"After I posted my initial reviews, the owners of Air Temp Service Co. (Mario and Lori) reached out to me, and wanted to make it right. They are a family owned business, and proud of the work they do.We talked about the issues with our interactions with their company. After some additional research, I agree that the Nest Thermostat does need a common wire, and its beneficial that we had it installed. The other issues were due to the technician that was working with us at that time. That technician was removed from the company a few weeks after the work at my house was complete. The technician was responsible for the up charge on service, and pushing us to replace the CPU for our central AC (this should have been communicated as being the worst case scenario instead of the first step to fix the issue).The outside unit which was the main job I contracted Air Temp Service Co. for was installed cleanly and quickly. It was good work. They have also removed the technician who caused my family so much grief. I would say if you are a potential new customer they are worth giving a shot. They will take care of the job, and if you do have an issue they will make it right."

"Spoke to Damian Tuorto regarding the project to Install a Central Air Conditioning System and said that it had already been taken care of so asked if there were any other upcoming projects in mind and he said not for now so advised about the 600 categories and to download the app or visit the website if anything was needed. Closed the SR"

"I needed my AC fixed ASAP. Another company gave me the run around for 2 days straight. I decided to see other companies in the area and i can’t across celestial air HVAC. They gave me a same day appointment, came on time, fixed the issue within minutes, kept me updated the entire time, and now my tenants are happy again. Thank you!"

"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"

"My wife and I appreciated the time Wayne took explaining what needed to be done and answered all of our questions prior to and during the installation. He and his crew did an excellent job installing the 2 high efficiency HVAC systems. Both systems are running well. I thank Wayne for his ongoing dialogue during the installation which gave us confidence in the quality of his workmanship. Even though the systems installed were an upgrade the cost was less than all the other installers that gave us price quotes for the project."

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.
