Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can shut down if it doesn’t have enough room. It also makes it challenging for our specialists to accomplish furnace repair.

Regular furnace maintenance is important to keep your equipment working smoothly. A regularly serviced furnace may heat more efficiently, which could decrease your utility costs.

Maintenance often helps us spot issues before they start. This could help reduce future repair bills and likely extend the life of your unit.

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 directions and Richardson ordinances for clearance guidelines.

As a general rule of thumb, your furnace should be 30 inches away from furnace room walls on all sides. This allows our service experts to conveniently repair it.

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

This model of furnace pulls combustion air from the nearby location. If there’s not enough air, unsafe gas fumes and deadly carbon monoxide could leak into your home.

If your furnace is positioned in a little room with a gas water heater, you may need to install more openings. This could consist of 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 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 function 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 elsewhere. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could move the stinky odors around your home.

You should also regularly clean near your furnace to prevent dust from building up.
