"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."

"I was in desperate need of an AC unit repair and Kyle came to the rescue. Iâ ve owned my home since 2019 and have been looking for and honest and reliable AC technician. Iâ ve used a couple of other technicians but Kyle will be my go to moving forward. He kept me informed of everything he was doing and educated me on how my unit should be running. He even gave me info for what filters I should be purchasing to help my unit run efficiently. He gave me several options with regards to repairs and I went with the higher priced option because it was so reasonable and I didnâ t want to cut corners. I will be scheduling my routine maintenance with him for the summer and winter. Iâ m so happy I finally found an AC technician I can rely on. I highly recommend him."

"I had my HVAC replaced in my condo during the summer of 2018. I had just moved and had painters working when it malfunctioned. There turned out to be a leak and I decided to purchase a new system after hearing about previous problems with the unit. I had used Valairco for annual checkups and was happy with the company. I ordered the new system requesting it be done as soon as possible because of the situation. They immediately ordered the new system and installed it as soon as it was shipped to them. Lou did a great job and I’m happy with my purchase and guarantee."

"I have an older AC system that wasn’t working efficiently. It was cooling but not very much or venting well. The guys came in a timely manner and serviced the unit. I was concerned about having to get a new unit, but it just needed servicing. The guys were great and explained everything to me. I would definitely recommend them and use them again"

FAQs for air conditioning projects in Mountainside, 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.
