Signs You Need Furnace Repair

A malfunctioning furnace can leave your home cold and uncomfortable, leading to higher energy bills and potential safety risks. Watch for these warning signs that your furnace may need professional repair:

No Heat or Weak Airflow

If your furnace blows cold air or airflow is weak, possible causes include:

  • Clogged air filters restricting airflow.
  • Blower motor issues preventing heat distribution.
  • Pilot light or ignition system failure in gas furnaces.

Strange Noises During Operation

Unusual sounds like banging, rattling, or screeching may indicate:

  • Loose or broken internal components.
  • Worn-out belts or bearings in the blower assembly.
  • Delayed ignition causing mini-explosions inside the heat exchanger.

Frequent Cycling or Difficulty Staying On

If your furnace turns on and off frequently, it could be due to:

  • Overheating caused by dirty filters or airflow blockages.
  • Malfunctioning thermostat sending incorrect signals.
  • Electrical control issues disrupting operation.

Yellow or Flickering Pilot Light (Gas Furnaces)

A yellow pilot flame instead of blue may indicate:

  • Carbon monoxide buildup, which can be dangerous.
  • Ventilation blockages or burner issues.
  • Gas supply problems requiring immediate attention.

Rising Energy Bills with No Change in Usage

  • Reduced efficiency due to dirt buildup on components.
  • Furnace struggling to maintain the set temperature.

FAQs: Furnace Repair & Maintenance
in Marietta, PA

Frequently Asked Questions About
Furnace Repair & Maintenance

Your furnace may need professional repair if you notice:
  • Cold air coming from vents instead of warm air.
  • Weak airflow or uneven heating throughout your home.
  • Strange noises like banging, rattling, or squealing.
  • Frequent cycling, where the furnace turns on and off too often.
  • A yellow pilot light, which may indicate carbon monoxide issues.
  • A sudden increase in energy bills without changes in usage.

Some of the most frequent furnace issues include:
  • Dirty or clogged filters restricting airflow.
  • Pilot light or ignition system failure in gas furnaces.
  • Faulty thermostats causing temperature inconsistencies.
  • Blower motor malfunctions leading to poor heat circulation.
  • Cracked heat exchangers, which can pose safety risks.

Most furnace repairs can be completed in 1–3 hours, depending on:
  • The type of issue (minor fixes take less time, major repairs take longer).
  • Availability of replacement parts if components need to be swapped out.
  • The furnace brand and model (some systems require specialized repairs).

A professional furnace tune-up from 717 Mechanical LLC includes:
  • Air filter cleaning or replacement to improve airflow.
  • Checking and calibrating the thermostat for accuracy.
  • Inspecting the blower motor, fan belts, and heat exchanger.
  • Cleaning the burners and checking gas pressure in gas furnaces.
  • Examining electrical connections and safety controls.
  • Ensuring vents and ductwork are free from blockages.

We recommend annual furnace maintenance to:
  • Ensure maximum efficiency before the winter season.
  • Reduce energy costs by keeping your system running smoothly.
  • Extend the lifespan of your furnace.
  • Prevent small issues from becoming expensive repairs.
For homes with high heating demands, bi-annual tune-ups may be beneficial.

Some basic maintenance tasks homeowners can handle include:
  • Changing or cleaning air filters every 1–3 months.
  • Keeping vents and registers clear of dust and obstructions.
  • Checking thermostat settings for proper operation.
However, professional maintenance is necessary to inspect and clean internal components, electrical connections, and gas burners.

Strange furnace noises often signal mechanical problems:
  • Banging or popping – Delayed ignition or expanding air ducts.
  • Rattling – Loose internal components or ductwork issues.
  • Squealing – Worn-out blower motor or belt.
If you hear unusual sounds, schedule a repair before the issue worsens.

If your furnace won’t start, try these steps:
  • Check the thermostat settings and ensure it's set to heat.
  • Replace the air filter if it’s clogged.
  • Ensure the circuit breaker hasn’t tripped.
  • Verify the pilot light is lit (for gas furnaces).
If these don’t resolve the issue, call 717 Mechanical LLC for a professional diagnosis.

Frequent cycling can be caused by:
  • Dirty air filters restricting airflow.
  • A faulty thermostat misreading temperatures.
  • An oversized furnace that heats too quickly and shuts off.
A furnace tune-up can help determine the root cause and restore normal operation.

A well-maintained furnace typically lasts:
  • 15–20 years for gas models.
  • 20–30 years for electric models.
  • 10–15 years for oil furnaces.
Regular maintenance and timely repairs help extend your system’s lifespan.
