Testimonials

On 5/28/2025 J Laskowski had this to say:
Our A/C unit would not start. We discovered it late on a Friday afternoon. We called Mavec and scheduled a service call. John showed up earlier than the scheduled time, diagnosed the problems and had the job completed within an hour. This is the second time we have called Mavec and could not have been more pleased. Professional, extremely knowledgeable, courteous and friendly. Highly recommend Mavec.

On 5/12/2025 Tanya and Brad Anderson had this to say:
HUGE thank you to John Mavec!! We were told by another company we needed a new compressor and lots more $$ and John came out and took a look and had it all worked out quickly! He was helpful, honest, and fair. We will definitely use him in the future! Testimonial written by Tanya and Brad Anderson on this site.

On 5/9/2025 Pamela Jaeger had this to say:
John Mavec just saved us a LOT of money! 😃 We thought for sure, at the end of last season, that we would need an entire new AC system this spring. Not so! John Mavec came out today and changed out our thermostat and a part on the exterior AC unit and that was that! We have cool air for just a few hundred dollars, versus several thousand!! Before throwing in the towel on your AC, give John Mavec a call. He's been in this business for a long time and knows his stuff. (Thanks for making us cool, John, and saving us BIG bucks at the same time!🌟🌟🌟🌟🌟)
