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.

Loud Blower Fan in Knightdale HVAC System
The Problem
The homeowner noticed that the blower fan was unusually loud.
What We Found
Travis found that the blower fan was a bit loud due to a buildup of debris on the blower wheel, which is common in older units.
The Fix
Travis inspected the HVAC system and confirmed that, despite the noise, the unit was functioning properly for both heating and cooling. He recommended a cleaning of the blower wheel to reduce the noise, although this service was not covered by the homeowner's plan.
The Result
The HVAC system continued to operate effectively, providing both heat and air conditioning as needed.
Pro Tip
If the blower fan is unusually loud, it could be due to debris on the blower wheel. Clean it regularly to prevent further wear and tear — a noisy fan can lead to more serious (and expensive) issues down the line.

Efficient HVAC Blower Cleaning in Knightdale
The Problem
The homeowner noticed their HVAC system was not performing efficiently and was noisier than usual.
What We Found
Aaron found that the blower wheel was covered in dust and debris, causing restricted airflow and imbalance.
The Fix
Aaron thoroughly cleaned the HVAC blower, removing all dust and debris from the blower blades and motor. This cleaning restored efficient airflow and reduced the strain on the blower motor, which in turn improved the system's performance and reduced noise levels.
The Result
The HVAC system now operates more efficiently and quietly, providing better air quality and lower energy costs for the homeowner.
Pro Tip
A dusty blower wheel can lead to noise and inefficiency. Regularly clean the blower blades to prevent airflow restrictions and ensure your HVAC system runs quietly and efficiently, saving energy costs in the long run.

“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.”
Verified Google ReviewCommon 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.
