"Decided to give MSD a call as I had another company over the house today to fix my AC and they were not able to repair it as they needed to order parts. Mehmet answered the phone and couldn't have been more professional/helpful. He spent 10 or so mins on the phone with me trying to understand the problem and give me advice. He unfortunately couldn't send some one out as he was super jammed with the current heat wave. I will not hesitate to call Mehmet again as he is a true professional and very knowledgeable."

"We were desperate to find someone to repair our central air conditioning unit. We were not able to move into the house and everyone that we called was not able to accommodate us because of the recent heat wave. All Weather was able to get a technician to us within 2 days. Nuri was amazing and showed my husband how everything worked and what repairs needed to be done. By the time he left, we had a cool house and were able to set up our movers. Thanks to Angie’s list, I found a reputable company that was reliable and efficient. We can rest easy! Thank you!!!"

"Now I feel safe turning on the unit after the ducts and the sealing was done and cleaning my air condition and my dryer and bath room filter and my condenser outside and putting a new cover for the vent outside of my dryer. After seeing the pictures it was worth the price."

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.
