I live in the Boston area, where the A/C season is relatively short – about two months. But when it’s hot it’s hot! ;-) I’m checking with contractors for a new central A/C system for my home and did some reading.
I read a review by Consumer Search here http://www.consumersearch.com/www/ho...fullstory.html . I’d like to have at least 15 SEER and I also like the two stage idea. (Any comments about these preferences, coming from a totally "green" newbie?) The review recommends three systems that fit these specs. The top of the line is the Carrier Infinity 18, and than come Amana’s 16 SEER RSG Ultron and Bryant Two-Speed Puron Plus 598B. All these units use Puron. The Carrier seems to have many bells and whistles but it costs $2000 more than the Bryant and $2300 more than the Amana. Plus, the Amana comes with a lifetime warranty. In addition, the review mentions that the Amana uses a scroll compressor ”which is quieter and has less repairs”. (I assume the quoted prices in the review are for the condenser only, but I’m not sure.)
All things considered, which unit should I get?
Also, normally, do most contractors offer just one brand with which they are familiar with, or do they offer a few brands? My first quote is due soon and by then I’ll know the heath load. The estimator mentioned only Carrier. At this point I can provide these details about the house: A two story colonial with four bedrooms on the second floor and three rooms and a kitchen on the first floor. Total living area is about 1800 Sq ft plus a finished basement which is so far not included in the system.
