There are many causes of AC unit failure, including proper installation and regular AC maintenance. However, being negligent about your HVAC system may cause serious problems that could even cause your AC unit to stop working. You need to be aware of some common causes of AC unit failure.
1 – Frozen Evaporator Coils
It’s also important to keep your AC unit itself clean. The coils must be free of dirt and debris for the system to work correctly. If the coils are dirty, they won’t be able to absorb heat as efficiently.
This will lead to your AC unit working harder than it needs to, leading to higher energy bills and decreased lifespan. To clean your coils, you’ll need to use a special cleaning solution made for this purpose.
You can find these at most hardware stores. Once you have the cleaner, follow the instructions on the label.
2 – Dirty Condenser Coils
Sometimes, dust and debris build up on the condenser coils. This forces your HVAC system to work extra hard to fulfill its job – keeping you and your family cool. With so much pressure going on for a long time, your machine will overheat and eventually stop working.
So it’s important to maintain clean coils with a regular tune-up one to two times per year for optimum performance and to avoid potential AC breakdowns.
If you don’t clean the coils, your AC will have to work harder. This can lead to a breakdown of the AC unit. To avoid this, performing a regular tune-up on the AC unit one to two times per year is important. This will ensure that the AC unit runs at peak performance and avoids potential breakdowns.
3 – Low Refrigerant
Each AC unit comes with a refrigerant specification that you should follow. But in reality, sometimes people are overcharging or undercharging it. This affects the performance and efficiency of your AC unit. If this is your problem, hire a professional AC technician who knows exactly how to match the charge with the manufacturer’s specification.
4 – Leaked Refrigerant
Refrigerants can also leak. If this is the case, adding or removing refrigerants will not solve the problem. Instead, your air conditioning technician should find the leaks, fix them all, and test the AC again. This treatment will take quite some time, so you’ll need to be patient to ensure all leaks have been repaired.
5 – Fan Problem
Your AC unit has two kinds of fans. One blows cool air indoors, and one blows the heat out of your house. Many things can cause your AC fan to stop working, such as lack of lubricant and dirt buildup. This problem usually shows early signs such as poor airflow or not-cool-enough air. Ignoring this may lead to more serious issues like a damaged compressor and an air conditioning system breakdown.
If you think your AC fan may not be working properly, it’s important to have a professional take a look at it. Ignoring the problem can cause more severe damage to your air conditioning system, and it may even lead to a breakdown. So don’t wait until it’s too late – call a professional today!
6 – Faulty Circuit Breaker or Fuse
When your air conditioner stops working suddenly or fails to start, please don’t force it by turning it on again right away. Instead, wait for about 15 minutes to let the machine cool down. Then, check your circuit breaker panel or fuse box. Reset your circuit breaker or replace the fuse that connects to your AC. Then try turning your air conditioner on again. If the problem persists, give us a call.
If your air conditioner is still not working after following these steps, please call us, and we will be happy to help you troubleshoot the problem.
7 – Thermostat Problem
A failed thermostat can cause your AC to turn on and off frequently or even not work. You can try to recalibrate or reprogram it. If that doesn’t solve the problem, you may need to replace your thermostat. Another possible thermostat problem is a dislocated sensor, which you can settle by simply readjusting the sensor’s position.
If your AC is still not working correctly after trying to fix the thermostat, the issue may be with the AC unit itself. First, check to see if the unit is getting power and that all the connections are secure. You may need to call a professional for further assistance if everything looks good there.
It can be frustrating when you turn on your air conditioning system, but it just doesn’t work. You may wish for a quick fix, but sometimes DIY methods for fixing your AC problems is not the best approach and can keep you feeling the heat for longer than necessary.
If you are unsure of the cause of your AC failure, it is better to call a professional to settle the issue and resolve it quickly.
