"Troy did an amazing job! We had him do a deck repair for us last year that was done very professionally so this year we had him do some deck repairs at our son's house. Again, more amazing solid work! This year, we've had him do some shed repairs, fix a few door issues, replace some hinges, some bathroom remodeling and some general handyman repairs around our house and we are completely satisfied with the work. We highly recommend Troy!!"

"Larry from Fitch was very courteous and punctual. He was straight forward that he was more of an HVAC repair person than that of a hybrid water heater repair expert. He called Bradford White technical support and tried to trouble shoot the error codes that popped up. With tech support he was able to reset the water heater so that the error codes did not appear. He acknowledged that he was not sure if the problem was correctly addressed and cautioned that it might recur. Since this took a bit of time to trouble shoot, the labor cost proved quite substantial. Although I have no complaints with Fitch or Larry, I might have to look for someone more experienced with hybrid water heaters if the problems/error codes were to recur."

"Excellent customer service. Bob called shortly after my request for a quote. He asked a fair price and was able to take care of my job the following day. He completed the work quickly and correctly. I would call him again for any other handy man jobs I had. He showed up when he said he would. Good experience."
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.
