How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need adequate space and airflow to work correctly.

Your furnace can get too hot if it doesn’t have enough space. It also makes it difficult for our specialists to perform furnace repair.

Annual furnace maintenance is crucial to keep your system running smoothly. A regularly serviced furnace may heat more efficiently, which could reduce your utility expenses.

Maintenance often helps us discover issues before they begin. This could help reduce future repair expenses and possibly lengthen the life of your unit.

So how much clearance should your system really have?

How Much Space Does My Furnace Need?

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

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

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

This kind of furnace pulls combustion air from the nearby area. If there’s not enough air, hazardous gas fumes and poisonous carbon monoxide could back draft into your home.

If your furnace is positioned in a tiny room with a gas water heater, you may need to install more openings. This could consist of 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 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 are often also used for 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, put your litter box somewhere else. Cat urine contains ammonia, which could deteriorate your furnace’s heat exchanger. Plus, the furnace could move the stinky odors all over your home.

You should also routinely clean near your furnace to prevent dust from developing.
