- TOTricia Orzel3 days ago5.0I was prepared to get several estimates. I met with Rudy regarding options and he was so good and helpful. I made the decision to trust him. They were efficient in their work. I don’t have any photos.
- DDDeb David5 days ago5.0James & his teammate replaced my furnace today. They arrived on time & quickly got set up to get the job done. I could tell they were experienced with this unique furnace & air conditioner unit. The two worked very well together & got the unit replaced quicker than I expected. These were were skilled, efficient, respectful of my home & cleaned up well when they were done. They even checked out my gas fireplace to be sure it worked as the gas had been shut off. In addition they saw an additional area of concern with existing tube & quickly fixed that too! I enjoyed the conversation which further made me trust in their skill set. Great job Thielmann on employing these two!
- SESusan EgglestonAug 17, 20265.0Benjamin is very knowledgeable and professional, answered all our questions regarding our new A/C and furnace operations and maintenance. He also cleaned up/took all garbage with him.
- GTGuy TuxhornAug 14, 20265.0Donovan was requested to perform heating and air conditioning tune up. Our system did not have any problems, but we missed the system tune up last year. Donovan met me at the driveway, introduced himself and proceeded to ask if there were any problems. With that, he proceeded to service our units, told me of the services he performed and did not find any problems. He did inform me that the system is 10-11 years old. I had no clue it had been that long since the original installation. Donovan is a fantastic service technician and I would request him again.
