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

Your furnace can overheat if it doesn’t have enough room. It also makes it hard for our technicians to complete furnace repair.

Routine furnace maintenance is important to keep your unit operating smoothly. A regularly serviced furnace may heat more efficiently, which could decrease your energy bills.

Maintenance often helps us spot troubles before they become expensive. This could help reduce future repair costs and potentially extend the life of your system.

So how much room should your equipment really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or sealing off your furnace room, you should consult manufacturer directions and Houston statutes 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 professionals to easily work on it.

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

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

If your furnace is located in a tiny room with a gas water heater, you may need to install more openings. This could involve 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 modern, high-efficiency furnace with PVC piping. Your system uses one pipe as an exhaust vent and the other to draw in 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, 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 all over your home.

You should also frequently sweep by your furnace to prevent dust from developing.
