Natural gas furnaces need adequate space and airflow to run right.

Your furnace can get too hot if it doesn’t have enough room. It also makes it difficult for our technicians to complete furnace repair.

Annual furnace maintenance is important to keep your unit working smoothly. A routinely serviced furnace may heat more efficiently, which could reduce your heating bills.

Maintenance often helps us notice troubles before they start. This could help lessen future repair costs and possibly prolong the life of your furnace.

So how much clearance should your furnace really have?

How Much Space Will a Furnace Take Up?

If you’re finishing your basement or closing off your furnace room, you should consult manufacturer specifications and Santa Clarita laws for clearance guidelines.

As a general recommendation, your furnace should be 30 inches away from furnace room walls on all sides. This allows our service experts to easily replace it.

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

This type of furnace draws combustion air from the adjacent space. If there’s inadequate air, unsafe 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 install extra openings. This could involve a fully louvered door or vents in the walls.

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

Keep Flammable Items 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 somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could move the smelly odors throughout your home.

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