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.
Jim has a great disposition. always friendly. does his evaluation,tells you about how it will cost, then goes to work & gets it done. never tries to sale you anything you don't need.good about answering any questions one might have..............
Junior can be counted upon to be immediately in response and promptly replying. Cogent and quickly assessing the issue. He nails it!
Great people to work with. They explain what’s going on and give you a price for parts and service.
I was very satisfied with James promptness and repairs
Excellent service as always
Great diagnostic and repair work in a very short and precise time limit
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.
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!
We have been so pleased with Grenz Service! They are always so prompt when we call for service and their prices are very fair. Jim is honest, fair, and a great help! I would highly recommend Grenz Service.
I've used this company numerous times and have never been disappointed or overcharged....something that rarely happens any more. I very highly recommend them.
Very happy with the service!
We have an older fireplace that other companies would not look at. Jim is very knowledgeable. He fixed various issues including a gas leak. Highly recommended.
Knowledgeable, efficient, affordable and very helpful!
Great work, love the explanation of what is being done and why. They are super thorough and give great advice about how to make the units last longer, work more efficiently, etc. They are kind, efficient, on time, hard working, and easy to work with!
Very responsive and great service
I have used Grenz Services since 2006. Very reliable, excellent, knowledgeable and fast work at reasonable prices. Jim is always polite and courteous. Highly recommend!
Undercounter fridge making a constant unacceptable noise for staff and customers . They came literally in 20 mins, informative and professional work.
I really like this service. They come soon after called, always timely and do good work, explaining what they do.
Easy to talk with and to understand
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.
Very friendly and professional.
Have used Grenz for years and they are always quick and reliable when I need them, no matter what are problem. Also, always leave the place as they found it...clean!
Had a problem with A/C mid Saturday AM, Memorial weekend. High temps with higher humidity outdoors. Grenz called back within an hour or 2, was at our home 3 hrs later to make repairs. WOW!!! What service!!!
This is the second time that I have needed Grenz Service for furnace repair. In both instances, I’ve been highly impressed with the response time and completion time to get my furnace working properly. I will absolutely call on them when future needs arise.
