Nothing is more frustrating than hearing unusual noises from your furnace, especially in the middle of winter. Whether it is a minor component failure or a serious safety concern, ignoring these sounds can lead to more extensive heating repairs or even a system shutdown. If you hear strange noises when your HVAC system is running, it may be time to call a professional. As a reputable HVAC company, Service Hero can have a technician at your home in no time, addressing the root cause to keep your indoor spaces comfortable.
We had a main line drain clog under the house. Russell was our technician and approached the problem from outside the house, working retrograde from a trap in the front yard. I was skeptical but it worked when my efforts with a cable inside the house had failed. He was very professional and pleasant to deal with. We asked him to install a cleanout closer to the house for future use and we were very satisfied with the work.
Tyler is the best! He came to our parent's house, knew exactly what the problem was, and explained it to us without the typical guesswork. I'd recommend him any time you need a good plumber.
Overall, It was a very good experience with the Service Hero team. I was able to schedule an appointment late in the night. They are truly 24x7. The help desk team was very professional, courteous, and friendly. All responses were timely. The field technician showed up on time and diagnosed the issue accurately. Kudos to the Service Hero team!
Unusual noises rarely raise concerns, especially when the system is functioning as expected. However, they indicate a wide range of issues, from minor wear and tear to restricted airflow and loose parts. A system that struggles to maintain the desired atmosphere uses more energy and shortens its lifespan. As a homeowner, recognizing these unusual sounds and acting quickly can help you and your loved ones stay warm and safe all winter long.
One of the most common signs you need professional furnace repair services is persistent rattling or vibrations. If you turn on the HVAC system and hear these noises, you may be dealing with loose panels, worn blower components, or unsecured duct connections. Over time, vibrations can escalate into severe internal damage, turning minor fixes into costly repairs. If your heater vibrates or rattles when it turns on, shut it off quickly and call a trusted HVAC company in La Habra, CA to inspect it.
Tailored services to meet your specific needs and budget, ensuring optimal performance and comfort.
A whooshing or high-pitched noise often means restricted airflow. This is usually a simple clogged or dirty filter, but recurring noises even after changing air filters can signal a gap in your ducts. The whistling sound is air escaping, forcing your system to work harder and use more energy. Addressing airflow issues can improve performance and prevent overheating due to cycling on and off often.
If your system makes a loud bang when starting, it could be delayed ignition, a scenario where gas builds up before the furnace is lit. This is a red flag you shouldn’t ignore, as it can worsen and stress the heat exchanger, posing serious safety risks. Sometimes, these noises may also come from expanding ductwork as it heats up. A professional technician can pinpoint the root cause and assess the extent of the damage to determine if a complete replacement is needed.
A soft click when your furnace turns on or off is normal. However, recurring sounds during operation may indicate a failing relay or a faulty ignition. If you take several minutes to ignite or shut off your furnace, ticking could be a sign that the ignition control is worn out. Early detection and repair are crucial to prevent a complete system failure during the cold months.
A hissing noise from your furnace can be deceptive, as it might be a leaky gas line or a loose duct connection. If you notice a sulfur smell or the sound continues after the blower stops, turn off the system and call for emergency heating repair services. Gas leaks pose serious safety hazards and require immediate attention.
A general rule of thumb is that new, recurring, or louder noises should be checked quickly by a licensed technician. Unlike DIY enthusiasts, professionals can pinpoint the cause, test for safety concerns, and make the necessary repairs before underlying issues get out of hand. Contact us at Service Hero to book an appointment with our experts and keep your furnace efficient, quiet, and reliable for many years to come.
