Is Your AC Making A Weird Noise? Maybe It’s Time For A Repair

Pinterest LinkedIn Tumblr

Just like any other piece of equipment or hardware, air conditioning units will need repair. And the most obvious way you may be alerted to that is from strange sounds emanating from the unit. These units get very creative with their warning bells, from whistling to clicking, to screeching, and even gurgling. Some may catch you so off guard you may be startled. Hearing any such noise once should be enough to convince you that it’s time for investigation, repair, or replacement.

What Exactly Is Causing The Ruckus?

It’s difficult to pinpoint exactly what part of the unit is affected based on sound. For example, if you hear a banging noise, you might assume that something has come loose. On the other hand, dust and debris are known to cause this result too. A gurgling sound could mean a leaky refrigerant or a blocked draining line. Humming has been attributed to failed condensers but also faulty electrical lines. The point here is to not waste time on trying to decipher what has gone wrong but to speedily contact a professional to see to the matter.

Change Your Filter

This can easily be looked at as the most critical repair. Depending on the type of filter you have installed, it may need to be replaced monthly, every three months, or six months. Fiberglass filters should be changed the most frequently. Furnace filters and pleated air filters can extend up to ninety days without change. Pleated filters that are more on the high end can last up to six months. To find your correct size for replacement head over to where you can also have answered whether the pleated ones are the better option as opposed to the fiberglass and get clarity about which air filter rating is best for you and your household. This is especially important if anyone in the family suffers from a respiratory disease.

How often you use your ac units, the purity of air in your outside surroundings, and the size of your house all count toward the health of your filters. So take extra precaution if you live in a high or even moderately polluted area, and or if your units are constantly running in a home of significant square footage.

Check On The Condenser

You will most likely feel this change before hearing any squealing or grinding sound that might make you think it needs replacing or fixing. Responsible for the cooling aspect of the machine, the moment you start to question if your unit is indeed on, run to a technician. You may also notice your unit changing quickly from one cycle to another. This is another indication of faultiness. Many factors can lead to this failure. A mineral scale build-up, as well as dust accumulation, could be the culprit. This will cause the unit to work harder to cool the room leading to overheating and eventual failure.

An ac repair person will be able to tell you whether a repair is possible or if a replacement is ideal. If the issue is dirt or a broken condenser relay switch, no replacement is necessary as these can be easily repaired. If however there are discovered damaged coils or refrigerant leaks a new condenser most likely will be on the cards. To avoid this end, clean the coils intermittently.

This process is simple. Get your garden hose, point the nozzle at the condenser coils and give a good yet not forceful spray. Angle the hose upward to the top of the coils then downward so that any debris will be washed away.

Your Fan Belt May Be Broken

A high-pitched screeching right when the ac is turned on is a very good sign that something has gone wrong with your fan belt. There are two fans in your unit, evaporator and condenser fans, and maybe unbelievably so, but many issues can arise. Fraying wires may cause short-circuiting and interfere with how the fans work. Belts will be subjected to wear and tear. Extended periods passing without changing them will result in breaks. The motor which powers the fan could have burnt out. Some professionals advise that while this is not a complicated fix per se, it is best not to attempt it yourself especially since the issue could be electrical. To reduce faultiness or rupture, change yearly.

While your unit can give you clues as to what’s wrong, it may also just confuse you. You may be duped into thinking a loud clanging means something dreadful or that a hum couldn’t possibly be dangerous. If you are not a professionally trained ac repair person, for most of the tasks, you may want to take a backseat. Sure, cleaning condenser coils is very doable for the ordinary person but when it comes to potential leaks and electric issues, just sit back and watch.
