“

The contractor demonstrates inconsistent performance with one client praising five years of timely, quality work and technician John's analytical skills in solving a complex floor heating issue, while another client reported unprofessional installation of their geothermal system three years prior that required corrections, including collapsed metal ducts, unresponsive communication, and failure to pull required permits. A third client experienced poor project management during their geothermal retrofit, receiving upcharges for design corrections and installation work, unreliable scheduling coordination with subcontractors that resulted in property damage, and recommendations for overpriced electrical services, though the installation team itself performed well.
