All electric appliances, including air conditioners, require routine maintenance. This enables you to identify potential issues before they result in expensive future repairs. Being proactive in this area also means a longer typical lifespan of your units. It’s crucial to learn about the common air conditioning problems so that you can take preventive measures to avoid huge repairs.
Here, we will discuss a few common AC issues and how to deal with them effectively.
AC is not turning On
If your AC isn’t working or turning on, you need to check the batteries in your thermostat. Replace it if the batteries are dead. To determine whether the cooling mode is active, check the thermostat settings. Moreover, confirm that the batteries are in good condition and that the necessary temperature settings are present.
Check the circuit breaker to see if your thermostat is on and if the air conditioning is still off. If the circuit breaker trips, you won’t be able to use your air conditioner. Turning the switch on and off is necessary to reset the circuit breaker. There are reliable AC Repair Services in UAE to help you out.
AC not blowing Cold Air
Your air conditioner won’t blow cold air if a filthy air filter stops it from moving air. If your air filter is dirty, the condenser unit may freeze and lose cooling capacity. Change your air filter every month; it will help your air conditioner blow out cold air.
Air Conditioner Freezing up
Low outside temperatures and little ventilation can cause your air conditioner to freeze. Blower motor issues and low coolant levels could also occur.
Water Leak (Indoors)
Your interior air conditioner needs maintenance if you notice water escaping from it! Sometimes, a clogged drain in an air conditioner may cause water leaks from the appliance.
There might be the growth of algae or fungi. Another reason for this AC issue could be that your condensate pump must be replaced.
A water leak is one of the most frequent issues with air conditioners, which may be rectified by a technician or even at home using a do-it-yourself method. A wet and dry vacuum can clear the clogged condensate pipe. Put 6 ounces of vinegar into the drainpipe to eliminate fungal or algae build-up. Read the user manual to confirm the exact placement of the drainpipe.
Water Leak (Outdoors)
You might see a pool of water under your air conditioner’s compressor on sweltering summer days.
Potential causes include a dry air filter, damaged condensate pans, a defective AC seal, poor installation, etc.
You should detach the power supply from your air conditioner and switch it off after identifying the problem. If this issue is resolved immediately, things may become simple. You should contact a professional for this air conditioner issue.
Ac Refrigerant Leak
Your air conditioner’s coolant will begin to leak, causing temperature fluctuations and improper functioning. Refrigerant leaks can result in low efficiency and high-power consumption—coil freezing because of a damaged compressor.
If there is uneven cooling, inspect your air conditioner regularly for any refrigerant leaks.
Air Conditioner Making Noises
Depending on the nature of the issue, an air conditioner might make various noises. Your air conditioner may be making a variety of noises for several reasons. A refrigerant leak may produce a hissing sound.
If your AC makes clicking noises when you turn it on and off, there could be a relay issue. Noises like thumps, rattling, or banging indicate a malfunctioning blower or motor component.
Damaged Compressor
The compressor, which helps refrigerants conduct heat exchange and control the AC pressure, is one of the essential AC parts. Dirty coils, changes in refrigerant levels, and a lack of lubrication can cause failure of the AC compressor.
A shortage of refrigerant will cause the compressor to overheat and stop operating. If more than necessary, the extra refrigerant will raise the pressure inside the appliance, which may also lead to failure.
If your air conditioner is not cooling adequately or detects a poor HVAC airflow, a compressor problem will likely be at fault. Contact a local air conditioning expert to resolve this common AC issue.
Frozen Evaporator Coil
The evaporator coil freezes when your air conditioner doesn’t have enough air to operate. Blocked vents and ducts, unclean filters, or a broken fan can bring on insufficient airflow in the system. An air filter should be in good condition to maximize airflow and interior quality.
Electric Control Failure
If you often turn your air conditioner on and off, the compressor and fan controls may deteriorate. Electrical connections are made between the compressor, blower, and condenser fan motor to turn on the device. It is possible for a connection issue to prevent the compressor and motor from starting. You should check the electrical connections to find the problem.
Capacitor Failure
Occasionally, a clicking sound when your air conditioner turns on and off abruptly indicates a capacitor problem. Your air conditioner’s capacitor is a crucial component because it provides the motor with a kickstart so it can begin operating.
When your AC has to work hard in the intense summer heat, the capacitor may overheat. Moreover, your capacitor can be damaged by frequent temperature changes and power fluctuations.
Contact a specialist to get your capacitor examined. Since there is a chance of receiving an electric shock, you cannot fix or replace it yourself.
Drainage Problem
Furthermore, dust, algae, and debris can block the drainpipes. Moreover, pollutants and problems like unpleasant odors may arise. Ensure your drain line is regularly maintained, cleaned, and inspected to prevent this. Air conditioners that are not mounted level may not drain properly.
Sensor Problem
A thermostat sensor is included in the air conditioner and placed close to the evaporator coil. The thermostat adjusts the cooling process based on the outside temperature and keeps track of the air temperature in the evaporating coil. The air conditioner may randomly turn on and off or cycle constantly if the sensor is pushed out of place. The sensor and evaporator coil shouldn’t be near one another. By bending the wire and holding the sensor in place, you can adjust it.
Complex devices like air conditioning systems need routine care and maintenance.
Here are a few simple AC Maintenance Tips you need to follow.
- Change Your Filters
- Fix AC Leaks
- Insulate to Keep the Air Cool
- Perform Annual AC Maintenance
- Upgrade for Efficiency
Frequent maintenance helps keep an AC unit functioning well and guard against future problems. With the help of the above instructions, you’ll be well-equipped to address the most common AC issues quickly. You should maintain your AC system professionally at least once a year to avoid issues.
Frequently Asked Questions
Why is my air conditioner not cooling effectively?
There could be several reasons for this problem, such as a dirty air filter, refrigerant leakage, or a malfunctioning compressor.
Contact a technician to diagnose and sort out the issue.
What causes strange noises coming from my AC unit?
Unusual noises like grinding, rattling, or squealing could indicate a loose part, damaged fan blades, or issues within the motor.
What should I do if my AC constantly turns on and off?
This frequent cycling, known as short cycling, might occur due to an oversized AC unit, a malfunctioning thermostat, or restricted airflow. Check if your thermostat is proper and the air filter is clean.
Can I fix the refrigerant leakage on my own?
Refrigerant leakage requires professional attention. Refrigerants harm the environment and handling them without proper equipment and training can be dangerous.
