Capabilities

One contractor. Design through commissioning.

Fewer hand-offs means fewer RFIs, fewer schedule slips and one name on the warranty. Here is what our own crews and our own shop stand behind.

01

Design-Build & Engineering Support

We work with your MEP engineer from early budget numbers through submittals. Constructability input, equipment selection support and coordinated shop drawings keep problems on paper instead of on the roof.

▸  Early budget and value-engineering input
▸  Equipment submittals and shop drawings
▸  Trade coordination before fabrication

02

Commercial HVAC Install & Retrofit

Rooftop units, split systems and VRF for offices, retail, industrial and multi-tenant buildings. New construction or occupied retrofits, scheduled around your tenants.

▸  Rooftop packaged units and split systems
▸  VRF and heat recovery systems
▸  Replacement and phased retrofit work

03

Boilers & Hydronic Piping

Denny's carries the 2B state boiler certification, which allows installation of low-pressure boilers of unlimited BTU capacity. We pipe the whole system, from the boiler room to the terminal units.

▸  2B state-certified boiler installation
▸  Hydronic piping, pumps and accessories
▸  Replacement and new-build plants

04

Building Automation & Controls

Controls integration, scheduling and monitoring so the building performs the way the design intended after the engineers have left the site.

▸  Controls integration and start-up
▸  Scheduling and setpoint management
▸  Support through commissioning

05

Sheet Metal Fabrication

Our own sheet metal shop builds custom ductwork and fittings. That puts lead time and quality in our hands, not a supplier's.

▸  Custom duct and fittings
▸  Shop-built to the coordinated drawings
▸  Fast turnaround for field changes

▸  Kitchen and restaurant ventilation
▸  Planned maintenance and service agreements

How a job runs

From drawings to commissioning.

02

Submittals

Equipment data and shop drawings, coordinated with the other trades before anything ships.

03

Fabricate

Ductwork and fittings built in our own sheet metal shop, on your schedule.

04

Install

Experienced field crews led by installers who know how a whole job goes together.

05

Start-up & Service

Start-up, commissioning, then maintenance and service for the life of the system.
