"Mario was very professional and knowledgeable. He always answered any questions I had promptly and thoroughly. I had questions about sizing and seer rating for the unit and he let me know which one would best fit my situation. The crew always cleaned up after themselves and left the place like they came. They installed a new air handler and compressor in 1 day and came back to add an attic fan."

"Excellent! The team worked diligently for 5 days to install a central air system in our old house with Plaster Walls. It was NOT easy, yet they did a fantastic job. They were able to add all ducts to the first floor with out any "chases" or enclosures requiring to be build. And almost none of our first floor lines up with our second floor closets, but they figured it out. Great time and fantastic service. Make sure you get Brandon and Sean. The work their butts off, and ensure your house stays clean (they cleaned up everything after every day - not an easy feat). Cannot say how happy am I with their work!"

"First Alfano Mechanical Inc. came to my home, said they would do the job and called the office told them to get me on the schedule ASAP. Gave me a price per hour. Well he never called back to this day. Would not recommend them to no one. Job was to HARD for them. Also I had my AC on my worry free with PSEG and they made me take it off because they would not work on my unit in the tight spot that it was installed in my attic 11 years ago. SO WITH THAT BEING SAID: Celestial Air HVAC called when I first contacted Home Advisor and after not hearing back from Alfano(which I would not have hired because they didn t live up to anything he said while here), I called Celestial(and so glad I did) and they came the next day, said it was a hard job and a mess but nothing they couldn t handle. Anthony and Gus came the next day worked their butts off and I have my central air conditioning working right after 11 years. Great price and did over and above what was told to me in the beginning. I would recommend them to everyone and give them a 5 *****. We are very Happy People now. 👍👍😊😊"

"I was having a problem with my air conditioning. The thermostat was blank. I called Ray?s HVAC. They came over and identified the problem. Then they came back two days later and fixed it. Everything is working fine now. I would use them again and recommend them to people I know."

"I recently hired Kyle to service my central air conditioner. What a find!!!! I will absolutely hire him again. He is bright, personable and explains every step of his process. You can tell he is passionate about HVAC, and enjoys his work. He was able to quickly evaluate my system and get it back up and running. My system is old and really needs to be replace but Kyle was able to keep in running for another year... Highly recommend this company"

"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."

FAQs for air conditioning projects in East Hanover, 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.
