Fantech Ventilation Systems in Phoenix

Not before the duct system has been measured. Most rooms that never cool have a duct sizing, leakage or return problem, and a booster masks it while adding a motor that will fail in attic heat. Our field note on the one room that never cools explains the usual causes.

The seed catalog lists them among Fantech's ERV, HRV and ventilation families without further detail, and we publish only what we have verified. Which family a given unit belongs to, and what it is rated to deliver, are research pending until a technician reads the nameplate.

Some are installed on a continuous low-speed setting by design, particularly in tight homes that rely on the fan for baseline ventilation. Others run constantly because a timer or control failed. If it was quiet before and is not now, or you cannot find a switch that controls it, have it checked.

Yes, that is a common inline configuration: one remote fan with ducts to two or more grilles, each with its own backdraft damper. When one damper sticks, air can move between bathrooms instead of outdoors. It is repairable and worth checking if one bathroom smells like the other.

We stock common motors, dampers and filters for ventilation equipment generally, not a brand-specific inventory. Brand-specific cores and controls are sourced as needed. Parts availability for older generations is research pending on a case-by-case basis, and we will tell you before ordering.

Usually not until the house has been sealed. A leaky block-and-stucco home already exchanges plenty of air with the outdoors. Spend on duct sealing and attic work first, then revisit ventilation if the house feels closed up afterward.
