Why You Should Not Delay Your Furnace Repair

Addressing furnace issues quickly is essential for several reasons:

  • Avoiding dangerous conditions: Serious problems with a gas furnace, such as a leaking flue or a cracked heat exchanger, can release combustion products like carbon monoxide into your home. Similarly, faulty electric furnaces can pose a risk of fire.
  • Preventing costly repairs: Minor issues, such as a worn-out belt, can escalate into major problems if left unaddressed, potentially damaging critical components like the blower motor or fan.
  • Staying prepared for sudden cold snaps: Michigan winters are unpredictable, and a malfunctioning furnace can leave your home vulnerable to extreme cold.
  • Extending system life span: Regular and prompt repairs help prolong the life of your furnace, maximizing your investment and reducing the need for premature replacements.

A Guide to Common Furnace Issues

Understanding common furnace problems can help you recognize when professional repair services are needed. At Randazzo Heating, Cooling, and Electrical, we receive countless calls for furnace repairs each year, and here are some of the most common issues we encounter:

  • Failure to start: This can be caused by a tripped circuit breaker, a faulty pilot light or igniter or a defective control board or thermostat.
  • The furnace turns on and off quickly: If your furnace does not run for more than a minute, the flame sensor may be dirty or faulty, or the thermocouple may have failed on older models.
  • Low heat output or poor airflow: This problem can often be as simple as a clogged air filter or a dirty blower fan. Other causes include blocked vents, dirty burners, or a failed heating element.
  • Cool air from the vents: If the furnace’s limit switch has failed or is set improperly, it may turn the fan on before the burners or heating element has started working, blowing cool air into your home.
  • The fan runs constantly: The fan should turn on and off to help heat your home more efficiently and protect the heat exchanger from damage. If the fan limiter is faulty, the fan may run constantly.

Our expert technicians are experienced at diagnosing and repairing these common furnace issues, ensuring your heating system functions optimally.

Furnace Repair FAQs

We recommend servicing your furnace once a year to prevent furnace breakdowns and costly repairs. Scheduling furnace maintenance services in the fall can ensure it receives all the care it needs to prepare for the cold.

If you’re having problems with your furnace, ensure your thermostat is set to heating mode and the desired temperature is set correctly. Make sure the air filter is not excessively dirty or clogged and none of the vents are blocked. If the furnace does not turn on, turn its circuit breaker off and back on to reset the control board and ensure the breaker is not tripped.

Replacing a furnace requires specialized knowledge and expertise to ensure safety and efficiency. DIY installations can lead to improper setup, posing risks such as gas leaks or electrical hazards. Trust our certified technicians at Randazzo Heating, Cooling, and Electrical to handle your furnace replacement precisely and carefully.

Regular maintenance, timely repairs, and routine filter changes can significantly extend the life span of your furnace.
