Dependable Heater Services In Houston
When your furnace is tucked away in the back of your house, it’s easy to forget the machine is there. However, loud, ongoing noises can turn your heater from a hidden gem to an all-too-obvious annoyance. Because the furnace is a complex system, it’s essential to understand the unusual sounds it can make and how you can silence them!
If your furnace is making loud noises, Air Tech of Houston AC & Plumbing is here to help. We offer quality furnace maintenance, repair and replacement to solve any problems that arise. Read on to learn why your heating system is acting up and how to fix it!
Some Heater Noises Are Okay!
While some sounds signify a problem with your system, others are perfectly normal! When beginning a heating cycle, your furnace may make a clicking sound as the ignition system starts. Afterward, you may also hear a faint humming noise as the heater warms up your air.
Older systems typically make louder noises because of gradual wear and tear. While an increase in volume doesn’t always require a repair, investing in a new system will give you a quieter, more efficient machine.
Furnace Noises To Listen Out For
Some ongoing noises are not just annoying — they also mean your heater isn’t running efficiently! Luckily, you can use the information below to determine the cause of your issue and what repairs can fix it.
Clicking Sounds From Your Furnace
While a clicking sound is normal when a heating cycle starts, it becomes a problem when it starts to sound like microwaving popcorn. An ongoing popping noise has several potential causes, including:
- Dirty furnace burners
- A broken ignition system
- A cracked heat exchanger
While some of these issues require simple maintenance, a cracked heat exchanger can release hazardous carbon monoxide throughout your home and should be replaced with a new part. Air Tech of Houston AC & Plumbing can help with anything from a tune-up to an installation, so contact us if clicking sounds won’t quiet!
A Humming Heater
Like clicking, humming sounds are normal when your heater starts. But when they become too loud or long-lasting, some maintenance may be necessary. Potential sources of the problem include:
- A weakened blower motor — A faulty motor can damage your house’s heating and usually requires a replacement.
- A failed capacitor — If your capacitor is broken, the blower motor won’t work either. Correcting this complication demands a new installation.
- Blocked ductwork — You can keep your duct system clean by replacing your air filters every few months or calling Air Tech of Houston AC & Plumbing for professional heating repair.
If you hear a persistent hum, checking these parts for damage is the first step to silencing it!
Furnace Makes Scraping Noises
A scraping noise may sound like nails on a chalkboard, but you can fix it yourself! Blower bearings are small pieces that help your furnace run smoothly. When they dry out, the system’s efficiency decreases and creates a loud grinding. You can use a few drops of oil to lubricate them regularly and keep this problem at bay!
Your Heating System Is Squealing
Of the many noises a broken appliance can make, squealing is both unique and irritating. It may occur when the furnace’s blower belt slips out of place or is too loose. You can invest in a new belt for under $10 or use a screwdriver to tighten it so it only gives one-half inch.
Rattling Sounds When The Heater’s Running
It’s hard to attribute a rattling sound to a single cause. Many small parts of your heating system can come loose and move around. Alternatively, a cracked heat exchanger — the most common cause of carbon monoxide leaks — might be the culprit.
A professional tune-up can catch any defective components or our technicians can install a new exchanger before serious consequences arise.
Whistling From Your Furnace
Just like you purse your mouth to whistle, restricted airflow can cause your heater to make a similar noise. Clogged air filters, dirty ductwork or a clogged vent can prevent air from circulating and create an annoying sound effect. Regular furnace maintenance can prevent debris buildup and silence unwanted whistling.
It may seem like pesky problems just won’t end, but by keeping these complications in mind, you can put your heater’s unwelcome music on mute!
