Hi Christine, I just had to write and tell you about the amazing effects the Envirofan has had so far on my smelly carpets. I know you told me to run it continuously for 8 weeks and then contact you but I’m so excited after 9 days just have to thank you. The smell inside my house has almost vanished and the sub floor area doesn’t have the sour smell it did. I believe my carpets will recover and the fan isn’t even installed properly yet. The man I had doing the installation was to come back and mortar the bricks in and silicone around the unit and he got sick and hasn’t been able to do this yet so there are still air spaces around the fan and it’s working regardless! How good is that?! Many thanks for your fabulous product and your help and advice to me prior to me purchasing. Every brick house on piers should have at least one of these.

Christine thank you. And I have to praise the Envirofans. We’ve had them for 10 years and are still working great.

Hi Christine. We just wanted to thank-you for your great service. We received the package on Monday and the replacement parts have been re-installed and as it happens just in time for the expected downpour of rain that we desperately need. So all is good!

Hi Christine, The two Envirofans that purchased in July ’15 are working well after 6 weeks of continuous operation, another month on the timer. I can just hear them when the neighbours pool pump turns off. I would definitely recommend them. I am about to order another one.

I made telephone calls and emailed many companies in search of a suitable fix for my damp and mould problem in my home. The initial response right through to purchase, supply and installation instructions plus follow up received from Envirofan was nothing short of fantastic. Christine in the office was so helpful and knowledgeable, making me feel confident that their product would be a perfect choice. The product is high quality and was packaged well and received on time. It’s now installed, fully functional and has completely solved my mould and damp smell problem, even better than my expectations. There are a lot of products on the market but dealing with Envirofan who not only manufacture and distribute their product, they back it up with knowledge, assistance and after sales help. If I ever get asked for a recommendation for ventilation, ducting systems, Envirofan would be my first and only choice. Thank you Christine for making what I first thought would be an extremely difficult job, actually enjoyable and more importantly a total success.

After research, advice, trial and error I purchased the Envirofan Quad Fan Heritage Kit (EF10-4HK). Purchase, installation instructions, and after sale support was not only smooth, it was standout. The fan is effective, very quiet, and even attractive thanks to the attractive faceplate. The air that is extinguished is moist and stale (I know because I smelled it), which means the fan works a treat, which is surprisingly gratifying. Thank you Christine.

Thanks Envirofan, my order arrived perfectly on time. The quality of the sub-floor ventilation fans and solar panels purchased is very high and made from good quality materials. I have them now installed, running and can start to notice the difference of reduced humidity within my house. I also appreciate your after sales assistance.

Luke B.

I found the Envirofan website while searching for my sub-floor ventilation issue. The website contains some excellent information and dealing with Christine was fast and easy. She was able to provide me with all the information I required and I purchased two single brick units. Installation was easy and aided by the excellent DIY installation video. Installing Envirofan has made a significant improvement to my damp sub floor area and I am expecting the area to be completely dry once I have finished another project to divert ground water on the outside of my house. Thanks Christine and Envirofan!

Thank you so much for a great product that works!! I have had 3 single brick size fans installed using the solar panels for about 2 weeks and they work. Under our house was wet and cold, since installing the fans the area is drying out and the air is being circulated. This has meant that the bedroom above this void are now warmer and not damp! I am so very happy that my builder recommended them and ecstatic they work so well!

We bought a double brick house that had some moisture under the floor, with a nasty musty smell developing in the bedroom. We did have pre purchase building inspection, that advice proved to be very disappointing with respect to the subfloor moisture problems.

The sub-floor space was restricted, so we arranged for a builder to crawl under the house, taking a number of photos, numbered according to a floor plan of the house. Lots of water very damp soil, with moisture seen on the terra cotta pipes under the 3 bathrooms – looked like the pipes were broken or blocked and leaking. Very disappointed that this was not included in the pre purchase building report.

Obviously we had to find and fix the source of the water, then improve sub-floor ventilation.

Drain experts diagnosed broken sewer and stormwater pipes, with quotes of up to $50,000 to repair and reline pipes. Glad I did not trust their advice.

