5 Best Aircon Servicing Companies in Singapore (2026) — Reliable, Reasonable, & On Time

Around since 2007, Cool Earth has built its reputation on transparent, itemised pricing — every line item is shown on the homepage before any booking, which is unusual in an industry where 'WhatsApp for quote' is the default. Published rates start at S$50 for a single unit and step down sharply with volume (S$55 for 2 units, S$70 for 3, S$85 for 4, dropping to S$16/unit at 10+ units). They cover all the major brands you'd expect — Daikin, Mitsubishi, Panasonic, Fujitsu, LG, Samsung, Toshiba — and still service older R22 systems, with a 90-day workmanship warranty on every job. Booking is WhatsApp-led with replies typically inside a few minutes, and same-day service is genuinely available. Best for households who want to know exactly what they're paying before a technician shows up.

Operating since 2003 with a 26-strong technician team and over 15,000 jobs completed, Billy Aircon is the high-volume HDB specialist on this list. The team size is what lets them back up a 24-hour response guarantee that smaller outfits simply can't promise. Pricing follows a similar sliding tier — single unit S$50, dropping to S$16/unit once you hit 10 or more, which makes them genuinely useful for landlords managing several tenanted flats from one booking. Coverage is island-wide (Bedok, Tampines, Yishun, Jurong and basically every estate in between) and they support the standard residential brand list. Chemical wash starts at S$80 (non-dismantle) and runs S$130–180 for a full overhaul, with a 90-day workmanship warranty. Best if speed and HDB-friendly pricing matter more than fancy booking software.

What sets LK Brothers apart is upfront, on-page pricing — none of the 'WhatsApp us for a quote' gatekeeping. Their Gold Servicing tier is S$25/unit (minimum 2 units; usual S$40), and they actively promote a yearly contract priced at S$215 for 3 units that bundles all four quarterly visits for the year (usual S$280, so roughly 23% off). Chemical wash is also flat-priced at S$210 for 3 units. This visibility makes them one of the most predictable players for budgeting — the price you see is the price you pay, and the upsell pressure most aircon customers dread isn't really part of the experience. Best for households who want to lock in a fixed annual cost at the start of the year.

Everyworks runs as a one-stop home services platform (aircon plus plumbing, electrical, and handyman) and has the strongest digital booking experience on this list. The whole flow happens through WhatsApp — you message a description or photo of the issue and their 'Smart Diagnosis' team replies with a quote, no phone calls involved. The platform claims more than 75,000 customers served and a 4.9 average rating, and they back work with a 'Happiness Guarantee' rework policy if you're not satisfied. Operating hours are 8am–10pm daily, which is unusually wide for the trade. Pricing isn't published on the homepage, so you'll need to start a chat to get specifics — but for users who genuinely hate phone calls and just want to type a description and have someone show up, that's the appeal.

SoCool is worth knowing if your aircon situation is more complex than a couple of HDB units — they actively service VRV/VRF, ducted, and chilled-water systems alongside standard residential setups, which most five-best guides skip over entirely. Brand coverage is broader too, including Carrier and Midea on top of the usual Daikin/Mitsubishi/Panasonic/Fujitsu line-up. They handle full part replacements (PCB boards, fan motors, capacitors, expansion valves, thermistors), which means a single visit can resolve issues that smaller outfits would push to a second appointment. 90-day workmanship warranty applies. Pricing isn't published — you'll need to request a quote — but for landed homes with mixed systems, light commercial spaces, or unusual brand combinations, the technical scope justifies the extra step.
