Are ductless mini-splits more expensive to install than central air?
For a home with existing ductwork, central air is typically cheaper. For a home without ducts, ductless is significantly cheaper because you avoid the cost of installing ductwork ($5,000-$10,000+). A single-zone ductless unit for one room starts at $3,500-$6,000 — far less than adding ducts and a central system. The right choice depends entirely on whether your home already has usable ductwork.
How many indoor ductless units do I need for my whole house?
It depends on your floor plan. A typical 3-bedroom 2-bath Sacramento home would use 4-5 indoor units: one each for the living room/kitchen open area, master bedroom, and secondary bedrooms. Open floor plans may need fewer units; compartmentalized older homes may need more. A single large ceiling cassette can sometimes cover an entire open living area. Fresh Air assesses airflow and room layout during the estimate to recommend the right number and placement of indoor units.
Do I need to clean ductless mini-split filters?
Yes — ductless indoor units have washable filters that should be cleaned every 2-4 weeks during heavy-use seasons. This is a simple task: open the front panel, remove the filters, rinse with water, let dry, and reinsert. It takes 2-3 minutes per unit. Neglecting filter cleaning reduces efficiency and can lead to mold or odor issues. This is the only regular homeowner maintenance ductless systems require beyond annual professional service.
Can a ductless system heat as well as cool?
Yes — most ductless mini-splits sold today are heat pumps that provide both heating and cooling. In Sacramento's mild winters, a ductless heat pump can handle most or all of your heating needs efficiently. Cold-climate models provide full heating capacity down to 5°F or below. If you are replacing both heating and cooling, a ductless heat pump is an all-in-one solution.
Will a ductless system increase my home's resale value?
Ductless mini-splits are increasingly seen as a premium feature, especially in California where energy efficiency is highly valued. They demonstrate that the home has modern, efficient HVAC — a selling point for energy-conscious buyers. For homes that previously lacked air conditioning entirely (common in older Sacramento neighborhoods), adding ductless AC is a significant value-add that expands the buyer pool.
How long do ductless mini-splits last?
A well-maintained ductless mini-split typically lasts 12-15 years, similar to a central air conditioner. Because ductless systems run year-round (heating and cooling), they accumulate more operating hours than a furnace that only runs in winter. Regular professional maintenance and diligent filter cleaning by the homeowner can extend lifespan toward the upper end of that range. Manufacturer warranties on ductless equipment typically cover the compressor for 10-12 years and parts for 5-10 years.
