Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Regular furnace maintenance is essential to keep your unit operating trouble-free. A routinely serviced furnace may heat more efficiently, which could reduce your utility costs.

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

So how much area should your equipment really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or enclosing your furnace room, you should take a look at manufacturer directions 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 comfortably repair it.

You also need to check the area 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 area. If there’s insufficient air, unsafe gas fumes and poisonous 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 consider airflow and ventilation as much if you have a up-to-date, high-efficiency furnace with PVC piping. Your system uses one pipe as an exhaust vent and the other to draw 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, put your litter box elsewhere. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could move the stinky odors all over your home.

You should also regularly clean around your furnace to block dust from developing.
