I dealt with Emily (office), Brian (Manager), Nic (Sales), Layne (Service), Brian and Kenneth (Installers) on this job and it felt like I had the support from the entire company. Everyone involved in my transaction was incredible and helped me answer all 10,000 questions and concerns I had. (No way was I an easy customer on this one.). Everyone was incredibly responsive and always on time or even early. I had a new 5 ton Trane system installed along with a electronic air Cleaning system with a UV lamp, ionizer, and electronic filter system. Xcalibur was not the cheapest but also not the most expensive. This team and product was worth every penny spent. I highly recommend you letting them check out your needs.
