"Great. Jerry Cobb came by to reprogram the thermostat for us. We were not able to figure out how to get it the way we wanted and Jerry took care of it for us. Cool Air replaced our entire HVAC system about 2 years ago. We were happy with the job and will be having them add a humidifier to the system soon."

"All Seasons Heating & Air is a friendly, fair, honest, ethical and professional company. I communicated with Brant and was very pleased with his patience to explain things to me and his honesty in not trying to sell me a new unit if I didn't need one. He blew out the pipes of my old unit and now everything has worked perfectly since then. I would highly recommend this company to anyone. They are better than the best!!!"

"I can't recommend Jade Heat and Air more. I struggled for years with a recurrent problem with my HVAC and dealt with several other service providers who couldn't seem to fix it. Jade fixed it and it stayed fixed for three years. Just had them out to fix a new problem and couldn't be happier with Cesar Aguilar."

"The ASSA MECHANICAL SERVICES LLC Team showed up promptly at the previously agreed, confirmed day and time. They immediately got to work with removing the old window mounted air conditioner unit which needed to be replaced and installed the new air conditioner. The whole process only took about one hour. A very professional and communicative team. The new air conditioner is working great. We’ll be requesting these guys again for any annual maintenance required for the window a.c. unit. Thank you ASSA MECHANICAL SERVICES LLC. Arthur"
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.
