All reviews for Kliemann Brothers Heating & Air Conditioning

Zach is first class. Great communication to keep me updated on his eta then diagnosed the issues quickly and, realizing we would be without heat for a few days over New Year holiday, worked to get us a temporary fix until parts could be delivered. All round excellent service

From initial visit to discuss install, through maintenance, the service providers have been very professional, well informed and educational. Never lax nor pushy to upsell, just good old fashioned customer service. Would highly recommend them.

I've been using Kliemann for a few years now and I can say they are great! Technicians are always friendly, answer any questions I have and explain everything they will do.

Incredible service! Josh P cleaned our gas furnace flame sensor and got our system back to normal for the rest of the winter. Quick and accurate diagnostics and explained everything thoroughly!

Nathan did a great job evaluating my mini split that began having unexpected issues. He was on time, respectful and very caring for our property. Highly recommended!!!

I’ve been a loyal Klieman customer for 20 years now. Although the original members who started the company have retired, it’s been left in good hands. All through the years I could depend on Klieman for totally efficient work, and they have always been honest in their dealings with me and I’m sure all of their customers.

I awakened this morning to a cold house and dead furnace, I will be going to bed tonight in warm house with properly running furnace. Josh P. arrived ready to work. He listened to my history of the 2 year old furnace and the installer that does not stand behind his work, the repair guy from last year that "fixed" some install issues, the repair guy that was here recently hoping to charge me $7,000 to fix what the installer and first fixer had forgotten to do, but he would not warrant his work. Josh conducted a complete diagnostic of the system, found the installer error, the fixers error and carefully explained the what and why of the repair. For future HVAC and electrical repairs and enhancements Kliemann Brothers will be my first call and Josh will be my first request.

OUTSTANDING IN EVERY WAY!!
I normally don’t write reviews, but when you come across a company that is simply outstanding in every way, I felt I just needed to. Kliemann Brothers HVAC has been incredible from start to finish. From the start with Stephanie R coming out and explaining all of our options in a clear and no-pressure way, to Jeremy’s outstanding professionalism in the installation, explaining everything as he went along and answering any questions we had, to Nathan’s expertise in making the final touch-up’s, to Hannah and the amazing office/answering staff who have always made us feel like we are an appreciated and valued customer, rather than just a sale, these folks are the best company I have ever had the privilege of working with. Bottom line and in my opinion, if you want an HVAC company and service that is affordable, professional and reliable, hands-down, Kliemann Brothers HVAC is the absolute BEST OF THE BEST!!!

Cole and Jaden and Team Kliemann Brothers excelled from start to finish. Estimator Athena was prepared and knowledgeable and communicated well. Our install was orderly and organized and we could not be more thrilled to have our old electric furnace replaced with our new whole house heat pump. Highly recommend!!!

!0/2025 Yearly maintenance:
I want to add to my previous recommendations regarding Kliemann Bros. Maria is a total professional when she arrives and gets right to task. Extremely professional, discusses with me the work she has done and suggestions for the next maitenance visit. I am confident in her work. I am lucky to have her as the technician who maintains both my heat pump and on demand hot water systems. Kliemann Bros. is a great company to work with.

Update 09/09/2025:
Well you know how great a company is when you have an urgent/emergent situation and they respond without breaking a sweat. My tankless water heater developed a substantial leak and Nathan was the first technician to arrive. He quickly accessed and diagnosed the problem, called Matt the service manager, and they came up with a plan to have Sean, another technician, with the appropriate equipment and parts to stop over and fix it. Sean did an awesome job.Sean went about his duties with a quite professionalism and was able to stop the leak with no problem. Both technicians did a stellar job and gave me the confidence that the job would be completed without a problem.... Thank you Kliemann Brothers for having great staff who are extremely capable of getting the job finished.

