Contacted GGS yesterday morning with a heating issue and two friendly service engineers were at my home by 2:00pm. Diagnosed the problem, fully serviced the ducted heating system (Brevis) and conducted safety checks by 3:30pm. Even had the guys to replace the old temp controller. Service was excellent, safety conscious, pricing competitive and recommend them highly. Thank you GSS Team, you're the team I'll call for all future service/replacements.
