HRV & ERV Ventilation Ducting
I install and correct the ducting for HRV and ERV systems: supply, exhaust, and fresh-air runs laid out for balanced whole-home ventilation in tight modern homes.
What I do
- Supply and exhaust duct runs for HRV/ERV units
- Fresh-air intake and stale-air exhaust terminations
- Duct routing and support for balanced flow
- Insulated ducting to prevent condensation
- Corrections to poorly laid-out existing systems
Common problems I fix
- Unbalanced systems that over- or under-ventilate rooms
- Uninsulated ducting that sweats or drips
- Intake and exhaust terminated too close together
- Crushed or unsupported flexible runs
Good-fit projects
- New and energy-efficient home construction
- Tightly sealed renovations needing fresh air
- Homes adding an HRV or ERV
- Existing systems that never balanced properly
HRV and ERV systems bring fresh air into tightly built homes while recovering energy from the air they exhaust. They only deliver on that promise if the ducting is balanced, sealed, and insulated. I install and correct the duct side of HRV and ERV systems so whole-home ventilation actually works.
HRV or ERV, and why the ducting matters
An HRV recovers heat; an ERV recovers heat and some moisture. Either way, the unit depends on balanced supply and exhaust ducting reaching the right rooms, with intake and exhaust terminations placed correctly outside. Poor duct layout is the most common reason these systems disappoint.
Why HRV ducting sweats or drips
Ducting carrying cold outdoor air needs insulation. Without it, warm indoor air condenses on the cold metal and drips. I insulate the intake and exhaust runs, support them properly so they do not sag, and seal the joints so the system ventilates without creating moisture.
Fresh air in tight modern homes
Energy-efficient homes in the corridor are sealed tightly enough that they need mechanical fresh air. Laying out the HRV/ERV ducting well, with balanced runs, short paths, and correct terminations, is what turns a sealed home into a comfortable, well-ventilated one.

Frequently Asked Questions
What is the difference between an HRV and an ERV?
Both recover energy from outgoing air to temper incoming fresh air. An HRV transfers heat only; an ERV transfers heat and some moisture, which can help manage humidity. Either way, the ducting has to be balanced and sealed to work, and that is the part I install and correct.
Why does my HRV duct sweat or drip?
Usually the ducting carrying cold outside air isn't insulated, so warm indoor air condenses on it. I insulate intake and exhaust runs and seal the joints so the system moves fresh air without creating moisture problems.
