"Maintenance visit was a win. Props to Cam, the technician that just spent two hours checking out and tuning up the two heads and one outdoor unit at my house. I did my best to simply stay out of his way, and when all was done, he gave me a brief report and kind but professional answers to two of my own questions. His service included taking care of a small issue with one of the heads. The service cost me less than I had thought. That's likely my own confusion, but it made me happy nonetheless!"

"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,"

"I had a heat pump installed so I could have AC in the summer as well as heat. Customer service was great from the office person to the installer. I thought the contract had enough detail to satisfy me but I did not find out until signing and paying deposit that electrical was not included. It would have been nice to know that up front. The installer was great and a bit of a perfectionist which was just fine with me. It led him to discovering that half my heating elements in existing furnace had been disconnected by previous owner and the reason was because that same owner had installed a transformer that didn't have enough volts to power all the elements. This was not easy to diagnose and I am grateful he persisted until he found it."

"At night it will be 72 inside. And inside will be 68 or less. I almost freeze. I DO NOT UNDERSTAND WHY."

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.
