I have used Mannix for almost 8 years on recommendation from the previous owner of my home. They are always responsive, provide reasonable prices and great services. I especially appreciate their quick response when my air conditioning unexpectedly failed one evening. They quickly diagnosed the issue and had my system operational within an hour after arrival. Thank you!

Emanuel did a fantastic job with our spring HVAC maintenance. He arrived on time, was professional, and explained everything clearly. The system was thoroughly cleaned and tested. We appreciate the attention to detail and great customer service. Highly recommend

I have used this company several times in the past and have recommended them to others. The customer service, the efficiency of the technicians, the professionalism of the sales rep and their reasonable price is literally the best I have experienced and I highly recommend this company. I recently needed a new system and the whole process was unbelievably amazing

Mannix has been very reliable and easy to work with. Recently KP and Emanuel performed a service on our home. They showed up on time, worked efficiently, and completed a minor repair. They were polite and worked independently. I would use them again.

We appreciate KP! He’s patient when asked to explain things twice, polite, takes pics for our review and helps us in any ways he can. We love having him do our checks each season to develop a relationship and feel secure he’s keeping tabs on things over time. It’s great collaborating with earnest people who love helping others. 🌞
