Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need enough space and airflow to work right.

Your furnace can get too hot if it doesn’t have enough space. It also makes it challenging for our technicians to complete furnace repair.

Routine furnace maintenance is important to keep your unit operating smoothly. A routinely serviced furnace may run more efficiently, which could lower your utility bills.

Maintenance often helps us spot problems before they start. This could help reduce future repair expenses and likely lengthen the life of your unit.

So how much clearance should your equipment really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or closing off your furnace room, you should take a look at manufacturer specifications and Ronkonkoma laws for clearance rules.

As a general rule of thumb, your system should be 30 inches away from furnace room walls on all sides. This permits our service professionals to comfortably replace it.

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

This model of furnace draws combustion air from the adjacent space. If there’s inadequate air, hazardous gas fumes and poisonous carbon monoxide could leak into your home.

If your furnace is positioned in a small room with a gas water heater, you may need to put in supplemental openings. This could consist of 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 unit uses one pipe as an exhaust vent and the other to add 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, place your litter box elsewhere. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could spread the stinky odors around your home.

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