Report
Before choosing Zimmermann I received several quotes. However, after speaking with Trey and the recommendations from friends we knew whom we should choose. I was very impressed with the install crew. They were extremely courteous and respectful of the property. They always made time during the install to answer any questions or concerns I had even though we had quite a complex install. The support I have received after the sale has been excellent. Their team is quick to respond and that has been a load off my mind.

When our A/C suddenly stopped working on a 100 degree day after work we needed after hours help fast. I was lucky to find Zimmerman because in under 1 hour our repairman arrived. We ended up needing a new capacitor which was replaced. Prices were transparent and our repairman was honest about what we needed. No pressure sales. Both the service and our interactions with our repairman were professional, friendly, and very pleasant. We also purchased the service plan and are very happy. Thank you. I definitely recommend their business.

Had a third party come from Best Buy to install new thermostat and they ended up blowing the ac an thermostat. Zimmerman was able to send out the same afternoon, on a Saturday. Omar was very friendly and professional. He diagnosed and fixed the issue quickly. He then spent several minutes explaining the features of our thermostat and preventative maintenance. House was cool and wife was happy. Thank you!

Quick response to an inoperable AC. Scheduled a time for repair and then called with an opening to come well in front of scheduled time because they had an opening. Stevie came for repair. Stevie was knowledgeable, kind, honest and repaired exactly what we needed in under an hour without any crazy upselling I have experienced with other AC companies. Great communication. Reliable. Honest. I am a realtor and have used Zimmerman several times for listings. Will continue to use personally for my own home.

When we realized we needed A/C servicing, we began our footwork. Zimmerman's A/C & Heating did not disappoint. They live up to their stellar reviews! Terry and Trey provided visuals, for all you "This Old House" peeps, like myself, and answered all of our questions. After deciding on the appropriate systems for our home, Michael came out with the installation crew and installed our new systems within a couple of days.
Can't forget to mention Tracey's quick and great office fulfillment with paperwork and scheduling! It's very refreshing to find an honest company that you can trust. Thank you Zimmerman AC & Heating!

Bar none The Best. Just happened to see the Zimmerman van when one of my tenants needed emergency service. In every aspect they took my sense of urgency as serious as if it were their own issue and the responsiveness from the Office folks to the Techs, never waned. The professionalism, communication, attention to detail and right pricing stood out. As a real estate investor experienced with various local companies, Zimmerman is the best. No one else comes close for my properties. Do yourself a favor, you'll be glad you chose Zimmerman AC.
