HRV Installation in St. Paul — Heat Recovery Ventilators
St. Paul's older housing stock and newer tight builds both struggle with winter indoor air: condensation on windows, lingering odors, and rooms that feel closed-in. An HRV (heat recovery ventilator) exchanges stale indoor air for fresh outdoor air while recovering the heat — so you get ventilation without dumping your furnace heat outside. Furnace Direct installs and replaces HRVs across St. Paul and the east metro.
Why St. Paul homeowners choose HRVs
East metro winters are hard on sealed homes. When St. Paul houses get new windows or insulation upgrades, humidity from daily living has nowhere to escape — fogged glass and musty basements follow. An HRV recovers heat from exhaust air but lets moisture leave the house, which matches Minnesota's cold, dry outdoor climate. That's the opposite of an ERV, which would keep more moisture indoors.
What an HRV install involves
New installation
For a new HRV in St. Paul we plan duct routes that fit your layout, hang the unit, connect drain and controls, and balance supply vs. exhaust so the system performs as designed — not just 'turned on.'
Replacing an old unit
Replacing a failing air exchanger in St. Paul is often a same-day swap when ducting is sound. We remove the old core unit, install the new HRV, and rebalance so you're not left with uneven airflow.
- Windows fog up or drip with condensation in winter
- The house feels stuffy, or cooking and pet odors linger
- Indoor humidity feels high in winter or the air feels stale
- Your current air exchanger is old, noisy, or the core is shot
- You just tightened the house up (new windows, insulation, spray foam) and comfort got worse
