"Robby and his crew were amazing. We are remodeling a 1930's bungalow and it needed a complete new HVAC system, ductwork and all. I talked with at least 5 HVAC companies and found Robby to be the most honest and helpful of all of them. I couldn't be more pleased and would not hesitate to recommend R Wiley to anyone that needs service or replacement."

"I had trouble with the AC about a month after they did an annual service and replaced the capacitor. The system locked up and they came out and I watched as they pulled an obviously old, worn, and burnt, electrical part out next. They replaced that part for the cost of the part and waived the labor as it was so close to the last service. The system is old and they were finding parts that were reaching the end of their life and replacing rather than trying to sell me a whole new system but let me know they would be there if I decided I needed a new system. Fast service, pleasant and knowledgeable personnel."

"We called "Good to Go" for an estimate to replace our old and reported to be failed air conditioning system. Mr. Kaurin visited us and inspected the unit He reported that the air compressor's low voltage source was disconnected and that the capacitor was bad. He replaced and repaired the unit and had it operating within 1/2 hour of his visit. We will have "Good to Go" replace both our furnace and A/C system when either system becomes un-repairable. We have his quote for a Rudd system and will be ordering from this honest professional, Matt Kaurin. George J Randolph, Roscoe Road, Newnan, GA"

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.
