"These guys are awesome!!!! I woke up at 8am Sunday morning in JULY and my AC WAS OUT! I called three other companies and they either did not answer or I left a message. When I called Metro AC Dewayne answered and told me he could have someone out today, he also explained their emergency call service fee of $150.00 but I totally understood since it was Sunday morning. He took my information and told me a technician would call me within the hour. Larry, the technician called me about 15 min later and said he could be there by 1000am. Dewayne called me back about 45 min later to make sure Larry had called me and set up a time. Larry showed up at around 950. I showed him where the compressor was and that it had been running but the fan had not been spinning. He looked at everything and came in and explained he felt it was only the capacitor but it might be the motor. His plan was the replace capacitor and if that didn't work we would change out the motor. He replaced the capacitor, checked the pressures and temps coming out of AC, changed out my air filter (which he did not have to do) and was done by 1100!! Larry was nice and used shoe covers and was very professional! Metro air conditioning will be my new go to AC and heating repair and maintenance shop!!"

"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 !!!"

"Reached out and made contact Saturday evening. Jack called me back and we discussed my ac issues. Jack arrived promptly on time Sunday morning. Tested the ac system, installed the new part and recommended adding coolant. After adding coolant, he spent the time to check multiple rooms and gave us a fair price. Very satisfied!"

"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!!!!"

"My new air conditioner is truly a work of art! I obtained several proposals and while most of them were within a few percentage points of each other in terms of cost, I chose Efficient Home Solutions. There were several reasons. First, David took the time to show me the math about my CFM airflow problem. I have been short about 800 CFM all these years and it's probably why my other unit wore out after 12 years. I got a 5 ton Lennox unit and David explained the differences between it and a comparable Trane (which I had previously installed). I think having a local company with access to parts in the future was a great reason to pick Lennox. The unit is a beast. Secondly, David brought his installation manager who carefully inspected my attic space and location of new return ducts. No one else brought theirs. This made a big difference because there would be no question as to what would work space-wise or not. Third, David also answered all my questions professionally and even explained many details I hadn't thought of (nor did any other service provider). I really like my Nest control and this unit cools within 40 seconds, and after 2 minutes, it's freezing! The family room is facing the hot west sun and now we can't even tell it's hot outside. I highly recommend them!"

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.
