Build Tight. Ventilate Right.
Residential Heat Recovery Ventilation Installation
Modern homes are built more airtight than ever. While this improves energy efficiency, it also means homes need controlled mechanical ventilation to maintain healthy indoor air quality, remove excess moisture, and provide consistent fresh air.
Zenith Ventilation designs and installs residential heat recovery ventilation systems for new homes, passive houses, custom builds, project homes, multi-residential developments, and existing home retrofits.

Understanding the Problem
Why Airtight Homes Need Mechanical Ventilation
Modern energy-efficient homes are designed to reduce heat loss, but when a home becomes highly airtight, stale air and moisture can become trapped indoors.
Without proper ventilation, airtight homes may experience condensation, elevated humidity, mould growth, stale air, and a build-up of indoor pollutants or VOCs. Opening windows can help temporarily, but it does not provide consistent, controlled, or energy-efficient ventilation.
A residential HRV system continuously removes stale indoor air while supplying fresh filtered air throughout the home. At the same time, it recovers heat from the outgoing air to reduce energy loss and improve comfort.
Signs Your Home Needs Better Ventilation
- Condensation on windows or glass doors
- Persistent stale or stuffy indoor air
- Mould growth or musty smells
- High indoor humidity
- Poor air movement in airtight spaces
- Indoor pollutants or VOCs lingering inside
- Discomfort in bedrooms or living areas
- Ventilation issues after renovation or air sealing
The issue is often not the home being “too efficient.” It is that the home needs a ventilation system designed to match its airtightness, layout, occupancy, and performance requirements.
How We Solve It
The Zenith Approach to
Healthy Home Ventilation
We design and install heat recovery ventilation systems that provide consistent fresh air without compromising the energy performance of the home.
Our process considers airflow requirements, duct layout, acoustic performance, system balancing, commissioning, and how the ventilation system integrates into the overall building design.
-
Continuous Fresh Air Exchange
HRV systems remove stale indoor air and supply fresh filtered air throughout the home.
-
Heat Recovery Efficiency
Heat energy from outgoing air is recovered to help reduce unnecessary heating and cooling losses.
-
Balanced Airflow Design
Supply and exhaust airflow are carefully designed and balanced for consistent whole-home ventilation.
-
Installed & Commissioned Properly
Our team handles installation, air balancing, commissioning, final handover, and client support.
Built for Modern Homes, Installed by Specialists
Residential ventilation is not an add-on service for us. It is what we do every day.
With over 17 years of experience installing heat recovery ventilation systems, Zenith Ventilation understands the importance of proper airflow design, installation quality, acoustic performance, energy efficiency, and system commissioning.
We regularly work on:
- Certified Passive House projects
- High-performance homes
- Custom architectural homes
- Project homes
- Multi-residential developments
- Existing home retrofit
Designed Early. Installed Properly.
The best ventilation outcomes happen when HRV design is considered early in the building process. Zenith Ventilation regularly works with builders, architects, building designers, mechanical consultants, passive house certifiers, and energy assessors to integrate ventilation systems properly into the home. This helps support smoother installation, better building performance, and long-term system reliability.

Common Questions
What Homeowners Ask Us
-
Portable dehumidifiers are effective in a single room, but they don't address the cause of moisture build-up (lack of fresh air exchange), and they need to be emptied manually. A ducted system distributes through every room and runs automatically — it's not a comparison of equal solutions.
-
Yes. HRV systems are routinely retrofitted into existing homes. We design duct runs to work with your ceiling and roof space, keeping building work to a minimum.
-
Most homeowners notice fresher air and less condensation within the first few days. Humidity and air-quality improvements continue to stabilise over the following weeks.
-
Very little. The fans are low-wattage, and because the heat exchanger recovers warmth from outgoing air, an HRV system typically reduces heating and cooling costs overall.
