"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."

"I hired Manny from Angi. He and his co-worker Abel came to my home last week to verify that my A/C needed replacing. Manny took the time to inspect my unit and found several mistakes the installer made 10 years ago. I got a quote that was several hundred dollars less than another A/C company. I scheduled Manny to come out today to do the job. I could tell from the beginning that Manny and Abel knew what they were doing. While Manny was disconnecting the condenser, Abel was in the attic tearing out the old unit and began putting in the new coils and return air duct work. The job took 6 hours. When they were finished, I inspected the completed job. It was an amazing transformation. The A/C was cooling the house until it became frigid. With the new thermostat everything was easy to program and use. I would recommend Manny and Son Air Conditioning and Heating to any one whom need any type of work done on their heating or A/C. They are trustworthy and dependable."

"I contacted Team Enoch yesterday and they promised a tech to diagnose and fix the problem today. Chris G was dispatched and he quickly diagnosed the AC issue. He explained what had likely occurred and why the part needed to be replaced. I was pleased not only that he had the replacement part and could fix it immediately but also that it was under warranty! Chris was professional, personable and very knowledgeable. He got my AC working again at a fair price and took a load off my mind simultaneously. Thanks Chris snd Team Enoch!"

"He works on Sundays for no extra charge. When I did the request to be contacted by three companies, he called within 30 minutes and was at my house two hours later. Haven't heard from the other two. Very professional. The charge was $300 to unplug lines in air conditioning units (2) and install safety valves that will turn off A/C if leaks occur. I called because my house smelled like mothballs!"

"Comfort Land not only fixed the issues I was having with my air conditioning unit on one of the hottest days of the year, but they did it with amazing customer service from start to finish. From the moment I called the company, I could tell the person on the other end didnâ t just see me as a number. They took the time to listen to my issues to ensure I got the customer care that I needed. When the tech arrived, he was polite and even insisted on putting on shoe covers even though I told him he didnâ t have to. He quickly determined the issue and gave me all of my options. He was genuine and knowledgeable. I would highly recommend Comfort Land and will be calling them for all of my future HVAC needs!"

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.
