Cooling Failed on a 100° Day in Chapel Hill
The Problem
A homeowner in Chapel Hill was experiencing their air conditioning system blowing warm air during a particularly hot day.
What We Found
Dexter found that the system had high superheat levels, indicating a malfunctioning TXV (Thermal Expansion Valve).
The Fix
Dexter replaced the faulty TXV, ensuring the proper operation of the blower motor and system. He also checked the refrigerant levels, superheat, and subcooling to confirm the system's performance.
The Result
The air conditioning system was restored to proper functionality, providing cool air once again.
Pro Tip
High superheat often indicates a TXV issue. If your AC starts blowing warm air, have a professional check the superheat levels to prevent larger system failures.

Why Is My AC Blowing Warm Air in Chapel Hill?
The Problem
The homeowner in Chapel Hill noticed their AC was blowing warm air instead of cooling the house.
What We Found
Mario discovered that the indoor thermal expansion valve (TXV) was faulty, which was causing the system to malfunction.
The Fix
Mario began by recovering all refrigerant from the system and moving necessary equipment to the outdoor unit's location. He replaced the faulty TXV with a new one and installed a new filter drier. After pressure testing and vacuuming the system, he recharged it with the correct amount of R-410A refrigerant and restored power.
The Result
The system was verified to be cooling properly, restoring comfort to the home.
Pro Tip
A faulty thermal expansion valve can lead to warm air blowing from your AC. If you notice this issue, have a professional check the valve and refrigerant levels promptly to avoid more costly repairs.

Why Is My AC Struggling in Chapel Hill's Humidity?
The Problem
The homeowner noticed that the back side of the first floor was not cooling effectively, leading to discomfort and high humidity levels.
What We Found
Mario found that the dehumidifier's fan motor was seized, preventing it from functioning properly, although the furnace and condenser were operating as expected.
The Fix
Mario confirmed the AC system was achieving a proper 22-degree temperature split and performed a load calculation. He determined that the area was compatible with a 4-ton system, as opposed to the current 3.5-ton unit. Mario discussed replacement options and informed the homeowner that an estimate for the fan motor replacement would be provided once further information was obtained.
The Result
The homeowner was informed about the system's limitations and potential improvements, with plans to address the dehumidifier issue.
Pro Tip
A seized fan motor in your dehumidifier can lead to increased humidity and discomfort. If you notice your dehumidifier isn't working, check for unusual noises or lack of airflow — addressing it early can save on energy costs and improve comfort.

AC Compressor Malfunctioned in Chapel Hill Home
The Problem
A Chapel Hill homeowner noticed their air conditioner was not cooling effectively.
What We Found
Jeorell found that the AC's compressor was no longer functioning properly.
The Fix
Jeorell removed the old compressor from the roof and installed a new one along with a filter drier. He performed a pressure test to check for leaks and then pulled a vacuum to the manufacturer's specifications. Afterward, he added refrigerant 410a to the system and tested its operations.
The Result
The system was cooling efficiently at the time of Jeorell's departure.
Pro Tip
A failing compressor can cause your AC to blow warm air. If you notice this, schedule a check-up immediately to prevent further damage and avoid higher repair costs.

FAQ
AC Repair in Chapel Hill: questions answered
Answered by our licensed technicians serving Chapel Hill.
How quickly can you get to my home for an AC repair?
For standard AC repairs in the Apex, Cary, Raleigh, and surrounding areas, we typically offer same-day or next-day service. During peak summer months (June-August), demand is highest, so we recommend calling early in the day. Emergency repairs are prioritized and dispatched as quickly as possible.
How much does an AC repair cost?
Repair costs depend on the specific problem and parts needed. A capacitor replacement might run $150-$300, while a compressor replacement can range from $1,500-$2,500+. We charge a diagnostic fee to identify the problem, then provide a flat-rate repair quote before proceeding. The diagnostic fee is waived if you approve the repair.
Is it worth repairing my older AC system?
As a general guideline, if a repair costs more than 50% of a new system and your equipment is over 10 years old, replacement often makes more financial sense. We'll give you an honest assessment factoring in your system's age, repair history, efficiency, and the cost of the specific repair needed.
Why did my AC stop working on the hottest day?
This is extremely common. Peak heat days push your system to maximum capacity for extended periods. Components like capacitors, compressors, and fan motors that are already weakened by wear are most likely to fail under this extreme stress — similar to how a worn tire is most likely to blow out on a long highway drive.
