Review of Grenz Service Company, LLC

My AC unit stopped working on a Friday morning. Jim was able to come out within a couple of hours that afternoon. He was very knowledgeable and knew right away what the problem was. I appreciated that he explained to me what was wrong. I have Grenz scheduled for general maintenance coming up and know I’ve got a great company coming.

Excellent service




Review of Grenz Service Company, LLC

Grenz crew arrived exactly on time to install a furnace. They estimated that total installation time would have them leaving the site by 2pm. However, every thing went well and they were finished up by 12:30pm.

Top Notch Company!




Review of Grenz Service Company, LLC

We needed both central air and furnace unit. Jim came out to our home to meet with us and provided a very thorough and comprehensive explanation of his products and services. He inspected our home and gave us several options. I have NEVER met an individual so thoroughly knowledgable about the industry, their product line, and technical details. Outstanding person to work with. Very professional communication - and timely! They reminded us of their upcoming visit and provided detailed receipts. (Nothing hand-drawn here!). The install was flawless - professional and hard-working team. I sincerely wish I experienced this degree of professionalism, honesty, and expertise with each company we worked with. We are very grateful we found Jim and his team. They are now our HVAC company and we would highly recommend them to everyone. Thank you Jim!

This is the way companies should do business




Review of Grenz Service Company, LLC

Jim and his crew were outstanding in every aspect. On time, professional, polite, and committed to detail and customer satisfaction. After receiving and reviewing quotes, I knew Jim was the man for the job. When he put the quote together, he sent it to my email immediately for review and it was totally detailed. Remember to always, always, always get any oral agreements put in writing. We worked out an agreement on an additional item, and Jim revised the quote within minutes of hanging up with me. His labor agreement was 4 years as opposed to the standard 1 year with other companies. Looking forward to many trouble free years with our new American Standard AC unit. Choose Jim; you will be glad you did.


Great service, quick response




Review of Grenz Service Company, LLC


EXCELLENT SERVICE AND INSTALLATION!!!




Review of Grenz Service Company, LLC


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.


On Time Great service and personality
