Your aircon is running, but something feels off. It’s not cooling like it used to. One possible culprit? The expansion valve.
This small but crucial part regulates the flow of refrigerant. When it fails, your whole system can suffer. So, how can you tell if it’s the issue?
Common Signs of a Faulty Expansion Valve
Let’s break it down. Here are signs to watch for:
-
Inconsistent cooling – Sometimes it’s cold, other times it’s not.
-
Frost build-up – Ice on the evaporator coil or refrigerant lines.
-
Hissing sounds – Unusual noises from the aircon unit.
-
High electricity bills – Your unit works harder but delivers less.
If you notice these symptoms, your expansion valve might be struggling to do its job.
What Causes the Problem?
Several things can lead to expansion valve issues:
-
Dirt and debris blocking the valve
-
Wear and tear over time
-
Incorrect refrigerant charge or system pressure
Therefore, routine maintenance is key to avoiding these headaches.
What Should You Do Next?
First of all, don’t ignore the problem.
The longer you wait, the more strain you put on your aircon.
Instead, call in professionals who can diagnose the issue and fix it right away.
