The Ultimate Guide to Ductless Mini-Split Installation

When it comes to efficient, customizable home comfort, ductless mini-split systems have earned their spot as the go-to solution for Salt Lake City and Northern Utah homeowners. At Ogden HVAC, we’ve installed dozens of these units—so whether you’re tackling a hot attic, splitting zones between your living room and bedroom, or adding A/C to a new addition, here’s everything you need to know.

What Is a Ductless Mini-Split?
A ductless mini-split consists of two primary components:

1. Indoor Air Handler(s): Mounted high on a wall (or recessed in a ceiling), these units quietly blow conditioned air directly into your room.
2. Outdoor Condensing Unit: The “engine” that compresses refrigerant and expels heat outdoors.

Because there’s no ductwork, you bypass the inefficiencies and installation costs of traditional central HVAC. Each indoor unit connects via a small refrigerant line to the outdoor unit—hence “mini-split.”

5 Key Benefits

1. Zone Control
   Set different temperatures for each room. Turn the office off when you’re not working, and keep the nursery cozy at 72°F.
2. Energy Efficiency
   No duct losses (which can account for 20–30% of a system’s energy). Modern SEER ratings of 20+ slash utility bills.
3. Whisper-Quiet Operation
   Indoor handlers run at noise levels as low as 19 dB—so quiet, you’ll forget they’re on (until you feel that perfect breeze).
4. Small Footprint
   Indoor units are slim and unobtrusive; the outdoor condenser is about the size of a small suitcase.
5. Heating & Cooling
   Most mini-splits are heat pumps—so you get efficient heating in winter and cooling in summer, all in one package.

The Installation Process

1. Site Survey & Consultation
   We evaluate your space, desired zones, and structural considerations (wall strength, line‐set routing, electrical capacity).
2. System Design & Equipment Selection
   Choose the number of indoor units and the appropriate capacity (BTU ratings) per zone. We recommend slightly oversizing to account for Utah’s heat spikes.
3. Mounting the Indoor Units
   Create a 2–3″ hole through the wall for the refrigerant lines, condensate drain, and power. Install the mounting bracket and secure the air handler.
4. Placing the Outdoor Unit
   Position on a stable pad, away from heavy foot traffic, and clear of debris or deep snow. Connect refrigerant lines, electrical wiring, and condensate piping.
5. Vacuum, Charge & Test
   Evacuate the refrigerant lines to remove air and moisture, charge to spec, and run through test cycles. We verify temperatures, airflow, and check for leaks.
6. App & Remote Setup
   Most systems include a handheld remote—and many now offer Wi-Fi modules. We’ll connect your units to your home network for smartphone control and scheduling.
7. Client Walk-Through
   We show you how to adjust temperature, set weekly timers, and switch between heating/cooling modes—plus maintenance tips like filter cleaning.

What to Expect on Cost

• Single-Zone Systems: Typically range from $3,500–$5,500 all-in (equipment + labor).
• Multi-Zone Systems (2–4 heads): $6,500–$12,000 depending on head count and complexity.
• Factors Influencing Price:
  • Number of indoor units (zones)
  • Distance between indoor and outdoor units
  • Electrical upgrades (dedicated breakers, conduit)
  • Structural work (hard-to-reach installs or special mounting)

Even at premium upfront cost, many homeowners recoup their investment through energy savings and eliminated duct maintenance.

Maintenance & Longevity

• Clean Filters Monthly: Slide-out filters rinse under a faucet—let them dry completely before reinstalling.
• Annual Check-Up: We inspect refrigerant levels, test safety controls, and clean the outdoor coil.
• Protect the Outdoor Unit: Keep it clear of leaves, snow, and debris. A simple cover in winter prevents damage.
• Professional Tune-Ups: A yearly visit by Ogden HVAC keeps warranties valid and efficiency optimized.

With proper care, your mini-split can run for 15+ years.

Is a Mini-Split Right for You?

• Additions & Conversions: Perfect for garage-turn-game-room or basement-recap projects.
• Room-by-Room Comfort: Ideal when central air isn’t feasible—or when you want precise control.
• Eco-Friendly Upgrades: High-efficiency models qualify for local rebates and tax incentives.

If you’ve got a tricky spot, uneven home, or simply crave zoned comfort, a ductless mini-split is a smart choice.
