What Caused My Thermostat to Go Blank in Chapel Hill?
What the customer reported
A Chapel Hill homeowner experienced a blank thermostat display, indicating a loss of power.
What we found and did

The technicians cleared the drain line to prevent further tripping of the safety switch. They advised that if the issue persisted, installing a pan safety switch might be necessary to prevent future power interruptions.

A filled drain line can cause your thermostat to lose power. If your thermostat goes blank, check for clogs in the drain line to avoid unnecessary service calls.

He then jumped the motor, which caused the blower motor to work, indicating that the control board needed replacement.
Result
The homeowner was informed of the need for a new control board to restore full functionality.
Pro Tip
If your blower motor stops working, it might be due to a faulty control board. Testing the motor by jumping it can confirm this, helping you avoid unnecessary part replacements.

Why Is My AC Blowing Warm Air in Chapel Hill?
What the customer reported
The homeowner in Chapel Hill was experiencing a lack of cold air from their HVAC system.
What we found and did
Bernard found that the outdoor condenser was not operating due to a blown 20-amp fuse and the system was low on R-410A refrigerant. Bernard replaced the blown fuse and added refrigerant to the system to bring the pressures into the appropriate operating range. He also recommended monitoring the system for continued operation and addressing the deteriorated supply ductwork.
Result
The HVAC system became operational, providing a cooling temperature split of approximately 18–22°F.
Pro Tip
A blown fuse in your AC system can stop it from cooling effectively. If you notice your system blowing warm air, it might be a simple fix like replacing a fuse, which can save you from 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.
