Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

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

Your furnace can overheat if it doesn’t have enough space. It also makes it challenging for our specialists to complete furnace repair.

Annual furnace maintenance is essential to keep your system operating trouble-free. A regularly serviced furnace may run more efficiently, which could lower your energy costs.

Maintenance often helps us discover issues before they become expensive. This could help lessen future repair costs and likely prolong the life of your unit.

So how much clearance should your equipment really have?

How Much Space Does My Furnace Need?

If you’re updating your basement or closing off your furnace room, you should research manufacturer specifications and Manassas Park ordinances for clearance guidelines.

As a general rule of thumb, your furnace should be 30 inches away from furnace room walls on all sides. This allows our service experts to easily replace it.

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

This kind of furnace pulls combustion air from the surrounding location. If there’s not enough air, dangerous gas fumes and toxic carbon monoxide could back draft 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 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 newer, high-efficiency furnace with PVC piping. Your unit uses one pipe as an exhaust vent and the other to pull in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms double as 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, put your litter box in another room. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could circulate the unpleasant odors all over your home.

You should also routinely clean around your furnace to block dust from building up.
