The summer heat may be descending upon Canada, and you might be thinking of turning on your air conditioners. The use of air conditioners has become more common than ever due to the latest energy-efficient technology that makes it possible for you to enjoy your summers in an air conditioned home while not worrying about higher energy bills.
However, any problem with your air conditioner can be a big headache for you. Until a few years back, air conditioners were pretty noisy, however, thanks to the latest technology, they are quieter than ever now. Noisy air conditioners are disturbing, especially when you are trying to sleep after a long tiring day.
High-efficiency air conditioning units come with advanced sound damping technology that keeps the noise level below 55 decibels. However, sometimes your air conditioner may produce an exceptionally loud noise that you should take notice of.
There are different types of sounds and noises which your air conditioner can make. This blog post mentions all the sounds and reasons why your air conditioner might be causing noise and what you can do about it.
Banging Noises
Banging noises are a common indicator of a problem with the compressor. The compressor is designed to provide refrigerant to various parts of your AC system and remove excess heat from your home. However, with time, certain parts can become loose inside the compressor, which might cause a banging noise.
This banging noise is actually caused by those detached components that might be hitting against the exterior framing of the compressor. A professional HVAC contractor with years of experience might be able to resolve this compressor issue. However, most of the time, it might not be easy to disassemble your AC compressor, and you may need to invest in a new air conditioner. But you can always call your HVAC contractor and ask them if they can solve your issue.
Clanking Noises
This one is another sign of a loose or out-of-balance part of an AC. It might indicate a problem with the compressor, or there might be a loose part inside the indoor unit of the AC. Clanking noises could also mean that there is a problem with the indoor blower or outdoor fan, or maybe its blades are out of balance. Such issues must be solved by a professional HVAC contractor before they turn into a bigger problem.
Hissing Sounds
Hissing sounds might not be as common as other types of banging or clanking noises, but they might be a signal of an air duct leak in your house. It might be due to a malfunctioning expansion valve or an air filter that is not compatible with your system.
Whistling Noise
If you are hearing a whistling sound in the middle of the night don’t worry, your house is not haunted, it is just your HVAC system that needs help. Such noises are caused due to a refrigerant leak which damages your air conditioner and can also affect your family’s health. It might also be due to high internal pressures on your compressor. So don’t panic, just call your HVAC contractor to come and repair your AC.
Whirring Noise
A whirring noise is a sound like a helicopter which might be because of a mechanical problem with your AC’s indoor unit or outdoor unit. It might be the result of bad bearings in the indoor unit or a faulty fan in the outdoor unit. Moreover, when the blades of the fan start to become loose, they cause such noises. What you can do is ask your HVAC contractor to replace your blades to reduce the noise instead of replacing the whole unit.
Final Words
Investigating the weird noises coming out of your air conditioner is necessary to avoid any problem turning into a bigger one. Your professional HVAC contractor will fix any issue there might be with your AC that you are unable to detect. You just need to make sure that you have found a professional HVAC contractor who knows how to do their job.
