"Had a very difficult time finding a company that was respectful of the urgency/nature of my need to have the AC replaced given the 90 degree weather we were having. Had recently moved into a place and just found out it wasn't working. These guys came out to take a look and had the job done within 24 hours. Can't say much for the price, since I didn't have time to shop around, but at a time in need this couldn't be beat. I've had many home projects done over the past couple months, and It's refreshing to see someone take pride in their business and put their customers first."

"Robert contacted me within an hour of my request for a quote to set up an appointment for the next day. He was prompt (arrived early) and explained each thing he was doing and recommended various actions. The work he did breathed life into my old air conditioner and saved me the cost of having to replace it. The whole process was relatively painless. Robert was great!"

"Zack came in to give me quote as was the only guy who was not a sales person. Value for money wise his company is excellent. He installed Tempstar furnace and Media filter. We pulled the permit . The mechanical inspector came in and said whoever did this job did it professional. Particularly he liked how the media filter cabinet was installed. We couldn't get the CWire to the thermostat. He will be coming in this week to install it. Every electrical connection were clamped to the duct properly. He also put in new drain for the humidifier. Awesome guy. Normally I would wait for atleast 6 months to a year to leave a review. In this case, because of the exceptional installation and because of the comment that inspector made i am leaving 5 star review. Will update in future if any new issues crop up. I don't expect that to be case."

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.
