"My air conditioner stopped working tonight. I have a heart condition that requires a cool house. Juliano came out at 9:30pm and fixed the a/c. He was professional, courteous and personable. He explained what the problem was and how he was going to repair it. Most of all, he established trust with me, which is the most important quality that I look for when seeking out companies I want to hire. Romano HVAC gave me A++ service, and I am so grateful that my home is once again comfortably cool."

"The experience was fantastic! I never thought I'd say that about a furnace installation but the 2 servicemen Dmitry and his colleague made me feel very comfortable with all the proceedings. The last time I had to replace my central air system was different. The gentlemen doing the job were dismissive of my requests and ended up setting it up wrong having to return several times to finish. Nothing like that with RK Mechanical, super smooth sailing."

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.
