What is the cost of having an HRV system cleaned after construction in my Ottawa home?

HRV system cleaning after construction in Ottawa typically costs between $400 and $800 for a residential home, with most homeowners paying around $600 for a thorough post-construction cleaning. This specialized service is essential after any major renovation or new construction because Ottawa's extreme winter conditions mean your Heat Recovery Ventilator runs constantly during the 5-6 month heating season, and construction dust gets deeply embedded in the system's heat exchanger core, filters, and ductwork.

Why HRV Cleaning is Critical After Construction

Post-construction HRV cleaning is more complex than standard HVAC duct cleaning because the heat recovery ventilator has unique components that trap fine construction particles. The heat exchanger core, which transfers heat between incoming fresh air and outgoing stale air, becomes clogged with drywall dust, sawdust, and concrete particles. During Ottawa's heating season when indoor humidity drops to 15-20%, this construction dust becomes extremely fine and airborne, settling throughout your HRV system. The system's continuous operation during winter construction means contaminated air circulates throughout your entire home until the HRV is properly cleaned.

Professional HRV cleaning after construction includes removing and washing the heat exchanger core, replacing all filters, cleaning intake and exhaust ducts, sanitizing the unit housing, and testing airflow balance. The heat exchanger core requires careful handling because it's made of thin aluminum or plastic sheets that can be damaged by aggressive cleaning. Contractors use specialized low-pressure washing techniques and mild detergents to clean the core without compromising its efficiency.

In Ottawa's climate, your HRV system is essential for maintaining indoor air quality while conserving energy. A contaminated system after construction will reduce heat recovery efficiency by 20-40% and continuously recirculate construction dust particles throughout your home. The Ontario Building Code requires mechanical ventilation in new homes, making HRV cleaning a necessary step before occupancy permits are issued.

Timing matters significantly in Ottawa - schedule HRV cleaning after all dusty construction work is complete but before final occupancy. Spring is the busiest season for this service as winter-delayed projects rush to completion. Expect 2-4 week booking delays from April through June. The cleaning process takes 3-5 hours and requires shutting down your ventilation system, so plan accordingly during extreme weather periods.
