If you’re searching for a smart, flexible way to cool (or heat) your home in Chino Hills, ductless AC systems – also known as mini-splits – are a perfect solution!

At Dragonfly Heating & Cooling, we install, repair, and maintain ductless systems for homes of all sizes, from new additions and older houses without ductwork to rooms that just never seem to stay comfortable.

Whether you’re ditching your old central air system or exploring ductless for a single space, we’ll help you find the right setup for your home and keep it running smoothly long after installation.

What Is a Ductless Mini-Split System?

Unlike traditional HVAC systems that rely on ductwork, ductless mini-splits consist of an outdoor unit and one or more indoor air handlers. Each indoor unit operates independently and can be mounted high on a wall or recessed into the ceiling.

Because there’s no ductwork involved, mini-splits can be installed quickly and without major construction, perfect for homes in Chino Hills where architectural constraints or add-on rooms make ducted systems impractical.

Why Chino Hills Homeowners Choose Ductless AC

Mini-splits are growing in popularity throughout the Inland Empire, and for good reason:

  • Energy Efficiency: Ductless systems use inverter-driven compressors and zone-based cooling, helping homeowners cut down on energy waste and reduce monthly utility bills.
  • Room-by-Room Control: Set different temperatures for different rooms based on your comfort needs and usage – no more cooling unused spaces.
  • No Ductwork Required: Ideal for older homes, garages, casitas, and sunrooms where ducts would be too expensive or invasive to install.
  • Dual Heating and Cooling: Most ductless units provide both air conditioning and heat, making them a year-round solution for comfort.

Ductless Mini-Split Installation in Chino Hills

At Dragonfly, we start with a free consultation to understand your home’s layout, your comfort goals, and any specific needs, whether you’re adding a mini-split to a single room or designing a full-home ductless system.

Our installation process is clean, efficient, and designed around your schedule. We handle everything, including:

  • Sizing and system selection
  • Indoor and outdoor unit placement
  • Electrical and refrigerant connections
  • A full system test and homeowner walkthrough

We only install systems from trusted brands known for reliability, performance, and long-term support.

Fast Ductless AC Repair When You Need It Most

If your ductless system isn’t cooling, is leaking water, or isn’t responding to your remote, give Dragonfly a call. We specialize in fast, accurate mini-split repairs across Chino Hills. Our trained technicians can service most makes and models and arrive with fully stocked vans to handle many fixes on the spot.

Common ductless AC issues we repair include:

  • Poor cooling or airflow
  • Sensor or communication errors
  • Refrigerant leaks or low charge
  • Drain line clogs or water leaks
  • Frozen evaporator coils

We’ll never push you toward a new system unless it’s truly the best long-term option. If we can fix it—we will.

Preventative Maintenance Keeps Things Running Right

Like any HVAC system, ductless mini-splits need regular maintenance to perform their best. Dust buildup, clogged filters, and worn components can all reduce efficiency and lead to breakdowns.

Our ductless AC maintenance service includes:

  • Cleaning filters and coils
  • Checking refrigerant levels and system pressures
  • Inspecting electrical connections and safety controls
  • Ensuring drain lines are clear and secure

We recommend scheduling a tune-up twice a year—once before summer and once before winter—to keep your system in peak condition.

Response from the owner:Thank you so much for taking the time to leave us a 5 star review!
Our technician Trevor is very knowledgeable and pleasant. He takes time to let us know if there are any issues we need to be concerned about presently or that could be a problem with our Unit in the future. Thank you Trevor :)

My AC went out on the hottest day of the summer and as we all know that is the busiest day for AC repair. I was worried me and my family would be stuck sweating for at least a week but dragonfly heating and cooling saved me! After calling several companies and being told they didn’t have any open availability Dragonfly was able to send someone out same day and get it fixed and up and running before the end of the day! Reasonable price great customer service. I will never call anyone else again!
Response from the owner:Thank you so much for the 5-star review! We're thrilled to know you had a fantastic experience with us.
Words can not explain how happy I am with Dragonfly, what they did for me and my business was exceptional. I had a new system installed about 2 years ago and it was not performing correctly. The system was not reaching setpoint, Dustin Ramker work is exceptional. He tuned and cleaned my current system perfectly, it is performing better than when it was brand new! Thank you Dragonly, I am so greatful for your Honest & excellent work.
Response from the owner:Thank you so much for taking the time to leave us a 5 star review!
Excellent experience with Dragonfly. Trevor the technician was extremely helpful and knowledgeable on HVAC systems. I really appreciated Trevor’s honesty, clear communication and professionalism. Dragonfly will be my go to for HVAC and plumbing in the future. I highly recommend them.
Response from the owner:Thanks for the positive review Darrell!
