When you turn on your air conditioner and it does not turn on, it is quite unpleasant and it means that there is some issue with the air conditioner. Even the best quality air conditioners can have issues. Every machine has advantages and disadvantages.

Calling the professionals every time you face an issue is not a solution. You should be confident enough to fix your air conditioner yourself. In this article, you will get information about how to fix your air conditioner.

There are several types of air conditioners available, including central, mini-split ductless, and heat pump.Whatever type you have in your home, this article will teach you how to maintain it and why your air conditioner isn’t working.If your air conditioner is not working, then before calling an expert, you should check a few things, such as checking your tripped circuit breaker, checking your air conditioner filter, dirty coils, checking the condensate pump, and much more.

Tripped circuit breaker:

When the air conditioner is on, you must be extremely cautious with the electronics. If you are using a microwave oven, doing laundry, using a dishwasher, and using an air conditioner all at once, there are chances that the power surge may cause a breaker to trip.

If the circuit is overloaded, then it will trip the circuit breaker. So, to get rid of this issue, you don’t need to call an HVAC professional. All you have to do is to open the power supply cap and change or reset the breaker.

All the switches on the panel are labeled. You should find the switch that corresponds to your air conditioner. The switch will have three options: ON, OFF, and neutral. Set the settings to neutral before switching it back on.

Dirty air filters and AC coils:

Air filters in air conditioners are the most essential parts of the air conditioner. You need to clean the air filter once a week or regularly. There are two types of filters: one is replaceable and the other is disposable.

Air filters absorb the heat from your room. For air filters to work smoothly, you need to change them. To replace the air filters, take a tub and fill it with water. Air filters are located behind the grills.

Take the grill off and take out the filter. Soak the filter in the tub that is filled with water. Make sure that each edge of the filter is completely soaked in the water. After that, take out the filter from the water and wait for the filter to dry down.

You can also dry the filter using a clean cloth and napkin and place it back in its place carefully. The main purpose of the air filter is to absorb heat as the moisture condenses and drips into the drip pan. If the filter is blocked with dirt, it will block the airflow. As a result, the moisture will not drip into the drip pan it will freeze on the air conditioner coils.

So, if you see ice on the AC coils, you should immediately turn off your air conditioner, remove the cover of the air conditioner, and use the blow dryer to melt the ice faster. After it is melted, wait for it to dry, and then turn the power on.

Broken Thermostat:

One of the easiest things to check is your thermostat’s reading. If the thermostat reading does not match the temperature that you set, then it means that the thermostat is broken.

Or if your air conditioner is not cooling your room in the summer, then check the thermostat. If the reading on the thermostat is higher than the outside temperature, then it is broken. Or if the thermostat is set incorrectly, your air conditioner will not provide useful work.

Thermostat models require batteries. If the battery of the thermostat is dead, it will not work properly. If this is the case, you should change the batteries in the thermostat as soon as possible if you notice any problems.If your thermostat screen is blank, there could be a variety of problems, including dirt inside the thermostat cover, wiring issues, and much more.You can change your thermostat. It is inexpensive.

Failure in the Capacitor:

A capacitor is not a device that will run forever. There can be a lot of issues with the capacitor, and you have to change it from time to time. Capacitors play an important role in the air conditioner.

Capacitors send energy to the fan motor and power the unit when energy is needed. Capacitors are very small devices but play an important part in cooling your rooms. The majority of air conditioners have a lifespan of 10 to 15 years.

If your air conditioner is older than that, then you have to change your air conditioner. But before you replace it, you should test your capacitor. You can test your capacitor with your multimeter.

Failure of the condensate pump and condensate line

If your air conditioner is not providing the best performance and not cooling your room, then there must be a problem with the condenser coils. If the coils are filled with dust balls and other elements, they will not provide useful work. The main purpose of the condensate pump is to dissipate heat outside during the cooling process.

The more efficiently condenser coils dissipate heat, the more efficiently it will cool your rooms. If the condenser coils get dirty, it can cause the system to overheat and the entire system will shut down. To clean the condenser coils, you should use a vacuum or spray bottle filled with water and detergent. Use the vacuum to remove the dust covering the condenser coils.

Water comes out of your house through a condensate line. If the line is blocked with some element, It can become clogged and cause the air conditioner to malfunction. To get rid of this problem, you should open the cap from the top and slowly pour one cup of vinegar into it. Wait for half an hour and then flush it with water.

Extremely High Temperature:

It is common sense that if the temperature outside is high, the air conditioner will not provide useful work. The air conditioner usually cools your home by 20–30 degrees. But at some point, your air conditioner will not sufficiently remove the humidity and will not cool your room.

The air conditioner will not work efficiently if the weather outside is above 100 degrees Fahrenheit. When the temperature outside is high, the air conditioner will force itself to provide you with good performance.

So don’t even try to open up your air conditioner because there is no fault with it. But still, if you are not satisfied, then you can consult with the professional and increase the thermostat’s temperature.

Undersized vs. oversized Air Conditioner:

If you have an air conditioner that is too big or too small for your room, it will not work. If your air conditioner is too small for your room, it will struggle to cool your room. When the air conditioner applies more power, it will not last long.

And if your room is small and the air conditioner is too big, it will not run smoothly. When you turn on your air conditioner, it will cool the room quickly, reduce the temperature of the room, and shut down.

And it will repeat this process again and again. When the cycle continues, the constant switching on and off process will reduce your home’s energy efficiency. So, before you purchase the air conditioner for your home and office, you should first measure the diameter and size of the room and place it in the place where it will run smoothly.

Fuse blow:

Your air conditioner can also stop working if the fuse is damaged. So, before you open your air conditioner and put a lot of effort into it, you should first check the fuse and other wiring.

The main reason a fuse blows is if too much electrical current goes through the wires. If the fuse is damaged, it will cause the condenser to stop running. The fuse box is a small square box outside your house. You can open it and check the fuse by using a multimeter. If the fuse is not working, you can replace it with a new one.

Refrigerant leak:

If there is an issue with the refrigerant, then it will cause serious issues. Refrigerant is the gas that cools down the hot air and provides you with cold air to keep your room cool and cozy.

But if the refrigerant gas leaks, it will smell bad and can be poisonous. If there is an issue with the air conditioner, then you can see the condenser unit. If there is any frost on the coils, then it is more likely to leak.

Other than that, if your conditioner is not providing cool air while it is turned on, then there will be an issue with the refrigerant. You can call professionals to cope with this issue.

The air conditioner needs to be replaced:

If your air conditioner has been running for 15 to 20 years and suddenly stops working, then you should call a professional to see what the issue is. Although most air conditioners last only 10 to 15 years, if yours is still working after that time, you are extremely fortunate.If you turn on your air conditioner and it is not working, then I would prefer to replace your old air conditioner with a new one rather than spend a lot of money on it.
