How we score

Every number on this page comes from public Google data collected on the date shown, not from opinion or payment. Rating is the business’s live Google star average. Review volume is how many customers have rated them, ranked against other Singapore HVAC companies. Confidence weighs the rating by that volume, so a rating built on thousands of reviews carries more weight than one from a few dozen. Recency reflects how recently people are still leaving reviews. No business can pay to change these numbers.

How much does HVAC servicing cost in Singapore? (2026)

Several companies on this page publish their own pricing directly, which we cite here rather than a third-party estimate. General servicing typically starts around $12.80 to $25 per unit depending on the company, with chemical wash and overhaul costing more. Always confirm the current price and any transport fees before booking.

Job	Typical price
General servicing (per unit)	$12.80, $25
Chemical wash (per unit)	$40, $80
Chemical overhaul (per unit)	$60, $180+
New system installation (per unit)	From $1,050

Ranges compiled August 2026 from published pricing on 338 Aircon, Letscool Aircon, and Lion City Air Conditioner Services’ own websites. These are the businesses’ own listed rates, not third-party averages, so confirm current pricing directly before booking, as promotions and per-brand costs can vary.

Serving all of Singapore

These HVAC companies serve homes and businesses island-wide, with technicians dispatched across residential and commercial properties in Singapore. If you’re searching for HVAC services near me, most offer same-day or next-day appointments, so check current availability when you call.

What to ask before you book HVAC servicing

What’s the total cost, including any transport fee, before you start?
Do I actually need a chemical wash or overhaul, or would a general service be enough?
How many years of experience does the technician assigned to my job have?
Is there a warranty on the parts or workmanship?
Can you support my specific aircon brand and model?

Frequently asked questions

How did you choose these HVAC companies?

We started from every HVAC and aircon servicing company in Singapore with a public Google presence, then ranked by rating, review volume, consistency and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

What’s the difference between general servicing and a chemical wash?

General servicing is a routine clean of filters, coils and drainage, while a chemical wash is a deeper clean recommended for units struggling to cool properly or affected by mould and grime buildup, usually costing more.

How often should I service my aircon in Singapore?

Most companies recommend general servicing every 3 months given Singapore’s humidity, with a chemical wash annually or as needed if cooling performance drops. Ask your chosen company for a recommendation based on your usage.

The bottom line

SoCool’s sheer review volume makes it the safe default, while Lion City’s perfect rating and no-upsell reputation stand out if honest pricing matters most to you. Get a written quote before any chemical wash or overhaul either way.
