We have been doing business with Nimmer Heating and cooling for over 25 years and have never been disappointed. They are a honest and trustworthy company. Today Mike Kurth came out because our furnace was not working- within minutes he knew what the problem was and helped us make an informed decision after checking for warranties and parts. Mike was very knowledgeable and explained all our options. A very stressful situation became easy and not so stressful with Mike helping us to make the right decision and saving us money. Thank you Nimmer and Mike Kurth!

Blake and Matt were courteous and capable. I highly recommend them and Nimmer. As a caveat, I had West Allis heating do some work year's ago, they actually lied about what they did. Nimmer is my go to HVAC company from now on.

Nimmer Heating & Air Conditioning was recommended to me by my neighbors after receiving their service for years. When I called, Beth was friendly and helpful on the phone for scheduling. I had annual service performed on my furnace by Joe, who is clearly very knowledgeable. He was professional, provided education regarding my furnace, and answered my questions. Nimmer will be my go to company for my heating and cooling needs going forward.

Nimmer has been our heating and cooling company for years. They came to install our New HVAC system and Thermostat. Pat, Josh and Ryan were very professional and did a great job. They answered all my questions, walked me through the new thermostat, arrived on time and finished earlier then expected. I highly recommend Nimmer Heating for all your Heating and cooling needs.

Provided excellent service. Was able to fix our furnace within 24 hours. The technicians Blake and Mathew were great at explaining the issue and getting the part replaced in a timely matter. I also appreciated the efforts of Beth to get us the part so quickly and through the warranty. I highly recommend Nimmer.

Beth was the best dispatcher I’ve ever talked to! She was the most personable, thorough, and helpful person I’ve talked to in a long time. Our technician Mike was fantastic as well. He made me feel like an expert and explained how he fixed our heating issue. He even faced a challenge outside with his window of his truck, and handled things very professionally. 2nd time I’ve had you guys out for service (different homes) and I’ll never call anyone else. Thank you!

We recently used Nimmer for a new furnace & AC install and they were fantastic!! Malinda was great and had great communication throughout the process. I had to reschedule my install date due to a WE energies delay, and Nimmer was extremely accommodating. The install went seamless with no issues. Pat was wonderful and showed us how to use the new thermostat and explained what he did in the basement for the install. Would absolutely use Nimmer again! 10/10 recommended! Wonderful business and employees!

Nimmer has been one of the best companies we've ever had to do work for us. I can't say enough on how quick, reasonable, professional and workable they are! We had a new boiler system put in and Pat and Josh were so courteous and quick! They double checked our system before leaving and never made mess anywhere in my house. I vote 10 stars out of 5. I would highly recommend Nimmer.

We have used Nimmer on two occasions. It has been wonderful to use this company! We’ve spoken to Beth on the phone who has been incredibly helpful, professional, and sweet. She is very personable and was able to get Joe D. to our house within a few hours on a day when our air-conditioning stopped working. Joe was very knowledgeable. He took the time to explain a lot of the details of what was going on with our system. Joe came back again to install a smart thermostat for us and tuneup our furnace. I have really appreciated his thorough work and his professionalism. I would highly recommend Nimmer.
