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.

When is an ERV or HRV recommended for Thornton homes with high-altitude dry air?

Answer: An ERV or HRV is recommended when mechanical ventilation is needed without losing conditioned air and when occupants want balanced ventilation during long dry winters. Choose systems sized for the home's square footage, and request a contractor who measures ventilation rates and explains frost control or defrost cycles for Colorado winters.

How do I find an IAQ contractor in Thornton experienced with smoke and high-altitude filtration?

Answer: Look for providers who list high-MERV or HEPA-capable whole-home filtration and in-duct UV-C options. Verify credentials such as NADCA membership or NATE certification, and request recent local references showing smoke-season work in Thornton. Ask about filter capture efficiency for PM2.5 and service frequency.

What should I ask about in-duct UV-C light installations in Thornton?

Answer: Ask whether the UV-C system is designed for the duct size and airflow in the home, and whether the installer considers lamp replacement intervals and safety shielding. Request manufacturer specifications, a lamp replacement schedule, and whether the contractor documents pre- and post-install airflow and system access for maintenance.
