Your furnace can shut down if it doesn’t have enough clearance. It also makes it difficult for our professionals to complete furnace repair.

Routine furnace maintenance is important to keep your unit running trouble-free. A routinely serviced furnace may work more efficiently, which could reduce your energy costs.

Maintenance often helps us discover troubles before they begin. This could help lessen future repair costs and possibly extend the life of your system.

So how much area should your system 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 specifications and Frederick statutes 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 repair it.

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

This kind of furnace draws combustion air from the surrounding space. If there’s not enough air, hazardous gas fumes and poisonous carbon monoxide could flow back into your home.

If your furnace is placed in a small room with a gas water heater, you may need to add supplemental openings. This could consist of 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 modern, high-efficiency furnace with PVC piping. Your unit uses one pipe as an exhaust vent and the other to draw in air.

Keep Hazardous Items A Safe Distance 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 in another room. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could circulate the unpleasant odors around your home.

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