In summary

Annual AC servicing is recommended for most households, but the ideal frequency depends on usage, environmental conditions and manufacturer guidance.


  • Annual servicing: Helps inspect key components and identify developing faults.
  • Frequent use: Daily operation or dusty surroundings may require more frequent maintenance.
  • Home care: Clean filters regularly and keep the outdoor unit free of obstructions.
  • Professional help: Arrange an inspection for poor cooling, water leakage, ice formation or unusual noises.

You can also buy a new AC on Easy EMIs at over 1.5 lakh partner stores across 4,000 cities, including Reliance Digital, Croma, and Vijay Sales. 

Why is regular AC maintenance important?

Regular AC maintenance helps keep the air conditioner clean, efficient and reliable. Dust accumulation, blocked drainage and neglected components can affect cooling performance over time. Routine maintenance also helps identify potential problems before they lead to expensive repairs or unexpected breakdowns.

  • Shop at 1.5 lakh partner stores across 4,000+ cities.
  • Select your preferred model and check your eligibility for the Insta EMI Card or Easy EMI Loan.
  • Split the purchase cost into monthly payments.

Is it necessary to service an AC every year?

Yes, annual professional servicing is a sensible maintenance practice for most air conditioners. It helps check important components, clean areas that are difficult to access and identify potential faults. In hot or dusty regions, or where an AC runs for several hours daily, servicing may be needed more frequently.


An annual service does not mean every component needs cleaning or replacement each time. The technician should inspect the unit and recommend maintenance based on its condition and the manufacturer's guidelines.

What are the benefits of servicing an AC every year?

Regular servicing helps keep an air conditioner in good working condition and may reduce the risk of unexpected breakdowns.


  • Maintains cooling performance: Cleaning filters and inspecting coils can help maintain airflow and heat transfer.
  • Supports energy efficiency: A well-maintained AC may use energy more effectively than one with restricted airflow or dirty components.
  • Helps prevent breakdowns: Inspections can identify worn parts, drainage blockages and other issues early.
  • Improves indoor air quality: Cleaning accessible filters and suitable internal components helps remove accumulated dust.
  • Checks water drainage: Clearing a blocked condensate drain can help prevent water leakage.
  • May extend equipment life: Appropriate maintenance can reduce avoidable strain on components.

How often should you service an AC?

The recommended frequency depends on usage, environmental conditions and the type of air conditioner. Use the manufacturer's maintenance schedule as your primary guide.


AC usage or conditionSuggested maintenance approach
Occasional useArrange professional servicing at least annually, subject to the manufacturer's guidance
Daily use for several hoursConsider servicing before the main cooling season and inspect the unit during periods of heavy use
Dusty environment or high pollutionCheck filters more frequently and arrange coil inspection when needed
Commercial or continuous useFollow a more frequent maintenance schedule based on operating hours
Reduced cooling, unusual noise or water leakageArrange an inspection promptly rather than waiting for the annual service

What happens if you do not service your AC every year?

Skipping servicing may allow dirt, drainage problems and worn components to go unnoticed. Over time, these issues can affect cooling, airflow and reliability.


  • Reduced airflow: Dust-clogged filters can restrict the air moving through the unit.
  • Poor cooling: Dirty coils or other faults may reduce heat transfer and cooling performance.
  • Water leakage: A blocked drain line or dirty drainage components may cause water to drip indoors.
  • Higher energy consumption: Restricted airflow or inefficient operation can increase the electricity required to maintain the desired temperature.
  • Unexpected repairs: Small problems may worsen if they remain unaddressed.
  • Unusual smells or noise: Dust, moisture or mechanical issues may require inspection and cleaning.

What is included in annual AC servicing?

The exact service checklist depends on the AC type, manufacturer and service package. A typical professional inspection may include:


  1. Air filter cleaning: Removing dust from washable filters or checking whether a filter needs replacement.
  2. Coil inspection: Checking the indoor evaporator coil and outdoor condenser coil for dirt or damage.
  3. Drainage inspection: Checking the condensate tray and drain line for blockages.
  4. Electrical checks: Inspecting accessible wiring and electrical connections for signs of damage.
  5. Cooling performance check: Assessing airflow, temperature difference and overall operation.
  6. Outdoor unit inspection: Checking the condenser, fan and accessible components for obstructions or unusual operation.
  7. Fault diagnosis: Investigating symptoms such as poor cooling, abnormal noise or repeated shutdowns.

Annual servicing is generally recommended for an AC that is used regularly because it helps maintain efficiency, cooling performance, and reliable operation. Routine maintenance can identify issues such as clogged filters, dirty coils, drainage problems, refrigerant-related issues, and loose electrical connections before they become more serious.

An unserviced AC can gradually experience reduced cooling, restricted airflow, higher energy consumption, poor air quality, water leakage, and more frequent breakdowns. Dust accumulation and unresolved minor faults can place additional strain on the system. Regular maintenance can help identify and address these issues earlier.

Servicing can help reduce avoidable energy consumption by maintaining clean filters and coils, suitable airflow, and proper operation of components such as the thermostat. An AC that can cool effectively may require less operating effort than one working with restricted airflow or dirty heat-exchange surfaces.

Repair may be suitable when the AC has a manageable fault and remains in reasonable overall condition. Replacement can be considered when the unit has repeated breakdowns, significant component faults, declining efficiency, or repair costs that are no longer practical compared with purchasing a suitable replacement.

AC filters should generally be cleaned according to the manufacturer's instructions and the level of dust and usage. Frequently used ACs or homes with higher dust levels may require more frequent filter cleaning than occasionally used units. Clean filters help maintain airflow and support efficient cooling.
