Gas Furnace Issues: What's Up, Salem?

Winter’s here in Salem, New Hampshire, and you know the drill: cozy sweaters, hot cocoa, and good ol’ reliable gas furnaces to keep us toasty. But what if that trusty furnace decides to be a little moody?

Common Furnace Problems

Gas furnaces are usually reliable, but sometimes they act up. At Cornerstone Services, we understand the frustration. Here’s the lowdown on common gas furnace problems Salem folks might face. Remember, let the pros handle the fixes.

1. Furnace Won’t Start

You crank up the thermostat expecting that cozy hum, but nothing happens. Could be:

  • Thermostat acting up – make sure it’s set to “heat” and the temperature is higher than your room’s.
  • Circuit breaker playing tricks – check if it tripped.
  • Pilot light out – if the pilot light is out, professional help is needed.

2. Not Enough Heat

Your furnace runs, but the warmth is a letdown. Possible causes:

  • Dirty air filters – swap or clean them regularly to maintain airflow.
  • Vent blockage – open vents and clear any obstructions.

3. Nonstop Cycling

If your furnace is cycling on and off repeatedly, it might be:

  • Thermostat issues – sometimes the thermostat is the culprit.
  • Airflow blockages – clogged filters or vents can cause the problem.

4. Blower Keeps Running

Blower stuck on continuously? It could be:

  • Thermostat set to “on” mode – switch it to “auto” for normal cycling.
  • Faulty limit switch – may need to be replaced.

5. Weird Noises

Furnaces make some noise, but banging, screeching, or rattling? That’s not normal. Get a technician on the phone. It could be a worn belt, an ignition issue, or something else entirely.

6. Pilot Light Issues

A flickering or yellow pilot light can signal carbon monoxide danger. Address it right away.

Quick Tips

  • Filter changes: Every three months, or monthly if you have pets or live in a dusty environment.
  • Gas smell: Shut off the furnace, leave the building, and call the gas company if you detect a gas odor.
  • Unusual noises: New or strange sounds from your furnace should be checked out promptly.
  • Maintenance: Schedule a yearly checkup before winter so you’re ready to go.

Now you know the furnace basics. If trouble strikes, don’t try to DIY it — gas furnaces are no joke. Cornerstone Services in Salem has you covered. Keep that home cozy!
