Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need enough space and airflow to run properly.

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

Annual furnace maintenance is essential to keep your unit working trouble-free. A regularly serviced furnace may work more efficiently, which could lower your heating bills.

Maintenance often helps us spot problems before they start. This could help lower future repair costs and possibly lengthen the life of your furnace.

So how much room should your equipment really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or closing off your furnace room, you should research manufacturer instructions and Dallas laws for clearance guidelines.

As a general recommendation, your system should be 30 inches away from furnace room walls on all sides. This allows our service experts to easily replace it.

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

This type of furnace needs combustion air from the adjacent area. If there’s insufficient air, unsafe gas fumes and deadly carbon monoxide could back draft into your home.

If your furnace is positioned in a small room with a gas water heater, you may need to add extra openings. This could include a fully louvered door or vents in the walls.

You don’t need to assess 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 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, place your litter box in another room. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could move the stinky odors throughout your home.

You should also frequently vacuum near your furnace to prevent dust from developing.
