We were in desperate need of a fix on our AC system during the July heatwave. The issue arose on a Saturday. Mannix came to the rescue in short order, fixed it, and at a reasonable price.

Silvio G was the technician, and he was GREAT.

We would definitely use Mannix again!

I have been using Mannix for about 5 years. They have been really great to work with. I have used them instead of the original installer (no confidence) who the home builder subcontracted too. Mannix prices prices and quality that I can feel good about. In addition, I have had a more challenging issue with Carrier Green speed unit that Carrier (the manufacturing) had a lot of trouble diagnosing. It required several visits from Mannix to work through Carrier's troubleshooting requirements to resolve. While some HVAC companies would see this as an opportunity to nickel and dime on service fees, this wasn't never the case Mannix. I have appreciated how Mannix has treated me as customer.

We switched to Mannix from another company about a year ago. They have been superb - timely, professional, responsive. The most recent work was a great example of that high standard. I’m glad we made the switch!

Excellent service and price from a local business that knows how to treat customers. No upsell talk or pressure - they know the price they give is fair. The installation team was very clean, polite and did the job well. Highly recommended!

I was very happy with the speedy and easy service from Mannix when replacing our furnace. Their sales person was not pushy at all and had a lot of excellent feedback so we got the best deal that works for us. I'm happy with the price and the quality of service thus far. I recommend looking at them for your HVAC needs.

My experience with Silvio was top notch! I work as a property manager and use Mannix often for our rental properties. Silvio was fast, professional, and extremely accommodating! Got the job done and went above and beyond with his cleaning and work.
