Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need sufficient space and airflow to run properly.

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

Regular furnace maintenance is crucial to keep your unit operating well. A routinely serviced furnace may work more efficiently, which could reduce your heating costs.

Maintenance often helps us discover problems before they begin. This could help lower future repair costs and likely extend the life of your furnace.

So how much clearance 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 research manufacturer instructions and Tomball statutes for clearance guidelines.

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

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

This type of furnace draws combustion air from the surrounding location. If there’s inadequate air, unsafe gas fumes and toxic carbon monoxide could leak into your home.

If your furnace is positioned in a tiny 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 assess airflow and ventilation as much if you have a modern, high-efficiency furnace with PVC piping. Your unit 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, put your litter box in another room. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors all over your home.

You should also regularly sweep around your furnace to stop dust from developing.
