blowersVentilation Fans and equipment are produced by various manufacturers from all over the world. Each with their own characteristics such as Dimensions, Noise Levels, Power Consumption, Air Volume Movement etcetera etcetera. This is why it is so important to assess and analyse each ventilation project on its own merits. It simply cannot be assessed by looking at your house on Google Earth, asking a couple of questions and providing advice and a quote over the phone. It is of utmost importance to view the surroundings, conditions, structure, take accurate volume measurements amongst other things before determining which equipment will achieve the best results.

Positive or Negative Pressure

There are only two types of ventilation. Positive and Negative. Positive means to PUSH air into the offending area and Negative PULLs or Extracts air. Careful evaluation is required before doing either. Such as, where is the old air being pushed out going too? Or where is the new air coming from that will replace the old air being extracted? Sounds complicated right? It often is, which is why it is so important to take the time to assess each and every ventilation project individually.

Passive Ventilation

Take a stroll around your home. You will more than most likely see quite a few vents or holes in the walls either towards the top or bottom or both. These are called Passive Vents. We have been building them into our structures for centuries. Doing so is an attempt at some sort of ventilation, either to the sub-floor of the property, the walls cavities and even attempting to ventilate inside the dwelling (which by the way, used to be a mandatory requirement back in the 50’s, 60’s & 70’s). These holes, grilles or vents are expected to allow enough fresh are to flow from outside through the area and then make its way out via the others. Comical really! Without mechanical assistance this is not going to provide anywhere near an adequate air exchange to ward off moisture, mould and nasty little pests like Termites.

Grilles Diffusers Ducting & Accessories

There’s a reason why there are so many of these to choose from. Determining which are the best to use can only be accomplished through thorough assessment and evaluation. Some grilles, if incorrectly chosen, will create noise levels higher than that of the mechanics behind them. Ducting may need to be insulated and acoustically designed or chosen for its ability to carry temperature and air flow rates.

What others are saying....

Margaret W - Woy Woy NSW

"Central Coast Ventilation provided us with the correct advice for our problem and because of the way they handled that, we gave them the job. Now our damp problem has gone completely and we don't have to put up with the mould any longer and we are so thrilled about that.

Colin came highly recommended and I can now see why and will also be recommending him to others"

The advice and professionalism you gave to us was second to none because now we don't have that damp, dank smell lingering any more! I will certainly be recommending you to anyone who asks in the future!"

"We recently had sub floor ventilation installed by Central Coast Ventilation. When Colin quoted we were very impressed by his expertise and knowledge of technical data which was clearly explained. The cost was fair and competitive and the unit was installed efficiently together with a follow up call to check that we were completely satisfied. We are very pleased with all aspects of the work done and highly recommend the company to anyone requiring ventilation services for their home or business."

"We recently chose Central Coast Ventilation to install our sub floor ventilation. When Colin arrived to give us a quote we found him to be prompt and knowledgeable and listened to our concerns. His quote was reasonable and fair and we felt comfortable with his recommendations. On the day of installation the installers were on time, friendly and helpful. The work was carried out efficiently and with care.
It is now one month since installation and we are very happy with the results. Colin has also rung us for a follow up to hear of any concerns or problems to which there were none. We would not hesitate to recommend Central Coast Ventilation because of our positive experience."
