Residential Heat Pump Installation in Pasadena

Engineering-first heat pump design for Pasadena homes

A heat pump is only as good as its design. We begin with a detailed assessment: Manual J load calculations, Manual S equipment selection, and Manual D duct design or verification. That means correct sizing, proper airflow, and balanced distribution—no short cycling, no hot-and-cold rooms. We optimize refrigerant line lengths, charge, and evacuation procedures to manufacturer standards and document commissioning results for long-term reliability.

Our mission is healthy air for healthy living. Alongside efficient heating and cooling, we integrate advanced filtration, humidity control, and fresh-air strategies tailored to Pasadena’s microclimates. The result is cleaner indoor air, stable comfort, and lower energy use all year.

What we install

• Ducted heat pump systems for whole-home comfort and quiet operation
• Ductless mini-splits and multi-zone solutions for additions, ADUs, and room-by-room control
• High-performance inverter systems for superior efficiency and low noise
• Premium filtration, ventilation add-ons, and smart thermostats for healthier air

We are factory-trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Hier (China). Our team applies that training to deliver precise installations that follow each manufacturer’s best practices.

Healthy air focus

Comfort is more than temperature. We can pair your new heat pump with right-sized filtration, fresh-air ventilation, and humidity management to support better sleep, allergy relief, and overall wellbeing. Ask about enhanced MERV filtration and smart controls for precise, automatic comfort.

Permits, codes, and incentives

We manage local permits and meet California Title 24 energy requirements for every Pasadena project. Many homeowners may qualify for utility rebates or tax incentives for heat pumps; we guide you through eligibility and documentation to help you capture available savings.

Ducted or ductless—what’s best for your home?

Ducted systems work well for whole-home comfort and can reuse or improve existing ducts. Ductless mini-splits shine in homes without ducts, room additions, home offices, or where zoned control is a priority. Multi-zone systems let you condition only the rooms you use—reducing energy waste and increasing comfort.
