"Mr. Duct answered my call for service and was able to schedule within a few days at a time that was most convenient for my schedule. They were very open about the scope of the job and the pricing and I was more than satisfied with the quote for the work. The service technician, Mario, did an excellent job. He worked especially **** ** the second floor ducts which were just filled with construction dust and dirt! He arrived on time, was very careful as he worked, and was not the least bit fazed by the condition of those ducts! He just got to work and made them shine! I appreciated that he took pictures and shared the before and after so I could see what needed to be done. He also cleaned out the dryer vent and the outside air conditioning condensers - all with a smile and a wonderful attitude. Mario clearly had a strong work ethic and kept me informed about the progress as he moved floor to floor. I will be scheduling a cleaning next year, likely in September, and will request that Mario return to do the job. The house just feels and smells so much cleaner and fresh! Thank you Mr. Duct (and especially Mario)!"

"Angel and Tyler worked their butts off to help us with our air conditioning. They unfortunately had to do way more work than expected, however they were at our house late and always stayed in communication on what was going on. They did a great job and were very detailed and thorough with all testing making sure that the job was done right and there were no issues. We had a great experience!"

You should try him first before calling other companies. You would be very pleased if you did that. He came on time. He was very professional 100%. I lined up annual project for him to tune up and inspect our HVAC to keep it good running condition."

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.
