Frequently Asked Questions

Common questions about our aircon servicing in Singapore.

How much does aircon servicing cost in Yishun?
Aircon servicing in Yishun starts from $16 per unit (10+ units). Single-unit pricing: 1 unit $50, 2 units $55, 3 units $70, 4 units $85. These are the same rates whether you live in an HDB flat along Yishun Ring Road or a condo near Khatib MRT. All prices are before GST.
Do older Yishun HDB flats need chemical wash more often?
Older blocks in Chong Pang and Nee Soon Central often have aircon systems that have accumulated years of grime and mould. If your unit has not been serviced in over 6 months, a chemical wash ($80 to $100 per unit) is recommended to restore cooling performance. Mature flats tend to need this more frequently due to aging drainage systems and long-term dust accumulation.
How often should I service my aircon in Yishun?
We recommend every 3 to 4 months for most Yishun households. Singapore's constant humidity and heat mean your aircon runs hard year-round, leading to rapid dirt buildup and mould growth. If you live near ongoing construction like the Chill @ Chong Pang development or new BTO sites along Yishun Avenue 9, consider servicing every 2 to 3 months.
Does Billy Aircon Yishun offer a warranty?
Yes, all services come with a 90-day workmanship warranty. If any issue related to our work occurs within 90 days, Thomas Lim's team will return and fix it at no additional cost. This covers servicing, chemical wash, gas top-up, and repairs.
How quickly can you respond to an emergency repair in Yishun?
We guarantee a response within 24 hours. Because our team is based locally in the North Region, we can often attend to urgent breakdowns in Yishun, Khatib, and Nee Soon faster than island-wide providers. WhatsApp us for priority scheduling.
Can you service ceiling cassette aircon units in Yishun?
Yes. Thomas Lim's team specialises in ceiling cassette servicing, which is common in newer BTOs along Yishun Central and commercial spaces at A'Posh BizHub and North Spring Bizhub. Ceiling cassettes require more time and care than wall-mounted units, and pricing is quoted separately based on the unit type and accessibility.
