The technician (Noah) that came to service my Buderus blue-flame unit was fantastic! He was knowledgeable, worked quickly and efficiently and was friendly. He explained everything he was doing and why. When he ran into the problem of not having the correct nozzle, he quickly made the decision to use my emergency nozzle I keep for that reason. He promised, and delivered on that promise, to replace the nozzle as quickly as possible. With people like Noah working for your organization, I am more than willing to renew my contract with Folkes in the future.
