The service person was efficient and straight to the point when servicing our needs and he really was very helpful on choosing the system for replacement. And last, the installers showed up 2.5 hours earlier than they stated they would- I was blown away by this alone!!! They simply were over the top on their job performance- simply the best install work I've seen. We are simply extremely satisfied with this company and would Highly recommend them for absolutely anyone needing quality work in service or new installation of a residential HVAC system. YOU GUYS ARE OVER THE TOP! Keep up the GREAT work! GO with this company as you won't be let down! Just ask us. I know all companies, including I.W.P. aren't perfect and will have issues from time to time, but we had a great experience with them; case closed!
