Jeorell
August 2026
A Knightdale homeowner noticed that their AC system was not cooling the apartment as expected.
Jeorell found that the AC system's pressures were dropping rapidly, indicating a potential leak.
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 issue was identified, but further inspection is needed to resolve the cooling problem.
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.
Manny & Travis
August 2026
A Knightdale homeowner noticed their air conditioning unit was blowing warm air and the system had frozen up overnight.
Travis discovered that the metering device and filter drier were malfunctioning, and the suction line was freezing due to improper refrigerant flow.
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 system was restored to normal operation with appropriate pressures and temperatures.
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.
Travis
July 2026
A homeowner in Knightdale noticed their air conditioning unit had frozen up overnight, causing discomfort during the hot summer weather.
Travis determined that the compressor was failing to pump refrigerant steadily, leading to pressure fluctuations and a frozen line.
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 homeowner received a recommendation for a new system to ensure reliable cooling.
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.
Jeorell & Travis
July 2026
An Knightdale homeowner noticed that their air conditioning unit was blowing warm air instead of cooling the home.
Jeorell and Travis discovered that the unit's coil filter drier needed replacement and the refrigerant required conversion from R-22 to a substitute.
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 air conditioning unit was restored to full functionality, effectively cooling the home once again.
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.
They came out for our biannual HVAC maintenance. Manny was super kind and professional. He noticed that our compressor was going and quoted us or said we can wait until it goes. The price was very reasonable compared to us waiting for the AC to go. Would recommend them

Read articleKnightdale subdivisions like Planters Walk and Poplar Creek Estates built between 2000-2012 have original AC units now 12-20 years old, well past peak efficiency and increasingly prone to compressor failures during hot summers.
Many Knightdale homes in Widewaters and Langston Ridge feature two-story layouts where second-floor bedrooms run 5-8 degrees warmer due to inadequate ductwork design or single-zone systems that cannot balance the load.
Newer Knightdale homes in Mingo Creek and Station at Knightdale are built to modern energy codes with tight envelopes, which can trap moisture indoors and cause the AC to struggle with humidity removal if not properly configured.
Knightdale sits in climate zone 4A where summer humidity regularly exceeds 70%, forcing AC systems to work overtime removing moisture in addition to cooling — shortening equipment lifespan and increasing energy bills.

Answered by our licensed technicians serving Knightdale.
Most Knightdale homes built during the 2000s boom are now entering the AC replacement window. Systems typically last 12-15 years in our climate zone 4A, so homes in Planters Walk and Poplar Creek Estates are due for evaluation. We recommend a system assessment once your unit hits 10 years.
This is very common in Knightdale two-story homes, especially in Widewaters and Langston Ridge. The issue is usually single-zone systems combined with inadequate return air upstairs. Solutions range from adding a zone control system to installing a ductless mini-split on the second floor.
Duke Energy Progress offers efficiency rebates for qualifying high-SEER AC installations. Combined with federal tax credits for Energy Star systems, Knightdale homeowners can save $500-$2,000 on a new AC. We handle the Duke Energy rebate paperwork for you.
AC replacement in Knightdale ranges from $4,500 to $8,500 depending on system size, efficiency rating, and ductwork needs. Most Knightdale homes need a 3-4 ton system. We provide free estimates with upfront pricing and financing.
