This guide shows how to choose with Della in mind when comparing a mini split with central AC for a US home. The deciding factor is often existing ductwork, since Della lists central systems for ducted homes and mini splits as ductless options. Readers also get sizing, shipping, warranty and return details to review before ordering.
Key Takeaways
- Mini splits offer single or multi zone setups, with 2 to 6 zones listed.
- Central AC is listed as professional installation only and sized by home area.
- Extended warranty requires registration within 100 days, and the warranty does not cover technician labor.
- Returns allow 30 days, but customers pay return shipping and exchanges are not offered.
Mini Split or Central AC? How to Choose With Della in Mind starts with a simple question about the home itself. The choice often depends on whether a home already has ductwork. Homes with existing ducts and homes without them can point toward different system types.
Della is a US brand of home comfort products, including mini splits, central AC and pool heat pumps. This guide is written for US homeowners, including first time buyers, who are comparing a room by room system with a whole home system.
The sections ahead cover brand background, how to choose, current offers, product highlights, fit and timing, and purchase tips. Each part is meant to help readers review the options using clear, official details.

Fit and Timing: Sizing, Space and When to Plan
Match the System to the Space
Della organizes its Central AC by home type and square footage. Each mini split lists its own coverage area. Readers can compare their room or home size to the listed range before choosing a model.
- Use Della’s mini split sizing calculator on the official site.
- Try the product finder quiz for guidance on matching a system to a space.
- Review the listed square footage on each product page.
Plan Around Shipping and Registration
Della lists a processing time of 1 business day, or 2 to 4 business days in peak seasons. Transit is then listed at 1 to 3 business days. Timing may vary, so readers can check the shipping policy on dellahome.com when planning.
Warranty registration is also worth adding to the plan. Registering within 100 days of purchase is required for Della’s extended warranty coverage.
Purchase Tips Before Checkout
A few quick checks before ordering can help shoppers avoid surprises and match a Della system to their home.
- Confirm whether the home has ductwork and whether professional installation is planned. Della offers a “Find Partner HVAC Installer” page on its official site.
- Check the voltage listed on the product page and follow the official manual. For example, the DELLA Motto Series 12,000 BTU 20 SEER2 Mini Split Heat Pump AC lists 115V in its product name.
- Register the unit within 100 days of purchase to qualify for extended warranty coverage. Della’s warranty does not cover technician labor.
- Review the return policy. Della lists a 30 day money back guarantee, and products must be returned in original operating condition with accessories and packaging. The customer pays return shipping, and exchanges are not offered.
- Confirm the delivery address qualifies. Della ships to street addresses in the lower 48 states and does not ship to P.O. boxes.
- Use phone or live chat support for product questions before ordering.
Summary
The blog compared Della’s mini splits and central AC systems, starting with whether a home already has ductwork. It covered five models, including the 24,000 BTU central unit listed from $3,499.96 and the Motto Series 12,000 BTU mini split listed at $769.96. It also listed current offers: free ground shipping in the lower 48 states, 5% off a first system for new email sign ups, and a 10% military and first responder discount through GovX. Terms may change, so these should be confirmed on the official site.
Two features stood out. Della sizes its central AC by home area, with the 24,000 BTU model listed for 800 to 1,000 sq ft and the 34,000 BTU model for 1,001 to 1,500 sq ft. On the mini split side, the Motto Series is a single zone system listed for up to 550 sq ft, and the Optima Series dual zone model is listed for up to 1,100 sq ft with room by room control. Della also lists lifetime parts coverage on its mini splits when they are registered within 100 days.
Two checks matter most before ordering. First, confirm whether the home has usable ductwork, because Della’s central AC requires it and is listed as professional installation only. Second, register the unit within 100 days to qualify for extended warranty coverage, and keep in mind that the warranty does not cover technician labor. The 30 day return window also comes with return shipping paid by the customer, and exchanges are not offered.
