"At every levels, Reynold Company is outstanding. They really care, not only doing the job right but also doing it with a smile. The customer service as well as the technicians and even those who help you to get a loan (one year without interest) seem to love their job. Four things had to be done recently in my place: - new central heating/ air conditioning - new electrical pannel - new smoke detectors - new outside lightings that I can activate with my phone. PS. Fun fact: i learned today how to stop a screaming smoke alarm 😉."

"DO NOT EVEN THINK OF USING ANY OTHER COMPANY!! Alpines electricians and installers and management are the kindest, hard-working, most competent people you could ever want. My heat pump died the week before this terrible life endangering heat wave. I am very elderly with several severe physical disabilities and live in a metal manufactured house which heats up better than my oven! Alpines kind management, when informed that the dog and I were on the verge of fainting in the house which was over 105 degrees inside, sent their installation team over the next day, despite their schedule being backed up. Alpines price was competitive and the equipment is highly rated. I am pretty certain Alpine literally saved my life, because I had nowhere else to stay or live and the temp is expected to go to 114 degrees this weekend. The two electricians, the two installers, the supervisors, and the owner were all cheerful, pleasant, and worked no-stop from about 8:30 am to 8 pm to get the new heat pump up and working beautifully with no problems or hitches. I made sandwiches for lunch and they barely stopped working long enough to eat and to rest a little. The temperature inside the house was close to or at 100 degrees, but they kept working. All the Alpine employees were kind people whom I felt very lucky to have in my house. I could write forever, but I could never fully express my gratitude to Alpines wonderful employees,"

"They did a great job. That solved our problem for now but we are going to have to replace the whole system and we have talked to him about that. We were happy with the service. They were very friendly. They came out in a timely manner and explained everything. They were very thorough and it was everything that we expected. There was nothing that we were not happy with. We were looking at $4-5,000 for a new system and we were not able to do that right away so he was able to get the system working. They haven’t called us back regarding the new system but they were on time when they came. We would use them again."

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.
