Same-Day Aircon Servicing, Island-Wide
We’re based in Jurong West and serve every estate in Singapore. Our technicians are most frequently in these areas, where same-day slots are easiest to secure:
Our Aircon Services
Servicing, chemical wash, repair, maintenance, gas top-up and installation, one experienced team for every aircon job, at home or at work. Same-day slots are available for urgent problems across Singapore.
Aircon Servicing
Regular aircon servicing every 3 months keeps your unit cooling like new. We clean the filters, coils and drainage, check the gas level and test performance, so you get colder air, lower bills and fewer breakdowns.
Aircon Chemical Wash
When normal servicing isn’t enough, a chemical wash deep-cleans the coils and parts to strip out mould, dirt and bacteria. It restores cooling power, kills musty smells and is the fix for units that leak water.
Aircon Repair
Weak cooling, water leaks, strange noises or a unit that won’t start, we diagnose fast and fix most common faults on the spot. High-quality parts, honest advice, and no work you don’t need.
Aircon Maintenance
Scheduled maintenance contracts for homes and businesses. We service your units on a fixed schedule, spot problems early, and keep everything running efficiently, without you having to remember to book.
Aircon Gas Top Up
Low refrigerant means warm air and rising bills. We check for leaks first, not just top up and go, then refill to the correct level (R22, R410A or R32) and test the cooling before we leave.
Aircon Installation
New aircon for your HDB, condo, landed home or office? We assess your space, recommend the right capacity and brand for your budget, and install it precisely, no oversized units, no shortcuts.
How Often Should You Service Your Aircon?
In Singapore, you should service your aircon every 3 months for regular home use, and monthly for heavy or commercial use. Our year-round heat, humidity and dust clog filters and coils faster than in most countries, so waiting longer means weaker cooling, higher electricity bills and a bigger risk of breakdowns.
Regular servicing also keeps the drainage system clear, which prevents the water leaks and mould that Singapore’s humidity causes. And many manufacturers require proof of regular servicing to keep your unit’s warranty valid.
Signs your aircon needs servicing now:
✗ Cooling feels weaker than before
✗ Water dripping or leaking from the unit
✗ Musty or sour smell when it starts
✗ Ice forming on the pipes or coil
✗ Louder than usual, or rattling
✗ Electricity bill creeping up
Noticing two or more of these? Book a servicing before it turns into a repair, WhatsApp us for a same-day slot.

FAQ
How often should I service my aircon in Singapore?
Every 3 months for regular home use, and monthly for heavy or commercial use. Singapore’s year-round humidity and dust clog filters and coils quickly, regular servicing keeps cooling strong and prevents expensive breakdowns.
What's included in a standard aircon servicing?
Cleaning of the filters, front panel, cooling coils and blower; clearing and flushing the drainage tray and pipe; checking the refrigerant level; tightening electrical connections; and testing cooling performance before we leave.
How much does aircon servicing cost?
It depends on your number of units and the type of service needed. WhatsApp us your unit count and we’ll send you a clear quote within minutes, what we quote is what you pay.
What's the difference between general servicing and a chemical wash?
General servicing is regular cleaning and testing to keep a healthy unit running well. A chemical wash is a deep clean that dissolves the mould, sludge and bacteria inside the coil that normal servicing can’t reach, it’s the fix when cooling stays weak, the unit smells musty or keeps leaking despite regular servicing.
Do you offer same-day aircon servicing?
Yes, subject to available slots. Message us early in the day for the best chance of a same-day appointment, island-wide.
How long does aircon servicing take?
Typically 30–60 minutes for a standard servicing, depending on the number of units. A chemical wash takes longer.
Why is my aircon not cold even after servicing?
The most common causes are low refrigerant (needing a gas top-up) or heavy internal buildup (needing a chemical wash). If we serviced your unit and it’s still not cold, contact us, we’ll come back under our workmanship warranty and diagnose it honestly.
Why is my aircon leaking water?
Usually a clogged drainage pipe or dirty coils causing condensation to overflow, both are fixed by servicing. If leaking continues after cleaning, the unit may need a chemical wash or a repair, and we’ll tell you which before any work.
Which brands and property types do you service?
All major brands, Daikin, Mitsubishi, Panasonic, Midea, LG, Hitachi, Toshiba, Samsung and more, across every property type: HDB, BTO, condo, landed and commercial, island-wide.
Is there a warranty on your servicing?
Yes, every servicing job is covered by our workmanship warranty. If the same problem returns shortly after our visit, contact us and we’ll come back, diagnose it and put it right at no extra cost.
