Paul was very helpful when figuring out what I really needed to make my home more comfortable.

We had a new HVAC system installed by Siemer Heating & Cooling and were very impressed. From the professional sales rep to the courteous and efficient installation crew, every step was seamless.

Couldn't have been happier with my Siemer experience. From sales call to installation the whole process was seamless, satisfying, and professional. If you need a repair or replacement there's no hotter, cooler place to call than a family managed business who cares about It's customers -Siemer. Special thanks to Wes,…
From my first contact with Chrissy in the office until the installation was complete by Trey (and his coWorker-I’m sorry I don’t remember his name), including the service call by Phil and the sales rep Paul, I could not be happier. They were ALL very kind, polite, professional and honest!!! This is my third…

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.
Replaced my 20+ year central air with a new one 10 July 2023. Everyone was very professional. 11 July 2023, it appeared the fan wasn't working correctly. I called that evening, and Jake S. was at my door 6 am (we had coordinated the previous evening) to troubleshoot. About as good as it gets and a tremendous plus for the Siemer team.
3rd review! Had Jake back for a tuneup!!! He was on the dot prompt, knows his stuff, and is just a super nice guy. I appreciate that he takes the time to explain things and never talks down to you. Thanks again Jake! 2nd review! Had a tune up... technician was Jake and he was AWESOME!!!! He really took the time…

Siemer Heating & Cooling is a comprehensive, first-rate operation.

Jake Dandage was excellent in getting everything done and explaining everything, its use, best practices, etc.
Called out on a Saturday (after hours) to help get our air running again. Phill came out very quick. He was phenomenal. Got our air working again, it was short lived due to age and just needing to be replaced. He was informative, honest and not pushy. We had an estimate sent over and also got two other estimates.…
Excellent service. Abel, Tony & Billy went over & above in every aspect of our installation. Paul was very detailed in presenting our estimate. Would not hesitate to recommend Siemer!
Trustworthy. Great tech
Prompt, professional and friendly.
Had entire AC system replaced. Outside unit and Air Handler in attic. The attic unit they replaced was 50 yrs. old and the crew had to work in very cramped quarters going up ladder thru a pantry. The attic needed a lot of remodeling to fit a new air handler. Jo b was done with no problem for me, but they had…
We had an excellent experience working with Siemer Heating and Cooling in September, 2021. We got several proposals from different installers and several different HVAC providers (Carrier, Lennox, Amana, etc) and Siemer had the best combination of a good product, price, knowledge and focus on our HVAC needs, and…
Requested several local business quotes and Paul Vezmar at Siemer Heating & Cooling was the best! He was professional and had a strong knowledge of his products and what we needed. He didn't try to oversell us like others did. He was honest and patient with our questions and was able to take care of what we wanted.…
Siemer was very quick to respond to an estimate and installed my new a/c and furnace the next day. The installation team was very professional and knowledgeable. If you're looking for an honest, family owned company, look no further and call Siemer!
Siemer Heating is awesome. I’m a repeat customer, and I will always use them. There staff, prompt service, just a genuine company. You won’t be disappointed, I guarantee it. Thanks again for your help today.
Siemer HVAC went above and beyond for me to get the air conditioner quoted and installed quickly. They had the best customer service too. The guys that installed the A/C were very professional and also did an excellent job. Thank you all so much for showing me that there are still great 5 star companies out there.
Siemer is our go-to. Anytime something pops up, they’re prompt, professional, and effective. This past weekend we had a tech over to replace an igniter. He went above and beyond to diagnose the problem and ensure we wouldn’t have any additional issues in the near future based on what he saw and did. Highly recommend!!
