Locally owned and operated and based in Johns Island
On Johns Island, no two homes (or HVAC issues) are exactly alike. At Passion Heating & Air, we skip the cookie-cutter fixes and start every service call with a thorough inspection and diagnostic check. Whether you’re dealing with a small repair or considering a full system replacement, we’ll walk you through your options with honest, no-pressure recommendations tailored to your home, your budget, and the way you live.
When it’s time for a new system, we install trusted brands like Carrier, Trane, and Mitsubishi to deliver dependable, long-term performance. We take the time to properly size your system based on your home’s square footage, insulation, and duct layout – ensuring comfort and efficiency through every Lowcountry season. Each installation includes system testing, duct sealing, thermostat setup, and a full walkthrough so you know exactly what to expect.
For repairs, we prioritize quality parts (OEM whenever possible) and provide a clear breakdown of what’s wrong and how we’ll fix it…no tech jargon, no guesswork.
And if you’re one of our regular maintenance clients, you’ll benefit from precision tune-ups that help prevent breakdowns before they start. We clean coils, test refrigerant levels, inspect electrical components and ductwork, and fine-tune your thermostat to keep your system (and your energy bill) running as smoothly as a summer breeze off the Stono River.

I Wouldn’t Think of Going Anywhere Else.
Rick Wofford
Johns Island, SC
“Passion Heating and Air are absolutely the best. I have used them since I bought my house on Johns Island in 2014. They have been there for me at the spur of the moment and kept me in AC for the last 5 years. One time I tried someone else, and they told me I needed an entire new system ($6000). I was floored. I called John and asked him to come confirm and he said “no, you just need….” I don’t remember what it was, but he fixed it up for a couple hundred. I feel like I really dodged a bullet on that one. Since then, I wouldn’t even think of going anywhere else, because with Passion, I know I get honesty, integrity and quality. I highly recommend them.”

Johns Island HVAC Services – FAQ
What HVAC challenges are unique to Johns Island homes?
Johns Island’s coastal climate brings high humidity, salty air, and seasonal storms, which can wear out HVAC components faster. Homes near the water often face corrosion issues, and many properties have unique layouts—like elevated beach cottages or open-concept ranches—that require careful airflow planning.
How often should I service my HVAC system on Johns Island?
Due to the island’s heat, humidity, and salt exposure, we recommend tune-ups twice a year—once in spring and once in fall. Regular maintenance helps prevent mold buildup, improves energy efficiency, and extends the life of your system in a demanding coastal environment.
Do you offer HVAC systems designed for coastal climates?
Yes! We install corrosion-resistant units designed specifically for humid, salty air—ideal for Johns Island conditions. Brands like Trane and Mitsubishi have coastal-grade components built to withstand moisture and sea air.
Can you install HVAC systems in elevated or pier-style homes?
Absolutely. Many Johns Island homes are built on pilings or have unique architectural features. Our team has experience customizing ductwork and equipment placement to match your home’s layout without compromising performance or aesthetics.
Are energy-efficient HVAC options available for Johns Island homeowners?
A: Definitely. We offer high-SEER systems, smart thermostats, and ductless mini-splits that reduce your energy bills and handle our local climate with ease. We’ll help you qualify for any South Carolina energy rebates too.
