KNOW THE COST
A detailed rate card for cleaning and troubleshooting.
Open a service for details. Published rates are in Singapore dollars; confirm the final quote directly. Where a unit reads "per job", HomezyPro may have inferred it from the type of job, and GST is shown only where the company states it.
One-time servicing for one to six units. No GST added.
Routine cleaning of the filters, accessible indoor-unit surfaces and drainage. It is maintenance for everyday dust and dirt; a chemical clean, replacement part or repair may be quoted separately.
How many units does the price cover, and are the blower, drainage and outdoor unit included?
Chemical cleaning, priced by number of units. No GST added.
Chemical cleaning targets built-up dirt on the indoor coil and other accessible components. The amount of dismantling varies, so check how this wash differs from the company's full overhaul.
Which components are cleaned, and will the indoor unit stay mounted during the work?
1 unit, 9,000 or 12,000 BTU
A thorough clean of a wall-mounted indoor unit with components dismantled for better access. Cleaning, reassembly and testing are the main stages.
What is included for your unit's size, and are parts or refrigerant charged separately?
Depends on refrigerant and measured PSI
A refrigerant top-up adds the gas used by the cooling system. The required type and amount depend on the equipment and the diagnosis. Poor cooling alone does not establish that a top-up is needed.
How was low refrigerant confirmed, and what checks or repairs are needed before topping up?
Multi-split; waived if work proceeds
A technician checks the aircon to identify why it is not working as expected. The diagnostic charge may be separate from the cost of repairing the fault or replacing a part.
Is the diagnostic fee credited towards the repair, and will you receive a quote before work starts?

Ah Yong provided a professional and competent service at my HDB. He serviced and cleaned three units for $75, which I thought was very reasonable.

My house’s aircon was not cold anymore and noisy. DJ and Ah Long suggested chemical overhaul for the affected aircon units and it was a big effort and it was done with diligent effort.
HELPFUL TO KNOW
Answer from the company website
Yes - we offer same-day aircon service across Singapore, 7 days a week, subject to availability. We respond to booking requests within 2-4 hours, and if you message us early in the day we can usually send a technician the same day. Our team is on the road island-wide from 8am to 10pm daily, including weekends and public holidays.
Company FAQ sourceAnswer from the company website
Yes. For urgent aircon servicing and emergency repairs - a unit that suddenly stopped cooling, is leaking water, or won’t switch on - we prioritise getting a technician to you as fast as possible, often the same day. WhatsApp us with your address and the problem, and we’ll confirm the earliest available slot. There is no call-out surcharge for out-of-the-way locations.

Company FAQ sourceAnswer from the company website
In Singapore’s climate, most aircon needs a general servicing every 3-4 months - but almost nobody remembers to book it until the unit smells, drips, or stops cooling. A servicing package (also called a maintenance contract) fixes both problems: the visits are scheduled for you across the year, and each visit costs less than booking the same service one-off.
Company FAQ sourceAnswer from the company website
We track when your next servicing is due and contact you to arrange each visit at a time that suits you - you don’t need to remember the schedule yourself.
Company FAQ sourceAnswer from the company website
No - packages cover general servicing visits. If a unit needs a chemical wash or a repair, we quote it separately before any work starts, and regular servicing makes expensive deep cleans much less likely in the first place.
Company FAQ sourceAnswer from the company website
From $55 for a single unit, one-time. Multi-unit bookings cost less per unit - 4 units one-time is $90. Recurring packages start at 2 units (from $115 a year for two units, twice yearly); we are not taking single-unit contracts at the moment.