Lucas, of Wild Water Plumbing inspected the sewer pipes, and reported they were OK, but that the heat exchanger HWS has 2 drain pipes that were not connected to lines, so were discharging water beside the house. Thank you Lucas for your honest advice.

I hooked up 2 drain lines to the HWS and ran the ends into buckets in the back yard, and was staggered to see the total amount of water produced, seemingly much more water than the large house A/C produced. For some years water had been dripping from the HWS so the ground had become saturated – the cause of all the damp soil seen under the house in the photos.

So source of water identified and rectified – now to the sub-floor ventilation.

Subfloor ventilation firms quoted around $7,000 to remove the damp. But neither mentioned the complex but ineffective ducted fan system installed by the previous owner. So I lost faith in those 2 firms.

I Googled sub-floor ventilation and found Envirofan, and was impressed with their informative articles and videos.

I contacted Christine with a multitude of questions, all of which were answered comprehensively.

We chose the aluminium heritage vent, which looks even better installed.

Our final installation was for 10 fans – as a double brick house air flow under the house is very restricted, so we had to knock small passageways into each room’s subfloor perimeter to allow air to flow into that room and out via the fans. We used 3 large transformers and extra heavy duty garden 12 V garden light wire for the long runs under the house to the fans. Our final budget of time materials and fans was much less than the $7,000 quoted, with a far superior look and performance.

We used Holman Garden Lighting connection 3 way Tees so the actual connections to the fans and circuits were minimised – heat shrink wrap ensured water tight connections. Most connections were waterproof screwcap type on the Holman garden lighting system. The garden lighting wire and connectors are designed to be buried in the garden, so ideal for sub floor fans.

The final result performs magnificently, and the sub-floor is now dry. The system is on a time clock, so a few hours a day running time is more than adequate to keep the sub-floor very dry. The musty smell is now gone.

I don’t think I am an easy mark, but the first four firms – plumbing and ventilation – were really conning me with their advice and their quotes.

So finding Lukas of Wild Water Plumbing, and Christine at Envirofan, who are both fair dinkum and trustworthy folk, it was a great relief.

I have had to dismantle one of the Envirofans to adjust it to mate up with the existing system, and was impressed with the quality of the components, and elegance of design.

The cast aluminium vents are of exceptional quality, we had to trim one edge to fit under brick corbelling.

I believe that Christine and Envirofan are an excellent choice of these seeking a quality product, with quality support and advice, so a DIYer can achieve better than professional results, with a truly elegant enhancement to their house.

I enjoyed this project, and working with Christine as a team.

Was a pleasure to deal with Christine, explained everything well. Got quotes, payed the invoice and go. The Envirofans were shipped the next day. Have them installed and appear to be working well. All a very pleasant experience. Wish more companies trading online were as contactable by phone as well as emails. Thanks Christine for your help.

I just wanted to thank you for your tremendous help in sorting out our issue with our fan. Your attention to detail and customer service was simply first rate and given it was over the New Year holiday period even made it more special. The fact you bothered to suggest some DIY testing of the problem rather than simply sending out the product was refreshing from a customers point of view.

The customer service from Christine was excellent, responding to queries quickly and ensuring that the goods that I ordered arrived safely and on time.

Christine took the time to check that everything was in working order.

I would recommend Envirofan and I will certainly use them again.

Wanted to say that I am happy with my RF7 (Envirofan Roof Ventilation System) as an estimate I reckon it has decreased my cooling costs by 50%.

