Furnace Repair and Maintenance: Guidance from an HVAC Technician

As an HVAC technician, I often service furnaces that require professional attention. A well-maintained furnace also provides consistent heating but also reduces costly repairs. In this article, I’ll explain common heating system issues, essential maintenance tasks, and situations requiring an HVAC technician.

Typical Heating System Issues

Furnaces can develop various failures over time. Here are some of the frequent problems I handle in my work:

  • Furnace Won’t Turn On – This could be a result of a faulty thermostat, blown circuit breaker, or pilot light problems.
  • Weak or No Airflow – Clogged vents can restrict airflow.
  • Strange Noises – Clanking or grinding noises often indicate a loose component.
  • Short Cycling – This could be due to a overheating issue.
  • Intermittent Ignition Failures – A faulty thermocouple could hinder the furnace from producing consistent heat.

Essential Heating System Care

Proactive maintenance is necessary to keep your furnace running. Here are the best maintenance practices:

  1. Keep Air Filters Clean
  2. A blocked air filter restricts airflow, leading to overheating. Change the filter at least quarterly.
  3. Inspect and Clean the Blower Motor
  4. The blower motor moves warm air via the ductwork. Lack of lubrication can lead to mechanical failure.
  5. Test the Thermostat
  6. A miscalibrated thermostat can lead to unbalanced temperatures. Monitor the temperature settings to ensure the system is functioning properly.
  7. Inspect the Heat Exchanger
  8. A cracked heat exchanger poses a risk of carbon monoxide—a potentially deadly gas. If you notice discoloration, shut off the furnace and seek expert help.
  9. Keep Vents Clear
  10. Blocked vents or flue pipes can cause poor heating performance. Remove obstructions to avoid heating problems.
  11. Plan for Routine HVAC Servicing
  12. A yearly checkup by a licensed HVAC technician reduces the risk of potential failures. This includes testing safety controls.

Situations Requiring HVAC Service

While basic maintenance tasks can be handled by homeowners, complex furnace problems should be addressed by an HVAC technician. Consider calling a professional if:

  • The System Doesn’t Turn On – If resetting doesn’t fix the problem, a technician should inspect the system.
  • You Smell Gas or Burning Odors – Shut off the furnace immediately.
  • Unusual Sounds Persist – Grinding sounds could mean loose components.
  • Your Furnace is Running Less Efficiently – Higher costs suggest a struggling system.

Final Thoughts

Taking care of your heating system ensures reliable heating and improves the system’s lifespan. Staying on top of furnace care can prevent costly repairs. However, for major issues, get expert assistance. A experienced heating technician will fix dangerous furnace issues and ensure optimal heating.
