Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can get too hot if it doesn’t have enough clearance. It also makes it challenging for our specialists to accomplish furnace repair.

Regular furnace maintenance is important to keep your equipment running smoothly. A regularly serviced furnace may run more efficiently, which could lower your energy bills.

Maintenance often helps us notice problems before they begin. This could help lower future repair costs and potentially lengthen the life of your system.

So how much room should your system really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or closing off your furnace room, you should consult manufacturer directions and Wheeling ordinances for clearance guidelines.

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

You also need to ensure the area has ample airflow and ventilation, especially if you have an aging furnace with a metal flue.

This kind of furnace needs combustion air from the nearby area. If there’s not enough air, hazardous gas fumes and poisonous carbon monoxide could leak into your home.

If your furnace is placed in a little room with a gas water heater, you may need to put in 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 add 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 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, situate your litter box elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors throughout your home.

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