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

Your furnace can shut down if it doesn’t have enough space. It also makes it hard for our technicians to accomplish furnace repair.

Annual furnace maintenance is important to keep your unit operating well. An annually serviced furnace may run more efficiently, which could lower your energy bills.

Maintenance often helps us notice problems before they start. This could help lower future repair costs and likely prolong the life of your system.

So how much clearance should your furnace really have?

How Much Space Will a Furnace Take Up?

If you’re remodeling your basement or sealing off your furnace room, you should research manufacturer specifications and Cape Coral laws for clearance requirements.

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

You also need to check the space has plentiful airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This type of furnace needs combustion air from the nearby space. If there’s insufficient air, hazardous gas fumes and toxic carbon monoxide could flow back into your home.

If your furnace is located in a little room with a gas water heater, you may need to put in supplemental 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 add 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 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 in another room. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could move the stinky odors throughout your home.

You should also routinely vacuum around your furnace to block dust from accumulating.
