Everyone that I have ever came into contact with there has been helpful and wonderful! I would recommend them to anyone! Aaron WilhelmJuly 19, 2024Trustindex verifies that the original source of the review is Google. Gave me a quote to replace my 29 year old air conditioner.They weren’t the cheapest but were priced with in reason. Installed it quickly and operates wonderfully. I couldn’t be happier. Lisa FarrellJuly 19, 2024Trustindex verifies that the original source of the review is Google. My husband and I received 5 quotes from 5 different companies before finally deciding upon Thielmann. Although Thielmann was a bit more expensive, the quality we received was outstanding. We went through the Costco Program (Lesa at Menomonee Falls) and received more rebates in doing so. With that program, we received 10% back on our Lennox Air Conditioner and Lennox Furnace. In addition, we received another 2% back by going through Costco and another 2% back by putting it on the Costco Visa card. At any rate, from, Jason, who came to our house to explain what would be done and provide the estimate, to the installers, Ben and Hayden, who provided excellent care installing our new products. They spent the entire day replacing our new HVAC system. The guys were extremely professional and had great precision. Thank you, Thielmann, for a wonderful HVAC system, great customer service, and an amazing job! Dave SeefeldtJuly 19, 2024Trustindex verifies that the original source of the review is Google. Professional and fast! Installation looks great! De'Angelo TatumJuly 15, 2024Trustindex verifies that the original source of the review is Google. I liked my experience with them. The guys I spoke with prior to doing the work, the estimation phase , and the ones I spoke with after the work was completed had enough knowledge and suggestion to answer all my questions. I’m pleased with the job they did. I had two AC units installed. Jay OrcholskiJuly 14, 2024Trustindex verifies that the original source of the review is Google.
