  We lost cooling after we had already scheduled an appointment for another issue. I was very pleased with the time frame they arrived and the friendly, yet professional experience with their service person. He was able to determine the problem and get our air restored quickly. In addition, I found their charges to be reasonable for the work involved. I would recommend them very highly.

  I was super impressed in the service and the outcome of the repair. The 2 engineers, Chris and Jim were on time for appointment and immediately diagnosed the issue. They suggested taking the PTAC unit back to the shop to repair and go through the entire system and delivered back this morning. Highly recommend this company for all your HVAC needs. Great job!!

  Recently needed ac service on our old and heavily used unit. Koesterer responded quickly to online request and came out the next day. The technician was professional and friendly. He did just what he needed to do and did try to "upsell ", which was very nice. Overall a great experience. AC is working fine now and the cost was reasonable. I definitely recommend Koesterer for any hearing/cooling needs.
