Do I need an ERV or an HRV?

Both recover most of the energy from the stale air they exhaust while bringing in filtered fresh air. The difference is moisture: an ERV transfers humidity as well as heat (the right choice in humid Texas and Florida), while an HRV moves heat only (better for cold, dry winters). A tight, stuffy, or newly-sealed home is the main candidate.

How is the right ventilation size determined?

Sizing follows the ASHRAE 62.2 residential ventilation standard, which sets the fresh-air rate from the home's floor area and bedroom count. A good installer calculates that rate rather than guessing — an undersized unit won't clear stale air and an oversized one wastes energy.

Do Altoona homes benefit from ERV or HRV ventilation systems?

Yes. ERV and HRV systems improve fresh air exchange while preserving energy, which helps in Altoona's tight, heat‑conserving homes. They reduce trapped allergens and VOCs from indoor sources. Request a load and airflow assessment to determine whether an ERV or HRV fits the house layout and heating system.

When should Altoona homeowners install a whole‑house dehumidifier?

Install a whole-house dehumidifier if persistent summer humidity causes mold or condensation in living spaces. Altoona's humid summers drive this need, especially in basements and older homes with poor ventilation. Have a technician measure indoor relative humidity before buying. Look for installers who include placement planning and post-install humidity readings.

How do I evaluate whole‑house media filter upgrade options for an Altoona house?

Look for filters sized to the HVAC blower and rated for the target particle size. Altoona homeowners often need upgrades for pollen and mold spores after humid summers. Ask for MERV ratings, expected pressure drop, and whether the contractor will test airflow after installation. Prefer installers who show pre‑ and post‑filter performance figures.
