"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 am very happy with the company that was sent out. Very professional, very efficient, excellent Choice. You know, I can't say enough about the air conditioning people who came. They did a very good job for me, and I appreciate Angie recommending them because I have never heard of them before, but I will be using them again, I assure you. So I thank you very much for that reference."

"I had an amazing experience with Ice City AC. From the first call, they were responsive, professional, and actually showed up on time (which is rare in Miami). They diagnosed the issue quickly and explained everything in a way that made sense—no upselling, no pressure. What really stood out was the honesty. Instead of trying to sell me a whole new system, they fixed the problem and saved me thousands. The work was clean, fast, and done right the first time. You can tell they know what they’re doing. My AC is blowing colder than ever, and the airflow in my house is way better now. If you’re looking for someone reliable, knowledgeable, and fair on pricing, Ice City AC is the real deal. I won’t call anyone else. Highly recommend."

"I had my complete 4ton air-conditioning unit replaced by East Coast AC & Refrigeration and I was extremely satisfied. There technicians did a beautiful installation and were very careful to work cleanly and had my new system cooling quickly. I have used East Coast for over 15 years because they have always treated me fair and they provide quick, professional work and use quality equipment while charging reasonable prices. I highly recommend East Coast AC & Refrigeration to family and friends as I have always been happy with their services."

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.
