"So far so good. They were informative, professional, and we have cool air again on a 105-degree day. I would have liked to pay less, but LaVerne and Son seemed to be the most reasonable for the equipment and level of service they provided. They were pleasant to work with."

"SoCal Climate Control is a trustworthy and excellent pro for Air Conditioning. Ryan walked me through the AC system at my home patiently and in a detailed manner. He also provided all solutions for me to choose. The service team came in the following week to perform a full clean of the system. They were very hard-working and could meet all my requests for the job."

"The technician called when he was on his way. On that particular morning the smoke alarms decided to start conversing with each other. Unable to reach one of the smoke detectors I asked the technician if he had a tall ladder pretty much as soon as I opened the door. He did. He offered to replace the battery but that didn't work on another smoke detector so I just asked him to take it out. Favor number 1. While he and the other technician were working one one of the four bedrooms I asked if he could measure and cut a chair rail I attempted to put up in my daughters room and gave up on. Favor number 2. We had the chair rail and I figured he would just cut it and leave it to me to put up, which a would have been fine. He measured, cut and installed the chair rail and it matches the baseboards. It looks great. Better than I could have done. Once the baseboards were done, they caulked and sanded them. We've had other baseboards installed in the main living areas of the house and the installation of those didn't quite measure up. They weren't as thorough when cleaning up and left chucks of baseboards on the floor with some other debris, but with the extra favors they did, I'm completely satisfied. Hopefully we won't need more baseboards In the future, but if we did, I know who to call.

"Our part of the country is having a BIG heat wave. There was a high demand for air conditioning servicing. Arron and his assistant, Joe, came and did the needed repairs quickly and left no debris behind. I was very pleased with their work and professionalism."
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.
