Why Is My AC Not Cooling Properly in Knightdale?
The Problem
A homeowner in Knightdale noticed their air conditioning system was not cooling effectively.
What We Found
Mario found that the system was low on refrigerant and the unit was aging, which impacted its efficiency.
The Fix
Mario performed a comprehensive tune-up of the cooling system. He started by checking the thermostat and filter inside the home, then moved to the air handler in the crawl space to inspect the ductwork, refrigeration lines, and blower components. Outside, he inspected the outdoor unit, checked the compressor and fan amps, capacitor, and pressures, and cleaned the coil. He recommended the AHS upgrade program due to the unit's condition.
The Result
The homeowner decided to proceed with the recommended upgrade program to improve cooling efficiency.
Pro Tip
If your AC isn't cooling well, it might be low on refrigerant. This often indicates a leak or an aging system. Consider a professional assessment to avoid higher energy bills and potential system failure.

Why Is My AC Not Cooling Well in Knightdale?
The Problem
The homeowner noticed that their air conditioning system was not cooling effectively.
What We Found
Dexter found that the blower capacitors were weakened and the contactors were pitted.
The Fix
Dexter performed maintenance on two cooling systems. He washed and cleaned the coils, checked the capacitors and amps, and inspected the pressure and blower compartment. He identified the weakened blower capacitors and pitted contactors as the issues.
The Result
The air conditioning system was restored to optimal performance, ensuring effective cooling.
Pro Tip
If your AC isn't cooling well, weakened blower capacitors might be the cause. Listen for unusual noises or reduced airflow — these are early signs that capacitors need attention.

Thermostat Sensor Adjustment in Knightdale
The Problem
A Knightdale homeowner noticed that the air was blowing harder than usual from the vents and there was a slight delay when turning on the heat.
What We Found
Aaron found that there was an outdoor sensor fault on the thermostat.
The Fix
Aaron adjusted the thermostat settings by turning off the outdoor sensor setting in the installer configuration, which resolved the issue without needing to change the blower speed.
The Result
The heating system returned to normal operation, providing consistent airflow and timely heating.
Pro Tip
A delayed heating response often indicates an outdoor sensor issue. Before making adjustments, always check the installer configuration settings; disabling the outdoor sensor can quickly restore normal airflow without the need for more extensive repairs.

Outdoor AC Unit Empty on R-32 Refrigerant in Knightdale
What We Found
Mario found that the outdoor unit was empty on R-32 refrigerant and noted some conditions with the zoning system.
The Fix
Mario conducted a thorough maintenance of the cooling system. He began by checking the thermostats and filters, then inspected the air handler in the attic, including duct work, refrigeration lines, and wire connections. He cleaned the indoor coil and added cleaning tablets. Outside, he inspected the refrigeration lines and wire connections, checked the capacitor, and cleaned the coil.
The Result
The homeowner was informed of the system's condition and planned to address the refrigerant issue separately.
Pro Tip
If the outdoor unit is empty on R-32 refrigerant, it can indicate a leak or a failed component. Addressing these issues promptly can prevent costly repairs and maintain system efficiency; don’t wait to investigate further.

HVAC Maintenance reviews in Knightdale
Stephena Williams
“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!!!”

“Nick did a great job on my plumbing inspection.”
Amy Gray
“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.”

“I contracted this repair through my home warranty company AHS. A different company they initially had sent me to was going to charge me $2000 in out of pocket costs. Mario came from Element and re-diagnosed the problem and turns out I didn't need the part the other company wanted to replace. All in all Mario ended up saving me $1500. And on top of that, he was able to add 1 year of maintenance checkup within the amount I was paying. I will be going with Element from now on.”

Common HVAC Maintenance Issues in Knightdale
Deferred Maintenance Shortening System Lifespan
Many Knightdale homeowners skip annual maintenance, not realizing that unmaintained systems in climate zone 4A lose efficiency faster and are more likely to fail during peak summer when technicians are hardest to book.
Clogged Condensate Drains Causing Water Damage
Knightdale high humidity causes condensate drain lines to develop algae and clogs, leading to overflow and potential water damage in attics and ceilings — a problem we see frequently in Widewaters and Planters Walk homes.
Dirty Coils Reducing Cooling Capacity
Outdoor condenser coils in Knightdale accumulate pollen, cottonwood seeds, and construction dust from ongoing development, reducing cooling capacity by 10-20% if not cleaned annually.
Refrigerant Leaks Going Undetected
Slow refrigerant leaks in Knightdale aging systems go unnoticed for months, causing the system to work harder and ice up during peak cooling — a problem that routine maintenance catches early.

Frequently Asked Questions About HVAC Maintenance in Knightdale
Answered by our licensed technicians serving Knightdale
How often should Knightdale homes get HVAC maintenance?
We recommend twice-annual maintenance — once in spring for cooling and once in fall for heating. Knightdale higher pollen and construction dust levels mean filters should also be checked every 60-90 days rather than the standard 90-day interval.
What does an HVAC tune-up include in Knightdale?
Our Knightdale maintenance visits include refrigerant level checks, coil cleaning, condensate drain flushing, electrical connection tightening, thermostat calibration, and a full system performance test. We also inspect ductwork accessible from attic spaces, which is important in Knightdale two-story homes.
Is an HVAC maintenance plan worth it in Knightdale?
Yes. Our maintenance plans include priority scheduling, which is valuable during Knightdale peak cooling season when emergency wait times can reach 2-3 days. Plan members also receive 15% off repairs and extended diagnostic time to catch problems before they become failures.
Can maintenance really lower my Duke Energy bill?
Absolutely. A well-maintained system operates 10-15% more efficiently than a neglected one. For a Knightdale home averaging $148 per month, that translates to $15-22 in monthly savings — more than covering the cost of an annual maintenance plan.
