Sealing and insulating homes reduces energy loss but also traps pollutants and moisture. Experts recommend at least eight air exchanges per day, yet many homes achieve only five or fewer. This can lead to “sick house syndrome”, where indoor air becomes stale and contaminated.

Heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) solve this problem by exhausting stale air and bringing in fresh outdoor air through a heat exchanger. These systems recover up to 85 % of the heat from the outgoing air, so homeowners get fresh air without high heating bills. During summer, the exchanger works in reverse to expel heat from incoming air ERVs also moderate humidity, ensuring that the incoming air isn’t too dry in winter or too humid in summer.

A balanced ventilation system benefits your family’s health by expelling pollutants such as dust, mould spores and volatile organic compounds while preventing pressure imbalances that can draw in radon or moisture. Additional advantages include quiet operation, low maintenance and long service life.
