When was the last time you swapped out your furnace filter? If the answer is more than a few weeks ago, it might be time to check it, especially if you have pets. When running, your heating system pulls in dust, dander, and dirt. This is kept out of the mechanical parts by your furnace filter. A clogged filter restricts airflow, making your heating system work harder. Replacing it not only helps efficiency, but also improves air quality.

Your thermostat is responsible for signaling your furnace when to turn off and on to maintain the set temperature. If it’s not working properly, you’ll struggle to get warm. For instances where the thermostat may be at fault, make sure its batteries are good, if it uses any. Also, double-check that it is set to HEAT with the run method on AUTO.

Sometimes the pilot light or surface ignitor will fail and refuse to light the burners. If this happens your furnace won’t be able to heat the air, leaving you in the cold. To prevent this, have it checked and cleaned regularly by an Santa Clarita-area HVAC professional. If it's the middle of winter, though, just give our Santa Clarita HVAC contractors a call at 818.697.4609 instead.

The furnace exhaust blower is what takes the combustion gasses out of the heat exchanger and vents it safely outdoors. If this component fails, the furnace will cycle on and off or shut down. Regular inspections and maintenance visits can prevent this from happening.

The blower motor is essentially what keeps the air moving around your home. Should this component fail, it doesn’t matter how efficient your furnace is, the hot air won’t be distributed around your home. The blower can fail from overheating or from it becoming clogged with debris. Have your ducts cleaned and your furnace tuned up to keep the blower working effectively.

The heat exchanger is one of the most important components of a conventional furnace. It is the component that safely transfers heat from the flame into heated air that is circulated in the home. When the heat exchanger develops holes or cracks, replacing it can be quite expensive. Some people prefer to simply replace their furnace. An expert evaluating your system can best advise you. If the stress on your heat exchanger is due to excess cycling due to having too large of a furnace, only replacing the heat exchanger will result in the same problem developing again.

If your furnace in Santa Clarita isn’t keeping up with the thermostat, several issues could be at play. The most common is a clogged air filter that’s restricting airflow and lowering efficiency. Other potential reasons include:

• An old or failing furnace
• A malfunctioning thermostat
• Blocked or closed vents
• Problems with the pilot light or flame sensor

When your furnace in Santa Clarita blows cold air, it might be due to something simple or more complex. Start by checking your thermostat to ensure it’s set to heat. If the thermostat isn’t the issue, the problem could be with the flame sensor or ductwork leaks. Our technicians can quickly diagnose and fix the problem for you.

Furnace repair costs in Santa Clarita vary based on the issue.

Water leaking from a furnace might seem odd, but newer high-efficiency systems often create condensation. Common causes include:

• Clogged condensation drains
• A damaged heat exchanger

Older furnaces in Santa Clarita may have a standing pilot light that occasionally goes out. To safely relight it:

• Turn off the gas and wait five minutes.
• Adjust the gas valve to “Pilot” and press the reset button.
• Use a long lighter to ignite the flame.
• Once the light is steady, release the button and turn the valve to “On.”

If it doesn’t stay lit, contact Rays for assistance.

A cracked heat exchanger is a serious safety issue for furnaces in Santa Clarita. It can cause incomplete combustion, allowing carbon monoxide—a deadly gas—to leak into your home. Replacing a heat exchanger is costly, so it’s often more economical to replace the entire furnace. Our experts can assess the best option for your home.

If your furnace seems to be running endlessly, it’s likely due to a thermostat malfunction, clogged air filters, dirty flame sensors, or an obstructed flue. These issues waste energy and can overheat your system. Call 818.697.4609 for fast diagnosis and repair.

A cheap furnace repair might seem like a good deal, but it often leads to problems like:
