Elliott Brothers performed a new install of two Lennox Elite Series XP20-036-230 units, two CBX40UHV-036-230 air handlers with ECB40-9CB heat strips, and two Lennox I comfort S30 thermostats. All new duct work (supply and returns) were installed. Brannon was very professional through the whole process, from quote to install. The install of the equipment was professionally done, with all supply duct work and return duct work cleanly run through the attic space. Very happy with the work performed.
