My Rheem Does Fine
by Wayne
(Altoona, Iowa, USA)
Ours was installed in 1992. Model no. RACC 030 JAS and Serial No. 3528 F1091 3248. We have a 1400 sq. ft. ranch built in 1977 with 3/4 basement located in Iowa.
Fairly well insulated with some large windows and a patio door facing southwest. The central AC unit has never had a problem. We've cleaned it out about once every 3-4 years (I know, we should do it every year). The hvac unit keeps the house cool very well and has been totally reliable.
