- JJJoeMar 24, 20264.0I had my furnace and air conditioner replaced by Thiemann heating and cooling. I am satisfied with there work. Brandon G. and Brendan did a good job on the install. They answered all my questions and had a great work ethic. (hard to come by now days). Jason in sales and Maki (probably spelled that wrong) were very polite and helpful. I purchased through Costco. Thielmann handled all the rebate, permits and scheduling. Pretty much no hassle for me. Which relieves a lot of the stress in doing a project like this. I will give them 5 stars after the job is complete. Due to the weather they were not able to completey charge the air conditioner with freon. After that is completed I will definitely upgrade my review!
