"We had a central air conditioning unit replaced. Chris was quick to respond via text message. He arrived exactly at the time he said he would, completed the job in less time than expected, ensured the unit was functioning properly before he left. He additionally offered tips and tricks for yearly maintenance on the unit. He was friendly, courteous, and reliable. We would definitely recommend him in the future."

"This was the best service with 2 highly qualified gentlemen. They were both knowlegable and friendly. They arrived 20 minutes after the initial call which was at the end of their day. They could have gone home for the day like the bigger companies did but instead they stopped on their way home and serviced my central air condition system in the middle of a heat wave. Unlike the other companies that I called who couldn't respond for 3 to 5 days even after I explained I had an infant to keep cool. If you're looking for a reliable company MTS is where you should shop"

"My AC wasn't blowing cold air. Bernard & his assistant came within a couple hours, diagnosed the problem and had my AC back to normal by the middle of the afternoon. It's been working great since then. Both men were very polite, patient and helpful. Would definitely use them again."

"My electrician from Cotti-Johnson HVAC was a master electrician. If you get him, you are getting the best. I went with the most expensive work package of the 3 that were presented. First off, it was pricey. I knew that going in. I want Cotti-Johnson to understand that I am serious about a working relationship with them. I feel I have done that with their electrical department. Now, if I need their plumbing or HVAC service, our relationship can build off the first experience."

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.
