AC Not Cooling Properly in Chapel Hill Apartment
The Problem
A Chapel Hill homeowner reported their AC was leaking water and not cooling effectively.
What We Found
Dexter found that insulation was being pulled into the system, obstructing airflow, and noted high superheat levels.
The Fix
Dexter sealed the insulation to restore proper airflow and verified that the refrigerant pressures were optimal. He also identified and recommended replacing the weatherstripping on the front door to prevent hot air from entering the apartment.
The Result
After the repairs, the AC system was blowing cold air efficiently, and the temperature inside the home stabilized.
Pro Tip
If your AC isn't cooling properly, check for gaps around doors and windows where hot air might enter. Sealing these can improve efficiency and comfort.

Thermostat Stuck on a Saturday Morning in Chapel Hill
The Problem
A Chapel Hill homeowner reported that their AC system was set to cool but was instead heating the home.
What We Found
Jeorell discovered that the plug for the reversing valve was loose, causing the system to malfunction.
The Fix
Jeorell made a proper connection for the reversing valve plug, which allowed the system to start cooling effectively. Additionally, the customer-supplied compressor was replaced, and the system was vacuumed and recharged to ensure optimal performance.
The Result
The system was cooling properly by the time Jeorell left the site.
Pro Tip
If your thermostat settings don't match your HVAC's actions, check for loose or disconnected wires in the system. A simple reconnection might save you from unnecessary discomfort.

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.

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.
