Energy Recovery Ventilators

An energy recovery ventilator has numerous advantages. Why should you install an ERV? Here are a few reasons to think about it.

  • reduce carbon footprint

  • lower utility bills

  • improve indoor air quality

  • prolong the lifetime of HVAC system

  • conclusion

1. Reduce carbon footprint

In accordance with the global goal of carbon neutrality and temperature management of 1.5°C, energy recovery ventilation can make a significant contribution to lowering the amount of carbon emissions produced in your home. This is because their design is incredibly efficient. The system is made up of two fans; one is used to exhaust stale air and the other to draw in outside fresh air. During this process, around 82% of the old heat is retained.

2. Lower utility bills

An ERV contains a heat exchanger that can either heat or cool the incoming air. In the winter, it transfers heat from the outgoing air to the incoming air, and in the summer, the process is reversed. This system can transfer approximately 80% of the heat energy from the stale, outgoing air to the fresh, incoming air. It saves energy and lowers your utility bills by preconditioning the incoming air. An energy recovery ventilator is an investment, but it will pay for itself in lower energy costs over time. If your monthly bills are rising, consider installing an ERV system.

3. Improve indoor air quality

ERV can improve indoor air quality in three aspects: healthy, clean, and comfortable.

Healthy: sufficient oxygen

Nowadays homes are built well-insulated, which makes them more energy efficient. However, it makes indoor air stuffy with carbon dioxide building up. To complement the air tightness, we can use ERVs to act as “lungs” to distribute oxygen sufficient air throughout the house. So we can always breathe fresh and breezy air in our house.

Clean: goodbye pollutants 

Once you sneeze and sniffle a lot inside the building, it means the IAQ (indoor air quality) becomes really bad. Energy recovery ventilators has filters that block out incoming fresh air so you won’t be exposed to outdoor pollutants like dust, pollen, and other allergens. While expelling indoor stale air, ERVs also remove indoor pollutants like excess moisture, moulds, VOC and bacteria. With clean air, you’ll be able to breathe easier, sleep better.

Comfortable: stable indoor temperature

If you ventilate your house by natural ways such as opening doors or windows, the indoor temperature will change suddenly and dramatically, especially in summer or winter, which is harmful to human beings. An ERV offers your home fresh air at a temperature that is close to the air temperature already inside. You will feel more comfortable without rapid huge changes in temperature.

4. prolong the lifetime of HVAC system

An ERV can keep your heater and air conditioner from working at full capacity, thereby reducing wear and tear. How does it accomplish that? An ERV pretreats the incoming fresh air, which helps reduce the amount of work your HVAC system has to do. As a result, your heater or air conditioner doesn't have to work so hard to keep the temperature in your house stable. With less work to do, the rate of wear and tear of your HVAC systems reduces.  


We can conclude that it’s a wise decision to invest in energy recovery ventilator. It can help you save energy, improve the air quality in your home, and extend the life of your HVAC system. If you have additional ideas to share, please click the button on the right side and let's chat.
