On a sweltering hot day, it’s blissful to come in from the heat outside and relax in the cool temperature of your air-conditioned home. But, before summer begins, you’ll want to ensure that your AC unit is operating properly. The last thing you want is the air conditioning cutting out during a heat wave and finding local AC services too busy to attend. So, examine these six signs your AC needs to be serviced and head off problems.
1. Not Blowing Any Air
There may be a blockage if you have central AC and cannot feel air coming through the vents. You should check that all the vents are open and that airflow isn’t blocked by furniture or other objects.
If your air conditioning is running, but there’s no air blowing, mechanical failure may be the cause. For example, the blower belt mechanism may have broken, or there could be a fault in the motor. All mechanical repairs should be done by qualified AC technicians.
2. Blowing Hot Instead of Cold
Another strong sign your AC needs servicing is if the equipment blows hot air instead of cold. The hot air can happen for several reasons; a compressor may be damaged, the refrigerant level may be too low, or condenser coils may be dirty and blocked. Condenser coils can be cleaned easily enough, and refrigerant levels topped up without too much effort, but the compressor is different.
The compressor forces the refrigerant through the AC system, moves air, and keeps all the components running. If the compressor stops working, the entire system will come to a halt. Regular preventive maintenance is the best way to stop problems from occurring. Unfortunately, if the compressor has developed a fault, this is likely to be a costly repair or replacement.
3. Leaks are Another Sign Your AC Needs Servicing
Refrigerant is toxic, and leaks are dangerous. Over time, natural wear and tear processes can corrode AC coils, and other components will wear out. Holes, cracks, and loose joints let refrigerant leak out of the system. Leaks will reduce the refrigerant level, and the AC system cannot keep the air temperature at the right level. As a result, a complete system breakdown can occur.
Another source of an AC leak is clogged drain lines. When this happens, moisture cannot drain to the outside, backs up, and will cause a leak inside the home. Rusty or damaged drain pans and broken condensate pumps can also cause leaks inside the house.
4. Nasty Odors from Your AC Are a Good Reason to Call for AC Services
Unpleasant smells produced by your air conditioning system are always a cause for concern. An acrid, burning odor can indicate a serious overheating fault that could lead to a fire and permanent damage. Turn off the system and call for expert assistance straight away as this is a dangerous situation.
The whiff of musty and stale air may point to high dust levels in the system or mold and bacteria growing within the ducts. These nasty particles can detach and blow through the air conditioning system, lowering air quality and causing health issues. A thorough professional inspection and cleaning should be organized as soon as you know of the problem.
5. Wrong Temperature Levels
If indoor temperature levels are too high, low, or uneven throughout the home, there could be several causes. The thermostat may have malfunctioned, air filters may be dirty and clogged, the compressor may be damaged, or a refrigerant leak may have happened.
Changing air filters is easy enough for most homeowners, but fixing refrigerant leaks or the thermostat are tasks for qualified technicians.
6. Loud Noises
Another sign your AC needs servicing is clearly audible noise. Hissing and bubbling sounds can indicate a leak of refrigerant. Banging or clanking noises can happen if a part has come loose. Broken blower belts and faulty blower motors can cause high distinct squealing sounds. A rattling noise often accompanies compressor problems.
A well-maintained and properly operating air conditioner should only make a gentle hum. Any suddenly occurring, distinctive noises can indicate a severe problem is occurring. Switching off the system and booking an immediate service call is best.
