses one pipe as an exhaust vent and the other to pull in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms function 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, situate your litter box in another room. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could spread the stinky odors around your home.
