Clarify what (inside and outside unit) and how they clean before you order. 

I’ve used Charlie and his team for years. Cleaning , repair, and when he observed that the original installers hadn’t grounded the compressor units, I had him do that as well. If it doesn’t need cleaning or service, he’ll tell you too. 

Just had Charlie come with his professional crew and clean 4 of my air con units.   Absolutely one of the best, if not the best.

 

Thanks to the above posters for his recommendation.   

Agree on Charlie.

How much does he charge for cleaning?

 

Btw, here is his Facebook page: https://m.facebook.com/ChangInterChiangmai/

I had 4 a/c units cleaned.    500 baht per unit.   I didn't think about bargaining.    It's totally worth it.  They did a super job.    They moved anything that needed moving and cleaned up as if nothing moved.
