DVS Home Ventilation Reviews 165

We were really pleased with Digger who came to see us and talked us through about the DVS. It has been worth every penny we don't have any more condensation on the windows even though we are double glazed we still had a little, but now everything is bone dry. We get the filter changed every July and are very pleased with it. We would just like to say thank you very much best thing we ever had done.

Brent who came a explained about the DVS product was easy to talk with and clear in his presentation. I felt no pressure but very much included in what was being offered and the options available. A very good experience.
The installer was friendly, efficient and did a great job as I am very much enjoying the positive effect of the DVS unit on the home and the difference it has made. Thanks team

very good service all-round.Supply issues encountered which delayed the installation of 4 units indoors and 1 outdoor unit. we were kept informed and advised of the delays.when the due date arrived the team promptly assembled at our place to install all units as arranged. They worked meticulously all day long from 7.30 in the morning until 10pm that night to complete the full installation.above and beyond what was expected.many thanks to Russell for his diligence and hard work ethic.

Cleaned up spotlessly and all rubbish removed.

It was an easy sale for us, as the system was very well demonstrated, and met all of our requirements.
The installation went very smoothly. The installer was very polite and answered all the questions that we had.

Highly recommended

We recently had a DVS system installed in our home, within 24hrs the system showed amazing results no more crying windows etc. The installer was extremely good at what he did and explained every thing to us, this was possibly the best installation of any
thing we have had in our home, Many Thanks

The install of our DVS was completed efficiently and to a high standard. The installer was pleasant & polite and cleaned up as he went. Thanks!

Pleasant polite crew. Installed without fuss. Tidied up at they went. Not sue the bathroom vents extract steam as well prior to venting outside though.

Updated review. DVS were very helpful and contacted me the day after this review. They have since put in an external air supply unit so the air comes from outside instead. Much better for our situation, working well. Thanks Team.

Not enjoying our dvs, air smells musty from the attic. We had to turn if off as my husband's breathing was effected and he had to go to the doctor for asthma and allergy medication. It stopped when we turned off the dvs started again months later when back on. Feel like we have wasted thousands. We have adjusted the settings as per phone advice. Will now email for further resolution.

The woman who came around to assess for a quote was excellent and this sold it for me. The installer was fast efficient clean highly skilled and very helpful and polite. Couldn’t have asked for more.

So the initial consultation was good, but we already had to sent reminders for appointments, foreshadowing what was to come. We opted for some optional features including the summer bypass, ending up with one of their most expensive packages. The idea here is to blow in cold air from the cold side of the house into the house, bypassing the heat exchange, in order to help it cooling down faster in summer in the evenings. The installation crew seemed to be inexperienced, one thing that worried me a bit was the advice to duck-tape the unit after replacing the filter. Because it was warm we started using the unit with summer bypass on -- this had two issues: (1) the fan was so noisy that we had to turn it down at night, (2) it made the house warmer, not cooler. It took me some time to establish that the unit was not correctly installed, I took photos taken of the controller to illustrate this (links are not allowed here but you can find a link in my review on google) -- it shows how the temperature drops once the summer bypass is turned off. So I contacted them again and after initial contact this basically got lost in their system. This was 4 weeks ago, no response yet.

Update: since posting this we had better communication and a service by a knowledgeable technician. This has improved the situation a bit. I still think the summer vent is not a particularly useful and overpriced feature, we did expect that this would really cool down the house (as the inlet is on the side of the house that does not get the sun where the temperature is much lower than in the house and under the roof) but the net benefit is that it merely does not heat it up by fresh air going through the heat exchange.

I will see how this performs in winter and update the review.

Very fast and good quality installation. Very informative and kind. A++

The summer option is a waste of money in Hawkes Bay, with a poor design, design underperforming. The smart sensor is not smart, we need to take over the control to get limited uses out of the system, and my partner is not happy. When coming to instore no real plan nor science in the system using tech. Has turned out to be a poor design Overall poorly engineered if it has been engineered. The system may be designed to hide what people think is working in fact good healthy humidity is not going on. No good use of materials that cardboard and $30 fan with $4 sensor and little piping plus $20 filter with $5 outlet vents would work manly times better is my current view. Unless they get it working we the buyer will need to repair it ourselves the new system else get them removed the system. Just built our own using science. I am very sad we aren't able to buy with a state of mind to turn it on and walk away and it would work. As a buyer discover it was not working to the best is not good. The problem must fall back on DVS training and level of science and not using tech? We wait and see what they come up with to make the system work with the basic parts used in an efficient way. For now big failure for us.

Such prompt and friendly service even in the full Level 3 Auckland lockdown. Very happy with the new DVS unit and it was a very quick install! Thank you!

Kevin was fantastic through the process, during trying covid lockdown conditions in Auckland on a constrained time frame and budget. We had limited floor-ceiling space in our 2-storey house to go downstairs to our rental unit downstairs. Kevin worked with the installation team to revisit and refit a solution that delivered us an affordable and effective win for both the upstairs and downstairs property. It really makes a difference to work with someone who is responsive on email and phone, and cares about the final outcome.

Atu and Willy did a great job, maintaining their professionalism and working as a team !

The DVS system was difficult to install in the small cupboard space , but they managed it skill fully.

DVS system is great and keeps the home fresh and have now installed it in both of our properties.

Absolute Winner - 12 months on now and by far the best thing we have done to eliminate crying windows in the mornings. All houses should have these installed - including all rental properties. So much drier and warmer.

Had our DVS and Heat pump put intogether , really impressed with the electrician they used. He was very efficient and clean and tidy.
And no more condensation from day one.
Coming from a place we owned for 36 years which had a HRV system in and never any condensation to a new house that had crying windows didn’t make a happy camper. We choose DVS because our consultant Pippa explained the system so that we could easily understand. And understand the difference in the two systems.
We are very very happy to have chosen both the heat pump and the DVS. Our thanks goes to Ryan Eccles for a superb neat install.

Can honestly not rave about DVS enough. We had it installed in our last home and loved it - saw results immediately and our home always felt warmer and much drier. After moving into our new home a year ago, we struggled constantly with wet windows and mouldy curtains. As the house was much bigger and more open plan, we were worried that installing a DVS this time around might not be as affective .... we were wrong! Dealt with both David (from Wellington) and Phil (from Auckland) who offered suprerb advise and customer service, they provided great options ... and here we are, now living in a much drier and healthier home. We saw instant results and have not had a single wet window since the system was installed. Truly believe this is the best money you can spend on your home!

After moving into my new home I quickly discovered how damp it was. I looked into ventilation systems and contacted Pippa, the local Thames DVS rep, on the recommendation of a friend. I am so glad I did. Pippa came out and assessed the house and then gave me her recommendations of which system would be the best. Pippa is very knowledgeable but at no time did I feel pressured, she is a pleasure to deal with. The whole process was very easy. Adams Electrical installed the system. Very pleasant young men who left the house as it was with the exception of the addition of a fabulous new system. In just a day I have noticed a difference in the heat retention of the house. We have not had a frosty night yet but the house feels drier. Very happy with the service and products I have received from DVS.

David was epic to work with, honest and really cared for doing the right thing. Brett the installer was very good. DVS is working perfectly, warmer house and dry windows!
