If you still looking for a trustworthy air con guy, can try to find one here http://askthewhale.com/merchants/list/air%20con Got long list of air con contractors and some have been reviewed before. Maybe useful for you. Anyway @dean air con servicing usually go by number of fan coils and whether it is chemical cleaning or regular cleaning. Not all air con require chemical cleaning, sometimes they try to upsell you but really no need one. I see prices hovering around $30 for cleaning of each fan coil unit, can be cheaper but be wary lo.

I came across this website called askthewhale.com. Not bad leh can find a list of local pest control companies that have been reviewed. If you all still can't find one you like can try to find one here. http://askthewhale.com/merchants/list/pest%20control
