The most common phone call we get about energy recovery ventilation does not start with a technical question. It starts with a location. “We’re building outside Frederick, Maryland, and we cannot find a certified Zehnder installer anywhere.” Or Durham, North Carolina. Or Winchester, or Richmond, or a county in West Virginia we had to look up.

The equipment is not the hard part. Anyone can order an ERV. The certified installer is the scarce resource, and if you are building a tight, high-performance house, installation quality decides whether the system delivers its rated performance or just hums in the basement. So this post answers the location question properly: where we work, how far we go, and how an out-of-area project actually runs.

The Core: 60 Miles Around Goode, Virginia

HOLISTIQ is based in Goode, in Bedford County between Lynchburg and Bedford. Most of our ERV work happens within about 60 miles of the shop, which covers the places you would expect:

• Lynchburg and its renovation-heavy older neighborhoods, where tightened-up houses need the ventilation they lost
• Bedford and Smith Mountain Lake, where humidity works on closed-up lake houses year round
• Forest, where new construction is code-tight from day one
• Roanoke, where the valley holds pollen and haze and houses sample it constantly
• Charlottesville, where the high-performance building crowd specifies Zehnder by name

Inside this range a project looks like any local trade call: walkthrough or plan review, written quote, install, commissioning. Each of those cities has its own page on the site if you want the local detail, starting from our energy recovery ventilation overview.

The Travel Range: Multiple States, One Standard

Beyond the core, we take scheduled ERV projects across state lines. The current footprint covers Virginia end to end, North Carolina, and Maryland. That is not a marketing flourish. It reflects the actual geography of Zehnder certification: the factory-trained installer list is short, and enormous stretches of the mid-Atlantic have nobody on it.

North Carolina projects tend to come from the Triangle and the Triad, where energy-conscious builders are putting up tight custom homes. Maryland projects cluster around Frederick, the DC-adjacent counties, and Baltimore’s suburbs, plus the occasional Western Maryland build along I-68. We wrote up the Maryland side in detail on the Maryland ERV installation page.

How a Travel Project Works

Distance changes the logistics, not the standard. A travel installation runs in four moves:

1. Remote design. You send plans for new construction, or photos and measurements for a retrofit. Josh designs the system on paper: unit sizing, register placement, tubing routes. You get a written quote against a specific Zehnder system before anyone drives anywhere.
2. Equipment ships to the site. No waiting on a van full of parts making a 300-mile round trip twice.
3. One mobilization. Installation lands as a block of consecutive days, usually two to four. On new builds we coordinate the window with your general contractor so rough-in lands in the correct phase.
4. Commissioning before we leave. Airflow measured and balanced at every register, all modes verified, written report in your hand. The report is the proof your system performs to spec, and on high-performance builds it is what your energy rater wants to see.

Afterward, maintenance is genuinely light. Filter swaps are a five-minute homeowner task. For anything beyond that, you call the person who designed and installed the system, which beats calling a dispatcher in any state.

Why We Would Rather Drive Than Watch a Bad Install

Josh got his Zehnder certification because he kept seeing what happens without it. An ERV that skips proper design and commissioning still ventilates, roughly, but the balance is off, rooms get missed, and the energy recovery that justified the price never materializes. The homeowner cannot see any of that. It just performs worse forever.

A certified installer who travels fixes the actual problem, which is that this equipment deserves better than the nearest available generalist. If your project is somewhere between Raleigh and Baltimore and the ventilation line item is stuck, the distance from Goode is our problem to solve, not yours.

Common Questions

Do travel projects cost more than local ones?

The system itself prices the same way everywhere: size, register count, new build versus retrofit. Travel adds a scheduling block that we plan around, which is why out-of-state projects work best booked ahead. Everything lands in one written quote before you commit.

Which states are actually in range?

Virginia is home turf. North Carolina and Maryland are regular travel range. For anything else nearby, call and ask. The schedule decides more than the mileage does.

Can you work with our builder or architect remotely?

Yes, and it is the normal case on new construction. Design happens from drawings, coordination happens with your GC’s schedule, and our site time lands in the correct construction phase. Architects get their ventilation design intent pressure-tested before rough-in instead of after.

What if we just need to know whether our house is a candidate?

Send photos and a rough floor plan through the contact page. Retrofit feasibility usually comes down to routing paths, and Josh can read that from good photos of your basement, attic, and mechanical space.
