"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!

"The absolute best HVAC contractor you will find! Honest, Trustworthy, Professional, Accessible, and fair pricing! There is no comparison. I unfortunately have used other companies before finding RCI and there were far pricier and unreliable! I am thrilled to have found RCI and will recommend them to everyone! I have already recommended them to friends who needed a new AC, RCI's pricing was the best of 3 estimates, and my friends were thrilled with their professional service! Look no further, call RCI confidently for all your HVAC needs!!! Thank you Mike and your RCI staff!"

"⭐⭐⭐⭐⭐ We had an exceptional experience with this Skyline HVAC. They completed a major HVAC project in our older home, including duct repairs, the installation of two new A/C units, and new air vents, and the quality of their work was outstanding. This was not an easy job. They carefully worked through the crawl space to avoid opening walls whenever possible, planned every step thoughtfully, and paid attention to details that many contractors might overlook. They thoroughly cleaned the installation areas before placing the new units, ensured everything was brought up to code, and properly insulated and routed all the condensate drain lines from end to end. What impressed us most was their craftsmanship, professionalism, and commitment to doing the job the right way rather than the easy way. Every aspect of the installation was meticulous, and the final result exceeded our expectations. Whether you need a small repair or a complete HVAC replacement, I recommend this team full stop."
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.
