"After getting quotes from a few companies for a new A/C systemI decided to go with Weathershield. Their price was very fair and they were very professional. Air conditioning works great. When the A/C went in an condo I own I called them. They did me a big favor and did the work up in Palm Beach county which is an area they do not usually service. Again, everything went perfectly. The A/C works great. The office manager Christine is a total sweetie and so helpful. Just called them to clean our dryer vent, so happy they provide that service, I wouldn't trust anyone else.... Thanks guys!

"I live in Century Village, Boca Raton in a unit that has wall A/C units not central air. My living room unit was leaking inside due to sludge build up. Cooling Experts was the only company that said they could help me. Their technician Paul was great very professional and cleaned up the area. This was a small job which most companies do not want to bother with. I am very happy and grateful to them."

"I came home from vacation to find my 15year old air conditioner was dead. Called East Coast just before 7am the next morning and by 9 Scott was here. After discussing options, I decided to replace and upgrade the whole system. He was able to get the old unit up and running that morning, while I waited for the new system to be installed. He sent a technician over at the end of the day to make sure It would make it through the night. The installation of the new unit went well from my perspective. The new unit was much larger than the old unit and the weather was not cooperative that day, but Joni, persevered and got the job done in a calm professional manner. His work was meticulous and he cleaned up after himself. At the end of his long (probably frustrating) day, he took the time to orient me to my new unit and thermostat. Scott was super, responding to my numerous questions and text messages throughout this process. After 35 years in Broward I have finally found an air conditioning service company that I can recommend."

"Lorenzo, the ARS technician sent to perform maintenance on our central air conditioning was thorough, professional and quickly spotted a part that would need to replaced that could fail at any moment. We have used ARS to both install and maintain our a/c units for 14 years and 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.
