Rajasthan's summers push air conditioners about as hard as they get pushed anywhere in India — long stretches of extreme heat mean units run for hours a day, often for months at a stretch, which is a very different duty cycle than in cooler parts of the country. That extra load makes regular servicing less of a nice-to-have and more of a genuine necessity, both for comfort and for the electricity bill. Here's a simple way to think about it across the year.
This is the single most important service window of the year, and the one most people leave too late. Book a technician to clean the filters and coils, check the refrigerant gas level, and inspect the drainage — a clogged filter or dirty coil can reduce cooling efficiency significantly and force the compressor to work harder for the same result, which shows up directly on your electricity bill. Booking this in March, before the heat properly sets in, also means shorter wait times than trying to get someone in late April or May when every AC technician in the city is booked solid.
Once the AC is running daily, the main thing to watch for is anything that signals a developing problem before it becomes a full breakdown: reduced cooling despite the unit running constantly, unusual noises, water leaking from the indoor unit, or a noticeably higher electricity bill than the same period last year. Any of these is worth a service call rather than waiting — a small refrigerant leak, caught early, is a much cheaper fix than the compressor damage that can follow if it's ignored for weeks.
Humidity during the monsoon months affects both split and window units — check that the outdoor unit's drainage isn't blocked by monsoon debris, and if the AC has been off for a stretch during a cooler spell, a quick filter check before switching it back on is worth the five minutes it takes.
If you're not using the AC through winter, a basic clean before switching it off for the season means it starts the next summer in better shape, rather than accumulating months of dust that then gets circulated the first time it's switched back on.
For a household running the AC daily through summer, once before the season starts and a mid-season check if you notice any of the warning signs above is a reasonable baseline — more frequent than that is rarely necessary for a unit in good condition, and less frequent than an annual pre-summer service tends to show up as a noticeably higher electricity bill and a shorter unit lifespan.
A thorough AC service covers filter cleaning, coil cleaning (both indoor and outdoor units), checking refrigerant pressure, inspecting the drainage line for blockages, and a basic check of electrical connections. If a "service" is done in ten minutes with nothing more than a quick filter wipe, it's worth asking what else was checked — a proper service on a reasonably dirty unit typically takes 30–45 minutes minimum.
Look for a professional whose profile shows AC servicing or appliance repair as a specific skill or primary trade, rather than someone offering it as an afterthought alongside unrelated work. Reviews mentioning specific brands or unit types you own (split versus window, a specific manufacturer) are a useful signal that the professional has genuine, repeated experience with your kind of unit rather than general familiarity.
