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

Regular furnace maintenance is essential to keep your system running trouble-free. An annually serviced furnace may run more efficiently, which could reduce your heating bills.

So how much clearance should your equipment really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or sealing off your furnace room, you should consult manufacturer instructions and Tucker laws for clearance guidelines.

As a general rule of thumb, your system should be 30 inches away from furnace room walls on all sides. This lets our service technicians to comfortably repair it.

You also need to ensure the room has ample airflow and ventilation, especially if you have an aging furnace with a metal flue.

You don’t need to think about airflow and ventilation as much if you have a modern, high-efficiency furnace with PVC piping. Your system uses one pipe as an exhaust vent and the other to pull in air.

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 deteriorate your furnace’s heat exchanger. Plus, the furnace could circulate the unpleasant odors throughout your home.
