"Ray was friendly and very professional and you can tell immediately that he was very customer oriented. As far as prices go, he was more than fair compared to the other bids. As a matter of fact I expanded the scope of his work to include a new water heater too. All the equipment supplied was 100% new, still in the factory cartons and the installation work was TOP QUALITY. Ray not only sold me the job but he did the installation too. He and partner Ken, and their assistant (3 man crew total) worked very professionally and effectively. Needless to say I HIGHLY RECOMMEND THEM."

"He came when he said he would and installed two ceiling fans, replaced two light switches, repaired my basement door, and installed two plant holder brackets in the ceiling. He was a pleasure to work with and I was extremely pleased with his work. His prices were very reasonable for all the work he did. I would definitely recommend him to my friends and I would hire him again."

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.
