Great Service




Review of Grenz Service Company, LLC

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.

True Professionals




Review of Grenz Service Company, LLC

Great customer service and professionalism. Always arrive on schedule. Each tech was very polite, friendly and knowledgeable. Very respectful by covering their feet when moving in and out of our house. The furnace area was left spotless when they were finished. When the project was complete, each tech thanked me for our hospitality and for our business. I will use this as an example in my own business.


Came right away




Review of Grenz Service Company, LLC

Grenz service was great! Jim was able to come out to our house within a week to fix our gas fireplace that had been out of commission for over two years. We originally got a quote for a two month wait from another company, but his fast and great service meant we could surprise our Father with a newly fixed fireplace for his birthday! He checked the light switch to see that the fireplace was not communicating and fixed that and also had special technology to detect the mixture of gas and air so the pilot light would light. Above and beyond, he even cleaned the glass pane and vacuumed the individual parts to make it look new. Additionally, he was able to answer questions and give tips for future problem solving. Very helpful, highly recommend!


Great service




Review of Grenz Service Company, LLC

Super Service!




Review of Grenz Service Company, LLC

Grenz Service has been our furnace and air conditioner repair provider for several years. Yesterday, Grenz Service installed 2 furnaces and an air conditioner for us. They arrived on time and worked without a break until the installation was complete, several hours later. The team took great care with their work and provided us with progress reports during the day. When the systems were installed, we were given a tutorial by Jim Grenz regarding their operation. We are very happy with the work Grenz Service provided. and highly recommend them to anyone who is in need of furnace or air conditioner service or replacement.


Great service and very informative about the furnace.
