DVS Home Ventilation Avis 

We are a return consumer, the first system was great this house was a one store 1950s, however the second house built mid 1980s with a 2nd store added on upstairs, has been awful. They said we should get the basic mode and the only difference was that it could no have add on's like heater transfer system ect which we were happy with that. But this basic mode has to thermostat on it so when the air temperature in the roof is very cold the fan continues to go and freezing cold air is blown into the bedrooms, this feels like a door is open, so cold, also the air smells dusty which is awful and unhealthy, we cant have our kids sleeping in these bedrooms with this happening. So we paid $2700 for some thing we have turned off. I will be ringing them again tomorrow im so unhappy I wish we had just got double glazing for this money instead

The DVS unit has made a huge improvement in the overall warm of the house.
Our home is only 7 years old and double glazed, but we had been getting bad condensation on the aluminium joinery. This was especially bad in the children's rooms.
Overnight this changed, we have found that even in the cold Christchurch winter we aren't needing to turn the heat pumps on as often.
I was initially concerned about running costs - the power bill has actually come down as we don't need to turn on heating as often.
I highly recommend this system!

My DVS is fantastic. No more condensation problems anymore. Money well spent. Service fantastic right from the start.

Fantastic Ventilation by DVS. Must for every Kiwi. Recommended with self experience.

Excellent customer service

Found that DVS responded quickly via the FB page messenger option and in person as well, great customer service! Highly recommend :-)

I just wanted to say thank you for your help Keith, you phoned within an hour of me calling the 0800 number, you came to our house on a Saturday to talk through each system and offer your expertise and knowledge, and within 2 weeks our DVS was installed.
Your installer (I didn't catch his name) from Magpie electrical did a great job, he arrived exactly when he said he would, talked me through the system and cleaned up after himself.
Thanks again

Very impressed with the service. The installer was experienced, completely competent and pleasant. A great service experience.

We received great service from DVS. I really appreciated that they were not pushy like other competitors and they gave me all the options to choose from. Since having the DVS installed we are overjoyed with the results. Dry windows from the very first day and ever since. My only regret was that we didn't install this sooner. I recommend them in every new home. We did not initially install one because we thought double glazing would prevent condensation, but it doesn't. A DVS is a smart and healthy choice for a well ventilated home.

We're delighted with our DVS reclaim. We previously had a competitor's version and it was noisy and ineffective - we were still wiping windows in the morning. We had to battle long and hard for a refund and removal. The DVS keeps the windows dry and it's silent. I think some of the competitors spend more on their marketing than their product development.
