A year and 4 days ago, we moved into a brand new house. Installed already was a Venmar AVS air exchanger. Immediately we found that the house always felt cold. Being a newly constructed house, and our first winter in the house, we thought that we just needed to 'let the house warm up' and remove the humidity. We left the air exchanger on the setting that was recommended by the installer. We found that the house, and basement especially always felt cold. The windows constantly have condensation on them, and it is difficult to breathe. We asked many questions and had technicians in to be sure everything was working properly. During the summer months, we found the opposite. The house always felt too hot and our AC could not keep up with cooling the house. Again, we had it inspected and they determined that our AC unit was the correct size for our one-story bungalow and that we should have no problems. Now this winter, we have been feeling the same coolness throughout the house. Upon closer inspection by my husband, he found that the 'Fresh' air pipe that comes from the air exchanger was not connected to ANYTHING. It is blowing cold air from outside directly into our basement. The company has a technician coming to the house tomorrow, and I want to be educated before he comes. Any thoughts? Could this lack of fresh air being distributed in an air-tight house also be the problem that has been causing my son and I to be sick so often?
