Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Routine furnace maintenance is essential to keep your unit operating smoothly. A regularly serviced furnace may work more efficiently, which could decrease your utility expenses.

Maintenance often helps us spot problems before they become expensive. This could help lessen future repair bills and likely prolong the life of your unit.

So how much clearance 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 specifications and Lawrence laws for clearance guidelines.

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

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

This kind of furnace needs combustion air from the nearby location. If there’s inadequate air, dangerous gas fumes and deadly carbon monoxide could flow back into your home.

If your furnace is positioned 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 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 add 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 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, put your litter box elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the unpleasant odors around your home.

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