First I called ARS and they responded in less than a day but came to my house stating that the AC would die within 3 months and to fix what I have would cost $3500. Guess what, I called Larson Air, they were on plus cleaned the coils, replaced the insallation and many other things .. but then 3 of the repairs that ARS said I needed were proven to be totally bogus. Thank you Larson Air for being honest and having resonable prices. I will always contact your for my heating and AC needs.
