After having compared several different heating installers, we opted for GTA because Christian (their installer / co-manager) showed what we felt was an amazing knowledge of the advanced Navien tankless system. We were right; our install went incredibly smoothly and in fact is a more advanced system than those installed in several of our friends' homes (for the same cost). I cannot recommend Christian and GTA highly enough. Great job!
