"Rob was gracious and professional, gave us a reasonable estimate and did the work on our duct system right on schedule. It has made a world of difference in our house's air quality. The only reason my review is 4 stars and not 5 is that this was before most people, including us, had been vaccinated for covid, so I asked Rob to wear a mask in our house, which I also did when he was inside. But he didn't wear one. Given that my husband has asthma and was thus high risk for complications if he were to catch Covid, this was a concern for me."

Three Jay Heating & Air started the way most good businesses do – with a conversation between people who saw something that needed fixing.\nOur three founders come from different worlds. One spent years in cybersecurity, learning that systems fail when people cut corners and that the details you ignore are always the ones that come back to bite you. Another came out of logistics, where meeting a deadline isn’t a courtesy – it’s the job. The third spent a decade in the field, hands-on, diagnosing and repairing problems in homes just like yours. Between the three of us, we’ve learned that doing this right means being organized, being honest, showing up when we say we will, and never walking away from a job we’re not proud of.\nWe named the company Three Jay because it represents the three partners who put their names

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.
