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.

Review of Grenz Service Company, LLC

Jim was at my house in 30 minutes after my call. Very knowledgeable, totally professional, and resolved my problem immediately. Even made two additional checks to insure my system was up and running correctly. No question who I’d call if I ever have HVAC problems in the future.

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!
