Weird sounds from your air conditioning or heating system are never a good sign. The ultimate thing you want to hear on an extreme winter or summer day when you want to relax is some weird noise coming out of your HVAC system. 

So, if your heating system starts making odd noises at the end of the season, it is perhaps time to call experts for your heating repair in Eden Prairie to help you, as it could be challenging to self-identify the issue. 

Seven Frequent HVAC Voices and Their Indications

Here are some heating and cooling noises and their indications. 


A shrieking sound could indicate a faulty fan belt in the compressor. In such a case, you must replace the defective fan belt. In addition, the sound could also imply that the motor requires lubrication, which you may or may not be able to perform depending on the make and model of your heating system.


This noise could indicate that something got trapped in the motor blades of the blower. It’s easy to determine if this is the issue if the noise comes in waves with the airflow. While this scenario may not be crucial to the furnace’s continued operation, the impending object may be causing unnecessary wear and tear.


These noises, similar to “thwapping,” could be linked to the furnace’s air compressor arrangement or motor and are most likely the result of something being weak or broken. 

Shut down the network until you can get assistance if you notice louder clanking sounds while the blower unit is working. Something must have broken or become disengaged at this point.


Is your air conditioner making this prevalent HVAC noise? If that’s the case, it could be a compressor issue. It is also possible that the unit remains frozen due to a coolant leak. It could also be a loose part throbbing. However, it would be best if you got it inspected.


When the furnace tries (and fails) to light (or relight) from a gas heater or electronic ignition, it makes a booming noise. As a result, there is an increasing build-up of gas within the fuel tank, which will suddenly ignite. To cut a long story short, this is not a good situation, and you should contact an HVAC technician immediately. A build-up of these particles was most likely to blame for the problem.

Clicking Frequently

If you hear clicking from your HVAC system, it’s usually the outside blower motor or the inside air handling unit. 

Some conceivable reasons can easily get identified by a technician. First, is it possible that the clicking is rising from the furnace? Clicking should be a pleasant sound if the weather gets colder and you turn on the hot air for the first time in a long time.


It is a familiar noise that comes from your ductwork when you do not turn on your HVAC for a long time. This sound comes from metal ducts dilating as warm air rushes through them.
