Customer testimonials
More than 500,000 New Zealanders live in a home with at least one HRV product. Here’s what some of them have to say about HRV home ventilation.
Matt Cameron “Now we know we can get a full night’s sleep, the kids can sleep well” 
Pamela Kaval “My son used to have really bad asthma, now he doesn’t, since we got the unit” 
Sarnim Dean “…dust is minimised, condensation decreased and general wellbeing maximised. Thank you HRV!” 
HRV versus heat pumps
Why not both! HRV home ventilation, whether you choose a positive pressure or balanced pressure system, replaces the damp, stale air in your home with fresh, drier, filtered air. While some systems and some optional accessories help you manage the temperature in your home, HRV home ventilation isn’t a heating system.
That’s where heat pumps come in. HRV home ventilation works well alongside heat pumps, and we often install both at the same time. And because drier air is quicker and easier to heat, your heat pumps will operate even more efficiently.
