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

Your furnace can overheat if it doesn’t have enough space. It also makes it hard for our professionals to perform furnace repair.

Annual furnace maintenance is crucial to keep your unit running well. A routinely serviced furnace may work more efficiently, which could decrease your heating costs.

Maintenance often helps us discover troubles before they begin. This could help lessen future repair expenses and potentially extend the life of your furnace.

So how much area should your system really have?

How Much Space Will a Furnace Take Up?

If you’re updating your basement or closing off your furnace room, you should take a look at manufacturer specifications and Des Moines 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 conveniently replace it.

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

This model of furnace needs combustion air from the surrounding space. If there’s insufficient air, unsafe gas fumes and deadly carbon monoxide could leak into your home.

If your furnace is located in a tiny room with a gas water heater, you may need to add more openings. This could include 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 up-to-date, high-efficiency furnace with PVC piping. Your furnace uses one pipe as an exhaust vent and the other to draw in 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, situate your litter box elsewhere. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could move the stinky odors all over your home.

You should also routinely vacuum near your furnace to stop dust from accumulating.