Update 05/15/2025: As I have stated in my previous reviews, I am so happy with Maria from Kliemann Bros. Maria is a consumate professional. Always calm, goes about the work in a proficient, experienced manner. Maria worked with Elliot today and they serviced the heat pump and on demand hot water heater. Both performed the duities as expected. Thank you for having such dedicated employees who set my mind at ease regarding my heat pump and hot water heater. Kleimann Bros is my choice for furnace and hot water heater work.

Update 11/27/24: I am always pleased with Maria from Kliemann Bros. She is professional and goes about the work in an efficient manner. She was working with Chuck today and they were the perfect team. Fast job on my maintenance and off they went. I will always recommend Kliemann Bros for their great work staff who never steer me wrong.

Maria P from Kliemann Brothers was the technician who did the check on both my on-demand hot water heater and my furnace/heat pump. Maria was a total professional. She got right to work, very efficient and quiet Maria answered questions to my satisfaction. I have requested Maria for all my follow up appointments if possible. Thanks for being a business I not only recommend but trust.

Our diagnostic service technician Nathan was professional, on time, and able to relay information in a way that was easily understood. He dialed in our new system and we appreciate the whole team for setting us up for success!

Zach arrived on time and was friendly and professional. He explained what the system needs abd what associated costs there for the visit. He also made suggestions for further care. He was honest. Someone had turned off the pump and he showed us how to turn it back on. He also explained that maintenance is needed since it is 20+ years old. Kliemann Brothers installed the system 20+ years ago and I highly recommend them.

Zach did a great job, showing us what he was doing and explaining how some things work so that we understand ‘why’ maintenance is so beneficial. Zach gave us some good ideas on improvements that fit “US”. Really great experience today!

So our '50s oil furnace needed a service. Filters and nozzles and all that. A guy from a different company came and did that, and immediately after he left, the furnace started blowing diesel fumes all throughout the house. Didn't have heat for a week. So called 10 other companies before Kliemann said that they actually do service old oil furnace. THANK GOD. So they sent a great lady named Maria out to help me us. She was able to take it apart, thoroughly inspect it, diagnose the issue, realize that normal tactics weren't going to work and tried something new as a last ditch effort. And it worked! She was amazing and we cant thank her enough. If you got an old diesel chugging furnace like I do, definitely give this place a call. They won't disappoint.

Our furnace went out on a Sunday. We were able to get an assessment on Monday morning and the repair on Tuesday. I’m so satisfied with how quick and kind the service was preformed! I will definitely call again with any needs for my home.

Installed with them years ago, and continue to use them over the years. Their technicians are very knowledgeable and personable. They take the time to explain things and are very thorough in their work. I can't recommend them enough.

I'm not sure if today's work is considered maintenance or repair, but this is the 2nd time I've had the pleasure of working with Zach. The first time was finding the problem after a flood in my bathroom caused water to get into my ducting, which in turn caused the crossover duct to be damaged. Once he was able to identify the problem, the duct was ordered, and he was able to make the repair today. Zach is pleasant and knowledgeable; he definitely deserves recognition. Thank you, Kliemann Brothers for Zach and all the others who represent your company.

The tech, Zac, arrived the same day that I called the office. He was courteous, professional and thorough. He was friendly but stayed on the task. He diagnosed the problem quickly but went further and tested the system components for short circuits. He answered all my questions and even fixed a failed seal around the vent pipe of an adjacent furnace. We are very happy with the service we received from the moment I called to the finished product.

Everyone we dealt with starting with Ben in Sales, Hannah in the office and then Jason performing our install. They were friendly, understanding of a stressful situation for us, courteous and professional. We were very impressed and thankful. Daniel came out to make some final adjustments and did a great job. Very knowledgeable and friendly to deal with

Excellent customer service. Quick response time. Colin was very diligent and professional. Our system took extensive troubleshooting, and he was able to get our heat pump back up and running. He took the extra time to find a solution that other companies had not done for us. Wish we would have called them sooner!

I would more than recommend Kliemann Brothers. My furnace went down on a very cold new years day and they came out and fixed it and restored heat to my home for my me and my family. Josh the technician was the best. He was very knowledgeable and a really nice guy. If I could give more than 5 stars I would.
