The Senville Story

One Brand, Every Climate

From the compact 9,000 BTU LETO to the 36,000 BTU multi-zone condenser, Senville covers a single room or a whole home with the same inverter technology. Each system heats in winter and cools in summer, running quieter and leaner than the window units it replaces.

Pre-charged line sets and plain-English guides mean a handy homeowner can install many models in a weekend, and our specialists are a call away when you want a pro.

Installed the 12,000 BTU LETO myself in a weekend. Bedroom stays cool in summer and warm in winter. Power bill dropped noticeably.

Marcus T. · Garage Conversion
★★★★★

The multi-zone unit handles three rooms from one condenser. Quiet, efficient, and the heat pump keeps up even on cold nights.

Dana R. · Whole-Home Retrofit
★★★★☆

Great value against the name brands. Citadel shipped fast and the spec sheets made sizing simple. Would buy again.

Common Questions

Senville FAQ

Sizing, install, and efficiency are the three things buyers ask about most. Here are clear answers so you can order the right system with confidence.

Talk to an HVAC Specialist
What size BTU do I need for my room?+As a rule of thumb: 9,000 BTU covers up to about 400 sq ft, 12,000 BTU up to 550, 18,000 BTU up to 1,000, and 24,000 BTU up to 1,500. Ceiling height, insulation, and sun exposure shift those numbers, so when in doubt size up one step or ask our team for a quick load check.
Can I install a Senville mini-split myself?+The LETO and AURA series ship with pre-charged line sets and clear guides, so a handy homeowner can mount the heads and run the lines. Final electrical hookup should be done by a licensed electrician, and we can connect you with a vetted installer if you would rather hand off the whole job.
Do these units both heat and cool?+Yes. Every system on this page is a true heat pump: it cools in summer and heats in winter from the same unit, with inverter compressors that hold temperature without the on-off cycling of older systems.
What is a single-zone vs multi-zone system?+Single-zone pairs one indoor head with one outdoor condenser, ideal for a bedroom, office, garage, or addition. Multi-zone runs up to five indoor heads from a single condenser, each with independent control, for whole-home comfort without ductwork.
How efficient are Senville heat pumps?+SEER ratings run up to 22 thanks to inverter compressor technology. Against window units or an aging central system, most owners see a noticeable drop in their energy bill, especially when heating through winter.
How long does shipping take?+Most systems leave the warehouse within 1 to 2 business days and arrive by freight within about a week, fully insured, anywhere in the contiguous US. You will get tracking the moment it ships.
What warranty comes with each system?+Senville backs the compressor for up to 7 years and parts for 5, with US-based support and stocked replacements. Keep your install documentation; registration takes a few minutes and locks in the full term.
