What Is a Ductless Mini-Split System?

A ductless mini-split system is a two-part HVAC solution: an outdoor condenser and one or more indoor air handling units. Unlike central air systems that rely on ducts, mini-splits use refrigerant lines to deliver heating and cooling directly to individual rooms or zones. Each indoor unit operates independently, giving you precise control over temperature in each area.

What's included in a mini-split install:

  • System design consultation based on room size, sun exposure, and usage

  • Mounting and positioning of indoor units

When to Replace Your Existing Mini-Split

Ductless systems typically last 12–15 years, depending on usage and maintenance. If your system is underperforming, making noise, or requiring frequent repairs, it may be time to upgrade.

We'll inspect your existing system and recommend whether a targeted repair or full replacement is the better long-term investment.

Signs it's time for replacement:

  • Lack of consistent cooling or heating
  • Rising energy bills
  • Water leakage or refrigerant issues
  • Noisy indoor or outdoor units
  • Outdated or discontinued models
  • Desire for better energy efficiency or more zones

Armstrong vs. LG for Mini-Splits

While Armstrong is our go-to for ducted systems, LG is our preferred brand for ductless mini-split systems due to its high performance, modern design, and excellent warranty coverage.

As an LG-certified contractor, we're trained to install and maintain their complete ductless product line with precision.

Why we recommend LG mini-splits:

  • High SEER2 efficiency ratings
  • Ultra-quiet operation
  • Multi-zone capabilities
  • Smart controls and Wi-Fi-enabled units
  • Compact, modern designs that blend with your space

Ideal Mini-Split Applications in Phoenix Homes

Mini-splits are perfect for areas where ducted systems can't reach or don't make sense. Whether you're finishing a garage, adding an in-law suite, or just want to stop overcooling unused rooms, we can design a system tailored to your needs.

Common installation zones:

  • Detached garages
  • Guest houses or casitas
  • Home offices
  • Converted attics or basements
  • Sunrooms
  • Master suites or second-story bedrooms
  • New additions or renovations

Each zone can be controlled independently, helping you save energy and stay comfortable exactly where you need it.

New Construction Mini-Split Design

If you're building a new custom home or multi-use space, our team will collaborate with your GC or architect to design a ductless system that fits the project layout and HVAC code requirements.

Our design services include:

  • Load calculations by zone
  • Equipment recommendations (single or multi-head)
  • Control integration (smart or wired remotes)
  • Electrical and placement coordination
  • Coordination with framing, drywall, and trim schedules

Maintenance Plans for Mini-Split Systems

Every ductless installation is eligible for a maintenance plan — and given Phoenix's long cooling season, regular service is highly recommended.

We recommend bi-annual maintenance to keep your system operating efficiently and to preserve your warranty coverage.

Our mini-split tune-ups include:

  • Indoor unit coil and filter cleaning
  • Drain line inspection and clearing
  • Fan motor check and lubrication
  • Outdoor condenser cleaning and testing
  • Refrigerant pressure testing
  • Remote or thermostat function verification

  • Mini-split compatible air purification units
  • Humidity control systems
  • UV light sanitation add-ons
  • Zone-specific filtration upgrades

Our Customer Testimonials

5/5

"We recently had an issue with our Trane AC unit, and Shelby from Hometown HVAC did a fantastic job. He quickly diagnosed the problem, replaced the capacitor, and had us back up and running in no time. Shelby has over 30 years of HVAC experience and specializes in residential work, with commercial experience as well. He's professional, knowledgeable, and trustworthy- showed up in a branded truck and uniform, explained everything clearly, and didn't try to upsell us, just focused on the repair. His pricing is very reasonable. He mentioned that he works in North Scottsdale frequently and handles maintenance, repair, and emergency calls. I'd highly recommend Shelby and Hometown HVAC to anyone in the area who needs reliable AC service."

"I have been a GC for over 30 years and when I came to AZ 7 years ago, I met Shelby even before he started HomeTown and have worked with him ever since. My remodel projects are not easy, and Shelby puts in the time on the front end and helps me design. He is very knowledgeable and with his expertise, we can put together an affordable and functional system that I know will work. He has strong communication skills and puts together a clear and detailed estimates. I know that I am only as good as the people around me and that is why I value working with HomeTown HVAC."

Frequently Asked Questions About Mini-Split Installation in Phoenix

Answers to Common Questions from Homeowners, Builders, and GCs

A mini-split is a two-part HVAC system consisting of an outdoor condenser and one or more indoor air handlers. Instead of using ductwork, it delivers cooled or heated air directly into a room via refrigerant lines, providing zoned comfort and excellent energy efficiency.

Mini-splits are ideal for casitas, garages, additions, sunrooms, attics, home offices, and guest rooms. They're also a great solution for second-story rooms that tend to run hotter than the rest of the house.

Depending on the model, multi-zone mini-split systems can support anywhere from 2 to 8 indoor units connected to a single outdoor condenser. We'll help you choose the right configuration for your home's layout and cooling needs.

Absolutely. Mini-splits are a significant upgrade over window or portable ACs. They're more efficient, quieter, better looking, and don't block your windows. Plus, they offer both cooling and heating — making them useful year-round in Phoenix.

Yes. High-quality systems like LG mini-splits are built to handle extreme summer heat in Phoenix, often functioning effectively even when outdoor temperatures reach 110°F or higher.

Very. Because there's no energy loss from ductwork and you can cool specific zones instead of the whole house, mini-splits often reduce utility bills — especially in homes where certain rooms are used more frequently than others.

With proper installation and maintenance, a mini-split system typically lasts 12 to 15 years. Routine tune-ups can extend this lifespan and ensure top performance.

We proudly install and replace LG ductless mini-split systems. LG units are known for their reliability, smart controls, quiet operation, and sleek design. As an authorized LG contractor, we install single-zone and multi-zone systems backed by full warranty coverage.