I can fully recommend the Envirofan QUAD Fan – Terracotta Vent replacements as a means of reducing moisture in a sub-floor area with inadequate ventilation. I installed these fans after a recommendation from a pre-sale Building & Pest inspection, with the dual aim of reducing high moisture readings in the sub-floor and also minimising risk of termite infestation, as the property is on acreage in the North Brisbane area. I only installed one of these quad fans initially on one end of the sub-floor and I could very quickly see the results of their operation. After another month, I installed the 2nd set of these fans on the opposite end of the sub-floor and the results are very pleasing. This would be the driest I have seen my sub-floor area in 17 years. Even after heavy rain in the last few months in the Brisbane area, the drying efficiency of these fans is excellent. The added benefit has been the removal of the damp musty smell in the subfloor area and this is also noticeable in the house itself, especially after it has been locked up for an extended period. I would also expect that risk of termite infestation has been reduced by removal of the damp conditions in the sub-floor area. The installation of the fans are very simple and the added bonus of the instructions being supplied by Envirofan, made the installation that much easier. All connectors required were provided and wiring from the Power adaptor was also marked to ensure correct DC voltage connections. These are definitely DIY installation. I used the calculations provided on the Envirofan website to determine the required number of fan units for the sub-floor area and this calculation appears to provide an accurate result (based on 4 air changes/hour) in that even though 1 quad fan set worked OK, the installation of the recommended 2nd set has resulted in excellent drying of the sub-floor area. An excellent product and the company representative (Christine) is very easy to deal with and the purchase completed by email and the EFT (electronic funds transfer) payment was an easy and pleasing experience. Thanks again.

Just a short note to say how pleased we were with the advice and service we received when purchasing our Envirofan quad-fan under floor ventilation system. The ease of payment and next day delivery were beyond our expectations. For service and advice we rate you 150 out of 100. Thank you again

Hi, I have used your Envirofan quad-fan a few years ago and they were excellent. My friend wants to install your fan. We are from Sydney. I am so glad to get in touch, as your sub-floor quad fan which we install, too compare to my neighbours with a $6000 alternate system, ours was far more effective and we have rave about your fan from day one to everyone who has sub-floor problems.

I have been putting it off to crawl under the house for some time. The moisture problem was so bad; I really did not want to find out for a while, especially with steel frame construction. I cut holes into the brick wall and installed 100mm PVC pipe air intakes to get the cross ventilation going. In the end the PVC pipes will be encased in concrete on the veranda side with a mesh grill to stop critters getting under the house. On the other side of the house I have installed the 6 Envirofan quad-fan systems. I checked under the house this morning after 2 months and the problem is completely solved! No moisture, no condensation. For now, all is well. Many thanks.

Hi Christine, the Envirofan arrived yesterday without delay via courier. Thank you very much for your assistance you have provided during the sale. You have been most helpful and it has been a pleasure doing business with you. If this new unit works for as long as the previous one then I will contacting you again in 2023.

Christine is an absolute pleasure to deal with. She is extremely customer service oriented and went above and beyond to help us resolve a small problem recently. We had 3 Envirofans installed more than 5 years ago as our property is on an overland flow path and our sub floor was constantly wet. The fans are extremely effective, long-lasting, quiet, they cost virtually nothing to run and the drying out of our sub floor has significantly removed that stinky muddy smell and in turn reduced our termite risk and allowed us to extend our termite inspections from 6 months to the standard annual inspection, which has also saved us money every year. We highly recommend Envirofan and have happily and confidently referred other people over the years and we will continue to do so.

Jodie S., Ashgrove, Qld

Great responsiveness in service and product effectiveness, Christine, only good things to say.

I recently purchased goods through Envirofan. I’m normally quite hesitant to purchase goods via email using EFT (electronic fund transfer), but with Christine’s help, I felt very at ease. My goods arrived promptly, and Christine was there every step of the way to answer my questions. I would have no hesitations in recommending anyone that wants to do business with Envirofan this way. They are a trustworthy company as my experience has shown.

Chris C.

…the fans I ordered from you dealt with our damp problem brilliantly. For a while, the musty smell would come back if we had heavy rain, but the fans always got on top of it very quickly… I’m delighted I went ahead and equally happy with the product itself. Thanks again for your assistance,

Public announcement: buyers beware! Some ventilation and pest management companies attempt to beguile the Australian home-owner with unverified fan-forced vents; unlike the EF range exclusive to Envirofan. Furthermore, these same companies will tell you that they are exclusively licensed to install sub-floor ventilation systems. As of October 2016, your state-wide Fair Trading and Services office will support that no such license exists. You can rest assured your EF fan-forced vent purchase can be safely installed by your preferred local tradesperson, be they a builder, electrician, plumber, pest controller, or other. Avoid companies that will jump at the chance to use your home to test their products. If in doubt, contact Envirofan today!
