3 Reasons Why Your Furnace Won’t Ignite

Friday, March 21st, 2014

For a gas furnace to work, the burner needs to ignite to create the combustion gas that transfers heat to air. If the burner won’t ignite, the furnace will not generate heat, and you’ll only receive room temperature air from your vents.

A furnace can fail to light for different reasons; we’ll look at a few of the more common. In most cases of furnace burner failure, you should never attempt to solve the problem on your own. It is dangerous to tamper with any system connected to a gas line without proper training because of the risk of toxic gas exposure and explosions. Instead, shut off the gas to the furnace and call heating professionals. Cowboys Air Conditioning & Heating can handle your furnace repair and maintenance in Fair Oaks, TX. Our technicians are available 24/7.

3 Culprits Behind a Furnace Failing to Ignite

  1. Blown fuse/tripped circuit breaker: Modern gas furnaces do not run entirely on natural gas. Electronic ignition systems have started to replace standing pilot lights, which has resulted in more efficient furnaces. But this also means that if the furnace trips a circuit breaker, the electronic ignition will not turn on to ignite the burner. Check your circuit panel or fuse box to see if this is the case. Reset the breaker or replace the fuse and try to start the furnace again.
  2. Gas valve or gas line trouble: The issue with the furnace’s failure to ignite may lie in the gas line itself: the burner is not receiving enough fuel to start up. This might be trouble in the gas valve (a safety mechanism may have closed it, or it’s stuck) or an issue deeper down in your gas supply line. Whatever the cause, it’s work for a skilled technician only.
  3. Dirty or rusty burner: One of the reasons that it’s important to keep the filter of your furnace clean with regular replacements is to prevent dirt from getting into the cabinet and along the burner. A layer of grime will block the oxygen necessary to allow the burner to ignite. Rust flakes inside the burner will also cause this. You should not attempt to clean the burner yourself; it needs to have a professional remove the unit and clean it.

Sign Up for Regular Maintenance for Your Furnace

You can avoid most troubles with furnace ignition with a preventive maintenance program. An annual visit from a heating technician will make sure that the burner, the pilot, and the igniter are clean and in good shape. The technician will also check that your furnace is running without safety issues.

Cowboys Air Conditioning & Heating has an excellent preventive maintenance agreement that will keep your heating and cooling tuned-up with two maintenance visits per year. You’ll receive other benefits as well. Give us a call today to find out more, or if you’re in need a heating repair service in Fair Oaks, TX.

How Dust and Dirt Can Affect Your Furnace

Thursday, February 27th, 2014

Dust is a major enemy of many appliances in your home, not to mention your house’s general appearance. One appliance in your home that can suffer serious consequences from a dust infiltration is your furnace, whether it’s gas-powered or electrical.

Dust and Your Furnace—The Major Problems

  • Clogged air filter: The filter of your furnace is its main defense against dust getting through to contaminate the interior. In order for it to do its job, you need to change it ever month during heating season. If too must dust clogs it, it will reduce airflow to the furnace and end up cutting into its heating power.
  • Motor damage: If dust enters the furnace cabinet, the components it will affect the fastest are the motors. Dusty motor bearings and pistons will cause a motor to burn out, and it will need replacement. Listen for screeching and shrieking noises from the cabinet, or acrid smells from the vents, to warn you of this.
  • The burner won’t ignite: For a gas furnace, a dust contamination along the burner unit will prevent the gas jets from igniting because of lack of oxygen. Professionals will need to remove the burner unit and clean it.
  • Reduced efficiency from contaminated ductwork: As dust and dirt begins to build up inside ductwork, it creates resistance against the airflow from the furnace’s air handler. This will make the furnace work harder, and in turn cause its components to begin to wear down faster. Regular duct cleaning will help prevent this—and will also lead to cleaner indoor air for your home.
