★★★★★ 5.0 Bob C · Feb 2026

Recently needed to have a new HVAC system installed. I got multiple quotes from companies and decided to go with Mann-In based on neighbors reviews and my research. The salesman Aaron was top notch. Very response to any questions I had and the quote was very detailed. He was the only one that stated I need to have a new liquid line installed because my current one was too small. I’m coming off R-22 system. From what I gather yes the one I had would have technically worked but it was recommended to upgrade. The install crew that came was exceptional. They were on time and each was very knowledgeable and polite. They took the time to do a nice install and it shows. So glad I chose this company for my install. Highly recommend Mann-In for HVAC.

Husband and I have called multiple times the past 2 months to have someone come look at our heater. Was told someone would be out at our house that next week (the first time we called), no one ever showed up. We’ve called back multiple times and have received a “oh yeah no one ever followed up with you, we’ll have someone get back to you”, weeks have gone by and still no one has called us or gotten back to us. Horrible service.

We recently had two air conditioners, and one furnace installed by Mann-In. Dan, Trevor, Aaron and the whole team were great to work with. Communication and follow up were excellent from start to finish. They did an excellent job with the installation and at a very competitive price. The team is totally committed to customer satisfaction, and I can't recommend them enough. Thank you Mann-in!!

Experiencing a failure of the air conditioning unit in the middle of a heat wave with indoor upstairs temperatures reaching 85 degrees F is no fun. Luckily, Mann-In came to the rescue and demonstrated why we have relied on their services for many years. Their technician (Colt) was dispatched promptly and diagnosed the problem quickly (blown fan motor). Throughout the time addressing the issue, the scheduling people (Debbie and Jody) were extremely responsive, helpful, understanding and courteous and our emergency outage was resolved 2 days later, at a very reasonable cost. All staff deserve a 5 star rating.

★★★★★ 5.0 A. Feinstein · Jul 2025

Very pleased with Mann-In as they did the work quickly and at a fair price. I initially contacted Mannix but they provided a ripoff quote that was 3X what it should have been.. I assume trying to take advantage of customer during the heatwave. Will never call anyone other than Mann-In going forward.
