As temperatures rise, air conditioners move from occasional use to daily dependence. However, most breakdowns happen during peak summer, when systems are under maximum thermal load. Preventive maintenance before the season begins ensures operational efficiency, lower electricity consumption, and longer equipment life.
In India, where summer temperatures frequently cross 40°C, neglecting maintenance can lead to compressor failure, refrigerant leaks, and dangerously high indoor humidity levels. Therefore, early servicing is not optional. It is risk management.
What Happens If You Skip AC Servicing?
If an air conditioner is not serviced before summer:
- Cooling efficiency drops by 15–25%.
- Power consumption increases.
- Air quality deteriorates due to clogged filters.
- Internal components accumulate dust and moisture.
- Minor issues escalate into costly repairs.
In short, postponing maintenance often results in higher electricity bills and emergency repair costs during peak demand months.
Types of ACs Commonly Used in Homes
1. Split Air Conditioner
A split AC has two units — indoor and outdoor. It offers efficient cooling and quieter performance. Most urban homes prefer this system.
2. Window Air Conditioner
A window AC is a single-unit system installed in a window or wall opening. It is economical but slightly noisier compared to split ACs.
Maintenance requirements differ slightly, but core servicing principles remain the same.
Step-by-Step AC Maintenance Checklist Before Summer
1. Clean or Replace Air Filters
Filters accumulate dust, pollen, and particulate matter. A clogged filter restricts airflow, forcing the compressor to work harder.
- Clean filters with mild detergent.
- Replace damaged filters.
- Ideally, check every 15–30 days during heavy usage.
2. Inspect and Clean Coils
Both evaporator and condenser coils accumulate dirt. Dirty coils reduce heat exchange efficiency.
- Professional deep cleaning improves cooling performance.
- Coil cleaning reduces compressor strain.
3. Check Refrigerant Levels
Low refrigerant causes insufficient cooling and ice formation on coils. A technician should:
- Check pressure levels.
- Identify leaks.
- Recharge refrigerant if required.
Refrigerant imbalance directly affects system thermodynamics.
4. Examine Electrical Components
Loose wiring, faulty capacitors, or burnt contactors can lead to sudden shutdowns.
- Tighten connections.
- Inspect control boards.
- Test thermostat calibration.
Electrical inspection ensures operational safety.
5. Clean Drain Line and Tray
Clogged drainage lines cause water leakage and indoor dampness.
- Flush the drain pipe.
- Remove fungal buildup.
- Ensure proper slope for water flow.
This step prevents indoor water damage and mold growth.
6. Check Outdoor Unit Clearance
The outdoor condenser needs proper airflow.
- Remove debris and leaves.
- Ensure at least 2 feet of clearance.
- Avoid direct obstruction.
Blocked airflow reduces heat dissipation efficiency.
Energy Efficiency Benefits of Early Maintenance
When serviced before peak summer:
- Cooling improves instantly.
- Power bills reduce by 10–20%.
- Compressor lifespan extends.
- Carbon footprint decreases.
Efficient ACs consume less electricity, especially during high-tariff summer months.
Ideal Time for Servicing
The best time for AC maintenance is:
- Late winter (February)
- Early spring (March)
During this period:
- Service charges are lower.
- Technician availability is higher.
- Emergency demand is minimal.
Waiting until May often results in delayed appointments and premium pricing.
DIY vs Professional Servicing
Basic cleaning (filters, visible dust removal) can be done at home. However:
- Gas refilling
- Electrical diagnostics
- Deep coil cleaning
must be handled by certified technicians. Attempting complex repairs without expertise may void warranty.
Cost of Pre-Summer AC Maintenance in India
Average servicing cost ranges between:
- ₹500–₹1,500 for basic servicing
- ₹2,000–₹4,000 for deep cleaning and gas top-up
Compared to compressor replacement (₹8,000–₹15,000), preventive servicing is far more economical.
Signs Your AC Needs Immediate Attention
Do not delay servicing if you notice:
- Weak airflow
- Unusual noise
- Water leakage
- High electricity bill
- Bad odor from vents
These are early warning indicators of system stress.
Final Thoughts
AC maintenance before summer is not just about comfort. It is about efficiency, cost control, and durability. A well-maintained air conditioner cools faster, consumes less power, and survives harsh summer conditions without breakdown.
In simple terms: service early, save money, stay comfortable.
