It is crucial for us to have a properly functioning air conditioning system to handle hot summer days. At the same time, your furnace should work properly before the winter comes.
However, numerous issues can happen throughout the heating or cooling seasons, which will affect your comfort levels and convenience.
Of course, the problems can happen throughout the season, which will require you to find a professional repair service to help you deal with an emergency.
The best way to understand the importance of regular duct cleaning is by checking here for more information.
On the other hand, if you have some knowledge about electricity, you will be able to do it yourself. We are not saying that you should deal with severe repairs, but you can assess some issues without calling professionals.
It is vital to learn about tips to prevent potential issues and repair the current one.
We will present you with the most common issues that may happen to your cooling system and tricks that you can do to handle them along the way.
However, if you are not confident that you can do it, we recommend avoiding doing it yourself and finding a professional company to help you.
Understand the Central Home AC Unit
The first thing you should remember is that the central AC system features two essential components: the evaporator coil and the condensing unit, which is outside the house.
The refrigerant from the evaporator coil will pick the heat from your household and move it into the condensing unit.
A fan within the condensing unit will blow the air outside and remove heat from your household.
The condensing unit features three parts that you can replace by yourself:
- Start/Run Capacitor
- AC contactor
- Condenser fan motor
Simultaneously, the condensing unit features a compressor, but that is not something you can replace without professional help.
AC Has Stopped Cooling
When you notice the changes in cooling, the first thing that you should do is checking the thermostat to determine whether you accidentally changed settings. In case the furnace starts to work, it means that you do not have a problem with it.
In case the fan is not working, you should reset the circuit breaker within the furnace. Finally, if that will not turn it on, you should call a professional.
Apart from the thermostat, you should check out the outside unit and determine whether the compressor works. Remember that compressor sounds like a refrigerator, so it means that it operates if you hear the noise.

On the other hand, you should follow these tips:
If you have noticed that your AC unit is not operating correctly or does not get plenty of cool air during the summer days, you should check out these things.
It would be best if you made sure that the furnace filter is spotless. At the same time, you should go to the condenser unit and clean the coils.
If the filter clogs, that may reduce the airflow, which will lead to freezing of the evaporator coil. Therefore, you will not be able to cool your household as a result.
In case you wish to change the filter, you should open all registers and do it properly. However, if that is not causing any change, you should check out the thermostat and switch from cooling to off while the fan should be on auto.
Let it run for half an hour, and check out the airflow throughout the process. Then you should turn it back on to cooling mode and test it. If it operates correctly in the next twelve hours, it means that you have solved a problem.
Therefore, fixing a cooling unit is not as simple as it gets, but you will be able to do it by following the tips we’ve mentioned above.
On the other hand, if the condenser coils are clogged, the compressor can quickly shut down due to overheating. You will experience minimal cooling, which will stop as time goes by.
Make sure that you clean them properly. You need to turn off the power and flip the furnace and AC circuit breakers on the main electrical panels. You should turn off the power switch on your air handler and furnace.
Then you should move the disconnect block and clean the coils. If you do it, and the unit is still not working, it means that you have another problem at your hands.
Replace On/Off Capacitors
Most AC units come with at least a single capacitor that stores electricity and releases it so that the condenser fan and compressor could start operating. Simultaneously, capacitors will protect the unit from voltage fluctuations, which means that you will use the unit for years.
Of course, they tend to degrade, which means that they will provide you less power as time goes by. Even though gradual failure is unnoticeable, it may affect other components including the motor, if it stops completely.
By clicking here, you can enter the site that will explain to you how to maintain the HVAC system with ease.
Since they are as cheap as they can get, we recommend you to be proactive and to replace them at least once in five years.
Of course, you should discharge the capacitors before disconnecting it from the bracket, which is an essential consideration you should remember.
Final Word
It is vital to remember that DIY repair of your air conditioning unit is not as simple as it seems in this particular article. That is the main reason why you should find a professional help in case you’re not confident enough to handle everything by yourself.
That way, you will spend more money in a short run, but you will get fixed AC as well as warranty deal so that you can protect your investment in the next period.
It is important to understand that whatever you choose to do, having a regular inspection is crucial for reducing the overall expenses in the long run.
