"There was a snag at the beginning when they realized, after beginning to dig, that the AC unit was on top of the oil tank and they'd have to call someone in to move it before digging could continue. That delayed things a few days, but thereafter they did a good job of digging and were very careful with our trees. They also took care not to ruin the lawn with the machinery. The new tank and heater were quickly put in the basement with no problems."

"I recently had the pleasure of working with Schede Plumbing and Heating, and they were a lifesaver when it came to fixing my central air issues. As a new homeowner, I’ve been faced with different challenges every day, but knowing who you can trust and ask for help makes all the difference. I was fortunate to be introduced to Schede Plumbing and Heating, and they exceeded my expectations. From the moment I called, they were quick to respond and provided a thorough analysis of the problem. They walked me through the options and suggested the most practical and affordable solution. I was serviced by two highly professional, polite, and skilled technicians, Paul and Randy, who were truly exceptional. Paul and Randy were efficient, trustworthy, and very customer-focused. They assured me that they wouldn’t leave until my issue was fixed and took the time to ensure no other issues were lurking. Their dedication to solving my problem and their attention to detail were impressive. I cannot recommend Schede Plumbing and Heating enough. They are a reliable and professional team who genuinely care about their customers and their work. Thank you, Paul and Randy, for your excellent service!"

FAQs for air conditioning projects in Old Greenwich, CT

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.
