How Much Space Should I Leave Open Around My Furnace?

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

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

Annual furnace maintenance is crucial to keep your unit running trouble-free. An annually serviced furnace may heat more efficiently, which could lower your energy bills.

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

So how much room should your furnace really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or sealing off your furnace room, you should research manufacturer directions and Mount Pleasant laws for clearance guidelines.

As a general suggestion, your heater should be 30 inches away from furnace room walls on all sides. This permits our service experts to comfortably repair it.

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

This kind of furnace needs combustion air from the surrounding location. If there’s inadequate air, dangerous 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 put in extra openings. This could involve a fully louvered door or vents in the walls.

You don’t need to consider 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.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms double as laundry and storage space, you should keep yours free of things 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 somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could circulate the stinky odors around your home.

You should also frequently sweep around your furnace to block dust from developing.
