When it starts up or when it shuts off is never a normal symptom, hearing abnormal noises emitting from the air conditioner. The air conditioning system is protesting that there is an issue that needs to be addressed when you hear these noises. To escalate into something more costly as a domino effect takes place inside the AC’s mechanical structure happens when you brush off the unusual noises. All of the moving parts work together to effectively do their job in order for the air conditioner to produce comfortable temperatures inside your home. Putting extra strain on those parts wear down all the more. When components wear, other parts will try to compensate. It is important to avoid extra costs and additional wear on your cooling system where many issues can be a simple fix when the noises manifest. When it starts up and/or shuts down, we at Air Supply Heating & Air Conditioning would like to share a few reasons as to why your air conditioner is making strange sounds.
Squeaky Air Ducts
From the constant temperature and pressure changes in sheet metal air duct systems, it is common to hear loud creaking noises as the air ducts expand and contract. There is a possibility that the air ducts may have a leak or are disconnected where these sounds can be normal. Due to poor ductwork, the cool air is not able to come through the vents efficiently.
Air Handler / Fan Rattling Noise
Often stemming from many underlying issues, the air handler or fan can be causing the blower wheel to bang against another part of the unit. The unusual clanking sounds can be produced from where the fan’s mounts can get loose and throw it off balance as it slows down as it hits its enclosure.
Whining Noise from AC Compressor Motor
The compressor motor is a likely suspect when the air conditioner flips on and the noises are usually only heard then. It increases the likelihood it is the in the compressor motor, if there is a noticeable decline in the cooling output as well.
AC Damper Banging Sounds
Another possibility contributing to the bizarre noises is dampers causing the noise. There are some air conditioning systems that have dampers in order to change the amount of airflow reaching different parts of your home. Creating the slamming sounds that might be heard, the damper closing after the AC shuts off.
