"I know this review is a little late, but here goes! We hired Jimmy to replace our subfloor in part of our conventional home. Jimmy was awesome from day 1! He came on time to do our initial quote and threw around some possible ideas, tried them and tried to problem solve to find the best possible fix for our floor issue. He was here for over an hour, crawling under the house, checking framing, measuring and explaining what he recommended; which was nice considering we had 3 other repair guys give us a quote and only stayed for 10 minutes. Jimmy went above and beyond to make sure that the floor was completely sound, and also made sure to choose good quality materials such as the plywood. He chose to buy from one store over another because they had better conditioned wood. We can't say enough good things about Jimmy, he was on time everyday, explained his process, and even went out of the way to repair our threshold and included it in his fee. He has an honest work ethic, reasonable prices, extremely hard working and just an all around good positive guy. We will DEFINITELY use him again in the future!! Thank you for all of your help Jimmy!"

"He did a great job!"
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.
