ERV, also known as Energy Recovery Ventilator, is an integral part of a home’s ventilation system. These systems are designed to improve indoor air quality by bringing fresh outdoor air while exhausting stale indoor air. They work by transferring the energy from the outgoing exhaust air to the incoming fresh air, which helps to precondition the fresh air and reduce the load on the building’s Make-Up Air & HVAC system, saving 60 to 70% of the energy of your outgoing air.
According to Ontario Building Code 2020 (CBC), section 9, all new construction condo buildings must be equipped with an ERV system for energy-saving purposes.
There are two types of ERVs in Toronto condo buildings.
1. ERVs integrated with Fan Coils & Heat Pumps
2. Independent ERV systems.
Regular maintenance and upkeep are essential for ensuring the proper operation of an ERV. The following is a technical guide to help you understand the maintenance and operation of an ERV.
1. Filter Replacement: The filters are recommended to be cleaned or replaced quarterly or semi-annually to ensure optimal airflow and prevent contaminants from entering the system. There are two filters to be replaced during the maintenance visit.
2. Heat exchanger (The Core): This component transfers energy from the outgoing exhaust air to the incoming fresh air. It should be inspected and cleaned once a year to ensure that it is functioning correctly and that dirt or other contaminants are not building up.
3. Motor and fan assembly: The motor and fan are responsible for moving air through the system. They should be inspected and serviced as needed to ensure that they are functioning correctly and that there is no noise, damage or wear & tear.
4. ERV Controls: These components regulate airflow via a wall-mount control system. ERVs are designed to run continually at low speeds. Some units are equipped with wall-mounted timers and speed controls. The switch offers 20, 40, and 60-minute ventilation options. They should be inspected and adjusted to ensure that they function correctly and the system operates optimally.
5. Drain pans and condensate lines: These components collect and remove moisture from the system, just like fan coils. They should be inspected and cleaned periodically to ensure that they are functioning properly and that dirt or other contaminants are not building up.
Importance of ERV Air Balancing In Condos
When an ERV is not balanced, it can cause imbalances in air distribution within the condo space. This can result in areas that are too hot or too cold or where the air is not effectively circulated. As a result, building the central HVAC system must work harder to maintain the desired temperature, leading to increased energy consumption.
In addition to increased energy costs, improper air balancing can negatively impact indoor air quality, such as excessive moisture, mould growth or the buildup of pollutants. Building owners & managers should prioritize air balancing and regular ERV maintenance to ensure optimal building performance.
Schedule Annual ERV Maintenance
Although ERV ownership is transferred to individual owners, it is recommended that semi-annual ERV maintenance be provided along with regular in-suite HVAC maintenance. If you have any concerns or questions about the operation or maintenance of your ERV, please schedule an inspection with our team today to get a full report.
