"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."

"I reviewed several HVAC companies on Angies List and based on the number of reviews and content of the reviews I selected Brower Mechanical. The technicians arrived within the time window provided by the service dept. They called 15 minutes prior to arrival. I received a friendly greeting and handshake by both techs. They listened patiently while I provided a brief history of the unit, age and previous troubles/problems. They seemed appreciative of the information and went about their business. After completing the unit inspection and service they inspected the ducts and found four that, in their opinion, need replacing. I have been in the attic before and their inspection confirmed what I had seen earlier. We discussed a recurring problem I have had with the inducer vacuum nipple becoming plugged. The technician made some suggestions that could be implemented when and if I decide to replace a noisy inducer motor.
At this time I have made an appointment to have the four ducts replaced. While making this appointment I mentioned how satisfied I was with the technician that performed the inspection/service and was asked if I would like to have this technician assigned for future service visits. I, of course jumped at the idea. I find this action very refreshing and a legitimate sign/trait of a company that is focused on complete customer satisfaction.

"Attic was air gap sealed first, before added blown insulation. I immediately noticed that the interior stayed cooler during the day without a/c. Jesse the owner was great with estimating and evaluating need. No pressure, just honest info. He was on site during job documenting and sharing progress. Very impressed with service and quality."

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.
