Repairs Your Gas Furnace May Need

Furnaces are one of the more common ways to provide heat for homes. A properly cared-for furnace can deliver high heating levels and operate for many years with only occasional repair needs. If you have a furnace installed in your home, make sure that you schedule annual maintenance for it during the fall to lower the chance that you will have to call for repairs during the winter.

There is no way that you can avoid all repair needs for a furnace, no matter how well you keep the system maintained. Below are some repairs that a furnace may require during its service life to keep it working efficiently, effectively, and safely. If you notice an issue with your furnace—such as a drop in heating levels or strange sounds coming from the cabinet—call for furnace repair service in Fresno from Purl’s Sheet Metal & Air Conditioning. We have 60 years of experience servicing heating systems in the Central Valley.

Some Common Furnace Repair Needs

  • Replacing cracked heat exchangers: The heat exchanger is the component of a furnace responsible for transferring heat from the combustion gas to the air from the blower. If a heat exchanger starts to develop corrosion with age, it may lead to cracks and exhaust gas escaping from the furnace. This is a potentially dangerous situation, and a technician will need to replace the exchanger should it happen. Technicians will notice issues with the heat exchanger during a regular maintenance visit and arrange for the repair work to replace it.
  • Ignition repair: Most modern furnaces no longer use a standing pilot light, but instead ignite the gas jets along the burner using electronic ignition. This ignition can malfunction or fail, which will result in either delayed ignition or the furnace burners not coming on at all. Don’t try to repair this problem on your own: call for professional assistance to repair or replace the electronic ignition.
  • Blower motor repair: The motor that runs the blower can overheat if it develops too much stress on its mechanical parts due to dust, dirt, or lack of lubrication. An overheated motor will burn out and stop working if it doesn’t receive repair work. If you detect airflow issues or discover that the blower will not turn on at all, call for repair technicians right away.
  • Recalibrating the thermostat: Sometimes what seems like a furnace malfunction actually comes from a miscalibrated thermostat that is reading temperatures incorrectly and turning the furnace on and off at incorrect times. Skilled technicians will know how to track down the trouble to the source and fix it.

We must emphasize that you should never attempt repairs to a gas furnace on your own because of the potential safety risk. Call on the experienced team at Purl’s Sheet Metal & Air Conditioning for your heating repairs in Fresno, CA. We are on call seven days a week.
