    You are already familiar with different smells an AC unit can develop. But, there are also noises your air conditioning Mesa AZ unit can start producing. Give it an ear, and see what’s what.

    Banging

    If you ever hear a loud, banging noise coming from your air conditioner Mesa AZ, you can be sure something is either broken or loose.

    It can be anything from a piston pin, connecting rod, or a crankshaft inside the unit’s compressor. Sometimes it means that the indoor blower is out of balance.

    Banging can also indicate the need for the entire compressor to be replaced.

    Clanking

    Clanking also indicates that there are out-of-balance or loose parts inside your AC unit. The compressor may be loose, or inside parts have failed.

    A clanking noise may signal broken outdoor fan blades, or a faulty indoor blower. Never ignore the clanking, as it can only get worse and create bigger issues.

    Clicking

    Clicking sounds can be heard when starting up or shutting down your AC unit. It is normal to hear clicking during those phases.

    However, if there are persistent clicking noises when the AC is running, it might indicate a failing thermostat or defective control switches.

    Since every AC unit contains plenty of electrical parts, pay attention to any untimely clicks, as it is better to quickly remedy or prevent any failures of electrical components.

    Buzzing

    Buzzing noises are among the most common of unwelcome noises your air conditioner can produce. The problems buzzing indicates can mean loose parts, loose outdoor fan, debris in outdoor or indoor unit, loose fan blades, refrigerant leaks, dirty air filter

    Since buzzing can be produces because of many issues, it is best to contact a resident air conditioner Mesa AZ repair experts and let them take it from there.

    Squealing

    Squealing almost exclusively stems from motor issues, whether those are problems with the motor of the indoor blower, or the motor of the outdoor fan.

    What’s more, housing and blower wheel can also squeal if a malfunction is present. There are, however, AC units which produce this noise during regular star-ups. But, you will be able to distinguish regular start-up noises from a newly developed sound.

    Humming

    Humming sounds generally do not point to a serious matter. They do signal something may be off in your AC unit, but usually nothing to worry about.

    Many parts of your unit can vibrate slightly and thus start humming. If the hums are gentle, there is nothing to fret about.

    It is good to have it checked though, as there is always the possibility of humming becoming more prominent, which might mean problems with electrical components.

    Rattling/chattering

    Rattling indicates deterioration of the AC unit and parts becoming loose. It can also mean that the system is clogged by leaves or twigs.

    Chattering sounds are mostly made by electrical contractor in the equipment, which can cause further damage to other components if left unchecked.

    Fans also rattle when loose. You can check for loose bolts or screws in the casing, change the air filter, or clean the condenser coils.

    Screaming

    This is the big one. If you ever hear a high-pitched screaming or whistling coming from your air conditioner, turn it off and immediately call the professionals.

    Refrigerant leak is the most common reason for such a noise, which can not only damage your unit, but can also threaten the health of your family.

    Screaming can also be due to high internal pressure in the compressor, which is extremely dangerous.

    Leaky Air Conditioner? These Might Be the Reasons

      There are many reasons why your air conditioning Scottsdale unit might be leaking, and here’s a list of the most common ones.

      Drain pan is cracked or clogged

      Air conditioning Scottsdale repair professionals list problems with the drain pan as the most frequent reason for a leaking unit.

      As the unit nears the limit of the service life, it is extremely common for the drain pan to become rusted and corroded. Water then freely drains through the pan, making a puddle underneath. Pan replacement fixes the problem easily.

      Sometimes dust, algae, and debris collect in the drain pan, leading to a clogged drain hole. If this is the cause, simply clean the pan and resolve the issue.

      Condensate line is clogged or damaged

      If there are no problems with the pan, the next thing to have inspected is the condensate line. A PVC pipe is what usually makes condensate lines, which back up water when clogged.

      Water starts to collect in the pipe, as well as the drain pan, leading to the inability of the system to drain itself properly. Flushing the pipe resolves the issue promptly.

      Condensate drain pump is faulty

      If your air conditioning Scottsdale unit was installed in the basement, then you have a drain pump. And if it breaks or malfunctions, you are definitely going to have leakages.

      If the drain pump doesn’t work as it should, it will back up the entire draining system. There is no other solution for this problem than to replace it. Always have trained repair experts perform this service.

      The filter is dirty

      As mentioned earlier, a dirty air filter can cause a variety of issues, leaking being one of them. This problem is usually prevented by scheduling regular maintenance.

      A dirty air filter usually leads to frozen evaporator coils. As the coils begin to thaw, they produce excess water which the drain pan simply cannot handle. Water begins to dribble, and you begin to notice.

      Low refrigerant

      Air conditioning unit with low to no refrigerant is the cause of many problems. The biggest of the problems is that the system won’t be as effective as it used to be. That is also the easiest way to spot that you are low on refrigerant.

      Another issue is similar to the one caused by dirty air filters. Lack of refrigerant also causes the evaporator coils to freeze, leading to drain pan overflow and subsequent leaks.

      Outside temperature

      This issue usually occurs towards the end of the cooling season. When the temperatures start to drop, and you continue to run your air conditioning unit, it is possible and frequent for the cooling coils to ice up.

      You can prevent this by not turning on your air conditioner when the temperature drops below 60 degrees Fahrenheit, or by not straining your unit to much during this period.

      Incorrect installation

      Probably not the case, as most professionals have installed so many units it has become second nature to them.

      However, if the crew is new or in training, the leaks may be due to incorrect installation. This might be the reason why your brand new unit is leaking water.
