Best thing we ever did. I used to squeegie every window in the house every morning which froze my poor little fingers. Then I could have my shower to warm up. We thought the HRV system would help with the condensation, but it exceeded our expectations and removed it entirely!  Friends come round and comment how warm our house is on a winters day - we have no heating on. Just awesome.

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

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

The first thing we did when we bought our house in town was to install an HRV.  We have no condensation and best of all I don't get those annoying tickly throats that I used to get every winter.  We have less colds and coughs since getting the HRV.  When the roof gets hot the HRV blows the warm air into the house meaning that we don't have to use our heating as much.

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.
