The Chill Brothers started in Texas in 2020 and grew into a Lennox Premier Dealer known for AC repair, AC installation, furnace service, indoor air quality work, and commercial HVAC.
We came into North Carolina in 2025 by acquiring Alternative Aire, a Durham HVAC company founded in 2011, in April of that year. Two months later we opened a dedicated Raleigh-Durham office, and by November we had also acquired Tower Heating, Air and Plumbing, a Raleigh based company in Wake County. That branch now runs out of 3131 RDU Center Dr in Morrisville, dispatching technicians to Raleigh, Durham, Cary, Morrisville, Charlotte, Asheville, Greensboro, Winston-Salem, High Point, Hickory, Fayetteville, and Wilmington. Across all of our locations we have completed more than 10,000 installs and hold a 4.7 star rating from over 3,125 verified Google reviews.
We handle residential and commercial heating and cooling work, not just one or the other.
North Carolina summers keep AC systems under load for months at a stretch. We repair units that are struggling to keep up, install new systems, and run the tune ups that keep small issues from becoming big ones.
Winter in North Carolina is not one thing. It is mild in the Piedmont and genuinely cold in the mountains and foothills, and both furnaces and heat pumps take a beating from that range. We work on both.
Humidity does not take a season off in most of North Carolina. Our indoor air quality work is about keeping the air clean and the moisture in check year round.
Rooftop units, split systems, and packaged equipment for businesses of any size.
Our Morrisville branch sends technicians out across the Triangle and beyond. We currently cover:

Our technicians see the same handful of problems on repeat across the state. Here is what usually causes each one.
This is the complaint we hear most often, especially closer to the coast and through the Piedmont. Three things usually explain it: the system is oversized and shuts off before it has run long enough to pull moisture out of the air, the evaporator coil is dirty, or the blower is set to move air faster than it should for good dehumidification. We can usually tell which one it is during a single visit. If your ductwork is undersized, that will make it worse regardless of the system itself. Our Duct Size Calculator is a quick way to check.
Once temperatures drop into the 30s, which happens routinely in the mountains and foothills and now and then even in the Piedmont, a heat pump has to work harder to hold temperature. If yours is running nonstop and still falling short, check for low refrigerant, a unit stuck in a defrost cycle, or a system that was undersized for how cold your area actually gets in a hard winter. A failed backup heat strip is another one we run into often.
Very common in two story homes across North Carolina. Usual causes are an imbalance in the ductwork, return air that is too small for the system, gaps in attic insulation, or dampers that are not set right. A zoning system fixes this for good in most cases. If you are not sure whether your system was even sized correctly to begin with, our AC Size Estimator will give you a real answer.
A system that has to work harder runs longer, and that shows up on your bill fast. Low refrigerant, dirty coils, a failing capacitor, or a thermostat that has drifted out of calibration are the usual causes. A diagnostic visit tells us which one within the hour.
Grinding is almost always a motor bearing on its way out. Banging usually means a loose blower wheel or a compressor issue. Hissing points to a refrigerant leak. None of these get better on their own, and waiting almost always turns a cheap fix into an expensive one.
Past ten years old, needing a major part like a compressor or coil, or still running on R-22 refrigerant are the three signs that usually point toward replacement. A newer system with a single failed part is almost always worth repairing instead. We show you both numbers honestly and let you make the call, because it is your money either way.
Free estimate
We come out to your North Carolina home, look at what you actually need, and hand you a written quote before anything gets scheduled. No fees for the visit, no fine print, no pressure to decide on the spot.
The work itself
A certified, background checked technician does the job cleanly, whether that is a full install or a same day repair. We treat your house the way we would want ours treated.
Final walkthrough
Before we leave, we walk the finished work with you, confirm the system is running the way it should, and hand over the paperwork, so you know exactly what was done.
Humid summers and cold snaps both take a toll on HVAC equipment in North Carolina. A maintenance plan is one of the cheaper ways to avoid a midsummer breakdown, and it tends to pay for itself in lower energy bills alone.
A failing system should not turn into a financial emergency. Our financing options include:
Ask our team which option makes the most sense for your situation. We will tell you honestly, not just sell you the biggest package.
None of the following are self awarded. They come from Lennox, NATE, and independent review and rating organizations.
Answered by our senior technicians, who between them have decades of hands on experience working North Carolina homes.
Most jobs land somewhere between $150 and $900. A capacitor or contactor is on the cheap end. Compressor or coil work is on the expensive end. Whatever it is, you get a written number before we touch anything.
Generally $6,000 to $15,000, depending on the size of the system, its efficiency rating, and how your existing ductwork is set up. Between the Buy-Back program and 0% financing, most people end up paying less per month than they expected walking in.
In most of the state, yes, without much drama. A good variable speed heat pump handles Piedmont and coastal winters fine. Once you get up into the mountains and foothills where it gets genuinely cold, we usually recommend pairing it with backup heat strips or going with a dual fuel setup so the coldest weeks are not an issue.
Twice a year is the right cadence. Cooling maintenance before summer hits, heating maintenance before the first cold snap. If you are on our maintenance plan, we will call to remind you so it does not slip through the cracks.
Almost always one of three things: the system is oversized and shuts off before it pulls enough moisture out, the evaporator coil is dirty, or the blower is running faster than it should. We check all three on a service visit. Some homes genuinely need a whole home dehumidifier alongside the AC, and we will tell you straight if yours is one of them.
Past ten years old, a major failed part like a compressor or coil, or still on R-22 refrigerant, all point toward replacement being the better financial move. A newer system with one bad part is usually worth fixing. We give you real numbers on both paths.

Jason is an excellent and very knowledgeable technician. He explains things in detail to where I have an option for new equipment, possibly$0 out of pocket. I'll be listing my home soon and will be a to increase equity with new equipment and the sale may cover costs (if I related that correctly). We'll see when I have a sit down with the manager. I received excellent service today, regardless. Thanks, Jason.Trustindex verifies that the original source of the review is Google.
We experienced a complete failure due to a power surge. Ended up with two technicians working on replacing parts inside and outside. They stayed late and didn’t leave until we had the AC restored. Really appreciate above and beyond service.Trustindex verifies that the original source of the review is Google.
