6 Common Causes of Breakdowns in Daikin Air Conditioners

Air Conditioners

Air conditioning is necessary for any home to maintain a comfortable temperature. Otherwise, your home will have an uneven temperature, which can sometimes cause health problems and mould and mildew growth. For this reason, homeowners go the extra mile to ensure they get the best air conditioner. There are many brands to choose from, but few are on par with Daikin.

Daikin is a Japanese company that manufactures air conditioners and other HVAC products. The company has been in business since 1924 and has a long history of innovation and quality, and the brand’s air conditioners are some of the most popular on the market. However, Daikin air conditioners are not without their faults because they can still experience problems caused by several factors. These include:

#1 – Not Starting

One of the most common problems with Daikin air conditioners is that they won’t start. This is usually caused by a problem with the power supply or the control board, so you’ll need to check these components first. Sometimes, the problem is caused by a faulty capacitor or relay, so you’ll also need to check these components.

However, it’s also possible that the air conditioner isn’t starting because it’s not getting enough power. This can be caused by a tripped circuit breaker or a blown fuse, so you’ll also need to check these things.

#2 – Not Turning Off

When an air conditioner doesn’t turn off, it can be a sign that there is a problem with the air conditioner’s compressor. This is a significant component of the air conditioner, and if it’s not working correctly, the air conditioner won’t be able to cool your home properly.

If the compressor isn’t working correctly, it’s usually because it’s overheating. This can be caused by various things, such as a dirty air filter, low refrigerant levels, or a problem with the air conditioner’s coils.

#3 – Water Leak

Leaking water isn’t unheard of in air conditioners, but you must double-check it because it could also be a sign of another issue. For one, water leaks are commonly caused by condensation. So, if you see a small puddle of water around your air conditioner, it’s probably nothing to worry about.

However, if the leak is bigger or you see water dripping from the air conditioner, it’s a good idea to call a technician. This could signify a refrigerant leak, a serious issue that needs to be fixed immediately.

#4 – Insufficient Cooling or Heating

This is perhaps one of the most common issues people have with their air conditioners. If your air conditioner is having trouble cooling your home or if you notice that it isn’t heating your home as efficiently as it used to, then it’s a good idea to call a technician. This could signify low refrigerant levels, a severe problem that needs to be fixed.

#5 – Strange Noises

Strange noises from an air conditioner are hard to decipher because they can mean many things. If you hear a hissing noise, it could be a sign of a refrigerant leak. If you hear a grinding noise, it could be a sign that the motor or blower fan is having trouble. A technician should investigate any strange noises coming from your air conditioner.

#6 – Refrigerant Leak

Water leaks are one thing, but a refrigerant leak is something else. If your air conditioner leaks refrigerant, it’s a sure sign that something is wrong. Not only is this a problem for your AC unit, but it can also be dangerous. A refrigerant leak can cause respiratory problems and other health issues. If you think your AC unit is leaking refrigerant, call a technician right away.

Hiring an Air Conditioning Technician

When hiring an air conditioning technician, you must consider certain factors such as experience and cost. Experience is always good for any technician, but it’s vital for your air conditioner. You want to ensure you hire someone who knows what they’re doing and can fix your problem quickly and efficiently.

Of course, cost also matters because you don’t want to overspend on a repair that could have been easily fixed. Make sure you get a few estimates before deciding to ensure you get the best deal.


Many typical air conditioning problems can be easily fixed. However, some issues require the help of a professional. If you’re having any problems listed above, it’s best to call a technician for help.
