Daikin Mini-Split Not Cooling in Durham
The Problem
The Daikin mini-split in the elevator room was not providing adequate cooling.
What We Found
Mario found that the unit was low on R-410A and identified a leak at the evaporator coil.
The Fix
Mario cleared the drainage issue and tested the voltage. He performed a leak search and confirmed the evaporator coil leak using a leak detector. Due to the unit's age and potential for further issues, he recommended a full replacement and will send a formal estimate.
The Result
The unit remains non-operational, and a replacement is advised to ensure reliable cooling.
Pro Tip
If your mini-split system stops cooling, it might be low on refrigerant due to a leak. Address leaks promptly to prevent further damage and avoid costly repairs.

Why Did My AC Stop Cooling in Durham?
The Problem
A homeowner in the 27707 area noticed that their AC system was not maintaining the set temperature.
What We Found
Dexter discovered that the common wire was grounded, which caused both 20-amp fuses to fail. Additionally, the 35/5 capacitor needed replacement.
The Fix
Dexter recommended replacing the grounded common wire, the failed fuses, and the faulty capacitor. After replacing these components, he retested the system to ensure it was operating correctly and providing proper cooling performance.
The Result
The AC system was restored to full functionality, effectively cooling the home as expected.
Pro Tip
If your AC isn't cooling, check for signs like a tripped breaker or unusual noises. These can indicate issues like a grounded wire or a failing capacitor, which should be addressed promptly to prevent further damage.

What Caused My AC to Stop Cooling in Durham?
The Problem
The homeowner in Durham noticed their AC was blowing warm air despite the thermostat being set to cool.
What We Found
Mario identified that the outdoor unit was not exhausting air properly due to a failed capacitor and low refrigerant levels.
The Fix
Mario replaced the faulty dual run capacitor with a new 40+5 capacitor and added refrigerant to the system. He then performed a post-repair diagnostic to ensure system pressures were normal and confirmed a 20°F temperature drop across the indoor coil.
The Result
The AC system was restored to full operation, cooling effectively and running safely.
Pro Tip
If your AC is blowing warm air, a failed capacitor might be the culprit. Listen for a humming noise without the fan turning — it's a sign the capacitor needs attention before it leads to bigger issues.

AC Running Heat Mode in Durham
The Problem
The homeowner noticed that their AC was blowing warm air instead of cooling their home.
What We Found
Dexter and Jeorell discovered that the heat strip was running simultaneously with the AC due to several 24v wires being swapped and a bundle spliced outside of the conduit.
The Fix
They traced the power source and found that the issue stemmed from the AC unit, where the white wire was not connected in the condenser. They corrected the wiring, ensuring that the connections were properly aligned and secured, preventing the heat strip from activating with the AC.
The Result
The AC system was restored to proper function, providing cool air as expected.
Pro Tip
If your AC is blowing warm air, check for unusual wiring or splices. Miswired connections can cause components like heat strips to run when they shouldn’t, leading to uncomfortable indoor temperatures.

Why Quality Air Conditioning Matters in Durham
Historic to Modern
Durham's diverse housing stock ranges from historic homes to modern builds, each requiring different HVAC approaches and solutions.
Bull City Summer Heat
The Bull City's hot, humid summers with temperatures often exceeding 90°F demand reliable AC systems with proper maintenance schedules.
Retrofitting Challenges
Many older Durham homes have ductwork that wasn't designed for central AC, requiring creative solutions and expert retrofitting.
Outdoor Unit Care
Durham's tree-lined neighborhoods provide shade but also shed debris that can clog outdoor AC units, requiring regular cleaning and maintenance.
Common Air Conditioning Issues in Durham
Humidity Damage to AC Components
Durham's mixed-humid climate causes accelerated corrosion on evaporator coils and condensate drain issues, particularly in homes where regular maintenance has been deferred.
Duct Leaks in Older Durham Homes
Homes in established Durham neighborhoods like Hope Valley, Forest Hills, and Woodcroft often have deteriorated duct connections that leak 25-40% of conditioned air into crawlspaces and attics.
Mismatched Systems After Partial Replacements
Some Durham homeowners replace only the outdoor condenser or indoor unit, creating a mismatched system that reduces efficiency and can void manufacturer warranties.
Diverse Housing Stock Requiring Custom Solutions
Durham's range from 1940s bungalows to 2020s construction means there's no one-size-fits-all AC solution—each home needs individual assessment for proper cooling.

Frequently Asked Questions About Air Conditioning in Durham
Answered by our licensed technicians serving Durham
How does Durham's humidity affect my AC system?
Durham sits in climate zone 4A (mixed-humid), meaning your AC does double duty—cooling air AND removing moisture. This extra load accelerates wear on compressors and coils. Systems in Durham typically last 12-15 years. Variable-speed systems handle our humidity much better than single-stage units.
My Durham home has uneven cooling—what's wrong?
Uneven cooling is the #1 complaint we hear from Durham homeowners. In older homes (Hope Valley, Forest Hills), it's usually leaky ductwork. In newer homes, it's often a single-zone system trying to cool a multi-level layout. We diagnose the specific cause and recommend the most cost-effective solution.
Are ductless mini-splits good for Durham homes?
Mini-splits are excellent for many Durham homes, especially older homes without ductwork, homes with additions, or as a supplement for hot rooms. They're also ideal for Durham's many rental properties since they allow zone-by-zone control.
What does AC maintenance cost in Durham?
Annual AC maintenance in Durham typically runs $89-$199 depending on system type and age. Given Durham's humidity and pollen levels, annual maintenance is essential—it extends system life, prevents breakdowns, and keeps efficiency high.
