Nothing gives a homeowner more anxiety than realizing their air conditioning system is not working as efficiently as it should. Unfortunately, people like ignoring the minor issues, and eventually, they become the reason why the system completely breaks down. You should learn all the parts of the air conditioner, and how they function. It would help if you also learned to differentiate between minor and severe issues. Here are four signs of major AC trouble that may need professional air conditioning repair.
The Unit Is No Longer Quiet
A new and efficient air conditioning system operates with a soft humming sound that never interrupts your other activities. However, you should call the technician when your unit starts running noisily. Different noises typically signify trouble with different parts of the system. Rattling, banging, and thumping noises usually indicate that the ductwork is not doing well or has become loose. Sometimes the thumping noises come from the condenser unit when a mechanical part loosens. Buzzing points to an electrical problem with the system, while hissing indicates that the refrigerant is leaking. Grinding usually shows that the compressor is breaking down. Finally, high-pitched squealing comes from a damaged compressor. A technician should check all these noises.
Your air conditioner should provide you with clean and fresh air throughout its lifespan. It achieves the purpose when the air filters are clean and don't have things rotting inside the vents. However, sometimes poor maintenance leads to the accumulation of dirt on the filters. Sometimes, mold grows inside the unit, leading to mustiness inside the house. You should call the technician to assess your system and determine whether it needs cleaning. They will also repair the part causing moisture retention, which will rectify the odor problem.
A functional air conditioner runs through long on and off cycles. It will run continuously while bringing the temperature down to the set standard on the thermometer and then go off when it achieves the condition. However, if yours keeps having short cycles between the on and off state, you should call a technician to assess it. They will check factors like the thermostat settings. By rectifying the issue with the thermostat, they will stop the compressor from turning itself off before the house gets the desired temperature.
You should call a technician immediately you notice any of the mentioned signs of trouble with the unit. They will help you troubleshoot and fix any issues before they ruin your AC.Share
