AC Not Cooling or Water Leakage Repair | The Mistry

25 Dec 2025

Facing AC cooling issues or water leakage? The Mistry offers expert AC servicing, gas refill, and repairs for efficient, long-lasting cooling.


As temperatures rise across India, air conditioners work overtime to keep homes cool and comfortable. During peak summer, even the best AC units face performance issues like weak cooling, unusual noise, or water leaking from the indoor unit. These problems not only reduce comfort but also increase electricity consumption and long-term repair costs. Understanding why your AC stops cooling or starts leaking can help prevent bigger issues—while choosing the right technician ensures a safe and reliable repair. This is where The Mistry provides fast, expert, and dependable AC servicing.

AC problems usually start small but become major if ignored. Here’s a complete, SEO-friendly, human-written explanation of common AC issues, prevention tips, and when to call The Mistry for professional service.



Common Reasons Why AC Stops Cooling

Your AC may run continuously but fail to cool the room properly. Several factors contribute to this, especially during extreme heat.


1. Dirty or Clogged Filters

Over time, dust and pollution collect on the AC filters, blocking airflow. When filters get clogged, the AC has to work harder, resulting in low cooling, high energy usage, and sometimes even freezing of the coils. Dirty filters are the number one cause of weak AC performance.


2. Low Gas or Refrigerant Levels

Refrigerant gas is essential for cooling. If the gas level drops due to leakage or long-term usage, the AC cannot cool effectively. Signs include warm air, long running time, and ice forming on copper pipes. Only trained technicians can refill gas safely and detect leakage.


3. Blocked or Damaged Condenser Coils

Outdoor condenser coils release the heat absorbed from your room. When they get covered with dirt, leaves, or pollution, your AC loses efficiency. This leads to slow cooling and higher electricity bills.


4. Faulty Compressor

The compressor is the heart of the AC system. If it becomes weak or stops working, cooling will drop drastically. This is a serious issue and requires expert diagnosis.


5. Incorrect Thermostat Settings

Sometimes the problem is simple—wrong mode or temperature settings. Ensure the AC is set to Cool Mode (snowflake icon) with a temperature between 23°C–26°C.



Why ACs Leak Water

Water leakage from the indoor unit is another common problem, especially during summer or monsoon.

1. Blocked Drainage Pipeline

The AC produces water during cooling, which should drain through a pipe. When this pipe is blocked by dirt, algae, or dust, the water flows backward and drips inside the room.


2. Frozen Evaporator Coil

If the coil freezes due to low gas or weak airflow, the ice melts and leads to excess water dripping.


3. Improper AC Installation

If the indoor unit is not installed with proper tilt or alignment, water does not drain correctly and may leak.


4. Loose or Damaged Drain Tray

A cracked or loose drain tray cannot hold the water, causing leakage.



Homeowner Tips to Maintain AC Performance

Regular maintenance prevents most AC issues and keeps your unit performing efficiently.

1. Clean Filters Every 30 Days

Remove the filters, wash them gently under running water, let them dry, and reinstall. This simple habit improves cooling and reduces energy consumption.


2. Turn Off AC During Thunderstorms

Lightning and power fluctuations can damage the AC compressor or PCB. Switching off during storms protects your unit.


3. Keep the Outdoor Unit Clean

Ensure the outdoor unit is not blocked by plants, dust, or debris. Proper airflow is essential for cooling.


4. Never Ignore Unusual Noise

Grinding, rattling, or buzzing sounds indicate loose parts, motor issues, or damaged fans. Ignoring noise can lead to expensive repairs later.


5. Ensure Proper Room Insulation

Close windows, doors, and curtains to avoid heat from entering the room. This helps the AC cool faster and reduces load.



When to Call The Mistry for AC Repair

If your AC still doesn’t cool or continues to leak water even after basic maintenance, it’s time for expert help. Call The Mistry if you notice:

1. AC not cooling even after cleaning filters

This usually means low gas, blocked coils, or a deeper technical issue.


2. Water leakage from the indoor unit

Blocked drainage requires professional cleaning to prevent repeated leakage.


3. AC making an unusual or loud noise

Loose screws, fan problems, or motor issues must be fixed early.


4. AC cooling for a few minutes and then stopping

This indicates a faulty thermostat, sensor, or compressor issue.


5. Ice forming on pipes or coils

This is a sign of low refrigerant or improper airflow and needs urgent attention.
