Some of what we look at
A few of the things we weigh up before writing our overall take on each provider.
Price
Published package prices for system 1 to system 4 units, what the package includes (piping length, trunking, insulation, dismantling and disposal of old units), extra charges, and whether GST is included.
Quality
Neat piping and trunking, proper insulation and drainage, correct vacuuming and gas charging, and units that cool well without leaks or noise.
Customer service
How quickly they reply and quote, whether a site survey is offered, how honestly they advise on brand and size, and how they handle problems after installation.
Ease of booking
How to get a quote, how soon they can install, and whether they arrange the unit supply, removal of old units and any condo or HDB paperwork.
Reliability
Whether the team turns up on time, finishes in the time promised, cleans up afterwards, and honours the installation and manufacturer warranties.

Lion City Aircon
Lion City Aircon started in 2016, and its founder is known for aircon videos on TikTok. We like that it installs all major brands without tying you to one distributor, and installation customers often describe the crew as careful, clean and friendly. The catch is that several reviews from the past year say standards slipped as it grew, with no-show teams and hard-to-reach customer service. One reviewer wrote, “Now, the workers are always pushing for 5 star google reviews” (Google review, 2026).
A solid pick if you want brand choice and a crew with a good installation record. If fast after-sales support matters most, get a second quote.

Silverback Aircon
Silverback Aircon supplies and installs Daikin, Mitsubishi, Panasonic and Midea systems, and will also fit a unit you've already bought. Many reviews come from long-standing servicing customers who praise thorough work and clear advice, and installation crews are described as polite and careful. The catch is responsiveness: several recent reviews describe slow or no replies, and others mention new units running out of gas within about a year. One long-time customer wrote, “nowadays they don’t reply or answer call at all” (Google review, 2026).
Worth a look if you've bought your own unit and just need it fitted. If fast replies matter to you, we'd compare quotes first.

Cool Channels Engineering
Cool Channels Engineering says it has more than 25 years in the trade, installing Daikin, Mitsubishi, Panasonic and EuropAce systems. Recent reviews are almost all positive, but they're mostly about servicing, with technicians praised as friendly, thorough and punctual. Installation gets less attention, and the one detailed installation complaint is a real concern: a unit that sweated heavily within months, with pipe joints that made later cleaning difficult. That customer wrote that “the air conditioner installation was a nightmare” (Google review, 2025).
A reasonable choice if you also want a reliable servicing team afterwards. Ask for the workmanship warranty in writing, as its length isn't published.

Coldway
Coldway is mainly a servicing outfit that also supplies and installs Mitsubishi, Daikin, Panasonic and Toshiba units. Reviews are overwhelmingly positive, with named technicians praised for punctual, clean work, and we like that it accepts SG Climate Vouchers and says it charges no GST, transport or parking fees for private homes. The catch is that installation reviews are few, and a few mention on-site charges above the advertised price. One customer wrote, “Blower was not dismantled and cleaning is done by brushing off the dust.” (Google review, 2026).
A good option if you already use it for servicing or want to spend your Climate Vouchers. Get the warranty length in writing first.

Tech-V Air Conditioning
Tech-V has been in the aircon business since 1997 and installs Daikin, Mitsubishi and Panasonic systems. Installation reviews are mostly positive, praising fast, tidy installers who explain the new system. The servicing side is weaker, with a repeated theme of technicians pushing chemical washes, gas top-ups or costly parts, and one costly installation later failed because a vacuuming step was skipped. A long-time contract customer wrote that the “recent team always ask for chemical wash and gas top up” (Google review, 2025).
A fair pick for a simple replacement, as long as piping, trunking and disposal are listed in the quote. For an ongoing servicing contract, we'd look elsewhere.

Letscool Aircon
Letscool Aircon supplies and installs all major brands and runs a showroom. Installation reviews are mostly positive, naming installers who arrive early, explain the setup and leave the place tidy, and it offers a 2-year workmanship warranty on installations. After-sales is where it falls short: a noticeable group of recent critical reviews describe units mounted unevenly and leaking, surprise charges, slow replies and problems left unresolved. One wrote that “the aircon installed slanted causing minor leak” (Google review, 2026).
Worth considering if you'd like to see units in a showroom first. Agree any extra charges in writing, and check the unit is level before the team leaves.

