10 Air Conditioner Problems You’re Likely to Encounter

As the summer months are quickly approaching, many people start to think about their air conditioner. The best way to keep your home cool is by using an air conditioning unit. However, there are some things you should know before purchasing one, including common aircon problems, that are honestly inevitable with frequent use.

This blog post will cover everything you need to know about how to make sure your AC lasts for years and what common air conditioner problems may arise along the way.

Refrigerant or water leakage

Lines in a system can slowly deteriorate and result in refrigerant leaks. This is one of the less noticed but common air conditioning problems. The pipe’s blockage or failure in drainage systems typically causes flooding or leakage. If the air conditioner is not maintained and serviced regularly, the accumulation of dust and other particles will reduce the efficiency of air conditioners.

If water leakage occurs, it can damage furnishings and electronic appliances in the room. Very low coolant levels can cause severe damage to this compressor, which is an expensive part that should be replaced. A routine check can also detect errors, including possible AC refrigerant leak, and your air conditioner tech can add extra cooling systems when your equipment is not working properly.

Damaged compressor

The compressor is one of the most expensive parts of an air conditioner, so this component should run as infrequently as possible.

If the compressor is faulty, it will not be able to cool down the room sufficiently. This will result in higher electricity bills and an uncomfortable environment as you constantly try to achieve cold air with your air conditioner. A compressor that runs continuously will also shorten the lifespan of your air conditioner. The best recourse is to book for an air conditioning repair when this happens. No one wants to live with air conditioners that only release warm air, especially during summer.

Dirty Air filter

A clogged air filter will reduce the airflow and decrease the efficiency of your air conditioner. It can also lead to overheating and eventual failure of the compressor. Filters should be cleaned or replaced on a regular basis for optimum performance of all air conditioners, regardless of model or type. This way, you will enjoy both clean and cold air.

Moreover, clogged air filters reduce airflow in a centralized environment, consequently reducing air quality in its environment. Poor filters affect cooling systems in fewer ways. Smart thermostats can monitor the filter state and control voltage at the same time. It is even more important for those living with pets to have a professional AC technician check the air conditioner regularly. Dirty air filters may pose some health conditions, too.

You should clean and replace all air filters during summer when the AC mainly uses its power. Intelligent airflow control sends alerts of cleanliness whenever the filter needs cleaning periodically.

Failure of electrical control

An electrical surge could cause electrical damage to your air conditioner. Air conditioners contain electrical components that an electrical surge can damage. This includes the compressor, the blower motor and the control board. If your air conditioner unit experiences an electrical surge, it could cause these components to overload and fail. This damage may be irreparable in some cases, and the air conditioner will need to be replaced. In some lucky cases, you may only need to replace parts like the blower motor, especially if the problem is detected immediately.

Another reason for electric failure in air conditioners is acid buildup. If it can’t be repaired, ask your specialist about your condition. The specialist will recognize acid buildup during tune-up if there’s any electrical malfunction.

Thermostat malfunctions

A defective thermometer could have caused a damping effect causing an uncomfortable cold or a cold spot. Possible culprits in dust and corrosion are dead battery cells accumulating. Looser bolts and wired wires may also negatively influence the operation of the thermostat of your AC unit.

One of the most common problems with air conditioners is a broken thermostat. If your air conditioner isn’t cooling properly, the first thing to check is the thermostat. A broken thermostat can prevent your air conditioner from cooling properly or even turning on at all.

If you think your air conditioner’s thermostat may be broken, you can test it by setting the temperature to its coldest setting and seeing if the air conditioner turns on. If the air conditioner doesn’t turn on, the thermostat is likely broken and needs to be replaced.

AC fan failure

The external system within an electrical system transfers air from outside inside by a fan inside. When this fan fails, the air will not be cooled or heated as it is supposed to be. You can usually tell if your fan is failing if you hear a humming noise when your AC unit is running.

Moreover, compressor components can overheat or exceed protection loading in cooling units. This is most often caused by external damage and may require the replacement of HVAC units. Generally, removal of outer covering will assist with visual inspections. Most of the time, you should contact experts if this problem occurs, as you know the air conditioning units in particular and the resulting problem may cause a delay or malfunction that you don’t understand.

AC making noises

Different sounds indicate separate AC problems; for example, grinding sounds can indicate compressor failure. Whether AC fans are broken or have capacitor problems, they can produce clicking noise. A bubbly noise may be triggered by condensation in the refrigerator. It’s essential that no one neglects the AC noise problems or call your HVAC experts as quickly as possible to deal with them. The technicians who have worked on these devices should help resolve any problems before the problem worsens. An experienced technician is able to explain the sound and solve it. Technicians will give help with fixing a particular problem.

AC running continuously

Normally a central heating unit runs in warmer conditions but periodically turns on. Correcting AC problems can save valuable parts and energy savings while saving energy costs. Aircon systems usually operate on a timer function. If your aircon continues running after the time it was supposed to; this is probably due to a fault in the system.

Another common reason for continuous air conditioner operation is if your thermostat has been manually reset and moved back up to a higher temperature setting. A manual reset of a different setting will cause your AC to run continuously until you change the settings so that they are able to easily meet the desired room temperature. You might also want to have your thermostat sensor checked when this happens.

AC smells bad

The smell in an air conditioning compressor may be because of mould. If your AC unit smells bad, make sure to clean or replace the filters and disinfect the unit. If not done regularly, mould and bacteria can grow within the unit itself. The best way to disinfect an AC is by spraying it with a disinfectant spray that you can find in any supermarket. Then wipe off the excess water using paper towels after 2-3 hours.

Another cause for this problem could be due to dirty filters blocking the airflow, which causes bad odours within the unit to build up. Make sure you change your filter at least once every month or as required by your usage. The drain line might block out if not cleared of dirt and other residues after heavy use over time. Cleaning it should do the trick.
