Commercial HVAC Installations

Home Commercial HVAC Installations

We specialize in the installation of Mitsubishi Electric/VRF, and Rheem unitary equipment.

Our Commercial Teams are hard-working, efficient, and well-equipped to handle commercial and multi-residential projects up to $4M. We have installed HVAC in many of the Seacoast’s landmark buildings, working closely with top GCs and Developers, to provide competitive and robust comfort solutions to all building types and uses.

We are a Mitsubishi certified Diamond Commercial Contractor – proud to be 1 of 5 DCCs in all of NH! Diamond Commercial Contractors possess deep product knowledge, expertise, and experience with Mitsubishi Electric VRF systems, as demonstrated by a series of eligibility requirements and qualifications. As a result, Diamond Commercial Contractors are particularly well-suited to represent CITY MULTI® products in design-build, retrofit, and build-to-suit project applications.

Our technicians are trained and experienced in all walks of light-commercial HVAC work, and consistently go above industry standards for quality and code regulations. Leave the design process to us; we partner with local Engineers to provide affordable stamped mechanical sets for building owners and developers. Once a mechanical design has been established, there is no better team of installers in the NH Seacoast and Southern ME area. From mill renovations, to strip mall complexes, our business revolves around your comfort. Please contact us for bidding opportunities on equipment change-outs, or new construction.
