Overview
What actually goes wrong with window AC in Delhi
Window ACs are still the most practical choice in a great many Delhi colonies, where there is simply nowhere safe or legal to hang an outdoor unit on a shared external wall. A window AC puts the whole refrigeration circuit into one box, which makes it cheaper to buy, simpler to diagnose and considerably easier to repair. There is no interconnecting pipework to leak and no separate outdoor unit to fail, so faults concentrate in the compressor circuit, the fan motor and the drainage — and almost all of them are economic to fix.
Hard water is the single most common cause of scale inside heating elements, valves and water lines, and scale changes how an appliance fails long before it stops working altogether.
What you get is a technician who tests rather than assumes, a price agreed before the work, and a straight answer if the honest recommendation is not to spend the money at all.
What We Do
What we diagnose and repair
Each of these is diagnosed on site before anything is quoted.
Compressor & Capacitor
Compressors that hum without starting, failed run and start capacitors, overload protectors and relays.
Fan Motor & Blower
Single-shaft fan motors driving both blower and condenser fan, worn bearings, and the rattle of a loose blower wheel.
Coil Cleaning & Servicing
Condenser and evaporator coils jet-cleaned in place, filters cleaned and the drainage slope corrected.
Installation & Sealing
Correct mounting slope, sleeve sealing against water ingress, and the vibration damping that stops a window unit shaking the frame.
Symptoms
When a window AC fault stops being minor
A window AC rarely fails without warning. These are the signs that come first.
- The fan runs but the compressor never cuts in
- Water dripping inside the room instead of outside
- Loud rattling or a metallic knock during operation
- Cooling that has become steadily weaker over a season
- The unit trips the MCB when the compressor starts
- A musty smell each time the AC is switched on
Process
What to expect on the day
You know the price before stage four.
01
Book a slot
Tell us the type, the tonnage if you know it, and the symptom. Gas work and electrical work need different kit on board.
02
Diagnosis on both units
Both units are checked: pressures, capacitor, contactor, fan motors, coil condition, drainage and any stored error code.
03
Price confirmed first
You are told which cause it actually is, what it costs, and whether a clean would do the same for less.
04
Repair or service carried out
Gas is charged by weight after a proper vacuum, never topped up over an unrepaired leak.
05
Cooling measured before we leave
We take the delivery air temperature with you, then hand over the warranty on eligible repairs.

One visit wherever possible
The technician loads the likely parts before setting out, based on what you describe at booking. Most jobs finish without a second trip.
The price before the work
You are told what has failed and what it costs before anything is opened up. Nothing is dismantled on the assumption you will pay for whatever is found.
A warranty you can hold
Warranty available on eligible repairs, plus the manufacturer warranty on any part fitted. Same fault inside that period, we return at no charge.

FAQ
Before you book — the usual questions
Do you carry spare parts to the visit?
Technicians carry commonly needed parts for the brands we work on, so many jobs finish in a single visit. Where a part has to be sourced, we tell you that during the diagnosis and confirm the return visit with you.
The fan works but the compressor does not start. What is that?
Nearly always the run capacitor. It is the single most common window AC fault, an inexpensive part, and a ten-minute replacement. It can also be the overload protector or the relay. A genuinely failed compressor is far down the list of likely causes.
Do you still service older window AC models?
Yes. Window units are mechanically straightforward and parts remain widely available, so age is much less of an obstacle than it is on a modern inverter split. We regularly get twelve and fifteen year old window ACs cooling properly again.
My AC is running but not cooling. What is the likely cause?
In order of how often we find it: a choked filter or condenser coil, low refrigerant from a leak, a failed run capacitor, a seized outdoor fan, and last of all a failing compressor. That order matters — the first two are inexpensive and the last is not, so anyone quoting a compressor without checking the rest is guessing.
Can I book a technician for a weekend slot?
Weekend visits are available across Delhi, subject to technician availability. Weekend slots tend to go first, so it is worth asking a day or two ahead rather than on the morning.
