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.
