Hot and cold ACs are basically “all weather” air conditioners that work as both AC and room heater. In summer, they cool the room like a regular split AC. In winter, they reverse the cycle and pull heat from outside air, pushing warm air inside. So you are not just blasting electric coils like a blower but using heat pump technology that is usually more controlled and even.
For many homes, that means one unit running through the year instead of dragging out a heater every December. If you live in a city with harsh summers and noticeable winter chill, hot and cold ACs can keep your room comfortable in both seasons, free up floor space and simplify your electricity planning.
LG 1.5 ton 3 Star hot and cold ACs suit people who want one machine for sticky summers and winter nights. Dual inverter, convertible modes and four way swing manage room comfort without bringing out a separate heater.
In most city flats this LG unit keeps a room feel in daily cooling and evening heating. It shows how hot and cold ACs can replace the AC plus heater setup in small and mid sized homes.

What exactly are hot and cold ACs?
Hot and cold ACs are split air conditioners that can both cool and heat a room. In summer, they work like a normal inverter AC. In winter, they reverse the refrigerant cycle, acting as a heat pump and blowing warm air indoors. So instead of keeping a separate room heater, you use one machine throughout the year.
How do hot and cold ACs work in heating mode?
In heating mode, the AC pulls heat from the outside air and transfers it indoors using the same refrigerant loop that handles cooling. The indoor unit becomes the “hot” side and the outdoor unit becomes the “cold” side. A reversing valve switches the flow, and the fan pushes warm air into your room. You still control temperature and fan speed through the remote, just like in summer.
Where do hot and cold ACs make the most sense?
They make the most sense in places with hot summers and a clear winter chill but not extreme sub-zero nights. Think large parts of North and Central India, where you use cooling for months and heating for a few weeks. In those homes, one 1.5 ton hot and cold AC in the bedroom or drawing room can replace both a normal split AC and a small heater.
Are hot and cold ACs better than buying a normal AC plus a cheap heater?
It depends on how you live. If you only need heating for a couple of weeks and mostly sit in one corner, a small heater can still work. But if the room is used by family members, you want even warmth, and you already plan to buy a new AC, a hot and cold unit can be cleaner, safer and less cluttered than a coil heater on the floor. Over a few winters, the running cost difference and the comfort level can justify the higher upfront price.
What should I look for before buying a hot and cold AC?
Check four basics:
- Tonnage that matches your room size (most bedrooms need 1 to 1.5 tons).
- Energy rating, since you will use it in two seasons.
- Inverter compressor, which is now standard for most hot and cold ACs.
- A clear Heat mode or sun icon on the remote, plus a mention of “hot and cold” or “all weather” in the specs.
