"This was the first time I hired a company to professionally clean my air ducts and dryer vents. Green Ductors worked well with all of my needs. They were professional and courteous. Igor took the time to explain the process from start to finish, what work was included for the price, and cleared up all of my questions. Igor called 24 hours before the start of the job to confirm. The technicians arrived 10 minutes before their scheduled time and explained the process once more! Ivan cleared up additional questions I had and completed a thorough check of my HVAC system, ducts, and vent. He took photos and explained their assessment of my system. They took their time and were mindful. They carefully moved furniture if they needed to and placed it back in its original position. Once the job was complete Ivan took photos and explained the work they completed. He sent me both sets of photos and shared some maintenance tips. I highly recommend Green Ductors!"

"We have two HVAC systems. Last spring I realized AC of the newer one did not work. Got a few estimates, everyone quoted the whole system for various reasons, except SOS. They pointed out the coil is compatible with current standard refrigerant so only need to replace the condenser. Took their proposal and the AC was fixed at a much lower cost. A month later, the AC of the older system also broke. Its coil was not compatible with new condenser so must be replaced as well. This time everyone quoted the whole system. SOS cost is much lower and we had a good experience with the previous job so the decision was a no brainer. The job was again done in time to our satisfaction. Admittedly both jobs had some minor issues. But they quickly sent technicians to fix them after we found out some time later so I would still recommend them without any reservations."

FAQs for air conditioning projects in Union, NJ

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.
