Simple, honest tips to keep your AC cooling well, lower your electricity bill, and make it last longer — from the MUJO Aircon team. No jargon, just practical advice for Chennai homes.
Catch these early and you avoid a bigger, costlier repair later.
If your AC takes too long to cool or never feels cold, the filters or coils are likely dirty, or the gas is low. A service usually fixes it.
Rattling, buzzing or grinding sounds mean a loose part or a motor issue. Don't ignore it — small fixes now prevent big damage.
A musty smell means mould in the filter or drain. A burning smell means an electrical problem — switch off and call us immediately.
Water dripping from the indoor unit usually means a blocked drain pipe. Easy to clear during a service.
A dirty or low-gas AC works much harder and eats more power. A service often pays for itself in savings.
Simple habits that lower your monthly bill without buying anything new.
Every degree lower can use about 6% more power. 24–26°C is comfortable and much cheaper than 18–20°C.
Dusty filters block airflow and make the AC struggle. You can gently wash and dry them yourself once a month.
At night, set the timer or sleep mode so the AC doesn't run cold all night — you sleep well and save power.
Seal gaps and keep doors shut so cool air stays in and the AC doesn't run non-stop.
A ceiling fan spreads the cool air, so you can set a higher temperature and still feel comfortable.
A serviced AC cools faster and uses less power. Regular service is the cheapest way to keep bills low.
A well-kept AC runs for years. A neglected one fails early.
Once before summer and once after. Regular professional servicing keeps every part healthy.
Don't stack things around the outdoor unit. It needs open air and space to release heat properly.
Running at 16–18°C all day strains the compressor — the most expensive part. Keep it at 24–26°C.
A small noise or weak cooling is cheap to fix now. Left alone, it can damage the compressor.
A few things are safe to do yourself. The rest needs a trained technician.
Wash the filters, keep the remote batteries fresh, clear space around both units, and set the right temperature.
Gas filling, weak cooling, water leaks, strange noises, bad smells, electrical issues, and any installation or relocation.
Don't open the electrical parts or add gas yourself — it's unsafe and can damage the AC. Always call a trained technician.
