With modern building practices, having an HRV (heat recovery ventilator) or ERV (energy recovery ventilator) in your home is vital to balanced and healthy air quality. The supply of filtered fresh air a HRV/ERV brings into the home curbs problems that aggravate health and comfort.  We can help you choose the best model to ventilate any problem materials from the air, keeping your family healthy.

Our Outstanding Service

When you use Hy-Mark, your plumbing and HVAC systems will only be installed and serviced by licensed professionals. We back our equipment with labour warranties because we take pride and confidence in our work.

The Hy-Mark Difference

It’s all about innovation. That’s why in addition to sheet metal, our fabrication shop works with duct board to create virtually silent, customized ducts for your home. The duct board material is a fiberglass insulated, foil lined sheet that we cut and shape to create the most airtight, noiseless ventilation system possible. The result is a quieter system, less condensation, reduced air loss, and cost savings in energy usage.
