Some things should be simple. When your air conditioning quits on the hottest day in July or your water utility sends a backflow test notice, you shouldn’t have to wonder who to call — or worry about getting an honest answer when you do. That’s where we come in. Triangle Backflow, Heating & Air is a locally owned and owner-operated company providing HVAC and backflow services to homeowners across Chapel Hill, Carrboro, Pittsboro, Apex, Durham, Raleigh, and the surrounding Triangle communities. We’ve been doing this since 2021, and every job still gets the same attention it did on day one.
We’re not a franchise. There’s no call center, no corporate script, and no revolving door of unfamiliar faces showing up at your house. When you call us, you’re talking to the people who actually do the work — state-licensed technicians who live right here in the Triangle and care about getting it right.



If you’ve received a notice from OWASA or your local water authority saying your backflow prevention device needs to be tested, don’t stress about it. It’s a routine requirement designed to keep your drinking water safe, and it’s one of the things we handle every single day. A backflow preventer stops contaminated water from flowing backward into the clean water supply — and municipalities across Wake County, Orange County, and Chatham County require regular testing to make sure those devices are doing their job.
Here’s what that looks like with us: we schedule a time that works for you, our certified technician runs the test (it usually takes about 15 to 20 minutes), and we file the results directly with your water authority so you don’t have to chase paperwork. If your device needs repair or replacement, we’ll explain exactly what’s going on and what it’ll cost before we touch anything. No surprises. Backflow testing doesn’t have to be complicated, and with us, it isn’t.
North Carolina weather doesn’t really do “mild.” Summers in the Triangle are hot, sticky, and long. Winters bring cold snaps that seem to show up out of nowhere. And then there’s spring, when the pollen is so thick your outdoor unit looks like it’s been dusted in yellow chalk. Your HVAC system deals with all of it, and when something goes wrong, you notice fast.
Triangle Backflow, Heating & Air provides full-service heating and air conditioning repair, maintenance, and installation for homes throughout the Chapel Hill area and greater Triangle region. Whether it’s an AC that’s blowing warm, a furnace that won’t kick on, uneven temperatures room to room, or a system that’s running nonstop and driving your Duke Energy bill through the roof — we diagnose the real problem and fix it. Our technicians carry common parts on every service call, which means a lot of repairs get done in a single visit without a callback.
Older homes near Franklin Street and Carrboro have their own quirks — original ductwork, tight crawl spaces, equipment that’s been patched together over the decades. Newer construction in places like Briar Chapel and Meadowmont comes with its own set of considerations around modern high-efficiency systems. We’ve worked on all of it, and that hands-on local experience makes a real difference when it comes to getting your diagnosis right the first time.
There are a lot of HVAC companies in the Triangle. So why do people keep calling us? It comes down to a few things that are hard to fake.
We’re owner-operated. That means the person answering your call has a personal stake in making sure you’re happy — not a quarterly bonus tied to upselling you a new system. We give you a clear, honest quote before any work starts. If a $12 capacitor fixes the problem, we’re not going to pitch you a $6,000 replacement. That kind of straightforward approach is how we’ve earned the trust of homeowners from Southern Village to Pittsboro and everywhere in between.
Our technicians are state-licensed and certified for both HVAC and backflow work, which means one company handles what would normally require two separate service calls from two different contractors. That saves you time, and it saves you money. We show up when we say we’re going to, we explain what we find in plain language, and we clean up before we leave. It sounds basic, but you’d be surprised how rare that combination actually is.
Triangle Backflow, Heating & Air proudly serves homeowners across a wide stretch of central North Carolina. Our core service area includes Chapel Hill, Carrboro, Hillsborough, and surrounding Orange County communities. We’re also throughout Wake County — covering Raleigh, Apex, Cary, Holly Springs, and Fuquay-Varina — and across Chatham County, including Pittsboro, Siler City, and the Governors Club area. If you’re in the Triangle and you need backflow testing or HVAC service from a local company that treats you like a neighbor, we’re your team.

A backflow prevention device is used to protect potable water supplies from contamination or pollution due to backflow. In water distribution systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower, or other fixture.
Posted on Katrina Garrison UPDATE: Once again, Mohammed came to the rescue. I called him with an emergency (backflow device froze/cracked) and he was able to order the part and install the new device within 24 hours of my initial call. OUTSTANDING SERVICE!! I highly recommend Triangle Backflow to anyone who needs this service. I was very pleased with Triangle Backflow and appreciate the extra mile that Mohammed went to make sure that our backflow device was up to code. He also took the time to explain what needed to be repaired in order to pass our annual test. He was reasonably priced and intentionally sought out ways for us to save money, while still making sure our device was properly tested. Excellent service. I will definitely call him again next year for our annual test. Highly recommend!Posted on Thomas Rizzo (TomR) The Tester showed up promptly and was done in minutes and put things back well enough.

Here’s something that’ll make you mad: You’ve been closing vents in unused rooms to save money, just like your dad taught you. Smart move, right? Wrong. Dead wrong. That ‘energy-saving’…
