HVAC repairCompare equipment with the rooms, distribution, placement, and supporting work included. Discuss both heating and cooling goals before settling on a system.
HVAC installationPlan equipment care around the system and its instructions. Ask about filter care, thermostat use, and issues that need separate repair rather than routine maintenance.
HVAC maintenancePlease confirm who can provide access and authorize work. If the unit is reached by steps or through a separate entrance, include that information so service can be planned around the site.
We explain the proposed scope before work begins. If you are planning an upgrade, ask about FTL Finance options, applicable equipment warranties, and what the installation includes. Availability and terms depend on the project and provider.
For recurring care, our Diamond Thermostat membership plans provide another way to discuss heating and cooling maintenance with the team.
Yes. Tell us which rooms are affected and whether the unit itself is producing warm air. We can assess operation and discuss the limits of the current layout before suggesting changes.
Call (707) 762-7260 or use our contact form with the address, equipment type, and symptoms. Our Petaluma team will discuss the scope and confirm scheduling. A request does not automatically reserve an appointment.
