  • Thank you so much!
    I requested a service and inspection from Zimmermann AC and Heating 3/23 and Omar arrived promptly and took care of it quickly and professionally. My husband stated that our AC hasn’t worked this well since we purchased the home. He was very pleased with the service. Thank you so much!

  • My entire experience with Zimmerman has been excellent from the beginning.
    My entire experience with Zimmerman has been excellent from the beginning. Vanessa, James, Melissa—each one is kind, professional and patient! I received a call before James arrived, confirming the time—and he was on time! He was very thorough and explained everything so I could understand what he was talking about. The recommendations were sorted by what was really needed and what could wait for later. James was careful to explain why the recommendations were being made as well. I am so pleased with Zimmerman. I highly recommend this company without reservation.

    Zimmermann has taken care of me for decades. They’re like family. Very knowledgeable and courteous. Highly recommend!

    As an update: Peter came out to the house today when I noticed my AC wasn’t cooling properly overnight. He had an idea of what the issue was based on my explanation and he was correct! Was able to repair and the house feels so much better. Very knowledgeable and a lot of fun to talk to! Thank you Peter!

  • I'm confident that I'll be working with this company for years to come.
    Recently needed a new unit and new duct work done. Had the pleasure of meeting James who has been from day 1 very polite and professional. The crew that came to the house were also very good. They showed up on time and were quick to work. I can't think of any negatives to point at. And the company has been responsive with help even after installation. With that being said if you're in the market for a new unit or duct work. The Zimmerman Company does deserve the chance to come by to your home and sit with you to help with you ac needs. Will update review in the future if anything ever changes. But I'm confident that I'll be working with this company for years to come.

  • Zimmermann has been great to us...
    Zimmermann has been great to us & we enjoy working with the serviceman Omar, as well as the receptionist, Amy. They are friendly, punctual, honest, and well-priced. They take good care of us, making suggestions that are in our best interest not just for their profit. And I love that they are a local family run business!

  • I recommend this company.
    Zimmerman has provided excellent services since they have serviced my units. We have dealt with one technician in particular. He is trustworthy, punctual, provides an excellent explanation of services rendered and any additional services required. Omar is an excellent knowledgeable technician you can trust. I recommend this company.

  • Fast, friendly service!
    Needed our heat pump serviced, they sent a tech out the same day. Fast, friendly service! Peter, the technician, explained the details of what he was doing on the unit. A very knowledgeable young man, He did a great job!

  • I recommend them highly!
    I have used Zimmerman exclusively for several years and they have always been very responsive and great to work with. Recently, when my AC wouldn't turn on, I called Zimmerman on a Saturday night and they had a repair person at my house at 8:00 the next morning (Sunday) to fix it.
    Luke and Terry feel like old friends and I trust them completely. I recommend them highly!

  • I recommend Zimmermann A/C and Heating for your HVAC needs.
    Zimmerman A/C and Heating replaced two complete AC and Heating units in our home. From the estimate to the follow up they were very professional. No excuses just promises made and kept. The work crew was organized and professional. The job was estimated correctly so all the parts, tools and equipment were on-site when needed. The team was done with two units in two days. Very pleased with their work as well as the new units.

    Supervisor Terry did the initial walk through estimate as well as the final inspection and follow up. Clean up was done following the work. Woodwork rubbed/nicked during the installation was replaced or repaired. Replaced as in measured, cut, painted and caulked. Very nicely done.

    The support after the sale (parts/labor warranty) were top-notch, too.

    As a member of the IBT I was pleased to see the employees were happy with their work and company. Their level of training and camaraderie were impressive. I recommend Zimmermann A/C and Heating for your HVAC needs.

  • I have used Zimmermann Services for over 30 years and will continue to use them.
    I have used Zimmermann Services for over 30 years and will continue to use them. They are always on time, professional, friendly, and priced right. Today their service rep Peter came to look at our heater. He called before coming and arrived within 15 minutes of the scheduled time. He had our heater up and running very quickly. He was courteous and knowledgeable. Luke Zimmermann has a great company.

  • Zimmerman replaced my AC system last year and they were so professional.
    Zimmerman replaced my AC system last year and they were so professional. Today I had to call them on a Saturday because something wasn't working right. They were out in a couple hours, did a temporary fix to get our house cool again and will be back on Monday to get everything up and running. They are always straightforward and tell me exactly what the problem is/what needs to be done to fix it. I never feel like they are trying to up-sell me and throw me a sales pitch. Super down to earth company that I would recommend again and again.

  • Finally I called Zimmermann and received immediate response and scheduling for the same day.
    I have been searching for an A/C company to check out the outside unit of our home because of a squealing sound. I called a couple companies and had issues with call backs and scheduling. Finally I called Zimmermann and received immediate response and scheduling for the same day.
    Albert was the technician that came out and I couldn't have been more pleased. He was on time  and had a good attitude.  He checked out our system, which is 18 years old, and walked though with me different issues to watch out for and explained things to that could help it out. He never tried pushing a sale or new unit on me, but just wanted to address the actual issue.
    I will continue to use Zimmermann Air Conditioning & Heating in the future and would recommend them to anyone. Thanks Albert!

  • I simply cannot say enough good about the experience..
    Excellent price point.  Service was top notch and really quick.  Completely trustworthy company here.  Technician called with follow ups of location and meeting times.  Technician was on time and actually early.  A job I felt would take more than two hours was done in near 45 minutes.  Every single step was explained, after the repair everything was explained and the technician was really thorough.  Worksite was cleaned up and left better than it was found.  Truly, I could not have asked for a more wholesome transparent and honest experience in an AC repair company.  

    If your having AC troubles your stressed, it's a stressful time but my only regret is that I did not find this company sooner when I needed an honest AC company before.  If you follow my reviews or know me you'll certainly know my AC needs of past times.  Your only regret if you are having AC troubles may just be not giving the company a call.  

    I simply cannot say enough good about the experience while I do not "wish" to have more AC issues I feel better finding business to trust.

  • Got my AC back up and running thanks to Luke and his team.
    Got my AC back up and running thanks to Luke and his team. Your help is appreciated! Fantastic customer care, these guys operated in a way that made me feel at ease and confident.

  • Definitely recommend this company!
    Our house has 2 AC & Heating units and when one went out 6 years ago, Zimmerman replaced it for us.  Luke was very polite, personable and professional.   When we had issues with that unit (minor) over the past 6 years, Luke was always quick to respond and resolve the problem.  
    So when our 2nd unit failed at the beginning of the summer this year, (95+ degrees outside and 135 degrees in the attic where the unit was stored) we decided to use Zimmerman again.   Within days we had a new unit.  We received the same superb customer service as we did 6 years ago and are now happy that both units are being serviced by the same, high quality, family-owned business.   Definitely recommend this company!
