Creaking heat vents can be fixed by following these steps:
1. Identify the source of the creaking noise. It could be caused by loose screws, worn-out parts, or debris.
2. Tighten any loose screws using a screwdriver. This may solve the problem if the creaking is due to loose parts.
3. Clean the vents by removing any debris or dust that may be causing the creaking sound. Use a vacuum cleaner or a brush to clean the vents thoroughly.
4. Lubricate the moving parts of the vents with a silicone-based lubricant. Apply the lubricant to hinges, pivots, or any other moving parts to reduce friction and eliminate creaking.
5. If the creaking persists, consider replacing worn-out parts or contacting a professional for further assistance.
It’s a frequent occurrence: you hear the furnace starting up with a whoosh, the fan buzzing softly, and warm air flowing from the vents. Then, the creaking of your heating vents becomes a concern. You hear different ticks at varying volumes in different areas of the house, one room goes “bang,” and the living room vent produces a creaking sound.
While you might be accustomed to these familiar sounds, the prolonged and repetitive creaking or ticking might have finally gotten on your nerves. Fortunately, fixing your creaking heat vents is possible, particularly if you have a solid understanding of the problem.
What Causes Ticking Noises?
There are many potential reasons for noisy ducts and vents, some of which are easier to fix than others. Although there are many things you can handle on your own, it’s important to know when to call in a professional.
For example, frequent ticking sounds can signify different issues depending on whether you’re running the AC or heat. If your cold air system is working and your AC unit is ticking, it’s likely that the compressor is failing or overheating. This is a component that professionals should replace.
If your furnace is ticking, that’s the ignition for your burner. If it clicks only a few times and you hear the flame catch, it’s probably okay, but constant or prolonged clicking indicates that the gas isn’t igniting, which can be a huge issue. Again, this is a fix that requires a professional.
Loud Banging Noises
Loud banging noises are almost always the result of cold metal air ducts expanding when hot air flows through them. This can be a DIY fix, but it takes time and may require getting very dirty.
Locate your ducts, which can be in the floor or ceiling. Then, clean your ducts with water and a soft cloth. After that, seal and insulate your air ducts to reduce expansion and contraction noises. Once sealed and insulated, there should be less of a pressure difference, which is what causes metal ducts to pop out or in. The insulation will help muffle the noises that occur anyway.
You may also replace your rectangular vents with circular vents. The circular shape results in better airflow and less expansion and contraction, which reduces noise.
Creaking Vent Noises
Creaking vents occur when the duct or vent rubs against wood as it expands and contracts. This can be a simple DIY fix.
By placing a rubber sheet between the metal duct and the wood, you can prevent rubbing and creaking noises. Sealing and insulating your ducts will also help by reducing expansion and contraction, making your HVAC system more efficient and resulting in savings every month.
Other Disconcerting Noises
There are many other strange noises that may make you uneasy regarding your HVAC system’s operation. This can range from thwapping or clanking due to fan blades hitting something dangling in them to rattling and screeching caused by a loose object in your ducts or ungreased moving parts.
DIY Furnace and Duct Inspection: When to Call a Pro
For those who are skilled in furnace and duct maintenance, it may be tempting to take a look inside and inspect it yourself. However, it’s important to consider your level of expertise before doing so. Don’t forget to weigh the value of your time, safety, and comfort. If you feel unsure about your abilities, it’s best to seek the help of a professional.
