Aircon Installation Singapore: Survey-Led, Fixed Quotes, 90-Day Warranty

What Aircon Installation Covers

Aircon Installation is the right service when you are fitting out a new home, replacing a failing unit, adding a multi-split to a renovated room, or commissioning a cassette or ducted system in an office or shop. Every install starts with an on-site survey so the quote reflects the real pipe-run length, electrical capacity, and ledge access of your unit, not a guess from a phone description. We work across HDB, condo, landed, and commercial properties Singapore island-wide.

The install scope covers wall-mount split, multi-split, cassette, and ceiling-concealed ducted units across all major Singapore aircon brands. R32 is the current Singapore standard and requires an NEA licence to charge, which our technicians carry. R410 and legacy R22 units are also handled where the existing system requires it. Every job ends with a vacuum-tested line set, a manufacturer-spec refrigerant charge, a cooling performance reading, and a 90-day workmanship warranty card.

When You Should Book a New Installation

Standard servicing keeps a clean, healthy aircon running. A chemical wash clears coil biofilm. Installation is what you book when there is no working unit to keep alive, when the existing unit is past the point that any wash can save, or when you are adding an indoor unit to a system that did not have one before.

Five hard indicators that point to install territory rather than repair:

1. A unit older than 10 to 12 years that is already on its second or third major fault. Compressor fatigue, refrigerant leaks at the coil, and PCB age all stack up. Replacement usually beats another repair on cost over the next two years.
2. A new BTO, condo, or landed property with no aircon yet. Wall pipe paths and ledge positions need to be planned alongside renovation, so the survey should happen during the renovation window, not after.
3. An existing system that needs a second or third indoor unit. Multi-split outdoor units have a fixed indoor capacity. We check whether your current outdoor can take the extra load before quoting the indoor install.
4. A commercial space (office, F&B, retail) being fitted out for opening. Cassette, ducted, and ceiling-concealed installs need to work around the ceiling design and opening hours, often out-of-hours scheduling.
5. A poor third-party install that cools weakly from day one. An under-vacuum line set or a sloppy R32 charge will not be fixed by another wash. The survey identifies the actual fault and quotes either a re-commission or a clean replacement.

If you are not sure whether you need a fresh install or a repair, the fastest path is a WhatsApp message describing the unit age, the symptom, and the room. We can usually narrow the right call from the description, then confirm on-site.

How a Survey-Led Install Differs From a Default Quote

A default-led aircon installation starts by quoting from a phone description. The number assumes a short pipe run, easy ledge access, and a standard electrical run, which often turns out to be wrong on install day. The customer then faces top-up charges for extra copper, longer wiring, or a heavier bracket, with no time to compare alternatives.

A survey-led install flips the order. We measure the pipe run from the indoor wall position to the outdoor ledge, check the consumer-unit capacity, review the bracket and drainage path, and only then put a fixed quote in writing. If the survey shows the existing electrical run cannot carry the new load, we say so up front and quote the upgrade rather than discovering it half-way through the job. The fixed quote becomes the price you pay, with no top-up surprises on the day.

We work on all major Singapore aircon brands, including Daikin, Mitsubishi Electric (Starmex), Panasonic (Enviro), Toshiba, LG, Midea, and Fujitsu. The install procedure is similar across brands; the variation is in the bracket spec, the indoor drain pan layout, and the manufacturer commissioning step that the brand requires for warranty registration. Our technicians know the brand-specific commissioning steps from doing them every week.

Refrigerant Types and Brand Compatibility

R32 is the current Singapore standard for new installs, fitted in most new Daikin, Mitsubishi Starmex, Panasonic Enviro, and other major-brand units. R32 charging requires an NEA licence, which Aircon Chemical Wash SG (by Billy Aircon) holds. The licence documentation is kept on file and the R32 charge is recorded on every install receipt for warranty and future service records.

R410 is the mid-generation refrigerant used on many 2010s installs. New units sold in this refrigerant class are now uncommon, but reinstall and replacement work on existing R410 systems remains routine. R22 is the legacy refrigerant for installs from before the late 2000s. Recovery and disposal of residual R22 from an old unit during replacement is handled under NEA-compliant procedures, with the new unit running R32.

Multi-split installations need careful capacity matching between the outdoor condenser and the combined indoor unit load. We check the manufacturer specification for your existing outdoor unit before quoting any additional indoor install, and we say so if a second outdoor unit is the cleaner long-term answer.

Local Coverage and Response Time

We cover Singapore island-wide for aircon installation, with site-survey slots usually available within the same week and install dates booked in once the quote is approved. Two dedicated emergency teams stay on standby for active no-cooling and replacement-urgency situations. Our regular weekly run takes us through Bedok, Tampines, Jurong, Woodlands, Ang Mo Kio, Punggol, Sengkang, Toa Payoh, Bukit Batok, Yishun, Serangoon, and Geylang, so survey response time depends mostly on how full the day already is rather than where you live.

Landed homes, CBD office buildings, and jobs starting after 6 PM carry a clearly-quoted add-on that we confirm on WhatsApp before booking. The install scope, vacuum step, R32 commissioning, and 90-day workmanship warranty are identical to HDB and condo work.

Pricing and What to Expect

Aircon Installation pricing is survey-led. The on-site survey produces a written line-item quote covering the unit (if we supply), copper pipe length, electrical run, bracket, drainage extension, and labour. Customer-supplied units are fine as long as they are factory-sealed and the manufacturer warranty card is intact. R32 charging is included in the install price, carried out under NEA licence and documented on the digital receipt.

Common add-ons that are quoted separately when the survey shows they are needed include consumer-unit upgrades for higher-capacity units, longer copper runs beyond a standard 3 to 5 metre pair, false-ceiling access work for cassette installs, removal and disposal of an existing aircon unit, and out-of-hours scheduling for commercial fit-outs. Payment is by PayNow, bank transfer, or cash on the day. A digital receipt is issued after payment, useful for warranty claims, manufacturer registration, and tenant handover records.

For most Singapore homes and offices, an Aircon Installation visit either commissions the new unit cleanly on the install day or hands you a fixed written quote for the survey-confirmed scope before any work begins. WhatsApp the unit type, room layout, and address and we will book the site survey. For ongoing care after install, Non-Dismantle Chemical Wash every 3 to 4 months and a Full-Dismantle Chemical Overhaul at the 12 to 18 month mark keep the unit running at near-new performance for the long haul.
