"My A/C unit was blowing hot air out on Tuesday 4/15 and I called Dynamic Comfort who installed it that afternoon. On Wednesday 4/16 Will came out gave it a leak test and determined that I did in fact have a leak and he gave some refrigerant to last through the night which it did. On Thursday 4/17, Brandon came out and found the leak, but that was not the only problem, he stayed here for around 5 hours until he found the problem, which was a bad pipe that needed to be replaced. Brandon did a very through job in finding the problem and he wasn't going to leave until the problem was fixed. Dynamic Comfort has always provided me the most excellent service and this was another prime example. Kudos to them and their technicians Will and Brandon!!!!"

"Home Advisor recommended Will s allpro Plumbing/Air Conditioning. Spoke to James, I explained to him about how I was trying to do what was an easy job with my shower faucet cartridge replacement. Unfortunately the sleeve got stuck in the valve rendering myself from going any further. Frustated and being without water for a day .I decided to swallow my pride and ask for professional help. Don t get me wrong YouTube and HomeDepot are great guides but if they don t carry the tools to help you it can t go any further without possibly damaging the problem further . I was not willing to learn that lesson again. So I called and received several Plumbing company service but Will s Pro was the 2nd service to call me. What I liked was they were available to come out and they gave a free estimate allowing me to view options. I accepted their service and within the hour that I had called a Mr. Douglas Rivera plumber with Will s allpro was at my door. Douglas was very professional and friendly knowing my frustration;he offered me two options showing me how each option would possibly go. I chose the 1st option which he was recommending and crossed my fingers. Within 15 minutes he was done thanks to already having the new part there. Douglas was very understanding and explained thoroughly the out come of the options . I would like to thank Douglas and hope that he continues utilizing his professionalism to the highest he can go. I am very satisfied with this service from Will s allpro Plumbing/Air conditioning and would recommend them. San-D."

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.
