Installed an all house generator. All personnel were great! Work performed exactly as they said it would be. Reviewed everything before leaving the site. Thorough clean up! And a promise to return to check on landscaping. Would highly recommend!

First off thank you for coming out to my property, we called other companies with no response what so ever. When Paul came out for the initial assessment he was great at informing me that the work that needed to be done was a lot and needed another assessment from his boss. Chris immediately came out and assessed all the work that needed to be done and got the fair estimate back to me in a timely manner.
When Scott and Adam came out, they quickly got all my plumbing issues resolved outside and inside my house. It was no easy feat, but Scott did an great job on updating the old plumbing and fixing all the mistakes from previous plumbers. He explained everything in detail to me and was very courteous and professional. Thank you to Zimmermans for supporting your local veterans and doing the fantastic labor in the most professional and timely manner, with a fair price. I will recommend you to everyone and will use your company for all my work!

We recently contracted with Zimmerman Plumbing Heating and Air Conditioning for home duct cleaning and replacement of our hot water heater, furnace and air conditioner. This job was scheduled for a three day timeframe. The work was completed on time to our total satisfaction. The workers are outstanding and their attention to detail is top of the line. The entire process was absolutely seamless to us as homeowners. We could not be happier with the end product and we would absolutely recommend Zimmerman's to everyone.

Hired Zimmerman's Plumbing to do a basement rough in for a bar and powder room. I am very particular person when it comes to details. All the work was completed in one day with the detail that I can appreciate. The job site was left as clean as it was when they started. I would recommend Zimmerman's Plumbing and Heating to anyone.
