ERV Ventilation System for Hot-Humid Climate
My old 3500 sf house is slowly getting renovated and retrofitted with spray foam to make it air tight. I need a complete new AC system and the hvac contractor talked me into a ductless mini split system since I have limited space for ductwork (the remodel will take away all attic and crawl spaces and turn them into usable living space). I’m on board with that.
In addition, I was originally interested in installing an ERV for ventilation. The contractor says that’s a bad idea since I’m in Houston (very hot and humid). He thinks a 95 pint dehumidifier with mechanical damper and fresh air intake is a better option.
Does that sound correct? Will that give me enough air exchange to keep the house from depressurizing? Would other ways of ventilation, like bathroom exhaust fans for instance, still be necessary with that set up?
