Our heat pump is in a hall closet with a small grille. Is that why it keeps freezing up?

Quite possibly. A heat pump needs a certain amount of air across the indoor coil, and a small return starves it. We measure airflow and static pressure and tell you whether a bigger grille, a better filter setup or a duct change is the fix.

How often should we change the filter on a Bosch heat pump in a small house?

Look at it monthly and change it when it turns gray, which with a small return can mean every month or two. A clean filter is the cheapest repair you will ever make on this system.

Do you repair Bosch heat pumps in San Pablo apartments and row houses, or only single-family homes?

Both. In a rental or a row house we need the owner's or manager's go-ahead and access to the indoor and outdoor units. The written quote goes to whoever approves the work.

Bosch Home Comfort in San Pablo

Bosch Home Comfort heating and cooling in San Pablo.

More of San Pablo's housing was built between the 1940s and the 1960s than in any other era, and single-family homes share the city with a large number of apartment buildings and row houses. In a small older house the indoor unit may sit in a hall closet or a corner of the garage, where the return grille and filter are smaller than a modern heat pump wants.

Restricted airflow causes a specific set of faults on a Bosch Home Comfort system: a frozen indoor coil in summer, high-pressure trips in winter, a blower that sounds strained. Our technician for San Pablo works out of Benicia. Every visit starts with a $99 diagnostic that is credited toward the repair, and we quote in writing before we fix anything. CSLB #1136642.

Common repairs we handle.

Indoor coil frozen solid in cooling mode. Low airflow lets the indoor coil drop below freezing, and ice spreads until almost no air comes out. We have you switch to fan only to thaw it, then check the filter, return size, blower and charge. Adding refrigerant to an iced coil without finding the cause just hides the problem.
Filter clogging fast in a small return. A small filter handles every bit of air the heat pump moves, so it loads up quickly and the whole system suffers. We check the filter size against the airflow the system needs, and a larger return grille or a deeper filter rack often ends the repeat visits.
High-pressure trip in heating mode. In heat mode the indoor coil does the job of the condenser. Weak airflow there lets pressure climb until the system trips on protection. We measure the temperature rise across the air handler and check the blower, filter and ducts before we suspect the refrigerant circuit.
