7 Reasons Your AC Is Not Cooling — Samastipur
Low Refrigerant Gas (Most Common in Samastipur)
Refrigerant is the chemical that actually cools the air. If your AC has a leak, the gas level drops and cooling stops — even though the compressor is running. You might notice the AC "blows air" but it's not cold. In Samastipur's summer heat, a low-gas AC struggles even more. This is the #1 cause of AC not cooling that we fix every day.
Signs: AC blows slightly cool air (not cold), indoor unit gets icy frost, electricity bill rises sharply.
Repair Cost: ₹700–₹1,600 ⚠️ Do not DIY — needs professional toolsDirty / Clogged Air Filter
The AC filter catches dust from your room air. In Samastipur — where dust from roads, farms, and construction is constant — filters clog up fast. A clogged filter blocks airflow to the evaporator coil, drastically reducing cooling. This is the one problem you can actually check yourself.
Check it yourself: Pull out the indoor unit panel, remove the filter mesh. If you see thick dust/grey coating — that's your problem. Clean it with water and dry before reinserting.

Dirty Condenser Coil (Outdoor Unit)
The outdoor unit releases heat from your room outside. In Samastipur, outdoor units get covered with dust, cotton fluff (from nearby fields), and sometimes bird nests. A dirty condenser can't release heat properly, so the AC can't cool effectively.
Signs: Outdoor unit feels excessively hot, AC cools slightly in the morning but stops by afternoon when temperature peaks.
Repair Cost: ₹400–₹800Compressor Not Working Properly
The compressor is the "heart" of your AC. Without it, refrigerant can't circulate and cooling stops completely. A faulty compressor can be caused by: dirty condenser (overheating), low gas (running dry), or electrical surges — which are very common in Samastipur due to voltage fluctuations.
Signs: Loud clicking sound when AC starts, AC turns on then immediately shuts off, complete absence of cooling despite fan running.
Repair Cost: ₹800–₹5,000 ⚠️ Call a technician immediatelyFaulty Thermostat / Temperature Sensor
The thermostat tells the AC when to stop cooling (when it reaches the set temperature). A faulty thermostat might "think" the room is already cool, so it cuts the compressor early. This gives you a room that never gets cold enough.
Signs: AC cuts off cooling too early, temperature display shows wrong reading, compressor cycles on/off unusually fast.
Repair Cost: ₹400–₹1,200Frozen / Iced Evaporator Coil
This sounds counterintuitive — ice forms but no cooling? When the coil freezes over (due to dirty filter or low gas), it blocks airflow completely. The fan blows air, but it passes over a block of ice instead of a cold coil. You'll notice water dripping from the indoor unit.
Quick test: Switch off the AC for 2–3 hours (fan only, no compressor). If it starts cooling again, you have a freezing issue that needs a technician to fix the root cause.
Repair Cost: ₹300–₹1,500 (depending on cause)PCB / Circuit Board Fault
Modern ACs have a PCB (Printed Circuit Board) that controls all functions. Voltage spikes from Samastipur's frequent power fluctuations can damage the PCB. A faulty PCB can cause the compressor not to start, incorrect mode operation, or the AC to behave erratically.
Signs: Blinking indicator lights, error codes on display, remote control unresponsive, AC does random things.

⚠️ Voltage Problems in Samastipur — Protect Your AC
Samastipur frequently experiences voltage fluctuations, especially during peak summer when load is high. We strongly recommend installing a voltage stabilizer (1.5–2 KVA) for your AC if you don't already have one. Cost: ₹800–₹2,000. It protects the compressor and PCB from damage that can cost ₹3,000–₹5,000+ to repair. Ask us during your next visit — we can recommend the right stabilizer.
Should You Repair or Replace Your AC?
If the repair cost is more than 50% of the price of a new AC, and your AC is already 8–10 years old, replacement may be more economical. We'll always give you an honest assessment before recommending major repairs. At Repair Guru Samastipur, we work for you — not for the parts bill.
