Jake did an excellent job with my furnace check up. He was extremely professional and answered all my questions. He helped me navigate my humidifier settings and my air conditioner cover placement. I definitely recommend Jake and Seimer heating and cooling. They are the best.

Tony did a wonderful job! He carefully checked the furnace and pronounced it in perfect condition! He changed the humidifier pad and changed the furnace filter! He also gave me a suggestion for fixing the carbon monoxide issue with my generator! What a great job! Thanks, Tony!

*** Update 8/12/2026 - used the Plumbing Service of Siemer today for the first time. It was an emergency situation. They had a Technician out here very quickly and he assessed and fixed the leak.

The technician called before arriving and was on time. He was helpful with explanations and gave opportunities for questions (and wore shoe protectors while indoors). The friendly service and helpful advice was appreciated.
Great service the technician Alex is a very skillful and knowledgeable young guy extremely professional and very respectful and professional (5⭐️s)
Jake Sandage came out to look at a problem we had with our air conditioner. He was able to fix the problem and spent time with us explaining the best and most efficient way to run the air conditioner when we return it from vacation mode. Jake was very personable and professional. Siemer's is very lucky to have Jake on their staff.
John, Kraig, and Denis did a great job installing a new furnace/AC! They explained everything in terms that we could understand! This company is outstanding, and we love having the maintenance program! Whenever we call, they are here, and that's a great comfort to us. Thanks to Paul and the gals in the office as…
Carlos was great. He came previously to inspecting the heating system now was the AC… look forward to doing another checkup before the winter again. Will recommend for service maintenance and keeping your system maintained and running.
Tech was very courteous and quick.
Alex arrived on time and was very polite. We learned more from him than any other technician who came to check our air conditioner Our furnace/air conditioner is only 3 1/2 years old but we get it serviced every year. Alex answered all our questions. Alex is a very knowledgeable young man.
I would ask for Carlos the next time we need service for our air conditioning
Jake Sandage serviced our central A/C unit today. Very thorough, explained what he was doing and why. Addressed my questions and concerns. An excellent technician...A+++ rating. You won't find better.
