An air conditioner (AC) won’t cool your home effectively if it runs without refrigerant, also commonly referred to as “gas” in this context. Here’s What happens if an AC runs without gas or depleted refrigerant:
Reduced Cooling Capacity:
- The primary function of refrigerant is to absorb heat from inside your home and transfer it outdoors.
- Without enough refrigerant circulating through the system, the AC’s ability to absorb heat is significantly reduced.
- This results in less cool air being produced, and your home won’t feel comfortable despite the AC running.
Compressor Damage:
- The compressor is the heart of the AC system, responsible for compressing the refrigerant to create pressure and facilitate heat transfer.
- When refrigerant levels are low, the compressor has to work harder to circulate the remaining refrigerant.
- This extra strain can lead to the compressor overheating and potentially causing permanent damage. In some cases, a damaged compressor might require a complete replacement, which can be a costly repair.
Frozen Coils:
- In some instances of low refrigerant, the remaining refrigerant can become too cold in the evaporator coil (indoor coil) due to insufficient volume.
- This can cause moisture from the air to freeze on the coil, creating a blockage and further reducing airflow and cooling efficiency.
Warning Signs of Low Refrigerant:
- Ineffective cooling: If your AC is running but not adequately cooling your home, it could be a sign of low refrigerant.
- Hissing sounds: A hissing noise coming from the AC unit might indicate a refrigerant leak.
- Icing on the evaporator coil: Visible ice buildup on the indoor coil can be a sign of low refrigerant and a frozen coil.
Important Note:
It’s important to avoid operating an AC for extended periods with low refrigerant. The potential damage to the compressor and the AC system itself can outweigh the cost of having a qualified technician diagnose the problem and recharge the refrigerant if necessary.
