What Our Customers
Have to Say

“Hello to these three fabulous dependable Siemer workers John, Kraig and Tony for their wonderful job they did on Friday December 6 at my house. I am giving them 5 out of 5 stars for installing my new furnace and air conditioner. For Mr. Paul Siemer, you have great employees in your company. A very satisfied customer! Sending you all a very Merry Christmas and Happy New Year! Thank you againfor the job well done!”
- Marilou D.

“I recommend Siemer Heating and Cooling 10/10. The sales team were helpful with the info and recommendations they presented. I needed to replace my broken furnace and very old AC, a sadly very expensive investment, but I was glad to find they spoke plainly and informatively without pushing me into a particular decision. In addition, every person on the installation team was pleasant and easy to deal with. They were courteous while here, and cleaned up perfectly afterwards- in fact, the installation area looked better than when they arrived. Even after a long day of work in my house, the worker who gave me a rundown of the new system was patient and very informative. I am grateful for their service and would recommend this company to anyone.”
