Proper sizing is key, with technicians using CFM (Cubic Feet per Minute) to ensure the unit coordinates seamlessly with your existing HVAC. Our comprehensive service includes a full assessment, expert installation, and commissioning. We also address common issues like improper sizing and duct leaks, and offer seasonal tune-ups to maximize energy savings and guarantee long-term comfort and efficiency.

HRV Systems in Washougal, WA

Indoor air quality matters year-round in Washougal. With cool, wet winters, humid spring conditions, and occasional summer wildfire smoke from inland fires, homes here face unique ventilation challenges. An IAQ-focused Heat Recovery Ventilator (HRV) brings fresh outdoor air into your home while recovering heat from exhausted indoor air, keeping your home healthy and energy efficient.

What an HRV does and why it helps Washougal homes

An HRV exchanges stale indoor air for fresh outdoor air while transferring heat from the outgoing stream to the incoming stream. In cold months this returns most of the home’s heat, reducing the heating load. In humid conditions HRVs help control indoor moisture by diluting indoor pollutants and reducing condensation risk that can lead to mold in basements and attics. During wildfire smoke events, an HRV combined with proper filtration provides controlled ventilation while reducing particle entry compared to opening windows.

Key benefits for Washougal homes:

• Improved moisture control in damp winters and springs
• Fresh indoor air without losing heating energy
• Better control of outdoor pollutants, pollen, and smoke
• Reduced condensation and mold risk in older, tighter homes

Common IAQ HRV issues in Washougal and how they show up

Understanding typical problems helps homeowners choose the right system and service plan.

• Improper sizing or undersized unit: Leads to insufficient fresh air, stale indoor air, or excessive noise when running at high speed.
• Poor integration with existing HVAC: Unbalanced systems can cause pressure problems, drafts, or inefficient heat recovery.
• Clogged filters or cores: Reduce airflow and recovery efficiency; common when homes have pets, construction dust, or nearby vegetation.
• Blocked intake/exhaust vents: Leaves the unit starved for outdoor air or unable to discharge, reducing effectiveness.
• Condensate or frost issues: In cold, damp months, insufficient drainage or frost control can cause performance problems.
• Duct leakage and poor routing: Lost recovered heat and uneven ventilation in rooms furthest from the unit.
• Incorrect control setup: Continuous ventilation when not needed or failure to adjust for smoke events.

System sizing and integration with existing HVAC

Proper sizing is essential. HRV capacity is measured in CFM (cubic feet per minute) and should be selected based on home size, occupancy, and airtightness. A tighter, newer home needs less continuous ventilation per square foot but benefits from balanced recovery because it traps indoor pollutants. Typical considerations include:

• Square footage and number of bedrooms to estimate baseline ventilation needs
• Home airtightness or recent upgrades (insulation, windows, air sealing)
• Existing HVAC layout and available duct space
• Balance between continuous low-speed ventilation and intermittent higher-speed boost for events

Integration options:

• Dedicated ducted HRV with supply and exhaust runs to targeted rooms
• Connection into existing ductwork near the furnace or air handler, with careful balancing to avoid pressure imbalances
• Controls that work with thermostats, humidity sensors, or standalone timers for coordinated operation
• Filtration upgrades to complement the HRV during smoke events

An experienced assessment will match CFM to occupancy and ensure the HRV works in harmony with your furnace or heat pump.

Typical installation steps

Installation is a multi-step, code-aware process that ensures performance and long-term reliability.

1. Home assessment and load review to determine size and best location
2. Choose unit location (basement, mechanical closet, or attic) with easy access for service
3. Install exterior intake and exhaust terminations with proper clearances and insect screens
4. Run ductwork: balanced supply and exhaust runs to core living spaces and moisture-prone areas
5. Electrical hookup and control wiring; integrate with existing HVAC controls if applicable
6. Commissioning: airflow balancing, control set-up, frost control check, and noise evaluation
7. Owner orientation on filter access, normal operation modes, and seasonal adjustments

Proper commissioning is crucial. Balancing the system and confirming control logic prevents pressure problems and ensures expected heat recovery performance.

Maintenance needs and recommended schedule

Routine maintenance keeps an HRV working efficiently and extends its life.

• Filters: Inspect every month during heavy use; replace or clean every 3 months on average.
• Core exchange element: Clean annually or as recommended; more frequently in dusty or high-pollen seasons.
• Exterior grilles: Clear debris, leaves, and snow from intake/exhaust terminations regularly.
• Condensate drains: Verify drainage and clean annually to prevent clogs.
• Fan motors and belts: Check condition during annual service visits.
• Frost control and defrost components: Inspect before each cold season to avoid winter performance loss.

A yearly professional check-up plus routine homeowner filter care typically prevents most issues and maintains energy performance.

Expected energy savings and performance

HRVs reclaim a large portion of the thermal energy that would otherwise be lost through ventilation. Typical energy recovery rates are substantial compared to simple ventilation or opening windows:

• Heat recovery typically returns 60 to 80 percent of the heat from exhausted air, depending on unit quality and installation
• Lower heating demand in fall and winter as fresh air is pre-warmed
• Less need for dehumidification in spring and summer by providing controlled ventilation rather than uncontrolled moisture intrusion

In Washougal, where heating dominates energy use for much of the year, an HRV can noticeably lower the energy penalty of ventilation while improving comfort and indoor air quality. Exact savings depend on local heating systems, fuel type, and home envelope tightness.

Service options available for Washougal homeowners

Service offerings commonly available include:

• On-site IAQ assessments to recommend HRV versus ERV and proper capacity
• New construction design and HRV specification to integrate with HVAC plans
• Retrofit solutions for homes with existing duct systems or tight spaces
• Integration with heat pumps and furnaces for coordinated operation
• Annual maintenance plans that include filter changes, core cleaning, and performance checks
• Seasonal tune-ups focused on frost control, drain checks, and intake protection

An IAQ-focused HRV is a practical solution for Washougal homes that need reliable ventilation without sacrificing energy efficiency. Proper sizing, professional integration, and routine maintenance are the keys to long-term performance - improved comfort, consistent moisture control, and cleaner indoor air. For homes impacted by damp winters or intermittent smoke, an HRV helps maintain a healthier indoor environment while keeping heating energy in the house where it belongs.
