Client Testimonial

I used Hamstra to install my heating/cooling years ago when I built a home. I was very impressed with their service then, so naturally called them two weeks ago for a new AC/heat unit. Again, I had a very favorable experience with the company. Every phase went smoothly starting w/ Renee who came out on the initial service call, John R. walking me through the whole process from beginning to the ending walk through, John S. and Mike L. coordinating and doing the installation along with Rick R. the field engineer. Each of these men are very personable, take time to explain what is happening, answer any questions, and work closely with you and each other scheduling the work. I highly recommend Hamstra for their professionalism and exceptional service. June 2020 Shane came out today to perform the yearly service on my AC/heat unit. Inspite of the 106 degree heat, he spent quite awhile on my roof making sure everything was running smoothly and performing the service. Thank you Shane for your diligent work and time.
