"I had my 27-year-old furnace and a/c replaced by them. The entire process was effortless. Joe and John were great to deal with. The 2 techs that came out were very friendly and efficient. They had the whole project done in less than a day. The clean-up and explanation of the new system met and exceeded my expectations. The new furnace works great and is much quieter than the old one. We only had a chance to run the air for one day, and it also worked very well. I would highly recommend Air Comfort Heating and Air Conditioning for furnace and a/c replacement"

"I recently had Prolific Mechanical install a new air conditioning system, and I couldn't be happier with the results. The young man who completed the installation was professional, courteous, and extremely knowledgeable. He took pride in his work, kept everything clean, and made sure the installation was done correctly from start to finish. The new system runs flawlessly and keeps the house comfortable even on the hottest days. I highly recommend Prolific Mechanical to anyone looking for quality workmanship and dependable HVAC service."
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.
