After sitting idle through the cooler months, your AC needs a proper check-up before Kolkata's brutal summer arrives. The worst time to discover a fault is during the first heatwave, when every service centre is overbooked and you are left sweating for days.

A little preparation now prevents a mid-summer breakdown. Here is a simple pre-summer AC maintenance checklist to get your unit ready:

1. Clean or Replace the Air Filters

This is the single most important step.

  • Why it matters: Months of dust settle on the filters while the AC is off. Dirty filters choke airflow, weaken cooling, and can freeze the coil.
  • What to do: Slide out the filters, rinse them under running water, dry them completely, and refit them. If they are torn or badly clogged, replace them.

    • 2. Inspect and Clean the Outdoor Unit

    The outdoor condenser does the heavy lifting of releasing heat.

  • Why it matters: Leaves, dust, bird droppings, and cobwebs collect on the outdoor unit over winter, blocking heat dissipation and straining the compressor.
  • What to do: Clear any debris around the unit and book a professional jet cleaning of the condenser coils for best results.

    • 3. Check Refrigerant Gas and Cooling Performance

    Test the cooling before you actually need it.

  • Why it matters: A slow gas leak over the off-season can leave you with warm air on day one of summer.
  • What to do: Run the AC in cool mode for 15 minutes and check whether it cools properly. Weak cooling or ice on the copper pipes means it is time for a gas pressure check.

    • 4. Test Electrical Components and the Remote

    Small electrical faults turn into big failures under summer load.

  • Why it matters: Weak capacitors, loose wiring, and a tired remote often fail right when the AC is pushed hardest.
  • What to do: Replace the remote batteries, confirm the AC responds correctly, and have a technician check the capacitor and wiring during servicing.

    • 5. Book a Professional Pre-Season Service

    The smartest item on the checklist.

  • Why it matters: A professional service catches hidden problems—frozen coils, choked drains, gas leaks—before they ruin your summer.
  • What to do: Schedule a deep jet wet servicing in February or March, well ahead of the rush.
