Lossnay Systems: Fresh Air and Energy Efficiency for Your Auckland Home

If you’ve ever walked into your home and thought, “Hmm, it feels a bit stuffy in here,” you’re not alone. Modern homes in Auckland are built to be warm and airtight, which is great for keeping energy bills down, but not so great for air quality. That’s where a Lossnay heat recovery ventilation system can make a big difference.

At Heat & Cool, one of Auckland’s leading specialists in Lossnay and integrated heat pump solutions, we’re seeing more and more Auckland homeowners, families, and property investors asking about Lossnay systems. They want homes that feel fresher, stay drier, and run more efficiently year-round.

So, let’s chat about what these systems are, how they work, and why they’re such a smart addition to your home.

What Is a Lossnay System?

Think of a Lossnay system as your home’s lungs - it breathes in fresh air and breathes out stale air, but it does it smartly. Developed by Mitsubishi Electric, Lossnay is an energy recovery ventilation system that keeps your indoor air clean without wasting the warm (or cool) air you’ve already paid to heat or cool.

Here’s how it works:

Lossnay extracts stale, humid air from rooms like your kitchen, bathroom, and bedrooms. At the same time, it draws in fresh, filtered outdoor air. The clever part is its heat exchanger, which recovers up to 80–90% of the heat (or cool air) from the outgoing air and uses it to pre-warm or pre-cool the incoming air. So, you get a constant flow of fresh air, without the chill of leaving a window open in winter.

Unlike a basic extractor fan, Lossnay is a balanced ventilation system. That means it pulls out and brings in air at the same rate, keeping your home’s air pressure stable and comfortable. This is especially important in airtight New Zealand homes where moisture, CO₂, and allergens can build up if there’s no effective ventilation.

How Lossnay Systems Improve Air Quality and Efficiency

1. Say Goodbye to Allergens, Damp, and Mould

New Zealand sits among the highest nations globally for asthma and allergy rates, and most Auckland homes will face spikes in humidity and airborne irritants throughout the year, especially in spring and the damp months.

Poor ventilation contributes to what’s called “Sick Building Syndrome”, where air pollutants, moisture, and carbon dioxide levels adversely affect health. Lossnay systems tackle these concerns with high-performance filtration that catches pollen, dust, and urban pollutants, making them ideal for families and households with respiratory sensitivities.

Lossnay systems help by:

• Constantly filtering incoming air to catch pollen, dust, and pollutants

• Extracting humid air to prevent condensation and mould growth

• Maintaining a healthy, comfortable humidity balance throughout your home

Studies show that mechanical ventilation systems like Lossnay can reduce indoor-generated particles by up to 90% compared to homes that rely on opening windows. That’s a big win for anyone with respiratory sensitivities.

2. Enjoy Year-Round Energy Savings

We all know how quickly energy costs can climb, especially when you’re heating or cooling your home. With Lossnay, you’re not losing all that treated air every time you ventilate. Instead, the system recovers energy from outgoing air to pre-condition the incoming air.

That means:

• Up to 30% lower heating and cooling bills

• Less strain on your heat pump or air conditioning system

• Better comfort in every season

For families watching their power usage or landlords meeting Healthy Homes standards, this system ticks all the boxes - healthy air, lower costs, and better compliance.

3. Consistent, Filtered Airflow for a Healthier Home

One of the best things about Lossnay is how even your home feels once it’s installed. There’s no more “stuffy room at the back” or cold pockets. Instead, you get steady, filtered airflow throughout every space. It’s not drafty, it’s just right.

Integrating Lossnay with Heat Pumps

If you already have (or are planning to install) a Mitsubishi Electric heat pump, Lossnay is the perfect partner. The two systems can be integrated to share ducting and controls, so you can manage temperature and air quality together.

Seamless Smart Control

With Mitsubishi’s smart Wi-Fi options, you can customise:

• Airflow levels

• Operating schedules

• Temperature settings

• Humidity preferences

Whether you’re at home or on the go, you can adjust everything right from your phone. It’s ideal for busy families or anyone who wants a “set and forget” system that just works.

Energy Recovery in Action

By pre-tempering the air that enters your home, Lossnay takes a load off your heat pump, especially on those chilly Auckland mornings. Research from BRANZ found that energy recovery systems like Lossnay can run at 55–90% efficiency, depending on installation quality. That translates to smoother performance, lower costs, and a longer lifespan for your heating system.

Example Case Studies

Family Home in Albany

This family was dealing with morning condensation and seasonal allergy flare-ups. After installing a Lossnay system with their Mitsubishi Electric ducted heat pump, they noticed immediate improvements - no more condensation, noticeably fresher air, and a 22% drop in heating bills within six months. Even better, their kids were sleeping more comfortably at night.

Rental Properties in Auckland

A property investor added Lossnay systems across several rental units to meet Healthy Homes requirements. The result? Happier tenants, fewer maintenance calls about dampness and mould, and lower overall running costs.

Inner-City Apartment

An Auckland landlord fitted Lossnay with Wi-Fi control in a central apartment. The system could be managed remotely, and tenants reported cleaner air and lower power bills, leading to faster lease renewals and higher satisfaction.

Frequently Asked Questions

What makes Lossnay different from other ventilation systems?

Unlike standard extractors, Lossnay recovers energy from the air leaving your home, keeping you comfortable while reducing waste.

Can it really help with allergies?

Absolutely. Lossnay’s continuous filtration removes dust, pollen, and pollutants, ideal for anyone with allergies, asthma, or respiratory sensitivities.

Does it meet Healthy Homes ventilation standards?

Yes, and then some. Heat recovery systems like Lossnay exceed Healthy Homes requirements, helping landlords provide healthy, compliant living spaces.

Will it increase my power bills?

Quite the opposite! Because it reuses energy from your indoor air, Lossnay can cut your heating and cooling costs by 15–30% a year.

Can it be added to my current setup?

In most cases, yes. Lossnay can be retrofitted into many existing ducted or wall-mounted systems. Our team can assess your home and recommend the best option.
