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

Your furnace can overheat if it doesn’t have enough clearance. It also makes it challenging for our specialists to perform furnace repair.

Annual furnace maintenance is crucial to keep your system working trouble-free. A regularly serviced furnace may work more efficiently, which could lower your energy bills.

Maintenance often helps us spot troubles before they become expensive. This could help lower future repair expenses and likely prolong the life of your unit.

So how much clearance should your system really have?

How Much Space Will a Furnace Take Up?

If you’re updating your basement or enclosing your furnace room, you should take a look at manufacturer specifications and Oxford laws for clearance requirements.

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

You also need to make sure the area has ample airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This kind of furnace draws combustion air from the nearby space. If there’s inadequate air, hazardous gas fumes and poisonous carbon monoxide could back draft into your home.

If your furnace is located in a small room with a gas water heater, you may need to add 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 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 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, place your litter box in another room. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could circulate the stinky odors around your home.

You should also routinely sweep near your furnace to prevent dust from building up.
