I was very pleased with Grenz Service. Jim quickly diagnosed the problem with my furnace and was able to get the needed parts and complete the repair the same day. He explained how my system works and politely answered all of my questions. I will not hesitate to call Grenz in the future.
Worked on our gas fireplace to ensure that it was in good working shape. Cleaned the glass and added a monitor (?) to the fan so it is now very quiet. On time, friendly and excellent work.
We just had a full heating and air system installed by Grenz Services recently. This company and the individuals involved were very knowledgeable and highly professional as they arrived on time and completed all work in a timely and very impressive manner. They also were very helpful and friendly throughout. Our new system is working beautifully just in time for this very cold December. We recommend highly!
