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

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

Regular furnace maintenance is important to keep your unit operating trouble-free. An annually serviced furnace may work more efficiently, which could reduce your heating bills.

Maintenance often helps us notice problems before they start. This could help reduce future repair costs and potentially extend the life of your unit.

So how much clearance should your equipment really have?

How Much Space Will a Furnace Take Up?

If you’re remodeling your basement or enclosing your furnace room, you should research manufacturer specifications and Phoenix ordinances for clearance guidelines.

As a general suggestion, your system should be 30 inches away from furnace room walls on all sides. This lets our service experts to comfortably work on 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 kind of furnace needs combustion air from the nearby location. If there’s inadequate air, hazardous gas fumes and toxic carbon monoxide could leak into your home.

If your furnace is placed in a small 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 newer, high-efficiency furnace with PVC piping. Your system uses one pipe as an exhaust vent and the other to add air.

Keep Hazardous Items Away from Your Furnace

Although furnace rooms function as laundry and storage space, you should keep yours free of things 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 create wear on your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors all over your home.

You should also regularly vacuum around your furnace to block dust from building up.
