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 The unit was then vacuumed, and 422B refrigerant was added to replace the outdated R-22.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.
Travis
July 2026
A homeowner in Knightdale noticed their AC unit was not cooling properly, causing the apartment to become uncomfortably warm.
Travis found that while the compressor was running fine, the low side was restricted, leading to the evaporator coil freezing up.
Travis unplugged the unit to allow the ice to melt and restore proper airflow temporarily. He recommended replacing the TXV and filter dryer to prevent future restrictions and left estimates for both a repair and a full system replacement.
The immediate issue was temporarily resolved, but a more permanent fix was advised to prevent recurring problems.
If your evaporator coil keeps freezing, it might be due to a restricted low side. Consider replacing the TXV and filter dryer to ensure smooth refrigerant flow and prevent ice build-up.
Jeorell & Dexter
July 2026
A Knightdale homeowner noticed their air conditioning system was not cooling properly, and the unit had frozen up.
Jeorell found that the system's pressures were low and identified a bad capacitor in the unit.
Jeorell informed the leasing office about the low pressures and noted that the system had been converted to use R454A refrigerant. He replaced the faulty capacitor and tested the system to ensure it was cooling properly before leaving.
The air conditioning system was cooling effectively at the time of departure.
If your AC unit freezes up, it might be due to low refrigerant levels or a bad capacitor. Address these issues promptly to prevent further damage and ensure efficient cooling.
Travis, Jeorell & Tay
June 2026
The homeowner noticed that the outdoor unit was not level, which was affecting the cooling efficiency.
Jeorell and Travis found that the unit we installed had become unlevel, impacting its performance.
Jeorell and Travis leveled the unit by adding rocks to the base and installing vibration pads. They ensured the system was level on all four sides before leaving.
The cooling system was properly leveled and functioning efficiently upon departure.
If your outdoor unit becomes unlevel, it can affect performance and efficiency. Regularly check the unit's level and use a carpenter's level to ensure all sides are even.
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.
More ways we can help in Knightdale.
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.
