If you are looking for reliable air conditioning repair in Kolkata, you are in the right place.
Step outside right now in Kolkata and you will feel it instantly. The air hits you like a hot, wet towel. As of April 2026, temperatures in the city are hovering between 27°C and a scorching 40°C, with humidity levels touching 74% to 78% by the end of the month. It is, without question, one of the most brutal summers the city has seen in years.
And then it happens. You walk back indoors, reach for the remote, point it at your AC and… nothing. A weak wheeze. Warm air. Or worse, complete silence.
That moment of panic is something thousands of Kolkata residents experience every single summer. Your air conditioner is not just a luxury right now. It is your survival gear. And when it breaks down, you need air conditioning repair that is fast, reliable, and done right the first time. That is exactly what this guide is for.
Why Kolkata’s Summer is Brutally Hard on Air Conditioners
Before we talk about repair, let us understand why your AC is struggling in the first place. Kolkata does not just get hot. It gets hot AND humid at the same time, which is a brutal double punch for any air conditioning system.
Here are the real weather numbers right now:
| Weather Factor | April 2026 Data |
|---|---|
| Maximum Daytime Temperature | 36°C to 40°C |
| Minimum Night Temperature | 25°C to 27°C |
| Average Humidity | 69% to 78% |
| Daily Sunshine Hours | 8 to 10 hours |
| UV Index | Extreme (11+) |
| Feels Like Temperature | 40°C to 45°C+ |
When your AC runs for 12 to 16 hours a day in these conditions, it gets pushed far beyond its comfort zone. Coils freeze up, gas levels drop, filters choke with dust, and compressors overheat. Skipping regular AC service in a city like Kolkata is like skipping oil changes on a car you drive 500 km every day.
Top 10 Signs You Need Air Conditioning Repair Right Now
A failing AC rarely dies suddenly. It sends warning signals for days or weeks before completely giving up. Here is what to watch for:
- AC is running but not cooling the room – This is the most common complaint. The air coming out feels warm or just slightly cool. It usually points to low refrigerant gas or a dirty condenser coil.
- AC is making strange noises – Rattling, squealing, clicking, or grinding sounds are never normal. These often mean loose internal components, a failing fan motor, or compressor issues.
- AC is leaking water inside the room – A small amount of condensation outside is fine. But water dripping indoors means a blocked drain line or frozen evaporator coil.
- AC is giving off a bad smell – A musty odor usually means mold or bacteria buildup in the filters or coils. A burning smell is more urgent and could indicate an electrical fault.
- Your electricity bill has suddenly spiked – A struggling AC works harder and uses more power. If your power bill has jumped without any change in usage patterns, your AC efficiency is declining.
- AC trips the circuit breaker repeatedly – This is a serious warning sign pointing to electrical faults inside the unit and needs immediate professional attention.
- AC does not turn on at all – Could be a PCB failure, capacitor issue, or power supply problem. Do not try to fix this yourself.
- Ice forming on the outdoor unit or copper pipes – A sign of refrigerant leak or airflow restriction. Running a frozen AC causes serious compressor damage.
- Remote control is not responding properly – Sometimes it is the remote, but it can also be a signal board issue inside the AC.
- Rooms are cooling unevenly – One side of the house is cold while another is warm. Often a ducting or airflow problem.
If you are experiencing even one or two of these, do not wait. Kolkata’s summer is only getting hotter. Book a technician visit before a small problem turns into a full compressor replacement.
The Most Common Air Conditioning Repair Problems in Kolkata
Based on thousands of service calls across Kolkata, here are the most frequently repaired AC issues:
1. Refrigerant Gas Leak or Low Gas Level
This is the number one reason why ACs in Kolkata stop cooling. The refrigerant (commonly called “gas”) is the substance that actually absorbs heat from inside your room and releases it outside. When levels drop due to a leak, your AC simply cannot do its job.
Signs: Warm air from vents, ice on the copper pipes, hissing sound. Fix: Leak detection, sealing the leak, and recharging the gas to manufacturer specifications.
2. Dirty or Clogged Filters
In Kolkata’s dusty, humid air, filters get choked in weeks rather than months. A blocked filter restricts airflow, forces the compressor to overwork, and dramatically reduces cooling performance. This is also a major cause of the musty smell many people notice.
Fix: Deep cleaning of filters, coils, and drainage tray. One Point Solution’s Jet Cleaning service uses high-pressure water jets to flush out every bit of dust and grime.
3. Faulty Capacitor
The capacitor gives the compressor and fan motors the initial jolt of electricity needed to start running. When it fails, the AC either will not start or starts and immediately shuts off. Capacitor replacement is one of the most affordable split Air Conditioning Repair in Kolkata jobs, usually fixed within an hour.
4. Compressor Failure
The compressor is the heart of your air conditioner. It pressurizes the refrigerant and drives the entire cooling cycle. Compressor failure is the most expensive repair, often caused by running the AC with low gas for too long, electrical surges, or simple old age.
Signs: AC runs but produces zero cooling, loud knocking sound from outdoor unit. Prevention: Regular maintenance is genuinely the only way to avoid this.
