The Della Optima TP mini-split lists for about $921 — but a local professional installation in Austin ran $3,600, underlining how labour often dwarfs hardware on ductless systems. The 12,000 BTU model (048-TP-12K1V-23S-IN) delivers 12,400 BTU of heating, draws up to 960 watts from a standard 115‑volt circuit and is rated for roughly 550 sq ft. Della paid for a professional install for the review; the crew spent about five hours fitting the system, illustrating the gap buyers should budget for when comparing hardware prices.
What the Optima TP promises - Model tested: 048-TP-12K1V-23S-IN. - Capacity: 12,000 BTU cooling / 12,400 BTU heating. - Power: up to 960 watts; designed for a 115‑volt circuit. - Coverage: rated to cover roughly 550 sq ft. - Package: indoor air handler, outdoor compressor, conduit kit (refrigerant lines, drain line, wiring); requires a hole between interior and exterior for the conduit. Market context - Mini-splits are growing in popularity because they’re smaller, quieter and easier to install than full HVAC systems. One study cited in the review pegs ductless systems’ domestic market share at more than 40%, with higher uptake in parts of Asia and Europe. Price versus total cost - Hardware price in review: about $921 with an Amazon coupon, placing the Optima TP in the lower tier for mini-splits. - Installation can dominate the final bill: Della covered the professional install for the review; an independent Austin quote for removal, mounting, refrigerant connections and commissioning was $3,600. - DIY is possible for some buyers (especially on 115‑volt models), but many homeowners need or prefer pros because of wiring, refrigerant handling and local code requirements. Installation: a reality check - The installer crew removed the previous unit and fitted the Della Optima in about five hours. - The team had to drill a new conduit hole because the prior opening was in a different position. - The indoor unit mounts to a supplied metal bracket; a template in the box shows bracket placement and where to cut the conduit hole. - A past unit at the reviewer’s house failed within two years and professionals later attributed that to installation mistakes, illustrating how a poor install can shorten a mini-split’s life. Smart features and day-to-day use - The review included a screenshot of Della’s Della+ mobile app. The company offers a companion app for remote control and settings. - Smart features referenced in the review include remote access and scheduling via the Della+ app, which many buyers value for convenience and basic automation.Related Articles

The Optima TP’s roughly $921 hardware price is attractive, but buyers should factor in professional installation — the Austin quote used here was $3,600 and installers spent about five hours fitting the system. For many shoppers the total installed cost and installer quality matter as much as the unit price.
