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 specialists to complete furnace repair.

Annual furnace maintenance is important to keep your unit running well. An annually serviced furnace may run more efficiently, which could lower your heating expenses.

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 consult manufacturer directions and Franklin Lakes statutes for clearance rules.

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

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

This model of furnace needs combustion air from the adjacent location. If there’s inadequate air, unsafe gas fumes and poisonous carbon monoxide could leak into your home.

If your furnace is located in a tiny room with a gas water heater, you may need to install extra openings. This could involve 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 newer, 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 double as 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, situate your litter box somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could circulate the unpleasant odors around your home.

You should also regularly vacuum near your furnace to prevent dust from building up.
