> Every price below was read on the operator's own website, app listing or official Facebook page on 30 September 2026. We excluded Penang "landing pages" that turned out to be nationwide lead-generation sites with no local address, and one Penang-branded site whose phone number sits on a KL lead-gen page.
Re-checked 14 October 2026. Daikin has raised its single-unit Go Clean prices since 30 September: Pro on a 1.0 to 1.5HP wall unit is now RM209 (was RM190) and Basic RM180 (was RM140). The three-unit Value Pack is unchanged at RM499, and an October code, HAZE40, takes RM40 off single-unit bookings until 31 October. Acson, AC2U and Ban Leng's published prices, and Ban Leng's installation rate card, are unchanged.
Re-checked again 31 October 2026. HAZE40 ends today. Daikin posted its replacement the same evening: DEAL51, an 11.11 code that keeps the RM40-per-unit discount and adds RM11 Touch 'n Go eWallet cashback, valid until 15 November 2026. Go Clean, Value Pack, Acson, AC2U and Ban Leng prices are all unchanged from 14 October.
Penang's heat does not let up, and most homes on the island and in Seberang Perai run their aircond for hours every day. That makes servicing a routine cost rather than a one-off, and the price you pay depends on three things that are rarely shown side by side: whether the outdoor unit is cleaned, whether gas is included, and whether you book one unit or several.
Searching for a price is harder here than in KL or Johor Bahru. Many results for "aircond service Penang" are nationwide websites with a Penang page and no Penang address. We set those aside and kept operators we could tie to a real Penang or Seberang Perai address, or to a manufacturer page that lists Penang as a service area.
How to compare aircond servicing quotes
- Indoor only or indoor plus outdoor? Daikin's Basic and Acson's cheaper package clean the indoor unit only. A full service includes the outdoor condenser, which is where dust and leaves cut efficiency. Compare like with like.
- Normal service or chemical wash? Ban Leng defines a general service as filter, blower, drain pan, drain line and a test run, and an overhaul as dismantling, a chemical clean of both units, vacuuming and a gas refill. The price gap between the two is large.
- Is gas included? Daikin's FAQ says gas is not included in Go Clean. Acson includes a free refrigerant-level check. AC2U says its RM150 includes refilling.
- How many units? Daikin cuts the price for three units at one address. Acson gives discounts when you buy two or more packages in its app.
- Warranty. Daikin and Acson both give a 60-day workmanship guarantee. AC2U gives 90 days. The local shops we checked do not publish one.
How often to service
The operators do not agree. Daikin recommends every six months. Ban Leng and AC2U both suggest a general service every three to four months, and AC2U adds that the outdoor unit should be cleaned at least twice a year. For a bedroom unit running every night, the shorter interval is worth considering; for a rarely used guest room, twice a year is enough.
Daikin's November code: DEAL51
The October HAZE40 code ends on 31 October. The code live now is DEAL51: RM40 off each unit on a single-unit Go Clean booking until 15 November 2026, with no cap on the number of units, plus RM11 Touch 'n Go eWallet cashback capped at one per order. It is limited to the first 500 redemptions nationwide, not valid on Value Packs or with other vouchers, and the cashback goes to the TNG eWallet registered to the booking phone number within 45 working days of approval. Worked out on a 1.0 to 1.5HP wall unit:
- One unit, Pro: RM209 minus RM40 = RM169.
- One unit, Basic (indoor only): RM180 minus RM40 = RM140.
- One unit, Pro, after cashback: RM169 minus the RM11 credit = RM158 effective.
- Three units, Pro: RM169 x 3 = RM507 with the code, or RM496 once the single RM11 credit lands, against RM499 for the Value Pack. That is a RM3 difference, and the pack is paid once with nothing to wait for, so for three units at one address the two routes are effectively level.
For one or two units, the code is the cheaper route. Ban Leng, SejukAihh and NAS Aircond publish no promo, and Acson's discount applies only when you buy two or more packages in its app.
How to pick
If you want a fixed price and a named company standing behind the job, book Daikin Go Clean or Acson in their apps. Both service other brands. Daikin is cheaper per unit if you have three units, Acson includes a gas check. If you live on the mainland and want the lowest published price, SejukAihh in Bertam advertises RM99 and AC2U RM150 with gas. For installation or a bigger repair, Ban Leng, a Bukit Mertajam dealer since 1985, publishes a full installation rate card even though servicing is by quote.
Whoever you book, ask three questions before the technician arrives: is the outdoor unit included, is gas included, and what happens if the unit is still warm a week later.
