AC Care & Maintenance Tips
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.
5 Signs Your AC Needs Service
Catch these early and you avoid a bigger, costlier repair later.
Weak or slow cooling
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.
Strange noises
Rattling, buzzing or grinding sounds mean a loose part or a motor issue. Don't ignore it — small fixes now prevent big damage.
Bad smell
A musty smell means mould in the filter or drain. A burning smell means an electrical problem — switch off and call us immediately.
Water leaking inside
Water dripping from the indoor unit usually means a blocked drain pipe. Easy to clear during a service.
Sudden high electricity bill
A dirty or low-gas AC works much harder and eats more power. A service often pays for itself in savings.
Cut Your AC Electricity Bill
Simple habits that lower your monthly bill without buying anything new.
Set it to 24–26°C
Every degree lower can use about 6% more power. 24–26°C is comfortable and much cheaper than 18–20°C.
Clean the filters monthly
Dusty filters block airflow and make the AC struggle. You can gently wash and dry them yourself once a month.
Use timer / sleep mode
At night, set the timer or sleep mode so the AC doesn't run cold all night — you sleep well and save power.
Close doors & windows
Seal gaps and keep doors shut so cool air stays in and the AC doesn't run non-stop.
Run a fan with the AC
A ceiling fan spreads the cool air, so you can set a higher temperature and still feel comfortable.
Service every 3–6 months
A serviced AC cools faster and uses less power. Regular service is the cheapest way to keep bills low.
Make Your AC Last Longer
A well-kept AC runs for years. A neglected one fails early.
Service twice a year
Once before summer and once after. Regular professional servicing keeps every part healthy.
Keep the outdoor unit clear
Don't stack things around the outdoor unit. It needs open air and space to release heat properly.
Don't over-cool
Running at 16–18°C all day strains the compressor — the most expensive part. Keep it at 24–26°C.
Fix small issues early
A small noise or weak cooling is cheap to fix now. Left alone, it can damage the compressor.
