"We hired Romano's to repair a central air conditioner that was not producing cold air. Juliano is an exceptional technician. He arrived on time, diagnosed the situation quickly, had the necessary part available in his truck and had us cooling the house in a matter of minutes. He also fully explained what was done, and stayed long enough to ensure that the air produced by the unit was the right temperature. We highly recommend Romano's for air conditioning repair."

"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."

"Just thought I would drop you a line, saying that I appreciate your teamâ s work the other day. I found a leak and it was coming from the AC unit. I called in the morning, they sent a service tech out that same morning, he showed on the time that I was scheduled, fixed the issue and we were good to go. Great job."

"Our technician Jet came out and after diagnosing the problem he discussed what he found with us and also suggested some preventive maintenance procedures to save us from some future maintenance. After agreeing on work to be done Jet took care of the necessary repairs and now the air conditioning is working perfectly. We were very pleased with the professional and honest work performed and will definitely be calling Huft Heating and Air Conditioning for any future repairs."

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.
