How Much Does Aircon Cleaning Cost in Bangkok?

If you have lived in Bangkok for more than a few months, you know your aircon needs regular cleaning. But how much should you actually pay? Prices vary widely, and overpaying is easy if you do not know the market rates.

Standard Prices (2026)

Unit Type	Price Range	Time
Wall-mounted split (standard)	300-500 THB	45-60 min
Wall-mounted split (deep clean)	500-800 THB	60-90 min
Ceiling cassette (4-way)	800-1,500 THB	60-90 min
Floor/ceiling unit	600-1,200 THB	60-90 min
Ducted system	1,500-3,000 THB	2-4 hours

What Affects the Price

Unit type and size: A 9,000 BTU wall unit costs less to clean than a 36,000 BTU ceiling cassette simply because of the size and complexity difference.

Condition: A unit that has not been cleaned in over a year may require a deep chemical clean, which costs more than routine maintenance cleaning.

Access difficulty: High ceilings, tight spaces, or units that require ladder access may incur additional charges.

Number of units: Most companies offer per-unit discounts when you clean multiple units at once. Ask about multi-unit pricing.

How to Avoid Overpaying

• Get quotes from 2-3 providers before committing
• Ask exactly what is included - "cleaning" means different things to different companies
• Be wary of extremely low prices (under 200 THB) - they often upsell aggressively on-site
• Check if the price includes reassembly and testing
• Ask about warranty - reputable companies guarantee their work for at least 7 days

When Cleaning Is Not Enough

If your aircon still does not cool properly after cleaning, the issue may be low refrigerant (gas leak), a failing compressor, or electrical problems. A good cleaning company will tell you this honestly rather than just cleaning and leaving. Learn about our repair service.
