The team of Vlad, Alik, Sansa and Vitali installed a new heating unit in our residence Aug. 12,2015. The team showed up on time and started working right away. To protect our floor at the working area and passageway up to the front door, they laid tarp type protection. All accessories and the old heating unit they removed, they brought outside right away for them to dispose of.. After the installation of the new unit, they removed the tarp and vacuumed all the areas they worked on. The place looked as clean and as orderly as before they started the installation. They showed us how to operate the new unit. The installation looks very neat and professionally done. The team are very respectful, too.
