- AC Installation Durham, NC
Reliable AC Installation Services in Durham, NC
Most AC installers will look at your old unit, order the same size, and call it a day. That's how you end up with a system that runs nonstop and still can't cool the upstairs, or one that blasts cold air so fast it never pulls the humidity out of the house. We start every installation with an actual load calculation instead of a guess, and it's the reason our installs work the way they're supposed to for years, not just the first summer.
Trusted AC Installation Company in Durham
An AC system is one of the bigger investments you’ll make in your home, and it only pays off if it’s sized and installed correctly from the start. We handle every installation ourselves, our own NATE certified technicians, not a crew brought in for the day, working from a real assessment of your home instead of a one size fits all quote. Whether you need a straightforward central AC swap or something more involved, like a ductless setup for a room your current system can’t reach, we walk you through the options honestly before any work begins.
Our AC Installation Services in Durham
Central AC Rapier
This is what most Durham homes end up with, and there's a reason for that. A properly sized central system, set up with the right airflow and refrigerant charge, cools the whole house evenly instead of overworking whatever room the thermostat happens to sit in. We test it under load before we leave, not just flip it on and check the box.
Ductless Mini Split Installation
If you're in one of the older homes around Old West Durham, there's a decent chance the ductwork was never built to support a full central retrofit, or there isn't any at all in that sunroom your family added on. Mini splits solve that without making your main system fight to reach space it was never designed for. We also install these often in the bigger homes out near Southpoint and Hope Valley, where one thermostat can't keep every room comfortable at the same time.
High Efficiency and Dual Fuel Systems
North Carolina doesn't make this easy on a system. Summers are humid and long, and winters still throw a hard freeze at you when you least expect it. Dual fuel and high efficiency setups are built for exactly that kind of swing, and it's genuinely what we're best at.
Full System Replacement
Sometimes the AC is past the point where fixing it makes sense, constant breakdowns, an aging refrigerant type that's getting harder to source, a compressor that's already failed once. When that's where things stand, we replace the whole system the same way we handle every install, sized right and tested before we call it done.

We run the system under load, confirm everything's performing right, and walk you through the thermostat so you're not guessing at settings for the next six months.
Why Durham Homeowners Choose Alternative Aire
Most installers will hook a new AC up to whatever ductwork is already in the walls, even when that ductwork is half the reason the old system never worked right in the first place. We design and fabricate our own ductwork, so when that’s actually part of your problem, we fix it instead of building a new system on top of an old mistake.
We’re licensed in North Carolina under NC H2 and H3-Class 1 #30223, and every technician on our team is NATE certified. Not a subcontractor’s certification. Ours. We’ve been doing this in Durham for 17 years, we’re Durham Living Wage Certified, and we carry a BBB A+ rating. None of that guarantees a flawless job every single time. But it does mean there’s an actual, accountable company behind the work if something needs a second look.
A properly installed system does more than just cool the house. It means:
- Sleeping through a Durham summer night without one room running hot
- Lower energy bills from a system that isn’t fighting its own size
- Fewer repeat repair calls because it was set up right on day one
- Even airflow across every room, not just the one near the thermostat
- A system actually built to handle Durham’s humidity, not just the temperature
- Quieter operation than a unit that’s straining to keep up
Financing Options for Your AC Installation
A new AC system is a real expense, and we don’t expect everyone to pay for it all at once. That’s why we offer financing through the Wells Fargo Home Projects Credit Card, so you can move forward with an installation or a repair without draining your savings to do it.
What financing through Alternative Aire actually gives you:
- The option to pay over time instead of covering the full cost upfront
- The same financing available for repairs, not just new installations
- A straightforward application, not a runaround
- One less reason to put off a repair or replacement your home actually needs

AC Installation FAQs
How long does AC installation take?
Most residential jobs wrap up in a single day. If there’s ductwork to modify or an electrical upgrade involved, it can run into a second day, and we’ll tell you upfront if that’s likely before we start.
How do I know what size AC I actually need?
Not from your square footage alone, and definitely not from just matching your old unit. We factor in insulation, window placement, ceiling height, and layout before we recommend anything. That’s the load calculation, and skipping it is how most sizing problems happen in the first place.
What does this actually cost?
It depends on the system size, the efficiency level, what shape your ductwork and electrical setup are in, and the brand you go with. We give you a real written quote after we’ve actually seen your home, not a number over the phone.
Do you offer financing?
Yes, through the Wells Fargo Home Projects Credit Card, and it works for both installation and repair costs.
Should my furnace get replaced at the same time?
If it’s older or wasn’t built to pair well with a higher efficiency AC, doing both together usually performs better and can make the install itself more straightforward. We’ll tell you honestly whether your current furnace is a good match before we suggest replacing it too.
What's SEER2, and does it actually matter?
It’s the current industry standard for rating cooling efficiency, replacing the older SEER system a few years back. Higher SEER2 means better efficiency and a higher price tag upfront. We’ll walk through the real tradeoff with you instead of just handing you a number.
Can I get a new AC without replacing my ductwork?
Often, yes, as long as what’s there is sized right and properly sealed. If it’s leaking or undersized, which is common in a lot of the older housing stock around Old West Durham, we’ll flag it during the estimate and can design a real fix instead of working around it.
Will a new system actually lower my bills?
Usually, especially if your old one was the wrong size to begin with. How much depends on your home’s insulation and how you actually use the system day to day, so we won’t throw out a specific savings number without seeing the house first.
What brands do you carry?
Trane, Lennox, Carrier, Goodman, York, and American Standard.
How long should a new AC last?
With regular maintenance, most central systems run 12 to 15 years. Getting the sizing and installation right on day one has a lot to do with whether you hit that number or fall short of it.