5. PCB (Printed Circuit Board) Failure
Modern inverter ACs are controlled by sophisticated circuit boards. Power fluctuations, which are extremely common in Kolkata, can damage the PCB and cause erratic behavior or complete shutdown. This is a precision repair that needs a trained technician with the right diagnostic tools.
6. Blocked Drain Line
The drain pipe carries condensation water from the indoor unit outside. In Kolkata’s humid summer, this pipe can develop algae and mold growth, causing a blockage. Result: water dripping inside your room and potential ceiling damage.
Fix: Drain line flushing and anti-algae treatment, part of a standard service visit.
Air Conditioning Repair vs. Replacement: How to Decide
This is a question every AC owner faces at some point. Here is a simple framework to help you decide:
| Situation | Recommendation |
|---|---|
| AC is under 5 years old with a repairable fault | Repair it |
| Repair cost is less than 50% of a new AC price | Repair it |
| Compressor failure on an AC more than 8 years old | Consider replacement |
| Frequent breakdowns every season | Consider replacement |
| AC is no longer energy efficient (old star rating) | Consider upgrade |
| Only minor issues like gas refill or capacitor | Always repair |
For most Kolkata households, a properly serviced AC should run efficiently for 8 to 12 years. The key is not ignoring the early warning signs.
What Happens During a Professional Air Conditioning Repair Visit
Many people wonder what exactly a technician does during a service or repair call. Here is a step-by-step breakdown of what One Point Solution’s technicians cover:
Step 1: Visual Inspection The technician checks the indoor and outdoor unit for obvious signs of damage, corrosion, water leaks, or electrical issues.
Step 2: Performance Check They run the AC and measure the actual cooling output, airflow, and pressure levels to identify the problem accurately.
Step 3: Filter and Coil Cleaning Filters, evaporator coils, and condenser coils are cleaned to restore full airflow and heat exchange efficiency.
Step 4: Gas Pressure Check Refrigerant pressure is tested. If low, the team identifies and seals the leak before recharging.
Step 5: Electrical Component Testing Capacitor, PCB, thermostat, and all wiring are checked for faults, wear, or burn marks.
Step 6: Drain Line Cleaning The drainage pipe is flushed and cleared of any blockage.
Step 7: Final Performance Test After repairs, the AC is run and tested again to confirm it is cooling properly before the technician leaves.
This systematic approach is what separates a professional Air Conditioning Repair in Kolkata from a quick.

AC Maintenance Tips to Avoid Frequent Repairs
Prevention is always cheaper than repair. Here are practical habits that extend your AC’s life and keep it performing at its best through Kolkata’s brutal summer:
Sign up for an Annual Maintenance Contract (AMC) to get scheduled professional servicing without having to remember it yourself
Clean or replace filters every 3 to 4 weeks during peak summer months
Schedule a professional service at least once before summer begins and once after monsoon ends
Keep the outdoor unit clear of leaves, dust, and debris that block airflow
Use a voltage stabilizer if your area has frequent power fluctuations (most of Kolkata does)
Do not set the thermostat below 20°C – 24°C to 26°C is the sweet spot for both comfort and efficiency
Run the fan-only mode for 10 to 15 minutes after switching off the AC to dry out internal moisture and prevent mold
Frequently Asked Questions (FAQ)
Q1. How much does air conditioning repair cost in Kolkata?
The cost of air conditioning repair in Kolkata depends on the type of fault. Simple jobs like filter cleaning or capacitor replacement typically cost between Rs. 400 and Rs. 1,200. Gas refilling ranges from Rs. 800 to Rs. 2,500 per kg. Major repairs like PCB or compressor work can go up to Rs. 18,000. One Point Solution provides a free diagnosis so you know the exact cost before any work begins.
Q2. Why is my split AC running but not cooling the room?
The most common reasons are low refrigerant gas, a dirty or blocked filter, a frozen evaporator coil, or a failing compressor. In Kolkata’s high-humidity environment, dirty filters are the most frequent culprit. A professional split AC repair technician can diagnose and fix this within a single visit.
Q3. How long does a typical Air Conditioning Repair in Kolkata take?
Most standard repairs like gas refilling, filter cleaning, capacitor replacement, or drain line unblocking are completed within 1 to 3 hours. Complex repairs involving PCB replacement or compressor work may take longer depending on parts availability.
Q4. Is it better to repair or replace an old Air Conditioning Repair in Kolkata?
If your AC is under 8 years old and the repair cost is less than 40 to 50 percent of a new unit’s price, repair is almost always the better financial decision. If the compressor has failed on a unit that is over 10 years old, replacement is usually more cost-effective in the long run. One Point Solution also offers used AC sales in Kolkata if you need an affordable replacement option.
Q5. How often should I service my Air Conditioning Repair in Kolkata?
Given Kolkata’s extreme heat and humidity, air conditioners here work much harder than in other cities. Ideally, you should get a professional service at least twice a year. Once in March before summer peaks, and once in October after monsoon season. If your AC runs 12+ hours a day, quarterly servicing is highly recommended. An Annual Maintenance Contract (AMC) with One Point Solution handles all of this automatically.
Do Not Wait Until It Breaks Completely
Kolkata’s summer waits for nobody. With temperatures at 36°C to 40°C and humidity pushing past 78%, a working AC is not a comfort choice – it is a health necessity, especially for children, elderly family members, and anyone working from home.
