Heating system was inspected and cleaned. The work was done very well and the technician kept us informed of his work as he went on. He was very professional and friendly. He also inspected the water heater for gas leaks.
We had Greiner replace our old HVAC system with a modern heat pump and air handler. They’ve always been very responsive, courteous, knowledgeable and professional. We’re very happy with the new system and glad that we chose Greiner to install it! No complaints!
Christian was a pleasure to work with. Friendly and explained everything thoroughly. He answered all my questions wirlthout rushing through everything.
The back office was very responsive and friendly. My technician was Jason and he came exactly during the scheduled time frame. He went above and beyond and never lost his smile the whole time. He was very professional and didn’t miss details as to double check and made sure everything was working before he left. I was happy with them and subscribed for the membership program.
My service person (Carlos) was extremely knowledgable and helpful in determining the needed cleaning of my unit, and resulting installation if I-Wave. High marks all around.
