"Our A/C was out for over a week while we dealt with Home Warranty and other A/C Companies. We found Jeff on Home Advisors with Great reviews. We called and got ahold of Jeff. He came out to the house within the hour. Checked our existing unit that had failed. Recommended replacing our split A/C & Heating Unit. Keep in mind that our Home Warranty kept us waiting while temperatures outside were exceeding 100 degrees. We agreed to work with Jeff and his team. They were out the very next morning and installed our new Unit. Truly a blessing to have connected with Advanced Comfort Air Solutions. Jeff and his team were very professional, treated us and our home like family. I definitely recommend Advanced Comfort Air Solutions, for any of your A/C or Heating needs. The night before the new installation, our temperature inside the house was 95 degrees! Thank you Jeff for responding so quickly and providing comfort for our family. Advanced Comfort Air Solutions answered a phone call, saw our situation, responded and had our new Unit installed and cooling our home within 24 Hours. Job well done!! Thank you so much! This was truly a connection meant to be. Thank you so much Jeff, Dave, Mike and Mike! Exceptional and outstanding service."

"Mark came out the day after I submitted an online request for an appointment. He was punctual and professional and explained everything he was doing. He had the part he needed in his truck, and he had my furnace up and running in no time. While he was here, he took a look at my air conditioner and informed me that it looked fine and was ready for the summer. These guys are honest and professional -- I was very happy with my experience."

"The experience was fantastic! I never thought I'd say that about a furnace installation but the 2 servicemen Dmitry and his colleague made me feel very comfortable with all the proceedings. The last time I had to replace my central air system was different. The gentlemen doing the job were dismissive of my requests and ended up setting it up wrong having to return several times to finish. Nothing like that with RK Mechanical, super smooth sailing."

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.
