Don't just take our word for it ...

Here's what some of our customers have to say about DVS®

We had our Fujitsu heat pump installed today. Just wanted to thank you and your team - the guys did a great job and the unit is wonderful! We appreciate the great service you gave us and can now enjoy the winter!  Thanks again.

My wife and I are thrilled with the insulation and DVS with the Auto Summer Vent system you installed in summer. Our house now feels drier and most importantly, our two pre-schoolers that suffer from allergies are breathing easier. We are thrilled that having the DVS work 24 hours a day right throughout summer - with the outdoor air supply when our roof is too hot - was well worth the investment. The consultant, installers and company have been great to deal with and we are now looking at winter heating options to make our house and family more comfortable.

My wife and I are a great supporters of DVS, we have the system in our own home as well the rental properties we own , they keep the houses nice and healthy for us as well as our tenants, and free of mould. This can be a problem here in the Waikato. They are well worth the investment.

Just wanted to thank you guys again for the insulation. The guys came and installed it today and were amazing! They were really friendly and informative about what was happening and they did a really tidy job! Overall we were really impressed with the whole company.  Thanks so much - we're loving having a fully insulated home and looking forward to the big changes we'll notice next winter.

I just wanted to let you know how happy I am with the DVS, no more condensation on the windows, the house is no longer damp, and the air smells purer. I know it is not a heating system but since the dampness has been removed the house feels much warmer. I would certainly recommend that a DVS be installed in all homes as it makes a much healthier living environment.

I recently purchased a DVS home ventilation system as well as a Fujitsu Heat Pump through DVS. My house was built in the 1920's and had no insulation or any form of heating, so as you can imagine - it was VERY cold, and the windows dripped with condensation! I wish I had made the investment sooner, as I absolutely love coming home to a nice warm home! Its so good to be able to set the timer so you can wake up to a nice warm house also.

"DVS staff have done a very professional job in my home - from sales to installation the process was extremely smooth and comfortable. I would highly recommend them!"

"I recently had a DVS system installed as our home is over 40 years old and in the absence of any reasonable insulation was damp and inclined to attract mould and as all of us are prone to extreme allergies, I was concerned about the poor air quality in addition to the dampness and evident mould spores. Right from the first phone call I cannot fault a single thing; a professional and friendly consultant turned up advising on the best air filters to suit our needs and a later the tradesman not only turned up when he said he would but he cleaned up after himself and removed the mouse found decaying in my wiring! But service aside I am so incredibly grateful that after only four weeks we are all sleeping and breathing better; Spring comes with mixed feelings for our family as the weather warms the pollens increase but fingers crossed so far I haven’t heard a single sneeze from anyone which for this time of year in unbelievable! "

"Our DVS system has been installed recently and since then results have been absolutely incredible! Our windows which have always been extremely wet now are completely dry. We are still marvel at the difference every morning when we open the curtains. We will certainly be recommending your product to others, and wonder why it took us so long to get the system. We are looking forward to a drier and healthier home."

"We used to have water pouring down our windows everyday. Since installing the DVS in our home we haven't had a single drop, not even when we cook or have showers."

"The DVS consultant left not one thing unturned. She has a great sense of humour and was not at all pushy with the sale. It was refreshing to have someone as good as Helen giving me a quote. I am always praising the DVS system and benefits to friends."

"We have a holiday house in Turangi which is often left closed up for weeks at a time in between guests. The house had a faint mouldy smell (we thought from just being closed up) and we kept wondering why our son got a bad cough every time we stayed at the house. Since we had our DVS installed it has been fantastic. The house feels warmer when we arrive (as now it is really dry). And our son never gets sick while we are there -- which is obviously better for him and everyone else on holiday. Thanks DVS - we love our ventilation system!!"
