Heat recovery ventilators (HRVs) are the lungs of a modern, airtight home: they pull stale air out and pull fresh air in while recovering heat from the exhaust, so ventilating in winter does not cost a fortune. When the unit fails, window condensation, stuffy air, and lingering odours usually follow.
Call Durham HVAC Connect and we'll connect you with an HVAC professional serving Durham Region who installs and services HRVs. Mention whether the unit is original to the home, what symptoms you are seeing — condensation, musty air, a fan that never stops — and whether it has been serviced recently.
HRV care is mostly about the filters, the core, and balance. The professional will clean or replace the filters and the energy-recovery core, clear the exterior intake and exhaust vents of debris, check the fan and motor, and confirm the unit is balanced so it neither over-pressurizes nor starves the home of air. Malfunctions often show up as a fan stuck on or off, ice forming in the core in deep winter, or a unit whose controls have stopped responding. A professional who has worked on these systems can troubleshoot the controls and motors, which are the parts that wear out.
