"We scheduled a 4 pm appointment. By 4:45, no one showed up or called to confirm their whereabouts. I had to call Metro Air and ask what was going on. The secretary said she will dispatch a technician to my house. The technician did not arrive until 5:30. He was kind and was able to fix the capacitor, which was causing the issue. About a week later, their office followed up. I told the lady that the a/c was on, but now there was another sound coming from the system. The secretary indicated that the technician would call me that day to discuss and set up a follow up visit to address the issue. No one ever called."

"Everything went great. They were professional. They sent a video introducing who would be doing the work. They assessed the problems, gave me a fair quote & I had the whole HVAC system replaced! Excellent job. Tomorrow the owner will come and explain everything to me again & I will download the thermostat app and complete the transaction $$"

"Jack at A-Anderson came out on very short notice on a Sunday night to look at our AC unit. He spent 1.5 hours testing and evaluating the unit to determine the problem. He replaced a faulty capacitor and added some Puron at a very reasonable price. He closed up the unit and cranked it up - we've been cool ever since. I would highly recommend Jack and A-Anderson AC to anyone. Prompt, friendly and quality AC repair companies are hard to find and I'm glad Home Advisor found Jack for me."

"I recently had the pleasure of working with Young and Son for an air conditioning repair project, and I couldn't be more pleased with the service I received. I was referred to the owner, who now operates out of Texas. From the moment he arrived, it was clear that professionalism was a top priority. He communicated effectively throughout the entire process, ensuring that I understood what needed to be done and the costs involved. The pricing was very reasonable, especially given the high quality of Overall, I highly recommend Young and Son for any HVAC needs. So happy to have found you!!!!"

"Technician came out in the evening to diagnose why compressor was not running. He was very efficient in determining the problem was the contactor, which is about a $25 part. Replaced the part in about 30 minutes and decided to check the freon to see if it was okay. Everything checked out and it took about 10 minutes to write up the invoice. In total, it took about an hour. The bill was $359.00. I asked why so high when it only took an hour and the part was about $25. I also asked why didn't they charge me for the time spent on the repair and the part. I was told that's just what they charge for this job. I absolutely will not use this company again."

We pride ourselves on offering Cost-Effective and Sustainable Solutions.

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.
