FAQs — Commercial Heatwave Cooling
Which cassette AC is best for commercial heatwave cooling?
The Daikin FCNQ24MV1 is the best for commercial heatwave cooling — rated for 48°C ambient, handles continuous 10-hour operation, gold-fin dust protection. For offices needing quiet operation, the LG CT-Q24GAVN0 at 34 dB is the best choice.
How much does commercial cassette AC cost to run during heatwave?
A 2-ton inverter cassette AC running 10 hours daily during heatwave consumes 415–440 units/month — 25–35% more than normal. At Delhi's commercial tariff (₹8/unit), this costs ₹3,320–3,520/month. Inverter models save 30–40% versus non-inverter.
Is inverter cassette AC worth buying for commercial use?
Absolutely. Commercial spaces run AC 10–14 hours daily for 6–9 months. An inverter cassette saves ₹12,000–14,400/year versus non-inverter. The payback on the ₹8,000–12,000 inverter premium is under 12 months for commercial use.
What is the best temperature setting for office during heatwave?
Set 24°C during peak heat (12–4 PM). Raise to 26°C in morning and evening. Pre-cool 30 minutes before staff arrival. Each 1°C increase saves 6–8% electricity. The BEE recommends 24°C as the optimal balance of comfort and efficiency.
