Aircon servicing
in Singapore

Aircon in Singapore works overtime, so regular servicing isn't optional lah. For units running daily, several firms listed here suggest a general service every three to four months. A general service cleans the filters, coil, tray and drainage. A chemical wash goes deeper, for musty smells, weak cooling or leaks that normal servicing can't fix. A chemical overhaul means dismantling the fan coil for a full clean, usually for heavily clogged units. Before booking, ask: is the price per unit or per visit, is GST included, is gas top-up extra, and how long is the workmanship warranty?

Free listings are in no particular order and none of them is a paid placement. The labelled Paid #1 slot is a separate bid. Details come from each business's own website. We do not add ratings or customer reviews.

Common questions

How often should I service my aircon?: For typical home use, several firms in this directory suggest a general service every three to four months, more often for heavy or commercial use. If cooling drops, it smells musty or it starts leaking, don't wait for the next visit.
General servicing, chemical wash or chemical overhaul: which one do I need?: General servicing is routine cleaning and checks. A chemical wash cleans the fan coil more deeply with chemicals, usually without full dismantling. A chemical overhaul dismantles the unit for a thorough clean and is meant for badly clogged units. A good technician should inspect the unit and explain why before upselling you.
Do I need a gas top-up every time?: No. A top-up only makes sense when the technician finds the refrigerant is low, and low gas can mean there's a leak that should be checked first. Ask which refrigerant your unit uses (R22, R410A or R32), since top-up prices often differ by type.
What should I check in a quote?: Check whether prices are per unit or per visit, whether GST is included, whether chemical wash prices only cover smaller (9,000–12,000 BTU) units, whether there's a transport or attendance fee, and how long the workmanship warranty lasts.
How were these listings picked? Are they ranked?: They're in no particular order, and none of them is a paid placement. Each business's details come from its own website, checked on 21 Oct 2026. Prices and hours change, so confirm with the business before booking. Business owners can ask us to correct their listing.
