Ventilation System Repair Near Me in Los Altos, CA

Ventilation system problems in Los Altos, CA don't always announce themselves obviously. The air just gets stuffy, humidity drifts higher or lower than it should, condensation appears on cold surfaces, or fresh-air rooms suddenly feel stale. Most ventilation repairs are simple once the source of the problem is identified.

Common ventilation system repairs include clogged or broken filters in the HRV/ERV, frozen heat-exchange cores in winter, blocked outdoor intake louvers (debris, leaves, insects), failed motors or fan capacitors, condensate drainage issues, control board failures, and damaged ductwork — particularly the outdoor intake and exhaust runs where weather exposure takes a toll.

A qualified technician familiar with HRV/ERV equipment diagnoses the problem by checking airflow at known reference points, inspecting the heat-exchange core for damage or scaling, testing the motors and controls electrically, and confirming the ducting is clear from intake through exhaust. Most issues resolve within a single visit.

In Los Altos, CA winters, frost forming on the HRV/ERV core can be a normal defrost cycle running or a real problem with the defrost system. If the unit is running on defrost more than expected, it shortens the time it's actually ventilating and reduces effectiveness. A repair check confirms whether the defrost is timing properly.

For homes where ventilation seems to have stopped working entirely, the problem is sometimes outside — birds nesting in the exterior cap, insulation displaced over the intake, or rodent damage to the outdoor lines. A complete inspection looks at the outdoor equipment too.
