We got ours installed in February. i thought we probably wouldn't notice anything until Winter. It was really humid over Summer and the fabric on our couch and chairs felt wet. It dried out in about three weeks. We also haven't needed the heater on as much. When the gas heater is on I noticed it  doesn't need to go as often as the room is warmer.

Having two HRV units is wonderful covering three bedrooms, living and dining room. Our old damp, dingy house is now a cozy, warm and scented, yes scented, as I hang fragrances above the fans. A plug-in Ambi-Pur with vanilla and jasmine. HRV has also turned our house into a sweet smelling garden of your choice and I used to have bad asthma as our home use to smell musty. Thank you Harvey, good dog

Since we bought our place winters had been hard with build up of condensation on the ranch sliders. There would be tears and big puddles every morning during the winter months. It was that bad the build up of moisture in the house we would get mold on clothing in the bottom draws, shoes in the wardrobe and on the bottom of the curtains. We installed a heat pump when we moved in but that had no affect on the moisture build up. We had hear of HRV and thought how can it work during the winter months when there is very little heat in the day to heat the roof. . . But I got to eat my words. The moment it was fitted and turned on you could taste the cleaner, dryer air in the house and winter came around and the house has stayed dry ever since we had the system fitted. Cleaner, Dryer and Warmer air has made a big difference to our health and life. Even in the winter months A Bonus it will cool the house down during the hot muggy summer nights

Before we got an HRV system we had mold growing in our wardrobes and window sills. Not to mention the really bad condensation. Now we have HRV we don't get any of those problems. Its warm and dry in winter and more comfortable in summer Since we got HRV our family has seen the improvements it has made to the house and have all looked into getting it for themselves. It has truely made a difference.

Before we got our HRV my two young boys were always getting sick with colds and Flu. We called HRV and got a saleman to come and explain to us how it worked. When he checked the temp in our lounge it was 22 and when he went down to the boys bedroom it was only 14. Now we have HRV the house is one temp in every room and no condensation or sick kids. You cant put a price on that.
