Benefits:

• Brings in fresh outside air
• Pre-Heats & Cools Outside Air
• Helps Lower Energy Costs
• Transfers Hot/Cool Inside Air To The Fresh Air Passing Through The Unit

What does a HRV do? (Click To Expand)

A heat recovery ventilator (HRV) brings in fresh air from the outside, preheats the incoming air during the winter and precools the incoming air during the summer. It can provide clean fresh air every day while helping to keep energy costs low. One set of ducts collects stale moist air from the kitchen, laundry and bathrooms. This stale contaminated air passes through the HRV unit and is exhausted to the outside. The other ducting system draws in fresh clean air from outdoors through the HRV unit. As the two air streams pass each other within the heat exchanger core, heat is transferred from the outgoing stale air to the fresh incoming air. There is no mixing of air streams.

Our Method

1. Our Technicians will inspect your HRV to ensure that it is working properly. If any abnormalities are discovered, the technician will be sure to inform the customer.
2. We remove the core and the filters which are set aside for cleaning later.
3. The vacuum hose is securely installed into the HRV to create negative pressure on the whole ducting system.
4. The vacuum and air compressor are turned on.
5. We then clean the inside of the HRV including the motors, the filters, the core and 4 main intake and exhaust air ducts with the vacuum continuously running.
6. We will then wipe clean the inside of the HRV with cleaner and disinfectant before putting the core and filters back inside.
7. The HRV will be turned on and the technician will make sure that the HRV is cycling properly.
8. Any messes that are made around the diffusers are vacuumed and cleaned up.
