ERV installation in Los Angeles

Modern homes are built tighter for energy efficiency — which means less fresh air exchange and more indoor air pollutant buildup. An Energy Recovery Ventilator (ERV) solves this by bringing in fresh outdoor air while recovering 70–80% of the energy from the outgoing stale air. The result: fresh air without the heating or cooling cost penalty.

HVAC in LA installs ERV systems integrated with your existing HVAC ductwork. We size the unit to your home's volume and occupancy, confirm it meets California's Title 24 ventilation requirements, and configure controls that work with your existing thermostat or smart home system.

Why you might need an ERV in LA

New construction or recent weatherization — tight building envelope, insufficient natural ventilation
Elevated CO₂ levels (above 1,000 ppm) causing fatigue or reduced cognitive performance
VOC buildup from new construction materials, furniture, or cleaning products
Title 24 ventilation compliance for new construction or major renovation
Year-round comfort without opening windows (wildfire smoke, allergies, noise)

ERV Installation FAQs

What is the difference between an ERV and an HRV?

Both recover heat energy from exhaust air. An ERV also transfers moisture between the air streams — in dry climates like LA winters, this helps maintain indoor humidity. An HRV does not transfer moisture. For most LA applications, an ERV is the better choice.

Do I need an ERV if I have an air purifier?

They solve different problems. An air purifier cleans recirculated indoor air. An ERV brings in fresh outdoor air to reduce CO₂, VOCs, and other pollutants that can only be diluted with fresh air, not filtered. Many complete IAQ systems use both.

Will an ERV increase my energy bills?

By 5–10% over a sealed-tight home, but the energy recovered (70–80% of what you would otherwise spend conditioning outdoor air) makes it much more efficient than simply opening windows. In practice, most homeowners see minimal bill impact.

Is an ERV required for my new build in Los Angeles?

California Title 24 requires mechanical ventilation in new residential construction. An ERV or HRV is one of the approved compliance paths. We provide Title 24 documentation as part of every ERV installation.
