"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."

"Alpine installed my Trane heating and air conditioning system 18 years ago. At that time, I decided to purchase a service contract that would allow me to receive 2x a year cleaning and inspection. It was the best investment I could have made! Today their technician Troy came to conduct the preseason service on my air conditioner. My appointment was for 10am and Troy arrived promptly at 10am! During the course of the inspection, Troy discovered that the dual run capacitor was leaking oil. He showed me the part and suggested that it could be a problem down the road. Since the system is 18 years old, I wasn't surprised that there might be a worn part that would need to be replaced. Luckily, he had the part on hand and was able to do the repair right away. Because I had the service contract, I received a discount on the parts and labor which was greatly appreciated. I'm so glad that I called Alpine all those years ago. I highly recommend them for your heating and cooling needs!"

"I have used Speer Air for several years for HVAC preventive maintenance at my home. We recently expanded and they installed a package unit to take care of the expansion space. The work was good and they have been back for adjustments as necessary."

FAQs for air conditioning projects in Whippany, 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.
