AC Problems Our Technicians Fix Across Durham

AC Blowing Warm Air

Usually low refrigerant, a dirty coil, or a capacitor on its way out. Sometimes it's a frozen coil that hasn't thawed yet. We find the exact cause and fix that, not just the symptom.

AC Short Cycling

Turning on and off in quick bursts puts real strain on your compressor. Usually a dirty filter, low refrigerant, or a thermostat that isn't reading the room right. It tends to get worse, not better, on its own.

Water Leaking Near the Indoor Unit:

Almost always a clogged condensate drain line. Durham's humidity puts more load on that drain than a drier climate would, which is exactly why this is one of our most common summer calls.

Frozen Coils or Ice on the Refrigerant Lines:

Airflow or refrigerant is off somewhere. Shut the system off and let it thaw. Running it while frozen can damage the compressor, which turns a repair into a much bigger bill.

AC Running Nonstop and Never Catching Up

Restricted airflow or a slow refrigerant leak, most often. Common in Durham homes with an addition built on at some point, since the addition and the original house often have different insulation and ductwork, and one system trying to satisfy both evenly is asking a lot.

AC Won't Start or Keep Tripping the Breaker:

Points to a failing capacitor, a worn contactor, or a control board issue. Durham gets its share of summer storms, and voltage spikes from storm activity cause more of these failures than people expect.

Grinding, Squealing, or Rattling Noises:

Your system telling you a motor bearing, a loose panel, or a blower component is wearing out before it fails completely. Catching it now is almost always cheaper than waiting.

Why Durham Homeowners Trust Alternative Aire

We Can Fix the Ductwork, Not Just Work Around It

A lot of uneven cooling and weak airflow complaints have nothing to do with the AC unit itself. The ductwork was never sized or sealed right in the first place. Most companies just patch around that. We design and fabricate custom ductwork in-house, so when that's the real problem, we actually fix it.

Licensed, Insured, NATE Certified

Fully licensed in North Carolina under NC H2 and H3-Class 1 #30223, with every technician on our team NATE certified.

High Efficiency and Dual Fuel Experience.

North Carolina swings between brutal summer heat and real winter cold, and we specialize in systems built to handle both.

17+ Years in This Community, BBB A+ Accredited

We've fixed enough AC systems in Durham to know which problems show up in which neighborhoods, and why.

A repair done right the first time means:

No repeat visits for the same problem a few weeks later
A system that isn’t quietly overworking itself while it “still runs fine”
Lower risk of a small issue turning into a compressor replacement
Cooler nights and fewer surprises on your energy bill

Financing for Your AC Repair

Not every repair is small, and we don’t expect everyone to cover a bigger fix all at once. That’s why we offer financing through the Wells Fargo Home Projects Credit Card, so you can get your system fixed now and pay over time instead of putting it off.

What financing through Alternative Aire actually gives you:

The option to pay over time instead of the full cost upfront
The same financing available for repairs, not just new installations

AC Repair FAQs

How can I tell if my HVAC system needs repair?

Watch for warm air from the vents, uneven cooling room to room, short cycling, strange noises, a climbing energy bill, or water near the indoor unit. Any one of these is worth a call. More than one at the same time means don’t wait.

Why is my AC blowing warm air?

Usually low refrigerant, a dirty coil, or a failing capacitor. A coil that’s frozen and hasn’t fully thawed can cause this too, temporarily.

Why is my AC leaking water?

Almost always a clogged condensate drain line. Algae and debris build up over time until the line backs up and starts dripping near the unit.

Should I repair my AC or replace it?

Under 10 years old with a reasonably priced repair, fix it. Older than that with a major failure, replacement usually makes more sense. We’ll give you the real numbers either way.

Do you offer same day AC repair in Durham?

In most cases, yes. Same day appointments are typically available, especially during peak summer months when waiting just isn’t an option.

How much does an AC diagnostic cost?

It depends on the system and what we find, so we’ll always confirm the cost with you before a technician comes out. You’ll know the price before anyone touches your system, not after.

Can you repair older AC systems in Durham's historic neighborhoods?

Yes, regularly. We work on systems throughout Old West Durham, Trinity Park, Forest Hills, and other neighborhoods where original ductwork and older equipment are common.

Do you repair Trane systems specifically?

Yes. We service Trane along with every other major brand, and we carry parts for common Trane repairs.
