Videocon AC Coil Problem Repair in Chennai
A dirty, corroded or damaged evaporator/condenser coil kills efficiency and cooling.
Videocon split and window air conditioners, especially older models equipped with traditional copper or early-generation blue-fin aluminum coils, often experience severe cooling drops when their evaporator or condenser coils degrade. In coastal city environments like Chennai, salt-laden atmospheric moisture accelerates coil corrosion, leading to pinhole refrigerant leaks and severe airflow restrictions. When the internal or external coils fail, your Videocon AC will run continuously without reaching the set temperature, spiking electricity bills while placing undue strain on the compressor.
Common Symptoms of Videocon AC Coil Failure
- Ice Formation on Indoor Unit: Frost or solid ice buildup on the front evaporator coil matrix due to restricted refrigerant flow or low gas levels.
- Water Leakage Inside the Room: Frozen evaporator coils thawing rapidly, overflowing the condensate drain pan onto your wall.
- Hissing or Bubbling Noise: Audible gas escaping through microscopic corrosion pinholes in the copper or aluminum tubing.
- Warm Air Output: The indoor blower fan operates normally, but the air blowing from the vents remains at room temperature.
- Frequent Compressor Trips: High pressure and heat buildup on a clogged outdoor condenser coil forcing the thermal overload switch to trip.
Likely Causes of Coil Corrosion and Damage
- Formicary Corrosion: Chemical reactions between atmospheric humidity, organic volatile compounds in indoor air, and copper tubing causing pitting leaks.
- Salt Air Oxidation: High humidity and airborne sea salt in Chennai oxidizing raw aluminum fins and exposed copper joints.
- Dust and Grime Buildup: Heavy dust accumulation insulating the coil fins, preventing heat transfer and trapping moisture against the metal.
How Janani Cool Care Repairs Videocon AC Coils
- Nitrogen Pressure Testing: We isolate the indoor evaporator and outdoor condenser coils, pressurizing them with dry nitrogen to pinpoint exact leak locations.
- Precision Gas Brazing: Our certified technicians perform high-temperature silver brazing to seal copper pinholes, or recommend a targeted coil segment replacement.
- Chemical Foam Cleaning: For dirty or blocked coils without leaks, we apply pH-neutral coil cleaning agents to flush out trapped dirt without damaging delicate fins.
- Vacuuming and Refrigerant Recharging: We evacuate the system using a vacuum pump to eliminate moisture, followed by precise R22 or R410A gas top-up according to Videocon specification labels.

Frequently asked questions
Is it better to repair or replace a leaking Videocon AC coil?
If the leak is limited to a single pinhole in a copper coil, high-temperature brazing is cost-effective. However, if an aluminum coil has extensive corrosion or multiple leaks, complete coil replacement ensures long-term reliability.
Why does ice collect on my Videocon AC evaporator coil?
Ice forms when low refrigerant levels from a coil leak cause the coil temperature to drop below freezing, or when heavy dust buildup prevents warm room air from melting the normal condensation.
How long does a Videocon AC coil repair take in Chennai?
Basic chemical coil cleaning takes under two hours, while leak detection, copper brazing, pressure testing, and gas recharging usually take 3 to 5 hours on-site.
Do you offer a warranty on Videocon AC coil repair services?
Yes, Janani Cool Care provides a standard 30-day service warranty on all Videocon AC coil repairs, brazing work, and refrigerant recharges.
