Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need adequate space and airflow to work 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 important to keep your equipment operating smoothly. A regularly serviced furnace may run more efficiently, which could lower your utility bills.

Maintenance often helps us discover issues before they start. This could help lower future repair bills and potentially lengthen the life of your unit.

So how much area should your system really have?

How Much Space Does My Furnace Need?

If you’re remodeling your basement or closing off your furnace room, you should take a look at manufacturer instructions and Tuscaloosa statutes for clearance requirements.

As a general rule of thumb, your heater 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You also need to check the space has enough airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This model of furnace needs combustion air from the adjacent space. If there’s inadequate air, hazardous gas fumes and deadly carbon monoxide could leak into your home.

If your furnace is placed in a tiny room with a gas water heater, you may need to add 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 unit uses one pipe as an exhaust vent and the other to add air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms function as laundry and storage space, you should keep yours free of clutter 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 spread the stinky odors around your home.

You should also regularly vacuum by your furnace to stop dust from accumulating.
