A comfortable room starts with a system that fits the space and the installation—not simply the lowest equipment price. DELLA Home sells several air-treatment and cooling formats. This guide uses one Serena mini split as a concrete starting point for a more informed conversation with an installer.
The Serena configuration in this guide
Our featured listing is the DELLA Serena 12,000 BTU, 22 SEER2 mini-split heat pump in the 115V configuration, SKU 12K1VR-22S-M-I+O. The official page and catalog showed $799.96 on 5 October 2026.
DELLA describes coverage up to 550 sq ft and app control with compatible voice assistants. A stated coverage area is a starting point for assessment, not a guarantee that a system will suit every room of that size.

Put the room before the discount
Measure the area you want to condition and note how it is used. A sunny room, an open connection to another space or a different ceiling height can change what an installer recommends. Share those details before deciding solely from an “up to” coverage figure.
Ask the installer to confirm the exact model, electrical requirements, equipment placement and line-set requirements. A 115V label alone is not evidence that the system can use any existing outlet or that the installation is a do-it-yourself project.
Compare the complete project cost
Keep the equipment price separate from labour and any installation materials. Ask for a written scope so you can compare quotes consistently: what is supplied, what is fitted and what remains your responsibility.
Also check the applicable warranty registration and installation conditions. Our listed price is for the selected equipment; it is not an installed-system quote or a claim about rebates.
Where the welcome offer fits
DELLA’s signup form advertises 5% off a first system. We list it under Ways to Save. Read the actual offer before assuming your selected model qualifies, and compare the final total only after the equipment and installation requirements are clear.

Our take
The right starting point is a well-matched system and a clear installation plan. Once those are settled, compare the exact configuration and available offer without letting a small discount decide a much larger home project.
