Why Is My AC Blowing Warm Air in Raleigh's 27608 Area?
What the customer reported
The homeowner's upstairs unit was blowing air but not cooling effectively.
What we found and did
Dexter found that the pressure reading was off and discovered a stuck TXV along with a leak in the evaporator coil. Dexter conducted a thorough leak search at no charge due to the unit's age. He identified a stuck TXV and a leak in the evaporator coil, providing an estimate for their replacement under warranty.
Pro Tip
A stuck TXV can restrict refrigerant flow, causing your AC to blow warm air. If you notice this issue, act quickly to prevent further damage and potentially costly repairs.

Why Is My Apartment AC Leaking Oil in Raleigh?
What the customer reported
The leasing office reported excessive oil around the indoor evaporator coil insulation, and the system was not cooling properly.
What we found and did
Bernard found an excessive amount of oil accumulation at the connection between the aluminum coil and copper tubing, indicating a refrigerant/oil leak. The system was extremely low on refrigerant, likely due to a leak exacerbated by vibration. Bernard recommended keeping the system off to prevent further damage and advised the leasing office on obtaining quotes for either replacing the indoor evaporator coil or the entire system. He documented equipment details and assisted maintenance in adding refrigerant to another unit to keep it operational until a replacement could be arranged.
Result
The system was not cooling properly at the time of departure, and the leasing office awaited repair quotes.
Pro Tip
Excessive oil around your evaporator coil often signals a refrigerant leak. If you notice this, shut off the system to avoid compressor damage, which can be costly to repair.

What Caused My AC to Leak Oil in Raleigh's 27603 Area?
What the customer reported
A Raleigh apartment reported excessive oil coming from the air conditioning system, leading to concerns about a potential refrigerant leak.
What we found and did
Bernard found a significant oil accumulation at the connection point between the aluminum coil and copper tubing, suggesting a possible refrigerant/oil leak. Bernard inspected the rooftop condenser and monitored the system's operating pressures, which appeared normal. He advised the leasing office that a repair quote would be provided for replacing the indoor evaporator coil, with options for supply from either the property or the company.
Result
The system was cooling properly at the time of departure, but further repairs were recommended to prevent future issues.
Pro Tip
If you notice oil around your air conditioning unit, it may indicate a refrigerant leak. Addressing it promptly can prevent more severe issues like compressor failure.

What Caused My AC to Leak Refrigerant in Raleigh's 27609 Area?
What the customer reported
A homeowner in Raleigh's 27609 area experienced a persistent issue with their AC unit leaking refrigerant, leading to decreased cooling efficiency.
What we found and did
Jeorell discovered that the evaporator coil was leaking refrigerant and the outside unit was connected with the wrong size tubing, which contributed to the problem. Jeorell performed an electronic leak test to confirm the leaks in the evaporator coil. He recommended replacing the coil and suggested replacing the line set to prevent future issues, as the current setup included push fittings that could be eliminated with a new line set.
Result
The homeowner received a detailed quote for the necessary repairs and replacement, ensuring a plan for restoring their AC system's efficiency.
Pro Tip
If your AC is losing refrigerant, it might be due to a leaking evaporator coil. Addressing this early can prevent further damage and save on costly repairs down the line.
Why quality evaporator coil services matters in Raleigh
Extreme Summer Heat
Raleigh's hot, humid summers with temperatures often reaching 95°F+ put tremendous stress on HVAC systems. Systems must be properly maintained and sized to handle the extended cooling season from May through September.
Diverse Buildings
The city's diverse neighborhoods from downtown high-rises to suburban homes to historic properties each have unique HVAC needs. Our technicians are experienced with all building types and their specific challenges.
Building Permits
Wake County building codes and city permits have specific requirements for HVAC installations and replacements. We handle all permitting to ensure your system meets local compliance standards.
Urban Heat Island
Urban heat island effects in downtown Raleigh can increase cooling demands by 5-10 degrees compared to surrounding areas. This requires careful system sizing and efficient equipment selection.

Evaporator Coil Services in Raleigh: questions answered
Answered by our licensed technicians serving Raleigh.
How do I know if my evaporator coil needs service?
Common signs include reduced cooling, ice forming on the indoor unit, higher energy bills, or the system short-cycling. A temperature split test (measuring air temperature at supply and return vents) can quickly confirm coil issues.
Can a dirty evaporator coil be cleaned or does it need replacing?
In most cases, professional chemical cleaning restores performance. Replacement is recommended when coils have refrigerant leaks, severe corrosion, or when cleaning costs approach replacement value on older systems.
How long does an evaporator coil replacement take?
Most residential coil replacements are completed in 2 to 4 hours, including recovery of existing refrigerant, coil swap, brazing, pressure testing, and recharging the system.
Why does my evaporator coil keep freezing?
Freezing is typically caused by low refrigerant (from a leak), restricted airflow (dirty filter or failing blower), or a malfunctioning expansion valve. We diagnose and fix the underlying cause, not just the symptom.
Does replacing the evaporator coil require replacing the whole system?
Not usually. If the coil is matched to your existing condenser and furnace, standalone replacement is fine. However, if your system uses R-22 refrigerant or is 15+ years old, a full system upgrade may be more cost-effective.
