Our Question of the Week focuses on a query from “DC,” a Texas reader who wants to know which residential ventilation system will provide the “most bang for the buck.”
DC knows that a tight home requires a mechanical ventilation system to provide fresh air. But how does one choose among the bewildering array of options? And are there any performance advantages to expensive ventilation systems?
Armando Cobo recommends a balanced ventilation system without heat recovery, explaining, “I would spend NO money on an HRV or ERV — you do not need it in your climate.”
Martin Holladay recommends a central-fan-integrated supply ventilation system. Such a system requires an AirCycler control wired to a motorized damper controlling the flow of fresh outdoor air to the return plenum of the home’s furnace.
Robert Riversong recommends a balanced system with an ERV or a supply-only system.
