Whenever an air conditioner fails to cool, it can be frustrating and uncomfortable, especially during a hot season. Identifying possible causes for this problem will enable you to correct it quickly. This article by https://www.airconservicing.org/ explains why an air conditioner isn’t cold and offers solutions.
Review the Thermostat Settings
Begin troubleshooting an uncool air conditioning system by checking its thermostat settings. Ensure that the temperature and mode are set correctly. Sometimes, one may inadvertently switch their thermostat to ‘fan’ instead of ‘cool.’ When this happens, no cooling takes place because there is no change in room temperature that triggers AC operation. Besides, ensure your thermostat does not receive direct sunlight or sit near heat-emitting appliances since these conditions affect accuracy.
Examine Air Filters
Unkept air filters often cause air conditioning to malfunction due to reduced efficiency. Blocking occurs when dust particles accumulate on filters, thereby hindering the free flow of air into an AC unit, which then fails to cool properly. You should turn off the unit and remove the front cover to access filters during inspection. Take them out for assessment; if they appear dirty, clean them with a vacuum cleaner or gently wash them with warm, soapy water before rinsing thoroughly and leaving them to dry completely. It’s advisable to clean or replace such components regularly because they significantly improve the performance levels of an AC.
Refrigerant Leaks Detection
The capacity of your AC system to cool may be greatly affected by low levels of refrigerant. With enough refrigerant, it becomes possible for any unit to effectively lower temperatures within surroundings by cooling them down rapidly. One way of knowing whether there are leaks is by observing evaporator coils where ice starts forming due to the absence of gas presence needed. Another sign showing this problem includes hearing a sound like hissing, which implies leakage somewhere along the refrigeration circuit. If suspecting such an issue, call for help from a licensed HVAC contractor from https://www.airconservicing.org/aircon-not-cold/ who will inspect and recharge your system as required.
Clean The Coils
With time, dirt and other debris can accumulate on an aircon’s evaporator or condenser coils, reducing its performance ability. Dirty coils limit the heat exchange, resulting in difficulty in AC cooling down the air inside a room. The first thing should always be switching off and then unplugging such appliances before attempting any maintenance procedure. When cleaning them, gently brush with a soft bristle or apply a coil cleaner solution onto these parts. You must clean them regularly to keep getting the best out of your unit.
Ensure Proper Air Flow
For effective cooling, air must flow in and out of the AC system. This can only happen when all vents are clear from obstructions like furniture. Additionally, ensure no debris interferes with outdoor units, thus keeping away plants or objects that could block free circulation around them.
Analyze the Condensate Drainage
If you want to make your air conditioning unit cool effectively, you must also inspect the condensate drain. This part of an a/c system removes the moisture it collects from the atmosphere. Dirt may clog this pipe when foreign materials accumulate within its confines, blocking it completely. Such action will lead to backing up water into the machine and affecting how well it works. Locate a drain line and remove any obstructions for everything to be okay again.
Examine the Compressor
The compressor acts as a heartbeat for any AC unit; there will be no cooling if this component fails. Some signs that show a compressor is dying include making a strange noise, reduced ability to cool, and frequent on & off cycles, among others. In most cases, fixing problems with compressors requires one to call a professional.
