Great service




Review of Grenz Service Company, LLC

Jim called me back very shortly after I had left a message. He was able to come out to my house the same day. He had been recommended by my son and I too would recommend him. My air conditioning was not working and Jim was able to fix it the same day because he explained that he carries these parts with him so his clients don’t have to wait. Especially in the recent humid days we are having

Great service




Review of Grenz Service Company, LLC

I appreciated how engaging James was during the service call. He showed me in detail how a pressure switch failed which prevented the furnace from going into stage 2 heating. He also showed me what was causing a humidifier leak and how to replace the humidifier filter. Overall, Grenz seemed pretty honest and fair. I'll probably continue using them for future service.

I called for service on my sisters furnace. After leaving a short message I received a return phone call from Jim that he could be there within the hour. He indeed showed up, went right to work and had the issue resolved within a half hour. He had to get the part, installed it, replaced the filter and cleaned up all within a timely manor. Both Jim and his partner were very professional, polite and a pleasure to do business with.
