I just wanted to say that John Ryan is the best HVAC technician I ever had come and service my unit. He was friendly and very knowledgable and left me with a great impression. Horizon is lucky to have him as a representative of their company. He did an outstanding job and went over my entire system and spent time explaing what he was doing and how things worked. Horizon continues to amaze me with how well their company relates to their customers and I will continue to recommend Horizon to others.
