Delivering Fresh and Clean Air for Every Home

In today's airtight homes, maintaining good indoor air quality is more crucial than ever. Poor ventilation can lead to stale air, excessive moisture, and even mould, which can negatively impact indoor air quality and your health.


Our MVHR systems provide a balanced solution, continuously exchanging stale indoor air with fresh outdoor air while maintaining your home’s temperature and energy efficiency.  


The result? A healthier, more comfortable living environment with improved air quality, reduced allergens, and better humidity control.


By choosing an MVHR, you're not only meeting building regulations and creating a more energy-efficient home, but also ensuring that your family enjoys fresh air and comfortable indoor environment all year round.

What Our Customers Say About Us



I had a great experience with Flynn Heat Recovery. I had contacted 1 - 2 other MVHR suppliers, but Maurice was the only person to take the time to explain the system & what it might mean to our project. The installation was carried out with minimum fuss & Dean & Pedro worked well with our builder to identify the best route for the piping. I am also happy with the post sale / installation service. I get a quick response to any question & I am glad we went with Flynn Heat Recovery. We are back in the house nearly 4 months now and are delighted with the air quality.

Excellent company to deal with. I needed two residential ventilation units assessed, one needed spare parts & the other a service. Invoices all provided online ahead of any jobs done, the guys arrived on time on the days of the works & were very pleasant & happy to explain what they were doing/fixing. I thought for a second that I had a follow up problem & they were very responsive in terms of coming back &reviewing, but as it turned out all was okay & it wasn’t required. Very happy to go back to them for ongoing maintenance of my houses systems in the future.

Excellent company to deal with: Shane, Dean and Pedro are very professional, arrive on time, do the job efficiently, and provide excellent advice also. Would recommend. Clean your HRV ducting, folks, it's worth it.
