Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can get too hot if it doesn’t have enough room. It also makes it challenging for our specialists to accomplish furnace repair.

Regular furnace maintenance is important to keep your equipment operating trouble-free. An annually serviced furnace may run more efficiently, which could lower your heating expenses.

Maintenance often helps us spot problems before they become expensive. This could help lower future repair bills and likely prolong the life of your unit.

So how much clearance should your furnace really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or sealing off your furnace room, you should consult manufacturer directions and Mechanicsville ordinances for clearance rules.

As a general recommendation, your system 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 area has enough airflow and ventilation, especially if you have an aging furnace with a metal flue.

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

If your furnace is located in a tiny room with a gas water heater, you may need to install supplemental openings. This could include 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 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, place your litter box somewhere else. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could circulate the smelly odors around your home.

You should also routinely vacuum around your furnace to stop dust from building up.
