A multi-zone system needs a complete scope.
Each ductless indoor unit has its own filter and accessible components, even when several connect to one outdoor unit. Tell us how many heads are installed and where they are located so the maintenance plan covers the areas you want serviced.
We discuss airflow, drainage, controls, and changes in heating or cooling performance. A bedroom unit used nightly may have a different usage pattern from a rarely used guest room. That information helps make the visit specific to the household rather than just a count of equipment.
Give each indoor zone its own attention
- Care for indoor units and accessible outdoor equipment
- Filter and operating concerns reviewed across zones
- Owner maintenance explained using the system instructions
Planning your service
Provide clear access below wall-mounted units and around the outdoor equipment. We will explain which routine filter tasks you can perform under the manufacturer’s instructions and which tasks call for professional service. If a zone is already leaking or has stopped working, tell us when scheduling so diagnosis is included in the discussion.
Tell us about your systemCount the indoor heads in the service scope
A multi-zone home may have equipment in bedrooms, shared living spaces, and an addition, all connected to one outdoor unit. Provide the number and location of indoor units when arranging maintenance. Discuss access, filter care, and any room-specific issue so the work covers the zones you actually want serviced.
Plan care around use and accessibility
Some zones operate daily while others are used occasionally, and high-mounted units may need extra access planning. Ask which owner cleaning tasks the manufacturer allows and which parts need professional attention. If an indoor unit leaks, stops responding, or displays a fault, describe that separately from the routine maintenance request.
Include every indoor zone in the care plan
A Petaluma household may use one mini-split zone daily and another only for guests. Both should be included when discussing maintenance, filter care, and access. Tell us about musty odors, water, unusual noise, or a change in airflow rather than assuming each unit simply needs the same cleaning.
The outdoor unit also needs accessible space around it, whether it sits beside steps, a garden, or a deck. We can review routine care based on the installed models and explain concerns requiring repair separately. Keep the controller instructions and equipment details together so whoever uses the room knows the normal settings.

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.
Can I wash every filter in a mini split?
Not every filter or accessory is washable. Follow the instructions for the specific component, and ask if you are unsure. We can help identify the installed filters and explain the appropriate care or replacement approach.
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.
