Im starting to get closer at understanding the HVAC options we have and now we seem to have narrowed it down to 2 very capable contractors, both well quallified, both offering 10 year Parts and Labor warranties, both offer service 24/7 and both are good companies. Now one of the contractors are selling the Trane XLi products, the other offering Lennox Elite heat pump systems and air handlers. The Trane is a 14 seer the Lennox as configured a 13seer approach. The systems are as follow 5 ton, 2 1/2 ton and a 2 1/2ton in the studio. All calcs were computer generated and Manual J right off the plans. The down stairs came out to be 4.7 Ton..

So, now I have to decided, Trane or Lennox.. Both Good (my last house was Lennox, no problems at all in 13 years).

So, what do you guys think?
