Karl Lohndorf GM

Karl Lohndorf, GM

I have been with MacKenzie’s for over 20-years and have a tremendous amount of experience and knowledge in the HVAC industry. Outside of work, you will commonly find me jogging or in front of a TV watching a Netflix series.

Brent MacKenzie

Brent MacKenzie
Sales/Account Manager

Being a MacKenzie is an honor and I pride myself every day in providing exceptional customer service to all customers and prospective customers. I currently reside in Derry with my wife, Laura; two beautiful children – Layla/Luka and my dog, Lily (Yellow Lab). Outside of work, I’m a huge sports fan and love to both watch and play, specifically, basketball, football and wrestling. Hitting the gym is another thing I do on my spare time and of course, spending as much time as possible with my family.
