Stay Cool With a System That Actually Works

If your air conditioner is struggling – or worse, has completely shut down – it might be time to consider a new AC installation. In Chino Hills, where summers regularly hit the 90s and heat lingers into the evening, a working air conditioner is a must. At Dragonfly Heating & Cooling, we make the process of replacing or installing an air conditioner simple, stress-free, and built around your needs.

Whether you live in a newer development or an older home, we’ll help you choose the best cooling system for your space, your budget, and your lifestyle.

Do You Really Need a New AC?

If you’re not sure whether it’s time to replace your unit, here are some signs homeowners in Chino Hills often experience before making the switch:

  • Frequent repairs: If you’ve called for service more than once in the last year, you may be sinking money into a system that won’t last.
  • Inconsistent temperatures: Some rooms are cool, others are stuffy. That’s often a sign your AC isn’t distributing air properly or isn’t sized right for your home.
  • Rising energy bills: Older systems lose efficiency over time, causing your utility bills to climb with no noticeable improvement in comfort.
  • Loud or strange noises: Grinding, squealing, or rattling are usually signs of failing internal parts—not a quick fix.
  • Age of the unit: If your AC is 10–15 years old, chances are it’s using more energy and delivering less comfort than today’s high-efficiency systems.

What’s Involved in an AC Installation?

Installing a new air conditioner isn’t just about swapping units. Done right, it means assessing your home’s size, insulation, ductwork, and energy use to find a system that’s properly matched.

When you work with Dragonfly, here’s what the process looks like:

  1. Home assessment: We evaluate your layout, existing system, and cooling goals.
  2. System recommendation: We walk you through the options that make the most sense, whether that’s a traditional central AC or a ductless mini-split.
  3. Installation day: Our licensed technicians remove your old system and install the new one with care and precision – no shortcuts.
  4. Post-install walkthrough: We’ll test the new system, explain how to use it, and make sure you’re 100% satisfied before we leave.

We also offer financing options, so you don’t have to delay a more efficient, reliable system because of the upfront cost.

Response from the owner:Thank you so much for your 5 Star review Jonathan!
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!
