Answers to Your Furnace Repair & Maintenance Questions

Furnace Repair Questions

There are several warning signs that indicate your furnace may need professional repair, including:

  • No heat or weak airflow from vents.
  • Unusual noises, such as banging, rattling, or screeching.
  • Frequent cycling, where the furnace turns on and off repeatedly.
  • Cold spots or uneven heating throughout your home.
  • A burning or musty smell coming from the vents.
  • A sudden increase in energy bills without increased usage.

If you notice any of these issues, contact All Temp Heating & Cooling for a professional furnace inspection and repair.

If your furnace stops running, try these steps before calling for service:

  1. Check the thermostat to ensure it's set to heat and at the correct temperature.
  2. Inspect the furnace filter—a dirty filter can restrict airflow and cause the system to shut down.
  3. Check the circuit breaker to ensure power is running to the furnace.
  4. Look at the pilot light (for gas furnaces) to see if it’s lit.
  5. Contact a professional if these steps don’t resolve the issue.

Furnace noises often indicate an underlying issue:

  • Banging or popping – May be caused by delayed ignition or expanding ducts.
  • Squealing or screeching – Likely due to a worn-out blower belt or motor bearings.
  • Rattling or vibrating – Can indicate loose components inside the furnace.
  • Clicking or buzzing – Could be an electrical issue with the igniter or control board.

If your furnace is making unusual noises, schedule a repair appointment before the issue worsens.

No! If you smell gas, turn off the furnace immediately, leave your home, and call your gas company. A gas leak is a serious safety hazard and should only be handled by licensed professionals.

Furnace repair costs depend on the type of repair, system age, and complexity of the issue. Minor repairs (like thermostat fixes or filter replacements) are more affordable, while major component failures (such as a broken blower motor or heat exchanger) may cost more.

We offer transparent pricing and financing options for larger repairs.

Furnace Maintenance Questions

For best results, schedule furnace maintenance at least once per year, ideally in the fall before winter starts. If you use your furnace heavily, a bi-annual maintenance schedule (fall and mid-winter) can help ensure maximum efficiency.

Skipping furnace maintenance can lead to:

  • Higher energy bills due to reduced efficiency.
  • More frequent breakdowns and costly repairs.
  • A shorter lifespan—lack of maintenance can reduce furnace life by several years.
  • Poor air quality from clogged filters and dirty air ducts.

Regular maintenance helps prevent unexpected failures and keeps your furnace running efficiently.

A professional furnace tune-up from All Temp Heating & Cooling includes:

  • Checking and calibrating the thermostat.
  • Inspecting and cleaning the blower motor and fan.
  • Replacing or cleaning the air filter.
  • Examining electrical connections for safety.
  • Cleaning the burners and flame sensor.
  • Testing for gas leaks or carbon monoxide issues.
  • Ensuring proper airflow and system cycling.

Yes! Homeowners can handle some basic maintenance tasks, including:

  • Replacing the air filter every 1-3 months.
  • Keeping vents and registers clear of obstructions.
  • Checking the thermostat settings for optimal energy savings.
  • Cleaning dust and debris from around the furnace.

However, professional maintenance is still required to inspect internal components, calibrate the system, and ensure safe operation.

Furnace Efficiency & Replacement Questions

A well-maintained furnace lasts 15-20 years. If your system is older than 15 years, frequently breaking down, or becoming inefficient, it may be time for a replacement.

To maximize your furnace’s efficiency:

  • Schedule annual maintenance to ensure peak performance.
  • Use a programmable or smart thermostat for better temperature control.
  • Keep air filters clean to maintain proper airflow.
  • Seal duct leaks to prevent heat loss.
  • Ensure vents and registers are not blocked.

Yes! We provide 24/7 emergency furnace repair services for urgent heating issues. If your furnace stops working unexpectedly, our team is ready to restore comfort to your home as quickly as possible.

Yes! We offer flexible financing options to help homeowners afford major furnace repairs or maintenance services. Our plans include:
