With gas appliances come great responsibility. No, it’s not superhero-level pressure, but maintaining gas appliances properly is critical to safety, efficiency, and longevity. 

Whether you’re cooking dinner, heating your water, or getting cozy by the fireplace, these maintenance tips can help protect your home and wallet.

General Safety First

Before you start any maintenance:

  • Turn off the gas supply.
  • Allow appliances to cool completely.
  • Always relight your pilot light safely when you’re finished.

Gas Stove & Oven Maintenance

Unlike electric models, gas stoves need a bit of specialized care. Regular cleaning can prevent clogs, uneven flames, and safety issues.

How to Clean Gas Stove Grates

Grates create space between the burner and your cookware. To keep them in good shape:

  • Remove them by simply lifting off the stove.
  • Soak and scrub monthly using an abrasive powder if needed.
  • Dry thoroughly and return to their proper spots.

How to Clean Gas Stove Burners

Uneven flames? It might be time to clean the burner channels:

  1. Turn off the gas (especially for models with a standing pilot light).
  2. Remove burner caps and bases (note which parts go where!).
  3. Scrub gently with a soft pad and mild cleaner (no dishwashers unless the manual says it's okay).
  4. Clean burner channels with a needle or fine wire, not a toothpick.
  5. Dry fully, reassemble carefully, and run a test.

If burners won’t light properly, double-check alignment and part placement.

Gas Water Heater & Boiler Maintenance

Your gas water heater should be serviced every six months. Follow your user manual or check out our maintenance video for a full walkthrough.

Boiler Maintenance Tips:

  • Drain and flush the system twice a year.
  • Descale lime buildup as needed.
  • Monitor water levels and inspect for leaks.
  • Lubricate moving parts every 6 months.

Important: If you spot puddles or leaks, call a professional right away. High pressure inside the boiler can be dangerous.

Gas Furnace Maintenance

Keeping your gas furnace in top shape not only prevents issues, it can lower your energy bills.

Here’s how:

  • Replace filters regularly.
  • Clean ductwork, vents, and registers.
  • Check for worn parts and connections.

A little routine maintenance can help your furnace work more efficiently and extend its life. Check out our step-by-step furnace guide for more.

Gas Fireplace Maintenance

Gas fireplaces may be clean-burning, but they’re not mess-free. They still require monthly cleaning and an annual inspection—ideally in late summer or early fall.

Here’s What To Do:

  1. Turn off the gas and let everything cool.
  2. Lay down a drop cloth and carefully remove components (logs, glass or mesh screens).
  3. Take photos during disassembly to make reassembly easier.
  4. Vacuum dust with brush attachments (cover the nozzle with cheesecloth to protect decorative rocks).
  5. Use a soft brush or cloth to clean vented logs (never use water or cleaners).
  6. Clean glass with a fireplace-safe solution.
  7. Vacuum both sides of metal mesh or screens.
  8. Clear any debris from outside vents.

Vent-free gas logs must only be removed by a licensed professional.

If you see any cracks, corrosion, or broken parts, replace them before your next use.
