"The work consisted of replacement of gas furnace as well as air conditioning unit from early 1990's. SOS's price quote was competitive with two other quotes. I elected SOS specifically due their responsiveness, cooperation, proximity, and rating on Angi's List: 1) owner (Rob S.) came out immediately on a Saturday a couple hours after my call to review job and provided the price quotation within a couple of days, 2) quoted work with different AC manufacturers based on my preferences - did not try to push other units, 3) scheduled work per my calendar request. The crew. lead by Michael W., was very hard working, professional, and dedicated. I was also very impressed that crew performed a separate pre-inspection a week before the installation to familiarize themselves with the scope and work out a few details. Job was completed according to the schedule and quoted price!!! In summary, I'm very happy with the quality of work as well as my decision to select SOS. I highly recommend selecting SOS."

"Peter and his crew were great. We replaced our steam heat and window AC units with their LG high-efficiency dual zone (heat and AC) unit. The air is great. The system adds moisture so it is not the DRY air that is typical of electric units. They showed up on time for the work each day. They were ALL very polite, clean, well spoken and knowledgeable. It is rare to be able to say that about ALL of the workers. We have an OLD home, and they worked around every obstacle that was in their way without tearing apart walls, floors, and ceilings like other companies admitted they would indeed have to do. Peter will take the time to explain anything you have questions about, so do not hesitate to ask. My wife and I had many questions and felt much better after asking them. They work with you and have the mentality that it is YOUR house so it should make YOU happy. They are not done after they get paid, they work with you to make sure everything is to your liking even after it is up and running. Oh, and it will NOT cost you more than the competition. In fact, it is just the opposite. So glad we went with them!"

FAQs for air conditioning projects in Millburn, 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.
