Hi I have central air conditioning that I believe is not cooling quick enough. Last night when it was already dark (no sun) I started air conditioning and it took 2 hours do decrease house temperature by 2 degrees C or 3.6 Farenhite (From 29 to 26C or from 84.2F to 80.6F). I have new Carier furnice so my blower is working good but I do suspect that air that comes out is not cool enough. I do realize that my unit could be udersized for my house, but is there anything else I should look at? Like should I measure (how?) temperature of coming out air? What should it be? My airconditioning is I believe 2 or 3 tons (not sure). It is about 3 years old.
I am located in Toronto, Ontario.
Thanks for your recomendations in advance.
