the point you're making is exactly the reason for the cliche of 'money wont buy you happiness". it is the thought that buying these things (that give us momentary happiness) will equate to long term happiness. in 20,30,40 years, how airconditioned your apartment was (or wasn't) will have little bearing on your overall level of happiness at that point.
also, your last few sentences contradict what you wrote earlier. you said you don't get unhappy unless theres a specific reason, right after you gave 3 examples of you being unhappy without a real reason.
Not having air conditioning and sweating when there's 40 degrees Celsius is pretty unhappy moment. Not sure how he contradicted himself there. I can totally see where he is coming from. Having comfortable car, comfortable place to live can certainly give you long term happiness. I am sure in 20,30,40 years down the road if I won't have comfortable car and comfortable place to live I will be unhappy.
On that whole note. What is happiness? It's what we ourselves decide it to be. For me happiness is when I am content with myself.
