As the temperatures drop and your furnace kicks on for the first time this year and begins it’s six month journey heating your home and keeping your family warm this winter you may hear noises you haven’t heard in awhile.
While it is difficult to diagnose an exact issue and repair needed going by the noise alone it can give you and your service tech a good starting point. Below is a list of a few of the noises you may hear coming from your furnace and what the issue they may be linked to.
Grinding- This is a telltale sign that you have a problem that needs addressed ASAP. More than likely your furnace has parts that are broken or loose and they are rubbing up against other parts. Don’t wait and give us a call as soon as you hear this sound. Additional damage and cost could add up if this is left unattended.
Rattling- If you hear a ratting noise traditionally this is not a huge issue. It could be something as small as a loose screw or something needs tightened down. You will want to get to the bottom of the situation but typically not an emergency.
Whistling- A whistling sound is almost always a sign that you have air flow restriction. The sound you hear is your furnace trying to draw air and move it where it can’t, which creates gaps. We recommend replacing your air filter as that clears up the issue most of the time. If you replace your filter and still hear the same sound. It’s probably time to give us a call.
Buzzing sounds-Again, like the grinding this should be looked at by a professional ASAP. We’ve seen a numerous amount of these sounds end up as an electrical connection issue.
Banging or loud pops- This sound often comes from your ductwork and typically happens when your furnace kicks on/off. This is pretty common as metal will expand and contract
Squealing noises- Belts on furnace blowers just like the belts on your car will need replaced from time to time. As they begin to wear down you may hear that annoying whining or squealing noise.when your furnace kicks on/off.
This is not an all-inclusive list and when in doubt give us a call and we can dispatch one of our certified technicians to come out to diagnose and repair your furnace issues and maybe at a price less than you expect.
