My new AC was installed on July 27/15, during the heat wave. The new unit would not cool my home below 26 degrees and would sometimes still get as warm as 31 degrees. So, for the following 10 days, I almost had a technician in on a daily basis to assess what the problem was. Each technician came up with a different theory as to what it might be, and would tell me they did this or that to fix it and that all should be fine from that point forward. But it still continued to not cool properly. Finally the last technician found a piece of debris clogging a drain hose, which with the removal of that piece, has made it finally work. But it STILL does not work as well as the unit that was in place prior to this new one. I know the technician said there is insufficient surface area on the existing coil, and this is a common problem with high velocity systems like mine. What I don't understand, is why did it take so many technicians to come through my home on so many days (all of which I would have to stay put for upto 4 hours window), before one was finally experienced enough to find the problem, and be able to explain further why it is still not working at it's best capacity??
My bedroom level is still far too warm and I have to sleep with a fan on most nights. This should not be the case after having a brand new AC installed!
