For years our ac froze you in the office and no ac in the master bedroom. Other company quoted $1500 plus to fix it.... Larry from Kenmitz called 30 minutes before arriving and arrived on time. Very professional young man!! He diagnosed the problem , installed several dampers and balanced the entire airflow throughout the house. The ac no longer sounds like a hurricane in the attic and I can sleep in a cool master bedroom. Well done Larry and Kenmitz. Cost was much lower than competitors more

5 stars! Brandon came to my aunts house in Lake forest. She needed a maintenance but after looking through the system... Brandon noticed some things that should be done and explained them very well. Including fixing the copper line covers and adding a unit to help the system perform better! Great job and the system looks brand new. Thanks again!read more
