Common Furnace Noises and What They Mean
There are several noises your furnace may make that can indicate the cause of a potential problem. Here are the most common furnace noises and what they may be telling you about your heating system.
Rattling
Rattling is one of the most common noises that can come from your furnace. This sound typically indicates that there may be loose panels, screws, or other internal components moving around.
Squealing
The sound of squealing often indicates a slipping or faulty fan belt in your furnace that requires repair. This sound should get your attention, especially if you smell burning rubber along with the noise. These signs point to a worn-out blower belt that needs replacement.
Whistling
High-pitched whistling or hissing means that hot air may be escaping through a leak in the ductwork. It can also be due to clogged air filters that are making it harder for hot air to move through.
Buzzing
Buzzing or vibration noises indicate you may have an electrical issue on your hands. If your furnace buzzes when it kicks on, the transformer box may be loose or worn out. In older furnaces, buzzing typically indicates that the transformer box needs to be replaced.
Booming
If you hear a banging or booming sound coming from your furnace, pay attention to when it occurs. Booming sounds that occur about a minute or two after turning on your furnace can mean that dirty burners are delaying ignition. Gas builds up during the delay, resulting in a boom when the furnace ignites. Banging or booming can also indicate expanding air ducts.
Clicking
Clicking is a normal noise for homeowners with furnaces. Gas furnaces emit a clicking noise when the ignition system engages after the thermostat kicks in. This is not a cause for concern and indicates normal functioning.
When a Simple Filter Change Can Solve the Problem
Sometimes, a simple filter change can resolve the strange noises. This is because clogged or dirty air filters restrict airflow, causing a furnace to have to work harder. This overexertion can result in strange noises and strain on the heating system.
Other signs that you need to change your air filters include:
- Short-cycling (furnace frequently turns on and off)
- Higher energy bills
- Reduced airflow from vents
- It’s been more than 90 days (most air filters are designed to last 30-90 days, depending on the filter)
If changing the air filters in your home doesn’t resolve the strange noisemaking, call an HVAC professional, like G & G Heating.
Signs You Need Professional Furnace Repair in Olympia
How do you know you need furnace repair services in Olympia? A malfunctioning furnace can cause discomfort, especially during the colder months of the year. Knowing when you need furnace repair or replacement helps to minimize downtime and restore comfort as soon as possible. Here are some top signs you could use professional furnace repair:
Strange Noises
Rattling, banging, booming, and other loud noises are not only a nuisance, but can indicate your furnace is overheating, causing metal to expand. If you have a newer system, dirt could also be the culprit. Try changing all your air filters and calling for professional duct cleaning.
Inconsistent Temperatures
If your heating system is blowing cold air or providing inconsistent heating, a certified HVAC technician can assess and diagnose the problem. Uneven heating is a common furnace problem that often can be addressed by fixing closed dampers. In older models, it may indicate unit replacement is necessary.
Unexplained High Energy Bills
If your energy bills have skyrocketed for no apparent reason, it signals that the efficiency of your heating system may have tanked. An old and inefficient furnace can quickly raise your utility costs. Call for a professional opinion on whether furnace repair or replacement is recommended.
Carbon Monoxide Leaks
Lastly, if your furnace is emitting carbon monoxide, call for emergency furnace repair services immediately. Carbon monoxide (CO) is a dangerous, odorless and colorless gas that can cause sickness or even death. Yellow flames in your furnace can signal an issue with CO, but first and foremost, a CO detector will alert you of its presence.
How Regular Maintenance Prevents Future Repairs
Regular furnace maintenance is the key to keeping your heating system in tip-top shape. From early detection to enhanced safety, routine maintenance prevents costly future repairs.
Early detection
When you get your furnace inspected regularly, technicians can identify minor issues, like small leaks or worn out parts that need replacement. By identifying issues early, you can prevent bigger damage to important components.
Extend equipment lifespan
Regular maintenance extends the lifespan of your unit by keeping it in optimal working condition. Performing regular tasks, like cleaning and lubrication, prevents the need for costly furnace repairs. Prolong the life of your equipment and avoid future issues by starting a furnace maintenance plan.
Improved performance
A well-maintained heating system will be more energy efficient and lead to better performance all around. This can result in lower energy bills, less repairs, and enhanced comfort.
Enhanced safety
Completing routine maintenance enables technicians to identify potential hazards, such as electrical problems that could cause a fire or other safety issues. Protect your family’s safety by investing in routine furnace maintenance.
