"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."

"This Guy is a real pro at what he does! I don't have enough words to express my appreciation with the Job he did in my attic with the air conditioning ducts. Besides being an excellent air conditioning pro he is pleasant and honest. I had interviewed 3 other companies for the Job and I decided to go with him. The minute He went in the attic he asked me all the right questions. Questions to better replace the ducts in my two story condominium. since the air condition unit is in the first floor he needed to find the ducts on the walls in the second floor and figure out where they where. There was a duct that went to my kitchen that has never worked. He figured out that the duct came up the wall trough one of the closets. He opened a small hole on the sheet rock and fished out the duct and connected it with the other one in the attic .My home is actually cool for the first time since I moved in and I have and air condition kitchen."

"I had a terrible experience with a previous contractor who charged me $2,700 and didn’t even fix my AC. Luckily, Mr. David from Air Bear came out, located the issue immediately, and explained everything thoroughly. Air Bear is a very dependable and honest company. If you want to support a fantastic Veteran-owned business that does top-notch work, look no further. I cannot recommend them enough!"

"I was just getting home from work and I happen to noticed that my house was really hot, the thermostat was reading 85 degrees while set for cool, the blower was working but my air conditioning system would not come on. I stepped outside and walked over to the system and heard a buzzing noise but nothing was working so I went on to my app and requested for an air conditioning company and Young and son stopped by the same day. Julius was able to diagnose the problem I was having with my AC system and explain the buzzing noise, within a short period of time my air conditioning system was working and providing my home with cold air. Thank you!!!!! So much young and son, I am going recommend your services to all of my friends and relatives."

"We bought 3 AC/Heating units for our four-thousand square foot home in November of 2022. The owner—David—provided us with (1) the best personal feeling of expertise among five companies that I contacted and had come out and look, and (2) he provide us with a great rate on all three units—it was not the cheapest bid, but also not the most expensive—it was right in the middle of five separate bids we were provided. I do my homework, I ask numerous in-depth questions, and had David walk through our home more than twice. He answered every question, provided an expert analysis. I highly recommend Efficient Home Solutions (EMS). We have now been in our home with the three new units for 17 months and we have had “no” issues with any unit. We have perfect AC/Heat in all three zones of our home. We have bi-annual visits from EHS to check the systems and change the filters. In addition, they look nice on the outside of the home, and you can tell they were installed by a professional. David and his team are a joy to work with, and “Efficient” is a great name for their company."

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.
