Frequently Asked Questions

  • What is an ERV or HRV system?

    ERV (Energy Recovery Ventilator) and HRV (Heat Recovery Ventilator) systems are designed to improve indoor air quality by exchanging stale indoor air with fresh outdoor air while recovering energy from the outgoing air. These systems maintain comfortable indoor temperatures, reduce humidity issues, and enhance overall air quality in homes and small commercial spaces.

  • How do ERV and HRV systems benefit my home or business?

    ERV and HRV systems help:

    • Maintain healthy indoor air quality by reducing pollutants and allergens 
    • Improve energy efficiency by transferring heat or cooling between incoming and outgoing air 
    • Control humidity levels for greater comfort 
    • Reduce strain on HVAC systems by balancing airflow

    Yes. 2 Guys Ducting installs and services ERV and HRV systems for both homes and small businesses. We evaluate your building’s layout, airflow needs, and indoor air quality goals to recommend the most efficient and effective solution.

  • How often should ERV/HRV systems be maintained?

    Regular maintenance ensures peak efficiency and longevity. Filters should be checked or replaced every 3–6 months, and the system should be inspected annually by a qualified technician. 2 Guys Ducting provides maintenance, cleaning, and service to keep your ERV or HRV system operating optimally.
