1. Air Conditioner is not Working

Although it would be an issue throughout the summertime, it’s not a difficult one to resolve. To find the issue, the first stop is the thermostat. Your home’s temperature is checked and regulated by the thermostat. The device will turn off the compressor once the temperature in the room has reached the desired level. Thermostats require batteries to work, and as those batteries are drained, the AC is more likely to turn off. If you’ve determined that this is the issue, then just changing the batteries in your AC should bring it back to life. It is essential to also inspect the circuit breaker. Some cases of being unable to start the AC are so easy to fix; you just need to turn the circuit breaker into the “on” state.

On the other hand, your AC shutting down at an unexpected time may be a symptom of poor performance because of less proper air conditioner maintenance. So if your quick troubleshooting doesn’t fix the problem, you should call a professional AC expert immediately. These kinds of problems of AC unit may be caused by faulty wiring or another major issue. At CoolWind, we are always available to fix any kind of issues related to the air-conditioning system.

2. Leakage in Refrigeration System

Because most refrigerant leaks manifest themselves in coolant lines, it is difficult for homeowners to identify. Brightly coloured spots near the air conditioning unit, on the other hand, are an indication of trouble. While it is normal to observe some condensation outside the air conditioner, excessive wetness may indicate that water is seeping from the unit. The reason for this is because the lines and connections in the air conditioning system deteriorate with time, resulting in refrigerant leakage. Water leaks are frequently caused by clogged drainage pipes and malfunctioning condensate pumps. If a little leak occurs, you must refill the refrigerant and perform a quick repair.

If a major pipe issue develops, the entire network could need to be replaced. While refilling the refrigerant, do not let the refrigerant charge exceed its optimal value, nor go under the minimum. When the refrigerant charge is consistent with the manufacturer’s standards, your AC efficiency stays excellent. If you find that your unit is leaking refrigerant, switch it off immediately and contact our staff for assistance. It is possible that low refrigerant levels can cause severe damage to the compressor, which is one of the most expensive elements to replace.

3. AC is Not Cooling the Room/ Low Cooling Speed

These types of common AC issues can happen in two ways. You may notice that the air conditioner is operating but that no air is flowing out from the ducts. Second, despite the fact that you can feel some air, it does not appear to be particularly cooled. Most of the time, this problem is simple to resolve. Basically, it could be a tripped circuit breaker. The blower belt may potentially be worn and in need of repair, which would explain the problem. Low refrigerant levels might also have a negative impact on cooling.

In addition, if your air conditioner’s airflow is blocked by a dirty air filter, it will not produce cold air. A clogged air filter can cause the condenser unit to freeze up, even more, reducing the cooling capacity of your air conditioner. Changing your air filter on a monthly basis can help your air conditioner produce icy airflow.

4. The Air Conditioner is Turning On and Off Frequently

Short cycling is another term that describes this issue. Instead of having completed a full cooling cycle, the air conditioner turns on and off repeatedly. This is a significant problem that has the potential to damage the compressor. The cause of the problem might be as simple as dirty air filters or incorrectly adjusted thermostats in some cases. It’s also likely that your air conditioning unit is a little too strong for your room.

5. Failure of the AC Fan

The outdoor unit of an air conditioner distributes heat from the inside to the outside with the use of a blower that is positioned in the outdoor unit. If the fan situated outside the home does not function properly, appropriate heat transmission will not occur. As a result, the compressor of the air conditioning system may be overheated or break the safety load. If it causes internal damage to the compressor, the worst-case scenario is that the ac unit will have to be replaced.

The following is the solution for an AC fan failure. There might be a problem with your system’s cabling or a loose component someplace if the blower on your system suddenly stops working. In such situations, just remove the protective cover and physically check the problem. Again, make sure to switch off the electricity before you begin. Although it is possible for you to identify an air conditioner problem in most situations, it is always best to hire a professional such as CoolWind Experts to ensure that the air conditioner is repaired properly.

6. Some Unusual Odours Coming from the AC Unit

A burning smell is one of the signs of an underperforming air conditioner. Some residents also notice smells that they believe are unusual. These odours may be noticeable coming from the vents or when you are in close proximity to the primary air conditioning unit. Electrical smells may indicate that there is a problem with the motor’s wiring. Because of the clogging of your air filters, your system may overheat, resulting in the release of burning odours. Improper drainage is a contributing factor to mildew odours.

If you notice a burning smell, switch off the air conditioning immediately. Check the air filters for clogging. If they appear to be soiled, they should be replaced. Regular cleaning of your home’s air ducts and air conditioning unit is a good strategy to avoid the make and spread of unpleasant and unusual odours.

7. Electric Controls Failure

Frequent on/off cycling of your air conditioner will result in early wear of the fan controls and compressor. The cooling fan motor, the compressor, and the blower motor are connected to initiate the unit. It may be impossible for the motor and compressor to operate if a problem occurs with the connection. It is essential to inspect the electrical contacts to figure out the problem.

8. Evaporator Coil Has Frozen

It is possible that your air conditioner will stop operating as a result of a frozen evaporator coil. When your air conditioner does not receive enough air to work properly, the evaporator coil might become frozen. A frozen evaporator coil can cause your air conditioning system to freeze up and perhaps discontinue running. Sometimes, sheets of ice will begin to build on the coil. Over time, the coil becomes coated in ice, preventing the refrigerant contained within the coil from absorbing latent heat. The smooth operation of the air conditioning is disrupted by this AC issue.

In order to determine the source of the problem, first, examine the damage. Allow the evaporator coil to defrost. Make sure that the power has been turned off first. It generally takes 24 hours for the evaporator coil to completely defrost. Using a hairdryer can support the process to be done quickly.

But be careful not to overheat the coil. In the event of moderate frost, keep your system operating in fan mode since the blower fan will melt away the frost without causing the unit to shut down. It is likely that you will need to contact an HVAC specialist to fix the issue.

9. Strange Noises Are Coming From the Air Conditioning Unit

Take into account that the electrical components of the air conditioning system do generate clicking noises when the air conditioner is turned on and off. But if you hear continuous clicking sounds, it’s possible that your thermostat is about to fail or that your control is malfunctioning. Putting up with electrical system sounds puts your air conditioning system at danger of developing more serious problems in the future.

If the system creates squealing noises, the belt should be checked. Belts can go out of alignment at times, and they can also become worn out. Squealing can also be caused by faulty fan motors, as well as by the blower wheel and its casing failing. Grinding noises are often indicative of a problem with the bearings of an alternating current motor. Pinging and popping might be caused by a piece of loose metal in your ducting. Examine the cover panels for rattling and tighten them as necessary if you see them be loose.

When you hear pounding, examine inside the compressor for a loose or damaged element that might be the source of the problem. When pounding is heard, it is a good idea to plan for a compressor repair in advance.

10. Air Conditioner is Blowing Hot Air

Why does your AC produce hot air rather than cold air? When you are already hot inside the house, there is no reason to get much warmer. Even during the hottest months, this issue may arise. This is a very common problem with AC units. A possible cause your AC may have is a dusty air filter, duct blockage, or debris in the compressor, which may cause it to overheat. The refrigerant levels might potentially be below. In order to reduce blockage risks and maintain system efficiency, you should change air filters on a monthly or bi-monthly basis and arrange for duct cleaning on an annual basis. 

To avoid wasting money on repairing or replacing AC components and creating more work for yourself, have a professional examine your AC units for leaks before you add any refrigerant. Thus, you save money, and cool winds will always blow in your home.
