Mann-In did an AMAZING job of meeting our expectations in every way. HVAC replacement is expensive and we knew when it came time, we wanted to reconfigure things and almost start from scratch given how haphazard our old set up was. They designed a well thought out system to maximize efficiency while at the same time minimizing ducts and pipes that previously ran intrusively all over the space. The install went great. They worked hard all day and left the space better than when they found it. (When Mann-In installed HVAC for my parents, this was also the case.) The only thing we would change at all is the choice to go with the premium variable speed system as it requires use of the proprietary Carrier wifi thermostat and Myinfinity app which is pretty bad. Almost makes me want to replace it with an ecobee which would basically cancel out the variable speed ability. It's that bad. In any case, we love the installer, Mann-In

I found this company through Checkbook. They are A+, first-rate, top-notch. I found their advice on which type of Carrier units to purchase was honest, direct, and spot-on. They did a complicated installation of two complete HVAC units (upper and lower floors of house) in a crowded mechanical room. Couldn't be happier with Mann-In.
