Possible Sources Of HVAC Noise

There are many possible places that an HVAC system can go wrong and start to make noise, and it's often helpful to isolate the area of your problem so that you know what kind of specialist to hire. Here are some potential areas to check for an HVAC problem.

Listen to the Furnace

Your HVAC system will make some kind of noise as part of its normal operation, but normally this should be at such a low volume that it doesn't disturb your daily life. But if you are hearing noises, one of the first things to do is listen to your furnace. You may want to write down some descriptions of what you hear. Do you notice rattling, wheezing, thumps? Is the noise continuous, or are you more concerned about intermittent loud noises? With the furnace, there could be many potential problems to call out a furnace repair technician for. One is that the motor could be on its last legs. Another may be that the combustion tank is not working efficiently and so the system is struggling. You could also have a problem with a clogged filter that is causing a rattling or wheezing noise.

Listen Through the House

You may also want to check in each room to see if the noise gets louder in any one area. If you can trace the loud HVAC operation to a specific room, it is possible that you have discovered a problem HVAC duct. The sealant between each section can come undone, which means that the pieces may creak or rattle as they move or hit each other. An HVAC team can easily seal the connections between two HVAC sections in most cases. And you will also benefit from a lower energy bill since sealing these cracks can promote energy efficiency for your HVAC system.

Check the AC Unit

Your air conditioner might be the source of problems as well. One in particular is noise from your outdoor AC unit. If the unit is in your yard in a place that you don't normally go, you might not even notice that there is an object stuck in the unit. But those noises can echo through your HVAC ductwork if the jam is big enough. You can often diagnose this problem by visually inspecting the unit, but you might need the help of an air conditioning contractor if you can't easily grab the object and remove it from the unit. Be sure not to stick anything into the unit when it is in operation.

Avoiding Air Conditioning Problems

Last summer the unthinkable happened. My air conditioner failed on a day when it was over a hundred degrees outside. I was devastated, frustrated, and most of all, sweaty. Fortunately, a kind repair technician came out and helped me to get the system fixed the same day. After things were working, I took the time to ask how to avoid air conditioning problems in the first place. The technician gave me some great tips, including avoiding blocking my air returns. I also learned how to replace my air filter, which made a huge difference. Check out this blog to learn about HVAC.
