Why Is My AC Making Strange Noises in Cary?
The Problem
A homeowner in Cary noticed their AC unit was making unusual noises during operation.
What We Found
Dexter and Jeorell found that both the capacitor was weak and the blower wheel needed cleaning.
The Fix
They performed a thorough maintenance check, cleaning the coil and blower wheel, and tested the capacitor and contactor. They also checked the refrigerant levels and overall system performance. They suggested adding a UV element to control unwanted growth and a pan treatment to assist in clearing the drain pipe.
The Result
The AC unit was restored to optimal performance, eliminating the strange noises.
Pro Tip
A weak capacitor can cause your AC to make unusual noises. If you hear strange sounds, it might be time to have your system checked before it leads to more significant issues.

Why Is My AC Not Cooling Efficiently in Cary?
The Problem
The homeowner noticed that their AC units were not cooling efficiently.
What We Found
Jeorell found that the systems required a thorough inspection and maintenance, including checking the voltage, blower amps, and capacitors.
The Fix
Jeorell performed a comprehensive cooling tune-up on two systems. He inspected the duct work, refrigeration lines, and blower wheel. In the attic, he checked the indoor coil and blower cleanliness. He washed the outdoor coil and checked the compressor and fan amps. After discussing with the homeowner, he replaced the capacitor and contactor.
The Result
Both systems were cooling properly after the maintenance.
Pro Tip
If your AC isn't cooling efficiently, it might be time to clean the outdoor coil. A dirty coil can reduce efficiency and increase energy costs. Regular cleaning can help maintain optimal performance.

Why Is My AC Making Unusual Noises in Cary?
The Problem
A homeowner in Cary noticed their AC unit was making unusual noises during operation.
What We Found
Aaron found that the unusual noises were due to a lack of lubrication in the AC's moving parts, which is common when regular maintenance is skipped.
The Fix
Aaron performed a comprehensive AHS tune-up on the cooling system. He lubricated all moving parts, checked refrigerant levels, and ensured the system was operating efficiently. This tune-up was covered under the homeowner's plan, ensuring no additional costs for refrigerant-related repairs.
The Result
The AC unit operated quietly and efficiently after the tune-up, providing the homeowner with peace of mind.
Pro Tip
Unusual noises from your AC often indicate a need for lubrication. Schedule regular tune-ups to keep your system running smoothly and prevent costly repairs.

“Today we had the pleasure of meeting Chris with Element Service. An old hand-crank pump that has been in our yard for 62 years ruptured when someone actually tried to crank the pump to see if it worked. Our backyard was flooded and we were beside ourselves when we learned our home maintenance plan wouldn't cover the repair. But then we remembered that the Element HVAC team had been out to service our unit and had told us they also had a plumbing division. We called this morning and they made a way out of no way to get someone here today. At 2:38PM we got the call from Chris and he was on the way! He was GREAT! Not only did he cap the line--having to bust through concrete to do so--he also kept us laughing! We were so upset when he got here, but were laughing and having a good ole time when he was done. He was determined not to leave until he fixed the problem and got our water back on. As the cliché goes, that was service with a smile! Thanks so much Chris, and thanks to the HVAC team for letting us know they also provided plumbing service. And I would be remiss if I did not mention the cost! We were floored as we were expecting an astronomical bill--especially having to get through concrete! Needless to say we were greatly surprised!!! Thanks again, Chris! Cameron has a good one!!!”

“I’d like to extend a big thank you to Nick and the new plumbing department at Element Service Group. They’ve consistently done an excellent job maintaining my HVAC system, so when I learned they had started a plumbing department, I expected the same level of professionalism—and they delivered. They provided a courtesy plumbing inspection and thoroughly checked my entire home. I’m happy to say everything received a big check mark. The only recommendations were simple maintenance items to help keep everything in great condition and give me peace of mind about my plumbing. I highly recommend their team. I’ve lived in this home for 40 years and have had many different tradesmen work here, but today I realized I’ve finally found the right company.”

Airflow Challenges
Cary's suburban growth and tree canopy create unique airflow challenges, requiring properly sized HVAC systems to efficiently cool multi-story homes.
Humid Subtropical Climate
The area's humid subtropical climate with 90°F+ summer temperatures demands high-efficiency AC systems to manage energy costs and maintain comfort.
Aging Systems
Many Cary neighborhoods built in the 1990s-2000s have aging HVAC systems nearing replacement age, making preventive maintenance critical.
HOA Requirements
Local HOA regulations in Cary's planned communities often require specific equipment placement and noise level compliance for outdoor AC units.
Common HVAC Maintenance Issues in Cary
Aging Systems Need More Frequent Attention
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.
R-22 System Monitoring
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.
Filter Neglect in Tech-Busy Households
Cary's tech-corridor professionals often neglect regular filter changes, leading to restricted airflow, frozen coils, and premature compressor failure.
Ductwork Degradation Over Time
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.

Frequently Asked Questions About HVAC Maintenance in Cary
Answered by our licensed technicians serving Cary
My Cary home's HVAC is 20 years old—is maintenance still worth it?
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.
How do I know if my Cary HVAC system needs more than maintenance?
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.
What maintenance plan do you recommend for Cary homeowners?
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.
Do you check ductwork during Cary HVAC maintenance?
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.
