Cracked Heat Exchanger: Do I Need a New Furnace?

Wednesday, January 3rd, 2018

natural-gas-burnerWe’ve written before about the importance of having your furnace’s heat exchanger regularly checked by a professional. This is a part of our routine preventive maintenance program, the Ultimate Service Agreement, and it’s a vital inspection to make sure that a furnace operates as safely as possible. What our technicians look for when they examine a heat exchanger is signs of cracks along it or corrosion that can lead to those cracks. A cracked heat exchanger can allow toxic combustion gases to escape into the airflow moving into the rooms around a house—a dangerous situation!

Furnace owners often feel nervous when they learn their furnace may pose a safety risk. This leads to the question whether they should have the furnace repaired—which means replacing the heat exchanger—or instead have a new gas furnace installed.

Electronic Ignition in a Furnace: Why It’s Better Than a Pilot Light

Wednesday, November 15th, 2017

inside-a-gas-furnaceIf you’ve had the same furnace in your home for many years, you’re probably accustomed to it having a pilot light. If you have newer furnace, or you’re planning on having one installed in the near future, it probably doesn’t use a pilot light at all. Instead, an electronic ignition system ignites the burners. In fact, you rarely see standing pilot lights on newly manufactured furnaces anymore. Why did this change happen? Let’s take a look.

Why Furnace Repair Is Not a “Do It Yourself” Job

Wednesday, January 21st, 2015

We understand that many homeowners want to save money where possible, and that often means picking up a toolkit and an instruction book and attempting to handle repairs around the house on their own. Going “do-it-yourself” is fine for some jobs, such as trying to fix a doorbell or repair broken hinges on cabinet doors. But there are limits to what amateur work can do—and what amateur work should do. A good example is repairing a furnace. On no account should you ever attempt to fix a broken or malfunctioning furnace on your own. We’ll explain why.

It’s not difficult to receive qualified and professional service for a furnace that is having trouble. You can just pick up the phone and call Purl’s Sheet Metal & Air Conditioning. We have handled furnace repair in Fresno, CA and the surrounding areas for many decades, and our NATE-certified technicians will deliver quality work to quickly restore warm heat to your home.

Why you must leave furnace repairs to professionals

The most common type of furnace found in homes is the natural gas furnace. Any type of appliance that uses natural gas must be left to licensed professionals when it comes to service: installation, repairs, maintenance. In most jurisdictions, it is illegal for a non-licensed individual to work on an appliance connected to a gas line. The reason for this is that gas leaks are extremely hazardous, leading to carbon monoxide poisoning and the risk of explosions. If you tamper incorrectly with a gas furnace, you can create a dangerous slow leak and not even realize it. Never take these types of risks: have professionals with years of experience handle the work so you can relax in peace in your home.

Even without the dangers from carbon monoxide, furnaces would still be problems for amateurs to fix.  Modern furnaces are more complex. Trying to track down the cause of a malfunction is difficult to diagnose without proper training. It is even more difficult to fix without the right tools and proper knowledge. Making the wrong repair is often worse than failing to find the reasons for the malfunction. You shouldn’t take a chance with furnace repairs, so be sure to have licensed service heating technicians work on your furnace.

Finally, professional repairs will go much faster than any amateur work. If you need to have your heat working as soon as possible, the quickest route is call the professionals. Call the team of trained and skilled professionals at Purl’s Sheet Metal & Air Conditioning for furnace repair in Fresno, CA. Contact us when you need help with your home’s furnace.

Repairs Your Gas Furnace May Need

Friday, October 17th, 2014

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.
