I highly recommend Kliemann Brothers Heating & Air Conditioning. They are so friendly, offer excellent customer service & not to mention quick expertise installations! The heatpump/mini split routine maintenance I had done was handled with care! Thanks guys for all the hard work you do with a smile!

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.

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

I was happy with the sales person, the technician, and the heat pump unit that was installed at our place. Would strongly recommend Kliemann Brothers to anyone looking to install a heat pump.

Carter performed an annual inspection and filter clean. He was fast, friendly, and professional. He also reset the wi-fi receivers on a couple of units. Highly recommended!

Cameron Brower informed us if his arrival time. He quickly got his tools and the new replacement control board into the attic. After installing the new board he checked out the HVAC system operation at the heat exchanger and 3 thermostats. He checked the gas furnaces operation and did a checkout of the heat pump. After cleaning up the area, he did a maintenance checkout on our basement furnace. Cameron was friendly and answered all my questions. Thanks to Kliemann Brothers for quickly getting my AC working again!
