A homeowner in Durham noticed their AC was blowing warm air, making it difficult to keep the home comfortable during the summer heat.
Travis found that the contactor had high ohms and carbon buildup, which was affecting the AC's performance. The AC system underwent comprehensive maintenance. Travis inspected, cleaned, and tested all major components, including the air filter, condenser, evaporator coils, and refrigerant levels. The contactor was replaced to ensure efficient operation.
The AC unit was restored to full functionality, providing cool air efficiently throughout the home.
If your AC starts blowing warm air, it could be a sign of a failing contactor. Listen for unusual noises or observe if the unit struggles to start — these are early indicators of contactor issues.

A long-time Durham homeowner in the 27705 area noticed the panels on their outdoor cooling unit were left hanging (screwed loosely) after a cooling maintenance visit the previous June. There were no issues or breakdowns with the unit itself, just the panels that were not put back properly.
The condenser panels had not been double checked and resecured after the earlier maintenance work. Travis returned at no charge, inspected the condenser electrical panel, and fastened the panel cover securely so it was properly seated and protected against movement or exposure of the electrical components inside. He installed all available mounting screws and tightened them as needed so the panel stays in place during normal operation and servicing.
The condenser panel was left properly secured, with the electrical compartment in a safe and serviceable condition.

During a routine cooling maintenance visit at a home in the 27707 area of Durham, Travis found a capacitor that was out of spec. He replaced the capacitor during the same visit. He also thoroughly inspected, cleaned, and tested the system, checked all key components, and made necessary adjustments to ensure proper operation.
After testing, the unit was functioning efficiently.

May 2026
During a tune-up at a home in the 27703 area, Travis found that the contactor was still functioning but tested to only 1.6 ohms, indicating it is failing. He also noticed the drain line outside the existing crawl was cracked, missing its 90 degree fitting, and showed mud inside. Travis tested pressures, the capacitor, and amp draws, ensured the board was operating, tested the reversing valve, and looked at the blower motor. He recommended at least a flush of the drain line, and preferably cutting a 5ft section of PVC to attach to the current line under the home, with new pipe and a 90 fitting run outside.
Apart from the failing contactor and drain line, the rest of the system checked out and looked good.

It is now January of 2026, Service Technician Aaron has just completed the inspection and maintenance of my HVAC system. I continue to endorse the proficiency and professionalism of this company and their technicians. My equipment continues to work beautifully. I continue to endorse all of the applicable comments below. This is a company I can recommend without reservation. ——- Element Service Group has been a very professional company to work with. Aaron arrived on time he identified himself upon arrival, was wearing a shirt with Element Service Group name and as usual was driving a well branded truck in excellent repair. Aaron performed my spring inspection and maintenance and provided a detailed assessment of suggested upgrades I could share with my son. Once all work was completed he gave me an update on my system and work performed. All conversations were articulate and polite. My receipt was emailed to me in a timely fashion. Once again I can highly recommend Element Service Group. One side note when this company first began working on my system it came with a lot of noise on start up. Due to these technicians proficiency my system now “purrs”. I am barely aware it is functioning. I am so grateful it maintains a comfortable environment in my home along with my nest thermostat that they helped me install. Once again, if you are looking for a reliable and professional company call Element Service Group. Disclaimer: I have no affiliation with the company, owners or employees. I am just a satisfied customer.

Read articleDurham's diverse housing stock ranges from historic homes to modern builds, each requiring different HVAC approaches and solutions.
The Bull City's hot, humid summers with temperatures often exceeding 90°F demand reliable AC systems with proper maintenance schedules.
Many older Durham homes have ductwork that wasn't designed for central AC, requiring creative solutions and expert retrofitting.
Durham's tree-lined neighborhoods provide shade but also shed debris that can clog outdoor AC units, requiring regular cleaning and maintenance.
Durham's mixed-humid climate creates condensate drainage issues, mold growth on evaporator coils, and elevated indoor humidity that regular maintenance specifically addresses.
Durham's pre-1990 homes with gas furnaces need annual combustion analysis and heat exchanger inspection, as aging equipment poses increasing carbon monoxide risks.
Durham's older homes have ductwork that degrades with each passing year. Maintenance visits track this decline and recommend repair or replacement before energy waste becomes severe.
Some Durham homeowners have had partial system replacements that created indoor/outdoor unit mismatches. Maintenance evaluations identify these mismatches and their impact on efficiency and reliability.

Answered by our licensed technicians serving Durham.
For Durham's mixed-humid climate, the most critical maintenance tasks are condensate drain cleaning (prevents water damage and mold), coil cleaning (maintains dehumidification capacity), and refrigerant level checks (ensures proper humidity removal). These three items address Durham's biggest HVAC challenge: humidity control.
Yes. We adjust our maintenance approach based on your Durham home's age and system type. Older homes in Hope Valley or Forest Hills with gas furnaces get safety-focused maintenance including combustion analysis. Newer suburban homes get efficiency-focused tune-ups with emphasis on heat pump performance.
Durham's heavy pollen seasons (especially March-May) can clog outdoor coils and filters rapidly. We recommend scheduling spring maintenance in early April to clean pollen from coils before summer, and changing filters monthly during pollen season rather than the typical 90-day interval.
For Durham homes, maintenance plans pay for themselves by preventing the humidity-related failures and breakdowns that are common in our climate. Priority scheduling is especially valuable during peak summer when standard service calls may have 2-3 day waits. Our plans also include discounts on any repairs discovered during maintenance.