City Cooling
City Cooling installs, services and repairs most makes of aircon, and runs quarterly servicing contracts. Recent reviews are mostly short and positive, praising reasonable prices, quick work and polite technicians. The catch is the hard sell, one of the most common review topics with technicians recommending extra work customers felt they didn't need, and the owner's replies often dispute complaints at length. A customer whose site visit was forgotten wrote, “Absolute waste of time engaging them.” (Google review, 2026).
An option if price comes first and you're comfortable saying no to extras. Get the survey findings and full quote in writing, and a second opinion before agreeing to extra repairs.

5 Star Aircon
5 Star Aircon is a family-run firm that installs single-split, multi-split and commercial systems. Reviews are all positive, with customers mentioning quick replies, same-day visits, punctual technicians and no hidden charges, and we like that its package spells out what's included, from brackets to 3m of piping. The downside is how little that record has been tested: the company was only registered in 2024, there are no critical reviews, and few reviews cover installation.
A promising newer choice, especially for multi-split or commercial setups. Ask for the installation warranty terms with the quote, since there's little track record to go on.

BioAire Air Conditioning Solutions
BioAire is a smaller firm that installs and replaces aircon for homes and commercial premises, including smart-home controls. Every review is positive and installation is the most common topic, with friendly installers who explain the options, turn up on time and fit around customers' schedules. One technician fixed a water leak before asking for payment. The weakness is thin, dated evidence: there are no critical reviews and most are two to three years old, so it's hard to judge how it performs today.
Worth a quote if you want smart controls or a smaller, flexible installer. Get the warranty and materials in writing, as no terms are published.

All Best Air-Conditioning & Electric
All Best has sold and installed aircon since 2001, runs a showroom and deals in all major brands. Long-standing servicing customers praise honest advice and fair prices, and reviewers often say its units cost less than at the big electrical chains. The catch is installation quality: critical reviews over many years describe untidy trunking, new units that lost their gas within months, cheaper materials than promised and repeated leaks. One customer wrote, “Terrible and very disappointed with their workmanship.” (Google review, 2024).
Good for comparing unit prices before you buy. If installation quality is your main concern, we'd look elsewhere, or at least get the piping and insulation grade in writing.

Frequently asked questions
How much does aircon installation cost in Singapore?
For a new unit supplied and installed, the installers on this list give rough budgets of about $1,000 to $2,000 for a system 1, $2,000 to $3,000 for a system 2, $3,000 to $4,000 for a system 3 and $4,000 to $5,000 for a system 4, depending on brand and model. If you've already bought the unit, labour-only fitting runs from about $150 to $300 for a bedroom system 1 up to about $500 to $1,250 for a system 4. Reusing sound existing piping and trunking can save $200 to $1,200. Check whether a quote includes GST.
What does an installation package usually include?
Packages usually cover mounting the fan coils and condenser, a set length of copper piping with insulation, trunking, drainage, wiring, vacuuming and pressure testing, gas charging and clean-up. Some include removal of old units; others charge extra for brackets, longer piping or disposal. Most installers set the final price at a free site survey, so ask for the unit sizes, piping length and materials grade in writing.
What warranty should I expect on a new aircon installation?
Among installers that publish their terms, workmanship warranties run from one to two years. Manufacturers typically cover the compressor for five years and the fan coil and other parts for one year. Several installers don't publish a workmanship warranty at all, so ask for its length and what it covers before you pay a deposit.
What should I watch out for when choosing an aircon installer?
The most serious complaints in reviews are about the installation itself: new units that lose their gas or leak within a year, often blamed on piping or skipped vacuuming, units mounted unevenly, and holes or trunking left untidy. Other common complaints are slow replies once the job is paid for and extra services pushed on later visits. Many companies' reviews are mostly about servicing, so look for reviews that describe installations, and keep a written record of what was agreed at the site survey.
