If you are not an expert, it might be difficult to differentiate between optimal air conditioning performance and any deviation from the norm. In most cases, these anomalies lead to significant issues. Telling whether your air-conditioning unit needs repair is usually not so difficult, but only if you know what to check for. There are signs, which you should always be on the lookout for, and get an HVAC repair company to work on them as soon as you notice them. You should not wait until when the air conditioner stops working altogether. Some of the signs to look for are highlighted below.
Red flags for a defective air conditioning unit
No fresh air
This is probably the most obvious sign to look for. It may get to a point when you feel like your air conditioner simply is not doing what it is supposed to do. This happens even when you try it at full blast. It is an indicator, showing that your air conditioner needs to undergo some repair work. The problem might be as severe as the compressor could be failing or levels of the coolant are getting too low. Getting a professional to work on it should be the immediate step.
If you notice that the amount of air flowing through the AC vents is little or weak, the compressor of the unit might be failing. You may also notice variations of temperatures in different rooms, indicating a problem with the duct. Another common cause of poor airflow is debris being stuck in the vents of the air conditioner, which obstructs airflow as well as poses a health threat. All this are signs that your air conditioner needs to undergo some improvement.
The problem may at times be with the thermostat, and not the conditioning unit itself. If the thermostat cannot control the room temperature, then the function of the entire air conditioner system is compromised. You will be unable to regulate temperatures and thus, not enjoy optimum temperatures. The next move after noticing this problem should be to get it repaired.
Moisture and leakage
Moisture or leakage near or around the air conditioning system indicates some problems. Reasons for that might be either the refrigerant is leaking or the drain tube used to dispose of condensation from the conditioner is broken or blocked. Refrigerant leaking is a major issue as it can be a serious health risk. Getting a professional to do the repair work should be done immediately.
