Frequently Asked Questions

Which is more energy efficient - window or split AC?

Split ACs are generally more energy efficient, especially inverter models. They can be 20-30% more efficient than window ACs of the same capacity.

Can I install a split AC myself?

No, split ACs require professional installation due to refrigerant handling, electrical work, and proper mounting. DIY installation can void warranty and cause damage.

Which AC is better for a bedroom?

Split ACs are better for bedrooms due to quieter operation (26-35 dB vs 45-55 dB). The compressor noise stays outside, ensuring peaceful sleep.

How long do window and split ACs last?

With proper maintenance, split ACs last 12-15 years while window ACs typically last 8-10 years. Inverter split ACs can last up to 20 years.

Can I use a window AC if I don't have a suitable window?

Window ACs can be installed through walls with proper framing, but this requires more work. Split ACs offer more flexibility in such situations.
