Carlos Manrique was an excellent service tech for Siemer Heating and Vooling
*** 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. Very happy with the job- done very quickly and professionally. My thanks to Siemer and to their Technician Jack. ***…
We've been with Siemer for a few years & have been very satisfied with them. It's easy to schedule appointments & the technicians are on time & professional.

Chris did a great job of servicing our Carrier A/C. Summer time check up. He’s very thorough, informative and takes his time to explain and do things correctly. Great job Chris. Thank you.
Your technician, Carlos, did an A-1 Excellent job both up in the attic on the air mover equipment, but also on the outside compressor unit. His work was efficient, quick, and accurate. As an aircraft mechanic, I know what is good, better, best. Carlos is the best!
Couldn't be happier.
Very polite and knowledgeable.
Alejandro was prompt, put booties on and kept me informed on what was going on. He did a great job and was very personable!

Anthony was very thorough with his service and then explained everything he had done and why. He also came back in to tell me what filter to use and why. I was very pleased with him.
All staff is helpful and very professional. They've helped me and all my extended family in an emergency.
This young man is excellent. Many technicians are so cold no assurance. Jake is friendly and assuring. His work is excellent. I specifically asked for him.
Jake was very professional and helpful!! We have used Siemer for many years!!!
The service man, Carlos, was efficient, courteous, on time, personable. Thank you for him!
I request Carlos because he does an excellent job! He's very knowledgeable about everything. Whatever is going on with my heating or cooling systems, he knows how to deal with it, also very polite and spends the time he needs to working explaining to me. He gets 5 stars from me! I request Carlos each time. Very good technician! - 10-23-23.
Chris did a great job. He was very nice and professional, and explained thoroughly what he did for the furnace tune up. Definitely will use them again.
The technician was very polite. I appreciated the fact that his cell phone number came across with "seimer technician".
Yearly heater check up from Siemer was seem less as usual. Christian was on time, very professional, and communicated well. Happy to be a member at Siemer and ensure my family stays warm each winter and cool each summer.
Friendly and prompt.
Siemers has been servecing 15 HVAC unit, 3 ductless unit plus 24 suspended heaters for my business. They have the best technicians in the area and response time is great. In the past, I used other hvac companies just to explore what else is outthere and find myself going back to Siemers.
I used Siemer Heating & Cooling to do a seasonal check of my air conditioning system. The technician was on-time and professional. I think he did a good job answering my questions and servicing the system. I will use Siemer again for my HVAC needs.
The technician was very professional, on time and worked very efficiently, he also was very willing to share knowledge and help with any problems
Very professional and informative thank you
