I'm not sure if the summers are hotter or I'm just getting older but I find my self thinking seriously about installing A.C. in our off-grid log home. The current swamp cooler we use keeps the house 15 degrees below the outside temperature but when the temps get above 95 degrees, it's no longer pleasant. Would love to hear how you off-gridders are coping with the summer heat. We live in an inland valley of southern California where the summer temps range from 95 to 105 consistently. We only have 120 VAC with no easy way to expand to 240 VAC.
