Step-by-step DIY guide to choosing, installing, and maintaining HRV systems for healthier indoor air and better energy efficiency in airtight homes.
DIY Guide to HRV Systems: Fresh Air for Energy-Efficient Homes Heat Recovery Ventilation (HRV) systems are an effective way to improve indoor air quality while reducing energy waste in airtight homes. These systems exchange stale indoor air with fresh outdoor air, transferring heat between the two streams to minimize energy loss. This makes HRVs ideal for maintaining comfort and efficiency, especially in colder climates. Key points: - How it works: HRVs use a heat exchanger to pre-warm or pre-cool incoming air, reclaiming 60–95% of heat from outgoing air. - Benefits: Balanced ventilation prevents drafts, moisture buildup, and pollutants like allergens and mold. - Costs: Installation typically ranges from $2,000 to $5,000, with a lifespan of 10–15 years. - DIY potential: Installing an HRV yourself can save on labor costs, but proper setup and maintenance are crucial. If you're looking to improve air quality and energy efficiency in your home, HRV systems are a smart choice. Read on for ...
