Every split air conditioner sold in Kuwait carries two numbers on its label, not one. The first is T1, measured at mild temperatures; the second is T4, measured hot. In August, the second is the one that concerns you.
The gap is neither small nor fixed. A Whirlpool WMVOA180/1 is labelled 18,000 BTU and delivers 14,945 at T4 — a 17 per cent loss — at 189.900 dinars. Its bigger sister, the WMVOA240/1, goes from 23,300 to 19,039, a 18.3 per cent loss.
Compare across brands and the gap widens. A Midea MIKAG1-24HRF-I falls from 24,000 to 16,400 — 31.7 per cent. A Gree GIK-LP36GM5(I) falls from 34,800 to 32,400, only 6.9 per cent. Two units with similar first numbers behave completely differently in summer.
At Best Al-Yousifi a Gree GSK-CO18GM5C(I) goes from 18,000 to 15,185 at 157.900. On a Panasonic CS-UV18XKF-4 the shop prints “55°C ambient” beside the second number — the only place we found the temperature written as a figure.
A warning about the naming. LG’s own Kuwait page for the I27TTC gives 22,000 at standard conditions and 18,500 at T3, with an operating range of 18 to 54 degrees. The Kuwaiti shop calls that same number T4. The letter is a market label here, not a single standard. The Gulf standard GSO 2530 excludes Kuwait in its own text, and the local reference is the Public Authority for Industry’s requirements.
Then come the installation terms, which are what stop the day. At Xcite: five metres of gas pipe free with units from 18,000 to 36,000, three metres with 12,000 and under, and every extra metre at 6 dinars. Removing the old unit is 7 dinars. A pre-purchase site visit is 10 dinars, deducted from the invoice.
Three conditions kill an installation where it stands: the outdoor unit may not be mounted higher than three metres; the indoor unit must sit within a metre and a half of the power point; and if you want the pipes inside the wall, you must fit a plastic sleeve of at least three inches yourself. Units of 36,000 and above need an external supply point of 30 amps — that is the seller’s published condition, not a ministry rule we could confirm.
Compare before you pay. Eureka: an extra metre is 6 dinars in its table, removing the old unit 10, a gas charge 10 per unit, and relocation 25 within the house, 35 within the area, 45 between areas. A paragraph on the same page says 4.5 a metre while the table says six; the table is the one that binds.
Best Al-Yousifi: extra pipe 7 dinars a metre, removing a wall unit 10, a cassette 25, gas 15, and running a new power point 75 dinars.
The warranty is identical in figures and different at the start: a full year and five years on the compressor at both — but Eureka counts from the invoice date and Best from the date of operation.
What they refuse, in words, and it is the same list at both: no civil work, chipping, welding, glass or aluminium cutting, or core holes in ceilings and beams; drains are not connected to the main drain; a new unit is not fitted onto old pipes, and if you insist there is no cooling guarantee; outdoor units are not hung on white block; and running an inverter unit off a generator voids the warranty.
The price ladder, from Xcite’s catalogue: Wansa Gold one ton, 11,600 at T4, 119.900; Wansa Gold ton and a half, 14,100, 129.900; Haier 14,400, 149.900; Wansa Diamond two ton, 19,400, 149.900; Hisense 14,200, 169.900; Hitachi 23,000, 239.900; a Hisense floor-standing 31,000, 439.900; a Hisense cassette 37,532, 569.900.
So, in order: read T4 and not T1; count the metres from the indoor position to the outdoor one before you buy; ask about amperage if the unit is large; and book the survey if the wall is not ready — ten dinars that come back on the invoice is cheaper than a cancelled installation day.
