From day one the unit did not perform as discussed with the sales rep. We were told the unit would be big enough for the size of the house and would only need one fan. Being the case, this was more economical than your competitors. However, we have had the technician return on multiple occasions to try and make the unit more efficient. It did not get rid of condensation in the winter and the summer kit is virtually useless. Turns out a single fan is not sufficient for the size of the house. If we were informed of this from the start then we may have gone elsewhere. I am expecting this problem to be resolved at no additional costs to us. Look forward to your response. Regards Paul
