Dexter
August 2026
A homeowner in Chapel Hill was experiencing their air conditioning system blowing warm air during a particularly hot day.
Dexter found that the system had high superheat levels, indicating a malfunctioning TXV (Thermal Expansion Valve).
Dexter replaced the faulty TXV, ensuring the proper operation of the blower motor and system. He also checked the refrigerant levels, superheat, and subcooling to confirm the system's performance.
The air conditioning system was restored to proper functionality, providing cool air once again.
High superheat often indicates a TXV issue. If your AC starts blowing warm air, have a professional check the superheat levels to prevent larger system failures.
Mario
August 2026
The homeowner in Chapel Hill noticed their AC was blowing warm air instead of cooling the house.
Mario discovered that the indoor thermal expansion valve (TXV) was faulty, which was causing the system to malfunction.
Mario began by recovering all refrigerant from the system and moving necessary equipment to the outdoor unit's location. He replaced the faulty TXV with a new one and installed a new filter drier. After pressure testing and vacuuming the system, he recharged it with the correct amount of R-410A refrigerant and restored power.
The system was verified to be cooling properly, restoring comfort to the home.
A faulty thermal expansion valve can lead to warm air blowing from your AC. If you notice this issue, have a professional check the valve and refrigerant levels promptly to avoid more costly repairs.

The homeowner noticed that the back side of the first floor was not cooling effectively, leading to discomfort and high humidity levels.
Mario found that the dehumidifier's fan motor was seized, preventing it from functioning properly, although the furnace and condenser were operating as expected.
Mario confirmed the AC system was achieving a proper 22-degree temperature split and performed a load calculation. He determined that the area was compatible with a 4-ton system, as opposed to the current 3.5-ton unit. Mario discussed replacement options and informed the homeowner that an estimate for the fan motor replacement would be provided once further information was obtained.
The homeowner was informed about the system's limitations and potential improvements, with plans to address the dehumidifier issue.
A seized fan motor in your dehumidifier can lead to increased humidity and discomfort. If you notice your dehumidifier isn't working, check for unusual noises or lack of airflow — addressing it early can save on energy costs and improve comfort.
Jeorell
August 2026
A Chapel Hill homeowner noticed their air conditioner was not cooling effectively.
Jeorell found that the AC's compressor was no longer functioning properly.
Jeorell removed the old compressor from the roof and installed a new one along with a filter drier. He performed a pressure test to check for leaks and then pulled a vacuum to the manufacturer's specifications. Afterward, he added refrigerant 410a to the system and tested its operations.
The system was cooling efficiently at the time of Jeorell's departure.
A failing compressor can cause your AC to blow warm air. If you notice this, schedule a check-up immediately to prevent further damage and avoid higher repair costs.
Great service! Called in the afternoon after my AC stopped working. Friendly and very competent service person, Mario, fixed it the very next morning. He also installed a surge protector. I'm extremely satisfied!

Read articleChapel Hill's mix of historic homes and modern construction requires flexible HVAC solutions, from updating old systems to maintaining high-efficiency new installations.
The town's elevation changes and wooded areas create microclimates that affect home cooling needs differently across neighborhoods.
High humidity levels during summer months require proper dehumidification and regular maintenance to prevent mold and maintain indoor air quality.
Chapel Hill's focus on sustainability makes energy-efficient HVAC upgrades and smart thermostats especially valuable for homeowners.
Many Chapel Hill homes built in the 1980s and 1990s have original flex ductwork that has sagged, disconnected, or developed leaks, wasting 20-30% of cooled air before it reaches living spaces.
Chapel Hill's trend of adding additions and finishing basements often leaves the original AC system struggling to cool the expanded square footage.
Older Chapel Hill homes with single-pane windows and less insulation allow more moisture infiltration, overwhelming standard AC systems and creating indoor humidity problems.
Chapel Hill's mature tree canopy often grows too close to outdoor AC condensers, restricting airflow and reducing system efficiency by 10-15%.
More ways we can help in Chapel Hill.
Answered by our licensed technicians serving Chapel Hill.
Older Chapel Hill homes often have oversized AC systems that cool the air quickly but don't run long enough to remove humidity. Combined with original ductwork leaks pulling in unconditioned attic air, the result is a clammy feeling indoors. A properly sized modern system with variable-speed technology solves both issues.
For Chapel Hill homes with original 1980s or 1990s ductwork, we strongly recommend at least a duct inspection and sealing during AC replacement. About 60% of the Chapel Hill homes we service need some level of ductwork repair to get full performance from a new system.
Ductless mini-split systems are excellent for Chapel Hill's older and historic homes where ductwork is limited or damaged. For homes with existing ductwork, a variable-speed central system provides the best comfort and efficiency.
Replacing a 15+ year old system with a modern high-efficiency unit typically reduces cooling costs by 30-40%. For the average Chapel Hill home spending $138/month on energy, that translates to $400-$650 in annual savings on cooling alone.
