Your air conditioning unit is an essential part of your heating, ventilation, and air conditioning or HVAC system. During summer, the temperature can spike high. And if your air conditioner or AC isn’t functioning properly, you will compromise your family’s comfort, and so will your energy bills. So, what are the tell-tale signs that your AC needs repair?
In this article, you’ll learn the important signs to watch out for and that would warrant air conditioning tune up.
1. Inconsistent Air Temperature
Your AC should provide a consistent air temperature based on the setting you’ve selected. When certain parts of the room become cold zones while others don’t get any cool air, it could mean a failing air conditioning unit.
If your AC isn’t cooling like it used to be, even after replacing the air filter and cleaning it, then you’ll need the help of a professional such as DM Select Services Alexandria.
Here are the possible causes of inconsistent air temperature produced by your AC:
- Low Refrigerant Levels: Refrigerant or freon is a chemical compound present in air conditioner that absorbs environmental heat, providing cool air when it passes through AC compressors and evaporators. It’s best to consult a professional when adding refrigerant, because using the wrong one poses damage to your AC.
- Worn Out Evaporator Coil: The evaporator coil in an AC system absorbs the heat from indoor air. This AC component is either attached to the furnace or situated inside the air handler. Evaporator coil works with the condenser coil to carry out the heat exchange process, producing cool air. If the evaporator coil is worn out, then your AC produces inconsistent temperature.
2. Burnt Smell When Your AC Is Running
A dirty or clogged AC air filter can restrict the airflow to the essential components of your air conditioning unit, such as the blower motor. The blower motor needs to work longer because of less air coming just to cool the room. Because of exerting too much stress on the AC motor, your system may overheat, producing a burnt smell.
If you smell smoke, then there could be a spark or fire somewhere, which means your air conditioner system recirculates the smoke. That’s why it’s important to contact an emergency HVAC specialist to address this issue right away. Turn off your AC, and don’t use it until it’s checked by a professional.
3. Disturbing Sounds Produced By Your AC
A loud buzzing noise coming from the air conditioner unit is an indication your system is malfunctioning. The odd noises could be due to loose parts, damaged or missing isolation feet, a malfunctioning compressor, or refrigerant leaks.
An air conditioner system has different parts that work together, keeping a room or your entire home cool especially during summer. So, if one AC component becomes loose, the other parts will experience stress and wear out, producing a buzzing sound. If this happens, your AC needs repair.
4. Electrical Control Failure
Frequently turning on and off the air conditioning unit can result in worn out compressor and fan controls. The compressor, the blower motor, and the condenser fan motor make an electrical connection to turn on the AC unit.
However, a connection problem prevents the compressor and motor from turning on. It’s important to check the electrical connections to identify the issue. If you don’t have the background and skill in handling electrical problems, you should entrust this job in the hands of an HVAC expert.
5. Freezing AC Unit
The coils of your AC need periodic cleaning for proper heat absorption. Otherwise, the evaporator coils just freeze all over. In addition, your AC coils may freeze because of insufficient air flow, low coolant levels, and low outside temperature. It can be a problem with stuck blower motor or contraption, too.
If you have frozen evaporator coils, you need to turn off your air conditioning system at the breaker box or mains source. While you’re inspecting the possible cause and fixing the issue, the coils defrost. Contact a professional HVAC immediately when the problem is difficult for you to handle, because a freezing AC won’t work properly until the source is addressed.
You’ve learned the warning signs when your air conditioning unit needs repair. Don’t allow minor problems to become worse. If you lack time or the necessary skills to repair your AC, contact a professional HVAC specialist to do the job. Always remember that a good running HVAC system contributes to your overall home comfort, good health, and happiness.
