Residential Ductless Mini‑Split Installation in Long Beach, CA

At #1 AC Guys, we specialize in residential ductless mini‑split installation for Long Beach homeowners who want efficient comfort, healthy indoor air, and a clean look—without tearing up walls for ductwork. As a 4th‑generation family of engineers with 80+ years of engineering experience, we bring an engineering‑first mindset to every project, from compact studios and ADUs to large multi‑zone homes along the coast.

Is a ductless mini‑split right for your home?

Mini‑splits are an excellent fit when you need targeted comfort and better control. They shine in additions, sunrooms, home offices, garages, and bedrooms that never feel quite right. In Long Beach’s coastal climate, they offer quiet operation, high efficiency, and reliable heating and cooling without duct losses. Each indoor unit controls its own zone, so you only condition the spaces you use—saving energy while improving comfort.

Our engineering‑first installation process

• In‑home assessment: We evaluate your home’s layout, insulation, coastal exposure, and electrical capacity.
• Right‑sizing: We perform precise load calculations to select the correct capacity for each zone.
• System design: Single‑zone or multi‑zone, wall‑mounted or ceiling cassette—we tailor placement for airflow, aesthetics, and serviceability.
• Permits and compliance: We handle local permitting and adhere to California energy standards.
• Installation day: Clean line‑set routing, sealed wall penetrations, vibration‑isolated mounting, and neat electrical work.
• Commissioning: We vacuum, pressure‑test, and verify refrigerant lines; set airflow, modes, and controls for each zone.
• Home walkthrough: We show you how to use filters, remotes, Wi‑Fi controls, and care routines.

Built for Long Beach’s coastal environment

• Corrosion resistance: Hardware and line‑set covers designed to stand up to salt air.
• Protected routing: UV‑resistant line‑set covers and weather‑tight wall penetrations.
• Quiet by design: Outdoor placement tuned to local noise considerations and your property layout.
• Clean condensate control: Properly sloped drains and pumps (when needed) to prevent leaks and odors.

Factory‑trained on leading equipment

Our installers are factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Hier (China). That training informs everything we do—correct sizing, precise refrigerant practices, and commissioning that protects efficiency and reliability.

Healthier air at home

Our mission is healthier air for a healthier life. Ductless systems reduce dust from ducts and provide advanced filtration at the room level. We help you choose filters and maintenance intervals that support cleaner air, especially helpful for bedrooms, nurseries, and home offices.

Transparent pricing and real value

• Clear, itemized proposals tailored to your home and goals.
• Options for single‑zone, multi‑zone, and low‑temperature heat pump performance.
• Guidance on potential energy incentives and seasonal promotions where applicable.

Common Long Beach use cases

• ADUs and garage conversions in Bixby Knolls, Lakewood Village, and Signal Hill.
• Sun‑soaked rooms in Belmont Shore and Naples that need extra cooling.
• Mid‑century homes and bungalows where ducts are impractical.
• Multi‑level homes needing independent temperature control by floor.

What to expect on project day

We arrive on time, protect floors and furnishings, and keep work zones tidy. Outdoor units are leveled and isolated to minimize vibration. We route line sets discreetly, seal penetrations, pressure‑test, evacuate, and commission the system so it performs to spec. Before we leave, you’ll know how to operate every feature and keep filters clean.

We proudly serve Long Beach and all of Los Angeles County, with nearby coverage across Orange County, Ventura County, and Western Riverside County. Whether you’re in Alamitos Heights, Downtown Long Beach, or the East Side, our team is ready to help design the right ductless solution for your home.

Ongoing care

Like any precision system, ductless units perform best with routine maintenance.
