Im pretty sure I know the answer, but want to confirm with someone who has a strong background in HVAC.
Newer house inspected ( 5yrs old) The home has an HRV tied into the return of the furnace. between the boot and the duct, they left a 2" gap (photo). The home also has no return air at all, other then this source. I’m assuming the gap is because the furnace was starving for air. Has anybody seen this before? I usually contact my HVAC buddy’s, but can’t get a hold of anybody.
Your help would be appreciated.
