Repair the board. Skip the ₹15,000 replacement.
A failed control board does not have to mean a new one. Chennai's voltage swings and monsoon damp quietly kill PCBs, and brands quote ₹8,000-15,000 for a replacement. Our technicians repair inverter and fixed-speed boards at component level — from ₹1,499, with up to a 90-day warranty on the work.
- Board-level component repair
- Save ₹5,000 or more

Signs you need this service
Dead after a power cut
The AC refuses to start once mains power returns — the classic signature of surge damage on the board.
Error codes on display
Inverter units flash E-series codes or a blinking timer light when the board detects a drive or sensor fault.
Compressor never engages
The indoor fan runs but the room stays warm because the board is no longer switching the compressor on.
Random shutdowns mid-cycle
The unit cuts out on its own or ignores the remote — failing relays and dry capacitors behave exactly like this.
MCB trips at startup
A shorted component on the board can pull enough current to trip the breaker the moment the AC starts.
Green corrosion on the board
Sea air near the coast eats copper tracks and solder joints; visible corrosion means failure is close.

Why it’s worth doing properly
Repair-first, on principle
Most service outfits quote a new board because it is easier. We trace the failed component and fix it — you only pay for a replacement when the board is truly beyond saving.
Inverter boards, properly handled
Inverter PCBs from Daikin, LG, Blue Star, Mitsubishi Electric and other major brands need careful drive-circuit work, not guesswork. Our technicians repair them at component level and bench-test before refitting.
Built for Chennai's power
Voltage fluctuation and surge damage are the two failures we see most. We repair the board, show you what failed, and advise on stabiliser protection so the same fault does not return.
Nothing soldered without approval
You get an upfront quote before any work begins, a background-verified technician in uniform, and a GST-registered digital invoice with the warranty stated in writing.
How the visit goes
Book a slot
Tell us the brand, model and what the AC is doing — same-day slots are available, with 60-90 minute reach in covered areas.
Diagnose on site
The technician tests supply, sensors and the board itself, then gives you a fixed quote before touching a soldering iron.
Repair and refit
Simple faults are fixed on the spot; complex inverter boards are repaired and bench-tested before going back into your unit.
Warranty in writing
Your digital invoice lists every component replaced and carries up to a 90-day warranty on the repair.
FAQ
PCB Repair — frequently asked
Everything customers ask before booking a first visit.
When the failed component is correctly identified and replaced with the right spec, yes. We bench-test every board before refitting and run the unit through a full cooling cycle after. The repair carries up to a 90-day warranty, so the risk sits with us, not you.
