Residential Ductless Mini-Split Installation in Pasadena

Ductless mini-splits deliver efficient, room-by-room heating and cooling without the cost and disruption of new ductwork—ideal for Pasadena homes, ADUs, garages, studios, and upstairs suites. With inverter technology, these systems maintain steady, precise temperatures while using less energy and operating whisper-quiet.

Tailored for Pasadena Homes

From Bungalow Heaven and Madison Heights to Linda Vista and San Rafael Hills, Pasadena homes come in many shapes, ages, and building envelopes. We design residential ductless mini-split installations that respect your home’s character, meet local codes, and fit tight spaces—all while maximizing comfort and air quality.

• Perfect for additions, home offices, and rooms that are hard to heat or cool
• Zoned comfort: set different temperatures for different rooms
• High efficiency and potential utility savings
• Minimal construction—no bulky ducts required
• Quiet operation for bedrooms, nurseries, and studios

Our Residential Installation Process

• In-home consultation and heat-load calculations for right-sized equipment
• System design and location planning for indoor and outdoor units
• Product selection from leading manufacturers we are factory-trained on
• Neat line-set routing, electrical, and condensate management
• City of Pasadena permit handling and Title 24 compliance
• Factory-standard commissioning, testing, and homeowner orientation

We prioritize healthy indoor air as our core mission. Each mini-split includes multi-stage filtration; we can also discuss advanced filtration and compatible fresh-air options to help reduce particulates and support better indoor air quality.

Factory Training That Matters

Performance and longevity depend on proper design and commissioning. Our engineers are factory-trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That training informs our sizing, refrigerant practices, control setup, and diagnostics—so your system runs as the manufacturer intended from day one.

Ideal Applications in Pasadena

Older homes without ducts, detached garages converted to living space, attic bedrooms, sunrooms, and home studios often benefit most from ductless mini-splits. Multi-zone systems let you condition several rooms independently, while single-zone systems are cost-effective for a single problem area.

What to Expect on Install Day

We protect floors and furnishings, confirm equipment placement, and route line sets with a focus on aesthetics and serviceability. We set proper clearances for outdoor units, establish secure mounts, and charge and test to factory specifications. After commissioning, we walk you through controls, cleaning, and maintenance best practices.
Most residential installs are completed in one to two days, depending on scope and access.
