We had laminate floors installed and had some peaking, as the weather got cooler,the peaking went almost away. Is this a problem

That is not normal. My guess is that the installers did not leave the quarter inch expanding room around the edges. If I were you I'd complain to the installer - and take some pictures in case the problem is not apparent when they come to check it out.

I agree, sounds like a bad installation. Start calling your installer. Do you know how to test the humidity level in your home?
