"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."

"Saturday afternoon and I realized my home was not cool. The thermostat was 83 and climbing. I was able to contact A-Anderson HVAC and electrical. They were at my house in less than an hour and less than an hour later my AC was cooling. Dylan stayed long enough to check the air temperature coming out of the vents. He was very friendly, thorough, knowledgeable . Everyone from phone to personal service was great. The price was also in my expected range. I highly recommend this company."

"My air conditioning condenser went out the fan stoped blowing on the hottest night of the year. He contacted me right away the next morning at 9 am and we made an appointment for that afternoon a Saturday that was forecast to be over 100 degrees . I was expecting to be told I needed to buy a whole new condenser unit and I wouldn t have air conditioning until Monday. Crossing my fingers that it wouldn t cost more than my credit card limit. He came and gave me a fair quote for a new unit and also quoted me for a repair he said should keep the unit running for three or four more years. He showed me the most cost effective solution to my problem. He explained the pros and cons to each scenario. What I thought was going to be a financial crisis in the thousands of dollars and a weekend of sweaty misery. Ended up in the hundreds and I m sitting in my living room enjoying the air conditioning all before 3pm. Best service I ve ever had !!!"

"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!!!!"

"If you are looking for new A/C systems - look no further. The team at Enoch is the best I’ve ever seen. I have never seen a large HVAC vendor that the owner of the company came out to do the original walk through. Miles (the owner) is professional and extremely knowledgeable. Not only was his bid incredibly competitive - he also notice that we wanted to have two crews to handle the large home project we had done for new A/C and furnace solutions. The work was done all in one day and they spend extra time cleaning up after all the work was done. Then the next day Miles called me back to make sure everything was done to our satisfaction. If you are getting bids for new AC systems - you must have Enoch come out and give you a bid. I rank them a 10 out of 10. The best I’ve ever seen."

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.
