Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need enough space and airflow to heat right.

Your furnace can overheat if it doesn’t have enough room. It also makes it difficult for our technicians to perform furnace repair.

Regular furnace maintenance is important to keep your system running smoothly. An annually serviced furnace may work more efficiently, which could decrease your utility expenses.

Maintenance often helps us spot troubles before they begin. This could help lessen future repair expenses and potentially extend the life of your system.

So how much room should your equipment really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or enclosing your furnace room, you should consult manufacturer specifications and Middle Georgia statutes for clearance requirements.

As a general suggestion, your system should be 30 inches away from furnace room walls on all sides. This permits our service professionals to easily work on it.

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

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

If your furnace is placed in a tiny room with a gas water heater, you may need to put in supplemental 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 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 function 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, place your litter box somewhere else. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could move the unpleasant odors around your home.

You should also frequently vacuum around your furnace to stop dust from building up.
