Do I need an ERV (Energy Recovery Ventilator) in Utah?
ERVs make sense in any tightly-sealed Utah home — especially newer builds (post-2015 with blower-door scores under 3 ACH50). They bring in fresh air without losing the winter humidity or summer cooling, and they filter out wildfire smoke and pollen.

An ERV exchanges stale indoor air for fresh outdoor air while recovering 75-85% of the temperature and humidity you'd otherwise lose. In tight new Utah homes (blower-door tests under 3 ACH50), the house doesn't get enough natural ventilation and indoor CO2, VOCs, and odors build up.
An ERV provides constant, filtered fresh air — which also means the incoming air goes through a filter that catches wildfire smoke, pollen, and dust before it enters your home. Older, leakier Utah homes benefit less from an ERV because they already exchange air through leaks (though they lose more energy doing so).
The decision point is: is your home airtight? If you get condensation on your windows regularly in winter, your house might actually be too tight and an ERV is the right move.
