Common Furnace Problems

Are you experiencing a stubborn furnace? If your furnace is showing any of the following symptoms, these are considered common and may require a professional for repair.

No Heat of Insufficient Heat

This is obviously an issue when you need heat. There could be many issues causing no heat, so call a professional for diagnostic services.

Frequent Cycling on an off

Also known as “short cycling,” this can cause a surge in energy bills. Address this issue quickly, as it can cause damage over time.

Constantly Running Blower

If your furnace blower runs constantly, two likely reasons should be considered: if the thermostat set to the ‘fan’ setting? The fan limit control switch could also be faulty.

Excessive Noise

Pilot Light Out

The pilot light going out is one of the most common reasons that a gas furnace fails to produce heat. Luckily, relighting your pilot light is fairly simple.

Gas Leak

Gas leaks smell of a strong, sulfuric acid, often described as “rotten eggs.” If you suspect a gas leak, call your local fire department or gas company immediately. Leaking gas can be extremely dangerous and should only be handled by a professional. 

Common signs of gas leaks include:

  • A hissing or whistling sound near the line itself
  • A cloud of dust or white mist near the line
  • Bubbles in your water
  • Dead houseplants
  • Visible damage to your gas line, pipe, or the ground around it

Heating or Cycling Problems

  • Confirm nothing is obstructing airflow (i.e. drapes, furniture)
  • Check the thermostat – Make sure the fan is set to “on” or “auto,” then try to raise the temperate 5 degrees and give it a moment.
  • Check the Filter – Replace dirty air filters regularly.

Relighting your pilot light

  1. Find the pilot light assembly and its reset switch.
  2. Set the reset switch to off.
  3. Wait a moment.
  4. Relight the pilot light – Turn the knob to “Pilot,” and let gas flow to the pilot. Light a lighter or match, then push the reset button. Hold your flame to the pilot light’s opening. Keep the reset switch depressed until the pilot light is burning steadily. Then, release the button.
  5. Observe the furnace.

If you cannot relight the pilot light, don’t hesitate to call us!

Unit Has No Power

Go to your home’s breaker panel and look for the circuit that controls the furnace. You’re looking to see whether it’s thrown to the “Off” position, or whether it’s in the middle.

  1. Manually test the breaker. Flip it back and forth.
  2. Make sure it is staying in the “On” position.

If you still cannot get power, call a professional for help.

Should I Repair or Replace My Heating System?

All homeowners find themselves asking this question eventually. The answer, however, is different for each home and set of circumstances. The following suggestions are based on our years of experience. If the system is less than 10 years old, it is worth repairing, especially if the cost of the repair is reasonable. However, if you have invested in constant repairs over the years – especially on a machine that is 10-15 years old or older, it’s likely ineffective. Don’t throw away hard-earned money on a furnace that will likely break down soon. It makes more sense to invest in a new, energy-efficient heating system that gives you the peace of mind you need for the next several years of unpredictable winters.
