Residential Ductless Mini‑Split Installation in Fontana

Ductless mini‑splits give Fontana homes efficient comfort without the mess of ductwork. Whether you’re finishing a garage conversion, adding an ADU, or replacing window units, #1 AC Guys designs a solution that fits your architecture and your lifestyle. Our mission is healthy air for a healthy life, so every recommendation balances comfort, air quality, energy savings, and long‑term reliability.

Why ductless fits Fontana living

Mini‑split heat pumps deliver targeted cooling and heating where you need it, when you need it. They’re ideal for hot Inland summers and shoulder‑season heating—without the energy loss of ducts.

• High efficiency (SEER2/HSPF2) that cuts utility bills versus window or portable units.
• No duct losses—more of your energy becomes usable comfort.
• Room‑by‑room zoning for personalized temperatures and smarter energy use.
• Advanced filtration and humidity control for cleaner, healthier indoor air.
• Whisper‑quiet operation—great for bedrooms, nurseries, and home offices.
• Flexible installation: walls, ceilings, or low‑wall consoles for tight spaces and design goals.

Our engineering‑first installation process

With 80+ years in engineering across four generations, we approach every home like a unique system, not a one‑size‑fits‑all job.

• Home evaluation and load calculations to right‑size capacity for each zone.
• Design options: single‑zone, multi‑zone, and head placement for coverage and aesthetics.
• Permit guidance and code‑compliant plans.
• Precision placement of indoor units and outdoor inverter for airflow, service access, and noise control.
• Clean line‑set routing, insulation, and condensate management to protect walls and finishes.
• Vacuum, pressure testing, and proper charging to manufacturer specifications.
• Electrical integration, safety checks, and control setup (wired/wireless, app‑ready where applicable).
• Performance commissioning: verify airflow, superheat/subcooling, and thermostat calibration.

We specialize in complex residential projects—older homes, sun‑baked rooms, vaulted ceilings, long line runs, and multi‑story layouts—delivering neat installs that blend with your space.

Equipment options we work with

Our team is factory‑trained at Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). That training informs how we design, mount, connect, and commission each system to meet manufacturer guidelines and achieve peak performance.

• Single‑zone mini‑splits for target rooms and additions.
• Multi‑zone systems for whole‑home comfort with independent controls.
• Wall‑mounted, ceiling cassette, and floor console indoor units for any interior.
• Cold‑weather heat pump options for reliable winter heating on chilly nights.
• Enhanced filtration and allergen‑reduction features for healthier air.

Transparent pricing and real value

We provide clear, line‑item proposals with choices. You’ll see equipment, labor, and accessories so you can compare efficiencies, comfort features, and lifetime cost of ownership. No surprises—just engineered solutions that fit your budget and goals.

Respect for your home

• Protective floor coverings, shoe covers, and careful routing to minimize wall penetrations.
• Line‑hide and color‑matched solutions where possible for a clean exterior look.
• Thorough cleanup and homeowner walkthrough before we leave.
