Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

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

Regular furnace maintenance is crucial to keep your unit running smoothly. A regularly serviced furnace may run more efficiently, which could decrease your energy bills.

Maintenance often helps us notice troubles before they start. This could help lower future repair costs and potentially extend the life of your unit.

So how much room should your system really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or sealing off your furnace room, you should take a look at manufacturer instructions and Edinburg ordinances for clearance rules.

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

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

This kind of furnace draws combustion air from the nearby space. If there’s inadequate air, hazardous gas fumes and toxic carbon monoxide could leak into your home.

If your furnace is placed in a little room with a gas water heater, you may need to put in supplemental 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 newer, high-efficiency furnace with PVC piping. Your furnace uses one pipe as an exhaust vent and the other to draw in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms are often also used for laundry and storage space, you should keep yours free of items 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 create wear on your furnace’s heat exchanger. Plus, the furnace could move the unpleasant odors throughout your home.

You should also routinely clean around your furnace to stop dust from accumulating.
