Look at both sides of the season.
Because a heat pump handles heating and cooling, a useful repair history includes how it performs in both modes. Tell us if one mode still works, if the thermostat shows a message, or if the problem began when you changed seasonal settings.
We evaluate the reported concern along with the indoor equipment, outdoor unit, airflow, and controls as appropriate. A symptom at one part of the system does not necessarily identify the failed component. Equipment model information helps us tailor the diagnosis.
Troubleshoot both operating modes
- Loss of heating or cooling in ducted and ductless equipment
- Unusual cycling, control messages, and performance changes
- Repair recommendations based on the connected system
Planning your service
If the unit is not operating normally, note the condition and call rather than repeatedly changing settings or resetting it. During the visit, we will explain what was found, which work addresses the fault, and any separate maintenance concerns. When repeated repairs raise replacement questions, we can compare those options with you.
Tell us about your systemExplain when performance changes
Tell us whether the problem happens in heating, cooling, or both, and whether the indoor fan continues to run. Note unusual sounds, repeated shutdowns, or controller messages without opening equipment panels. The pattern matters because a heat pump's heating and cooling functions share parts of the same system.
Check the equipment and its controls together
Thermostat configuration, airflow, indoor components, and the outdoor unit can all be relevant to diagnosis. A symptom in one mode does not identify a failed part by itself. Ask how the proposed repair will be checked and whether both modes need evaluation before the service is considered complete.
Check the mode as well as the symptom
A Petaluma heat pump that cools but does not heat presents a different diagnostic picture from one that does neither. Tell us which mode you selected, what the indoor unit does, and whether a fault message appears. Record the symptom without opening panels or trying to force the system to restart.
For multi-zone equipment in Novato or Rohnert Park, identify whether one room or every connected unit is affected. Controls, airflow, and outdoor-unit operation need to be considered together. Maintenance can address care needs, but an active fault needs a repair diagnosis and a clear explanation of the proposed work.

Your questions, answered.
Tell us the equipment type, the property address, and what you want to improve. We’ll help you choose the right starting point.
Why is my heat pump running longer than my old furnace?
Operating patterns vary by equipment and conditions, so longer operation alone does not establish a fault. If the home is uncomfortable, performance has changed, or the system shows an error, we can evaluate whether it is operating as intended.
Where is this service available?
We are based in Petaluma and serve Sonoma County, the North Bay, Marin County, Napa County, and San Francisco. Call with your address and equipment details to discuss scheduling and the scope of your project.
