Overview
Zoned, ductless comfort for additions, casitas, garages, and rooms your central system just can't reach.
Not every space has ductwork — and not every space needs it. Ductless mini-splits deliver quiet, efficient heating and cooling to a single room, an addition, a workshop or a casita without cutting into ceilings or losing 25% of your capacity to duct leakage. Installations start at $2,500 for a standard single-zone system.
A mini-split is two pieces: a slim outdoor condenser and one or more indoor air handlers connected by a small refrigerant line-set through a 3-inch wall penetration. No ducts, no chases, no soffits.
Because there's no duct loss, mini-splits regularly deliver 20–30% better real-world efficiency than a comparable ducted system in the same square footage.
Every indoor head is its own zone with its own remote or app control. Cool the casita without cooling the empty guest bedroom.

Why It Matters
What you actually get out of it.
No Ductwork Required
Perfect for homes without existing ducts, and for additions where extending the main system isn't practical.
Zoned Comfort
Every head is its own zone. Heat the office, cool the bedroom, leave the guest room off.
High Efficiency
SEER2 ratings of 20+ are common. Inverter-driven compressors sip electricity compared to single-stage central AC.
Quiet Operation
Indoor heads run at 19–35 dB — quieter than a whisper. Outdoor units are dramatically quieter than a traditional condenser.
Cooling AND Heating
Heat-pump mini-splits deliver efficient heating down to well below Valley winter lows.
Frequently Asked
Ductless Mini-Splits
questions.
What's included in the $2,500 starting price?
+
A standard single-zone install: one outdoor condenser, one indoor wall-mount head up to 12,000 BTU, up to 15 feet of line-set, wall penetration, electrical connection to an existing accessible circuit, startup and commissioning.
What would push the price above $2,500?
+
Longer line-sets, higher-capacity heads, ceiling-cassette or floor-mount indoor units, multi-zone systems, and any new electrical circuit or sub-panel work.
Do mini-splits heat as well as cool?
+
Yes — all the systems we install are heat pumps and deliver efficient heating down through Valley winters.
How long do mini-splits last?
+
A well-installed, well-maintained mini-split runs 15–20 years — comparable to or better than a traditional central system.
Do they qualify for utility rebates?
+
Often, yes. APS and SRP periodically offer rebates on high-efficiency ductless equipment. We'll flag any current programs during the quote.
