We’re in on the ground floor
When you’re building a new home, the systems you can’t see matter just as much as everything you can. The comfort, reliability, and efficiency of your HVAC, plumbing, and electrical work are determined long before the walls go up — and getting them right from the start saves headaches, callbacks, and costly fixes down the road.
A+ Derr has been a trusted trade partner for residential new construction across the Tri-State area for over 50 years. Whether you’re a builder looking for a reliable mechanical contractor or a future homeowner who wants to know your new build is in good hands, we bring the experience, the manpower, and the attention to detail your project deserves.

Comprehensive HVAC, Plumbing, and Electrical Rough-Ins
Three trades. One trusted partner.
Having a single contractor handle your HVAC, plumbing, and electrical rough-in simplifies your build. Less coordination, fewer scheduling conflicts, and one point of contact who knows your project from the ground up.
- HVAC
We design and install heating and cooling systems built for the home’s specific layout and load requirements — not a one-size-fits-all approach. From ductwork rough-in to final system startup, we make sure every room gets the comfort it needs. - Plumbing
From rough-in through trim-out, our licensed plumbers handle water supply, drain, waste, and vent systems with the precision new construction demands. We work on schedule and on spec — every time. - Electrical
Our electrical team handles rough-in wiring, panel installation, and final connections with the care and code compliance your project requires. We coordinate closely with your GC to keep the build moving.
Â
Serving Builders and Homeowners Across the Tri-State Area
A+ Derr’s residential new construction services are available across Evansville, Newburgh, Henderson, Owensboro, Boonville, Fort Branch, Mount Vernon, and more. Our new construction team is built to move with your project — staying on schedule and on site throughout every phase of your build.
We’ve had the opportunity to work on new construction projects in some of the area’s most sought-after neighborhoods and developments, including:
- River Ridge
- Copper Creek
- Pleasant Valley
- Victoria Woods
- Creekside Meadows
- Green River Meadows
These are neighborhoods we’ve worked in firsthand — not just markets we cover on paper. If you’re building outside of an established development, we work on custom builds and independent lots throughout the region as well. Wherever your project is, we’ll be there.
Why Choose A+ Derr for Your New Construction Project?
Built on trust. Built to last
New construction projects live and die on reliability. A trade partner who misses a rough-in inspection or falls behind on scheduling doesn’t just slow down your timeline — they cost you money. A+ Derr has spent over 50 years building a reputation as the partner builders and homeowners can count on.
- Licensed across all three trades — one contractor, no gaps in coverage
- On-schedule, on-spec work — we understand how a build timeline works and we protect it
- Code-compliant in every market we serve — Indiana and Kentucky licensed
- 50+ years of Tri-State experience — we know these markets, these inspectors, and these builds
