AC buying guide for the Bangladesh summer
Inverter math, ton-per-sqft sizing, and why the cheap AC costs more in 3 years.

Non-inverter ACs cost 25–40% less upfront but consume 40–60% more electricity over their lifetime. In Bangladesh's summer (April–September), payback on the inverter premium is typically 14–18 months.
Appliance.bd sizing rule: 1 ton per 120 sqft for ground-floor north-facing rooms; 1 ton per 90 sqft for top-floor south-facing. Add 0.5 ton for rooms with floor-to-ceiling glass.
Free installation, 0% EMI for 24 months on orders over ৳25,000, and Care Plus extends warranty to 5 years for the cost of a monthly Netflix sub.
