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

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

Regular furnace maintenance is essential to keep your unit operating smoothly. A routinely serviced furnace may work more efficiently, which could decrease your heating expenses.

If you’re updating your basement or sealing off your furnace room, you should research manufacturer instructions and Wharton ordinances for clearance requirements.

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

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

You don’t need to assess 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 function 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 somewhere else. Cat urine contains ammonia, which could create wear on your furnace’s heat exchanger. Plus, the furnace could spread the unpleasant odors around your home.

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