Why Is My AC Blowing Warm Air in Knightdale?
The Problem
A Knightdale homeowner noticed that their AC system was not cooling the apartment as expected.
What We Found
Jeorell found that the AC system's pressures were dropping rapidly, indicating a potential leak.
The Fix
Jeorell hooked up gauges to the system and confirmed the pressure readings at 16 and 197 psi. Due to time constraints, a full leak search was not conducted immediately and a follow-up visit was scheduled to re-diagnose the system.
The Result
The issue was identified, but further inspection is needed to resolve the cooling problem.
Pro Tip
If your AC starts blowing warm air, it could be due to a refrigerant leak. Acting quickly can prevent further damage and costly repairs, so schedule a professional inspection as soon as possible.

AC Froze Up Overnight in Knightdale
The Problem
A Knightdale homeowner noticed their air conditioning unit was blowing warm air and the system had frozen up overnight.
What We Found
Travis discovered that the metering device and filter drier were malfunctioning, and the suction line was freezing due to improper refrigerant flow.
The Fix
Manny replaced the metering device and filter drier to restore proper refrigerant flow. The refrigerant circuit was evacuated to remove moisture and gases, then recharged to the manufacturer's specifications. Travis conducted a compressor replacement, installed a new Thermostatic Expansion Valve (TXV), and performed a pressure test to ensure system integrity.
The Result
The system was restored to normal operation with appropriate pressures and temperatures.
Pro Tip
If your AC's suction line starts to frost, it might indicate a refrigerant flow issue. Address it promptly to avoid compressor damage, which can be costly to repair.

AC Froze Up Overnight in Knightdale
The Problem
A homeowner in Knightdale noticed their air conditioning unit had frozen up overnight, causing discomfort during the hot summer weather.
What We Found
Travis determined that the compressor was failing to pump refrigerant steadily, leading to pressure fluctuations and a frozen line.
The Fix
Travis identified that the initial restriction was resolved, but the compressor's failure was now evident. He recommended a system replacement due to the age of the unit, as a compressor repair might not be a long-term solution. A quote for a new system was arranged to be sent to the homeowner.
The Result
The homeowner received a recommendation for a new system to ensure reliable cooling.
Pro Tip
If your AC line freezes, it might be due to a failing compressor. Addressing this early can prevent further damage and costly repairs. Consider a full system replacement if your unit is aging and repairs are becoming frequent.

Why Is My AC Blowing Warm Air in Knightdale?
The Problem
An Knightdale homeowner noticed that their air conditioning unit was blowing warm air instead of cooling the home.
What We Found
Jeorell and Travis discovered that the unit's coil filter drier needed replacement and the refrigerant required conversion from R-22 to a substitute.
The Fix
Jeorell installed a new coil filter drier and performed a nitrogen test on all lines. The unit was then vacuumed, and 422B refrigerant was added to replace the outdated R-22. These steps ensured the unit was properly set up for efficient cooling.
The Result
The air conditioning unit was restored to full functionality, effectively cooling the home once again.
Pro Tip
If your AC starts blowing warm air, it might be time to check if the refrigerant needs conversion. Older systems using R-22 can often benefit from a switch to a more modern substitute like 422B.

FAQ
AC Repair in Knightdale: questions answered
Answered by our licensed technicians serving Knightdale.
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.
