I had my HRV system installed about 4 yrs ago at a cost of several thousand dollars for a small 3 bedroom house. The sales person was quite aggressive but we had done our research and decided to go with HRV anyway. As it turns out he over sold us and according to him we needed two fan units for a 3 bedroom house of 152m square.
It took two installers about 3 hrs and the equipment they install is really very basic. (air ducting which is super-cheap to buy, two fan units which is only a fan and motor inside a tin box, a control panel and some ceiling ducts and some electrical cabling. Items purchased separately would cost less than $800. But to be fair, cudo's to HRV for their business idea. Just hard to swallow the cost of such an overpriced system. However it fixed my condensation problem right up and I was very happy. But it wasn't long before they were calling to pressure me to have the filters changed. I did some research and found replacement filters online for about half the price of HRV's. I replaced them myself as it’s a very easy job as long as you can manoeuvre in the ceiling space. They kept calling over the space of a couple of months with a very aggressive approach. I can't remember how the conversations went but I was left with a feeling of being hassled rather than being helped. From then on I refused to buy their replacement filters even though they continue to call me about it.
NOW though I received an email from them stating that they are now discontinuing their current HRV systems and are no longer able to support their existing customers who have older HRV systems installed....wait for it......UNLESS we take advantage of their generous offer to upgrade our current HRV to their new model for a discounted rate as we are existing customers. The price of the upgrade?...$2399.00 Takes 2. hours only.
They state in their email that the next generation system costs about $5000-$6000 for non existing customers. WHAT A SCAM!!!
Suffice to say I will not be upgrading.
Thank you for reading this if you got this far.
