10 Best Aircon Installation Services in Singapore (2026)

Putting in new air-conditioning is a different job from servicing what you already own. You are choosing a system size, a brand, a pipe route and an installer, often during a renovation and often for an HDB flat or condominium with its own rules. This guide lists ten Singapore companies that publish an installation service on their own sites, from single-room splits to multi-split systems and commercial setups. Each write-up describes only what the company says about itself, and any licence or dealer wording is its own statement. Use the list to shortlist two or three, ask each for a site visit and an itemised written quote, and compare scope rather than headlines.

Kim's Aircon's installation page is unusually specific about how a job unfolds. It says a survey trip comes first, followed by two installation visits that can be timed around a renovation or an interior designer, then handover. It describes System 1 as a single split and Systems 2 to 5 as multi-split setups, and it names the Daikin, Midea and Mitsubishi Electric model ranges it fits. The company states that it is an authorised dealer for those three brands, and that it will dismantle and dispose of an old system when replacing one. It also lists the situations that can add work, such as different floors, false ceilings or longer pipe runs. Ask for these to be itemised in your written quote.

Kaili Aircon & Electrical is a Woodlands-based company whose site centres on Daikin, with Midea, Mitsubishi, Mitsubishi Heavy Industries, Panasonic and Fujitsu also listed. It describes itself as an authorised Daikin dealer, a statement that is the company's own. Its service list stretches from split units for HDB flats and condominiums to VRV and VRF systems, ductwork fabrication and ACMV control panels, so the same firm could handle a home now and a shop or small office later. The site also mentions upgrading works, and supplying second-hand units and spare parts. It says it offers consultation, installation and after-sales support, and lists maintenance packages. Its footer carries a 2025 to 2026 copyright line, and it publishes a WhatsApp route for enquiries.

The company states that installations carry a three-year installation warranty, and that customers are asked to approve any additional costs before work starts. The footer says it has been providing cold air since 2015, and the site shows a WhatsApp enquiry route.

The steps it publishes run from mounting and piping through electrical connection, pressure testing and a cooling test to a briefing on the remote control.
