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 overheat if it doesn’t have enough room. It also makes it hard for our specialists to perform furnace repair.

Annual furnace maintenance is important to keep your system working smoothly. An annually serviced furnace may run more efficiently, which could decrease your energy costs.

Maintenance often helps us discover problems before they become expensive. This could help reduce future repair costs and possibly extend the life of your furnace.

So how much area should your furnace really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or enclosing your furnace room, you should consult manufacturer specifications and Kingsville laws 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 professionals to comfortably replace it.

You also need to make sure the area has enough airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This type of furnace draws combustion air from the nearby location. If there’s insufficient air, unsafe gas fumes and poisonous carbon monoxide could flow back into your home.

If your furnace is placed in a little room with a gas water heater, you may need to add supplemental openings. This could involve a fully louvered door or vents in the walls.

You don’t need to think about airflow and ventilation as much if you have a newer, 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 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, situate your litter box elsewhere. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could move the unpleasant odors around your home.

You should also routinely clean around your furnace to prevent dust from accumulating.
