"The results of the inspection were not exactly what I had hoped for but I now have a real understanding of the condition of my unit. Technician checked all wiring and connections and cleaned coils and checked compressor and added some refrigerant to the unit. AireServ did an outstanding job of helping me to better understand the condition of my A/C unit and to make a more timely evaluation on life expectancy of my unit. Recommended new system soon."

"The technician was very knowledgeable and fast. He fully insulated the primary condensate drain line in the attic. Repaired end termination of primary condensate drain pipe at rear foundation wall. Replace media filter on return duct. He actually alerted me to the fact that the downstairs unit had two filters. One inside and one under the house. This restricts the air flow. Removing one would create better air flow."

"Rob was gracious and professional, gave us a reasonable estimate and did the work on our duct system right on schedule. It has made a world of difference in our house's air quality. The only reason my review is 4 stars and not 5 is that this was before most people, including us, had been vaccinated for covid, so I asked Rob to wear a mask in our house, which I also did when he was inside. But he didn't wear one. Given that my husband has asthma and was thus high risk for complications if he were to catch Covid, this was a concern for me."

"We recently had a brand new HVAC system installed by Chisholm, and the entire experience was excellent. From the initial consultation to the final walkthrough, their team was professional, knowledgeable, and easy to work with. They took the time to evaluate our home and helped us choose a system that fits both our space and our budget. The installation crew arrived on time, worked efficiently, and made sure everything was cleaned up afterward. They also took the time to explain how the new system works and answered all our questions thoroughly. Since the install, the system has been running smoothly—quiet, efficient, and keeping our home consistently comfortable. We’ve already noticed an improvement in both temperature control and air quality. If you’re in need of HVAC work, I highly recommend Chisholm. They’re honest, skilled, and truly care about the quality of their work and customer satisfaction."

FAQs for air conditioning projects in Piedmont, SC

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
