Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Regular furnace maintenance is important to keep your unit running smoothly. An annually serviced furnace may heat more efficiently, which could lower your energy bills.

Maintenance often helps us notice troubles before they begin. This could help reduce future repair expenses and potentially prolong the life of your system.

So how much area should your furnace really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or sealing off your furnace room, you should take a look at manufacturer directions and Bossier City ordinances for clearance requirements.

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

You also need to check the area has enough airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This type of furnace pulls combustion air from the surrounding location. If there’s inadequate air, hazardous gas fumes and poisonous carbon monoxide could back draft into your home.

If your furnace is placed in a tiny room with a gas water heater, you may need to install 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 up-to-date, high-efficiency furnace with PVC piping. Your furnace uses one pipe as an exhaust vent and the other to pull in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms function as laundry and storage space, you should keep yours free of items 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 somewhere else. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors throughout your home.

You should also frequently sweep by your furnace to prevent dust from accumulating.
