Frequently Asked Questions

What is an HRV and do I have one?

A heat recovery ventilator exchanges stale indoor air for fresh outdoor air while recovering heat. It's usually a box near the furnace with two insulated ducts running to the outside wall. Many newer Calgary homes have one.

Why are my windows covered in condensation in winter?

Usually indoor humidity is too high for the outdoor temperature, and the house isn't getting enough ventilation. Running an HRV correctly and using bathroom and kitchen fans normally helps. We can check whether your ventilation is working as it should.

How often should an HRV be serviced?

Filters and the core need regular cleaning, often every few months, according to the manufacturer's manual. A yearly professional check is a good idea, and it fits naturally with a furnace tune-up.

Can you add ductwork for my basement development?

Yes. We add and modify duct runs for renovations and basement developments so new rooms get proper heating and airflow.
