Installation of HRV ProAir
ducting of the HVAC. (During summer months, the outdoor humidity supplied through the HRV may cause condensation on interior surfaces of the HVAC equipment and the supply plenum and ducting. These surfaces will be around 60°F, and outdoor air dew points in the summer in much of the United States are well above this temperature.

Heat Recovery Ventilation (HRV) Definition, Advantages & Installation
If the HRV is installed such that the homeowner may turn off the HRV during the winter, we recommend installing a motorized damper between the HRV's supply air and the furnace's return air duct that closes when the HRV is not operating. See wiring diagram (figure 1).
HEAT RECOVERY VENTILATOR How to Install An HRV or ERV Yourself
Heat recovery ventilation (HRV) and energy recovery ventilation (ERV) (sometimes also called mechanical ventilation with heat recovery, or MVHR) offer a solution, bringing fresh air into your home without letting the heat escape. Let's take a closer look at how they work! Photo: The inside of a typical heat recovery ventilation (HRV) system.

This guide will assist designers, developers, builders, renovators and owners gain a better understanding of heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) and how they can support healthy indoor living environments in single family, semi‐detached and row housing (herein referred to as "houses"), including: Why venti.
Utilizing an HRV System for Ventilation in My Energy Efficient Home
By Scott Gibson | October 8, 2021. The core of an energy-recovery ventilator allows the transfer of both heat and moisture between exhaust and supply air streams. Along with heat-recovery ventilators, these appliances provide balanced ventilation systems and reduce the energy costs of providing fresh indoor air. Photo courtesy RenewAire.

Heat Recovery Ventilation (HRV) Definition, Advantages & Installation
Heat Recovery Ventilation (HRV) proposes a method to bring fresh air into your home without allowing the heat runaway. Air leakage makes homes more problematic to heat. Not only this is big trouble for the environment, but also heating an unsealed house needs more cost and time.

Flexible ducting must only be used in short lengths of less than 30 cm. A short length, pulled taut, is often used to connect rigid ducting to the fan unit or to an air valve - it helps to reduce noise transfer. (Flexible ducting should not be used to form bends, though in practice there are plenty of bad examples of this.) Using flexible ducting

Cococchio Thought I'd chime in as my thinking has evolved on this some what. First, I'll hold up everything Martin said below. The root problem here is really that residential HVAC is a complete mess. Contractors do minimal design often incorrectly and commissioning is non existent. It's no wondering why ventilation systems aren't working.
