AC Servicing Frequency: There's No One-Size-Fits-All Answer
The short answer is: service your AC at least twice a year. But the real answer depends on several factors — how many hours you run it, where you live, the AC type, and local air quality. Delhi's dusty environment and extreme temperatures mean your AC works harder than in most cities, requiring more frequent attention. Let's break down the ideal servicing schedule for different situations.
Recommended AC Service Frequency by Usage
Your daily usage pattern is the biggest factor in determining service frequency:
Light Use (4–6 Hours/Day)
If you use your AC primarily in the evenings or only during peak afternoon heat, twice-yearly servicing is sufficient. Schedule a pre-summer deep clean in February–March and a post-monsoon service in October. Monthly filter cleaning during May–August will keep it running efficiently.
Moderate Use (8–12 Hours/Day)
This is typical for most Delhi households during summer. Service your AC three times a year: pre-summer (March), mid-summer (June), and post-monsoon (October). Clean filters every 2–3 weeks during peak summer months.
Heavy Use (16–24 Hours/Day)
Common for server rooms, hotels near Delhi Airport, and households with elderly or infant members. These ACs need quarterly servicing (every 3 months) and weekly filter checks during summer. An annual maintenance contract (AMC) is highly recommended for heavy-use scenarios.
Service Frequency by AC Type
Different AC types have different maintenance needs:
Split ACs
Split ACs need servicing every 6 months minimum. The indoor unit's evaporator coil and filters require regular cleaning, and the outdoor unit needs annual condenser coil cleaning. Professional split AC service ensures both units work in harmony.
Window ACs
Window ACs are more exposed to dust and debris. They typically need servicing every 4–6 months. The single-unit design makes them easier to clean but also more susceptible to external dust, especially in areas like Mahipalpur with construction activity.
Inverter ACs
Inverter ACs are more sensitive to refrigerant levels and electrical parameters. While they're more energy-efficient, they require careful professional servicing to maintain optimal performance. Follow the manufacturer's recommended schedule, typically every 6 months.

Signs Your AC Needs Immediate Servicing
Regardless of your regular schedule, service your AC immediately if you notice: (1) Reduced cooling performance. (2) Unusual noises (grinding, rattling, squealing). (3) Water leaking from the indoor unit. (4) Musty or foul smell. (5) AC frequently cycling on and off. (6) Ice formation on the unit. (7) Electricity bill spike. These symptoms indicate a developing problem that will worsen without professional attention.

The Cost of Skipping AC Service
Skipping regular AC servicing doesn't save money — it costs more in the long run. An unserviced AC consumes 10–15% more electricity (₹2,000–₹5,000 extra per year in Delhi). Dust buildup leads to gas leakage from corroded coils. Clogged drains cause water damage to walls and ceilings. The compressor lifespan reduces from 10+ years to 5–7 years. A ₹499 annual service can prevent a ₹10,000+ repair bill.

Frequently Asked Questions
Service your split AC at least twice a year — once before summer (Feb–Mar) and once after monsoon (Oct–Nov). If you use it more than 12 hours daily, add a mid-summer service in June. Clean the filters every 2–3 weeks during peak usage.
