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

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

Routine furnace maintenance is crucial to keep your system working well. An annually serviced furnace may heat more efficiently, which could lower your utility costs.

Maintenance often helps us notice problems before they start. This could help lessen future repair bills and likely extend the life of your furnace.

So how much room should your system really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or sealing off your furnace room, you should consult manufacturer instructions and Pacheco statutes for clearance requirements.

As a general rule of thumb, your heater should be 30 inches away from furnace room walls on all sides. This lets our service technicians to comfortably work on it.

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

This model of furnace draws combustion air from the surrounding area. If there’s not enough air, unsafe gas fumes and toxic carbon monoxide could flow back into your home.

If your furnace is placed in a little room with a gas water heater, you may need to install more 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 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 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, place your litter box somewhere else. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could move the smelly odors throughout your home.
