"I first contacted Franklin Heating and Cooling in 2015 right after moving to this neighborhood and needed my thermostat replaced. Their pricing was great, the technician was nice and they got the job done right away. I then had low freonagain a few years later and cashed them again. I then started using them fairly regularly, twice a year for maintenance. I did call another company for service at one point and that proved to be a mistake, I reported that company to the BBB. I resumed using Franklin Heating and Cooling and have called them ever since for my HVAC needs. Caleb came out on a Sunday when my blower quit working, he was back first thing Monday to replace it (I was very grateful as I have a health condition). Most recently I decided to have my HVAC system replaced as a preventive measure as my furnace and AC unit were nearly 20 years old. Gary quoted me a great price and was able to get it scheduled within a weeks time. Jeremy and Ryan came out to do the installation and they were efficient, friendly and knowledgeable! Jeremy was a life- saver pointing out that we had ductwork that pulled in outside air, but it could be opened and closed as needed. This was in response to my indicating if had some issues even with the air on. Franklin Heating and Cooling are a caring bunch of professionals with great customer service skills and knowledge. Even Jackie and the gals in the office at nice and keep you informed! Jake too!! Look at their website, they have an A+ rating with the BBB!"

"Carl, the technician, came quickly and was thorough and professional in his work. He diagnosed the issue with our air conditioning and provided several payment options to see what worked best for us. He had to order parts for our air conditioning so he even offered to find window units for us to keep our house cool in the heat until it can be fixed!"

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.
