Blamed air conditioning - that's praiseworthy (9)
I believe the answer is:
admirable
'praiseworthy' is the definition.
(I've seen this before)
'blamed air conditioning' is the wordplay.
'blamed air' anagrams to 'ADMIRABLE'.
Though, I am not sure how this is indicated.
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for admirable that I've seen before include "Deserving of esteem" , "Very well regarded" , "Excellent" , "Outstanding" , "Splendid" .)
