My AC unit started blowing hot air the evening of a very hot day. The forecast was even hotter for the next day and I have an infant and a 19 month old! He came by right away and fit me into his schedule. I was expecting the worst, that my unit is dead and I'll need to replace the whole thing. But he figured it out in minutes and the fix was less than $250! So glad to call myself a customer of Modern Air Solutions!
