"Every thing went very well, two day install. They left downstairs air conditioning working over night for my comfort. Came back on time next day and finished up. They left garage floor and furnace area swept up. Men were very polite, quiet, knew what they were doing and wore booties when inside. Great people. New units are very efficient & have excellent warranties that transfer to new owner. On time and on budget. I have used AirCo for service on old unit for 22 years. Very happy with AirCo employees."

"I bought Advent's $49.95, 20 point air conditioning tune up because my thermostat display had been displaying BATTERY for awhile so I thought I had better have the tune up. The young lady who converses with customers is great. She is cheerful and happy. The two young men technicians were both very polite and helpful. They went above and beyond. A couple of vents were aligned better to give me maximum comfort. I was shown the filter and how to replace it and how often to replace it which is one of the many tasks that my deceased husband did so I knew nothing about the filter. After I made the appointment my unit stopped working. They found a part had burnt out. I paid the extra $167 for the part and when Advent's technicians left my air was working great. I will call Advent in the future any time I have a heat and air need."

"Charlie was wonderful in troubleshooting our issue. Although the issue wasn't able to be fixed straight away due to parts having to be ordered, he provided a temporary solution that was satisfactory until parts arrived. With temperatures below 30, he was a life savior. He also helped us on the same-day appointment on a Saturday. The best part of this experience, was Charlie also solved other issues that he had noticed with the moisture senors, which saved a potential problem with the AC come summer. Oh, he also helped improve our thermostats. All and all, very pleased with ARP Heating and Air, and would highly recommend."

FAQs for air conditioning projects in Lexington, OK

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.
