Dexter
August 2026
A homeowner in Cary noticed water dripping from the first-floor AC unit.
Dexter found growth on the evaporator coil, causing water to drip inside the system and accelerating rust. Both capacitors were also out of specification.
Dexter cleaned the evaporator coil to remove the growth and prevent further water leakage. He replaced the capacitors to ensure the system operated efficiently. These adjustments helped maintain the cooling effectiveness of the unit.
The AC system resumed proper operation, cooling effectively without leaks.
If you see rust or water near your AC unit, check for evaporator coil issues. Addressing these early can prevent costly damage and keep your system running smoothly.

The homeowner noticed that their cooling system was not effectively cooling the house, especially during a particularly hot day.
Dexter found that the capacitor was weakening and the original contactor was pitted, reducing voltage to the system.
Dexter and Aaron performed maintenance by cleaning the coil and checking all components. They suggested replacing the capacitor and contactor to prevent further issues and improve system efficiency. They also recommended installing a UV element to improve indoor air quality and reduce contaminants.
The cooling system was restored to optimal performance, ensuring the home remained cool and comfortable.
If your AC struggles to cool on hot days, it might be a weakening capacitor or pitted contactor. Replacing them early can save you from a complete system failure.
Dexter
August 2026
The homeowner noticed that the AC on the second floor was not cooling effectively.
Dexter found that the capacitor on the second-floor unit was losing its charge.
Dexter performed maintenance on both AC systems, ensuring all components were functioning correctly. He cleaned the coils and checked the capacitors and amps. He advised replacing the weakening capacitor and suggested installing UV and surge protection for the upstairs unit.
The AC systems were thoroughly maintained, and the homeowner was informed about potential improvements.
A capacitor losing charge can lead to inefficient cooling. If your AC isn't cooling well, have a technician check the capacitors — they're essential for starting and running the motor efficiently.
Dexter & Aaron
August 2026
An apartment manager in Cary noticed that the HVAC system was not functioning properly and suspected an issue with the control box.
Dexter found that the control box had melted due to the age-related failure of the control board, which shorted and overheated.
Upon approval from the apartment manager, Dexter and Aaron replaced the damaged control box with a new one, ensuring all connections were secure and the system was tested for functionality.
The HVAC system was restored to full working order, providing reliable service again.
A melted control box often signals an underlying electrical issue. If you notice any unusual odors or system malfunctions, it's crucial to have a professional inspect the system promptly to prevent further damage.
Got a PRV valve, new main shutoff, and new toilet shutoff. Chris is great. Fast and good quality work. Plan on using Element for all future plumbing repairs.

Read articleCary's suburban growth and tree canopy create unique airflow challenges, requiring properly sized HVAC systems to efficiently cool multi-story homes.
The area's humid subtropical climate with 90°F+ summer temperatures demands high-efficiency AC systems to manage energy costs and maintain comfort.
Many Cary neighborhoods built in the 1990s-2000s have aging HVAC systems nearing replacement age, making preventive maintenance critical.
Local HOA regulations in Cary's planned communities often require specific equipment placement and noise level compliance for outdoor AC units.
HVAC systems in Cary's established neighborhoods require more thorough maintenance as they age, with electrical components, motors, and refrigerant connections all more prone to failure after 15 years.
Older Cary homes with R-22 refrigerant systems need careful leak monitoring during maintenance, as even small leaks become extremely expensive to repair with phased-out refrigerant.
Cary's tech-corridor professionals often neglect regular filter changes, leading to restricted airflow, frozen coils, and premature compressor failure.
Twenty-year-old ductwork in Cary homes develops loose connections, torn insulation, and sagging flex duct that maintenance visits can identify before they cause significant energy waste.

Answered by our licensed technicians serving Cary.
Yes, but with realistic expectations. Maintenance on a 20-year-old system keeps it running as long as possible while we monitor for signs of impending major failures. It also gives us the opportunity to help you plan for replacement rather than facing an emergency situation. Many Cary homeowners get 2-5 additional years from well-maintained older systems.
During maintenance, we measure performance metrics like temperature differential, refrigerant pressures, and electrical draw. If these values fall outside acceptable ranges—common in Cary homes with 15+ year systems—we'll honestly tell you whether repair or replacement is the better investment.
We recommend our comprehensive plan that includes two visits per year (spring and fall), priority scheduling, 15% discount on repairs, and no overtime charges. For Cary homes with older systems, this plan often pays for itself with a single prevented emergency call.
Yes. We inspect accessible ductwork connections during every maintenance visit. For Cary homes with 20-year-old ductwork, we often find disconnected joints, torn insulation, and sagging flex duct that waste energy. We can seal minor issues during the visit or recommend more comprehensive duct repair if needed.
