Great Service




Review of Grenz Service Company, LLC

Grenz Services identified issues with our furnace while conducting seasonal service checks and cleaning. They also identified a leak in our air conditioning system during the same visit. The technician helped setup a system review for the Spring of 2021. Grenz Services conducted an in home review of our heating and cooling needs and offered two options for us to choose from. Each option was explained in detail helping us to make an informed decision for our needs. They setup the installation and removal of the old system. The crew left our house cleaner than when they began the work. They were in and out in about 5.5 hours. I will recommend them to anyone that I know is looking for HVAC work.

Great service




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!

Outstanding service. Quick response to fix my AC




Review of Grenz Service Company, LLC

Jim does a great job of explaining the problem and offering solutions to fix the problem. I can trust 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.
