Looking for recommendations for a complete new A/C unit . Eventually I will be needing a new one . In no major rush tho , just thought I'd ask around . Have had some minor problems with mine over the years. Still works fine though. It's 16 years old. When it is time though , I just want "the basic" , the lowest sear 13 or 14 ??? My house is about 1400 sq.ft. . Any recommendations of A/C companys or cost would be appreciated . THANKS :)
