In Lucknow, an AC isn't a seasonal appliance that sits unused most of the year — it's realistically running from March through October, with heavy use May through August. That long a runtime deserves an actual maintenance rhythm, not just a service call whenever it starts acting up. Here's a realistic month-by-month version, not an over-engineered one.
Before you switch the AC on for the season, check the filter and clean it if it's been sitting dusty since October. This is also the right time to book a full servicing if the unit showed any weakness last season — gas pressure checks, coil cleaning, drainage check — rather than waiting until it's 42°C outside and every technician in the city is booked out.
Once you're running the AC daily, the filter clogs faster than people expect, especially if you're near a construction site or a dusty main road. A 2-3 week filter check during peak months is a five-minute task that meaningfully affects both cooling efficiency and your electricity bill.
This is when any underlying issue — low gas, a struggling compressor, a clogged drain — will actually show up, because the unit is running longest and hardest. Watch for: longer time to cool, water dripping from the indoor unit, unusual noise, or the compressor cycling on and off more frequently than normal. Any of these during peak season is worth addressing immediately, not waiting out — a small issue under peak load gets worse fast.
High humidity means your AC is working harder to dehumidify as well as cool, and condensate drainage becomes more important. Check that the drain line isn't blocked — a blocked drain during monsoon is one of the most common causes of water leaking from an indoor unit, and it's a quick clean, not a repair, if caught early.
If you noticed any weakness during the peak months but it wasn't severe enough to stop using the AC, September — as demand on service providers starts easing — is a good window to get it properly checked before next year's season, rather than waiting until next April when everyone else has the same idea.
Give the unit a final clean before extended non-use — a dusty filter and coil sitting for 3-4 months collects more buildup than you'd think, and makes next season's startup rougher. This is also a reasonable time to book servicing if you'd rather not deal with peak-season wait times next year.
Even unused, running the AC for 10-15 minutes once a month keeps the compressor lubricated internally and prevents it from seizing up from total disuse. It's a small habit that avoids a surprisingly common "AC won't turn on at all" issue every March.
None of this needs to be rigid — but a rough rhythm like this, instead of only thinking about your AC when it's already struggling in 43°C heat, is the difference between a unit that lasts 10+ years and one that needs major repairs every other season.
