Residential Heat Pump Installation in Fullerton, CA

Why Heat Pumps Are Ideal for Fullerton

Fullerton’s warm summers and mild winters are perfect for modern heat pumps. Today’s variable‑speed inverter systems deliver stable temperatures, quiet operation, and impressive efficiency—often cutting heating costs while providing premium cooling. Whether you need a single‑zone mini‑split for an ADU or a whole‑home ducted system, we engineer a solution that fits your home’s layout, electrical service, and comfort goals.

What We Install

• Ducted heat pumps for whole‑home comfort with existing or new ductwork
• Ductless mini‑splits for additions, home offices, and rooms that never feel right
• Multi‑zone systems to balance temperatures across multiple areas
• Cold‑climate and high‑SEER/SEER2 models for maximum efficiency
• Smart thermostat integrations and advanced filtration for healthier air

All equipment is selected and configured based on Manual J/S/D and field‑verified commissioning, not rule‑of‑thumb guesses.

Our Engineered Process

• Discovery and goals: comfort issues, noise, indoor air quality, and energy targets
• Manual J load calculation: room‑by‑room sizing to avoid hot/cold spots
• Manual S equipment selection: right capacity and modulation range
• Manual D duct design: quiet airflow, low static pressure, and proper returns
• Electrical review: breakers, wiring, and disconnects for safe operation
• Permits and Title 24 compliance: plans, forms, and local inspections
• HERS testing and commissioning: refrigerant charge, airflow, and controls verification
• Owner handoff: system walk‑through, filter guidance, and maintenance plan

Healthier Indoor Air Is Our Mission

Healthy air is central to our work. We can incorporate high‑MERV filtration, dedicated outdoor air strategies, humidity control, and duct sealing to reduce particulates and improve ventilation. The result is cleaner, quieter comfort that supports better sleep, fewer allergens, and a healthier home environment.

Rebates, Incentives, and Electrification

We guide you through available incentives such as TECH Clean California and local utility rebates in Orange County.
