AC wasn’t working, left message with answering service the night before and by 10am the next morning, Phil was out and identified and fixed the problem quickly. Great work! Thank you!
As usual, Phil was able to locate the problem quickly And have it taken care of in a timely manner
After hours phone was answered by a pleasant human being. Jake, the technician, called right back and came out before sunrise on a holiday weekend. He arrived promptly and within the promised timeframe, fixed the issue, was efficient, informative, honest and had a great attitude. Others say they have 24/7 service,…
*** 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. ***…
This dude Phil Hupke came out and fixed my air conditioner in 10 mins. I was mind blown how fast he was. If you can request him I would strongly suggest it. Today the heat index was around 102 today. I would have been in big trouble. 5 stars all day for this company!
Chris Acosta was amazing. Great customer service with no B.S. recommendations. Would highly recommend Siemer.
Chris gave me excellent professional service, both winter and summer inspections. I am very pleased with Siemer and all of their employees that I deal with.
Alex was grear! On time. Thorough and explained everything that was checked or serviced.
This company is great. They told me what time they were going to be here and they were right on time. Jake was good he did the job 100%. I extremely happy.
Jake was great! Arrived when scheduled. Diagnosed the issues, completed repairs, and returned, again as scheduled and finished the work. Thank you Jake and Seimers!
The technician Phil was amazing. He was kind courteous and he repaired our air conditioner quickly. This was the first time I used this company. I will definitely call them again if I ever have an issue with my heating and cooling needs. I truly appreciate that they called me when they had a cancellation and came sooner. I can't thank them enough.😊
Jake and Carlos are wonderful. Thank you!
Such an amazing experience! The office building I work in had some issues. My bosses originally spoke to a different company and got a second opinion from Siemers. They came out, did the work within a day or so and were so pleasant to have around. They found the issue and took care of it right away! Shout out to…
Jake did a super job of fixing my A/C! It stopped working and he found the part that was damaged and replaced it with a smile! Thanks for being you, Jake!
Always prompt, on time, and does a great job!!! Definitely recommend.
Jake was very professional and helpful!! We have used Siemer for many years!!!
Siemer didn't waste any time getting technician, Chris to come out. It was a holiday and the young man was knowledgeable, prompt, friendly and willing to explain what he was doing. Once he was able to get the AC operational, he stuck around to confirm nothing else was wrong. I will recommend them anytime! Very professional and reasonably priced.
Very professional, made sure that my A.C was still under warranty., and saved me some big $$.
April 2025: Andrew and Wes did a fantastic and quick job of assessing the problem and getting us estimates for a furnace last week. Anthony and John replaced our furnace today and were quick with the install and cleaned up their space of any mess, including the hallway of our condo building. John explained what…
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.
Excellent service on two occasions. They were responsive, scheduled service in a matter of minutes. Professional service along with their work product delivery.
The technician was very polite. I appreciated the fact that his cell phone number came across with "seimer technician".
Our A/C unit stopped working on a Friday night. Siemer sent Carlos Manrique to service the compressor on Saturday. We’ve had Carlos for regular inspection services before and have always found him courteous, informative, and very competent. The compressor’s capacitor was found to have failed. Carlos had it replaced…
John K deserves a raise! He busted his butt putting in a new furnace and AC system in my home today. He is very kind and efficient, so grateful for his hard work!
Re-visiting my original review from lasy year for the drawing to say my AC worked beautifully all summer long and now that we are in winter months my super old furnace is finally giving out so I'm going to call Seimer tomorrow to set up another visit for a consultation for get a new furnace. With all of their…
Just had Carlos come out to clean and check our furnace for the upcoming winter. Very knowledgeable and was a very nice young man. Definitely will have him back in the spring to check our air conditioner before summer hits.
Quick and easy visit from Seimer today. Easy/convenient scheduling, tech on time, solved the problem and got us ready for the upcoming season. Great price too! Seimer is always reliable and efficient.
Team call and made sure we knew what was going on. Sent texts messages throughout the day to keep us inform. Gentlemen arrived when he said, was very professional, recognized the issue immediately and began his work. He was very quick and made sure things were great before leaving. 10/10
I never enjoy leaving bad reviews but feel it is necessary to provide feedback if the company truly values the work they do. I called Seimer to check my AC unit and provide me a quote for a replacement system. I will admit that I knew full well that there was a service visit fee; however when the technician was hear…
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.
The technician was very helpful and informative, Our Church has been in business with this company for years and we wouldn’t change a thing. Thank for you rapid response to our call.
Brendan was great!! Very professional, I will definitely use again and 100% recommend to others!!
We've used them for our old home and new, wouldn't use anyone else. Paul is the most thorough person and will work with your budget to try to get you the best value.
The technician was very professional, on time and worked very efficiently, he also was very willing to share knowledge and help with any problems
The technician was on time, courteous, professional, and discerned the problem almost immediately. He then solved the problem in a matter of minutes. Great service!
The technician, Victor, was on time, and worked efficiently to repair our A/C system. He was very good at explaining what needed to be done. We were very happy with the service that Siemer heating and cooling provided.
Dennis was very professional and efficient completely had knowledge of what he was doing showed up on time and informed me of everything that needed to be done. Excellent job!
The service is great and been using them for the service of my units in my rental building, including my home unit. I will continue to use them.
Jake Sandage did an awesome job and took his time to figure out what was wrong! He is very professional at what he does! Thank you Jake for being 100% with me and being 100% honest I will definitely will recommend you to anyone
Our air conditioning system stopped working on a hot, miserable June day. The intake specialist was very helpful and able to schedule our appointment within 2 days. Victor Zerngast was on time and did an excellent job diagnosing then fixing the multiple issues. I highly recommed Siemer and especially Victor.
