"Wonderful. I called PANDA and they came out in 2 days and did the work in 1. These brothers treat you right and do the right job! They did my central heat repairs 2 1/2 years ago and they were the first ones I called again when the air went and I was right to do so. Thank you Serge and Mark!"

"The Appliance Guy (Justin) was exactly what we needed. Straight shooting, to the point, knowledgeable and professional. Repaired our 1930s antique Magic Chef that others quoted us insane amounts to get up and running. Justin came in, did a thorough cleaning, located the issue, repaired the pilot light system and got her up and running at a fair price. So pleased with the outcome of his work. Will 100% use again for future appliance needs."

"We recently had our home HVAC system installed by Fanoli and we couldn’t be happier with the results. From start to finish, the process was seamless—professional, punctual, and highly efficient. The installation was completed on time, and the difference in air quality and temperature control was immediate. Our family and guests have all noticed the improved and comfort. What really stood out was the attention to detail and the care taken to make sure everything was done right. It’s clear that he takes pride in his work. Highly recommend to any business owner looking for reliable and expert HVAC service!"

"Excellent professional service. The person I worked with was named Eugene. He wore a mask and tried to keep the whole process as clean as possible. My air conditioner was dripping water and needed to be cleaned with some chemicals. Eugene tested the air conditioner to make sure it didn't need to be replaced and a cleaning would not work. He told me the air conditioner was in good condition but needed a cleaning to unclog the pipes and it would stop dripping. He was totally right. After he took it out and cleaned it and then put it back in the window it worked perfectly. It was quiet and dry. Eugene was very fast and did a great job. He was pleasant to work with. He explained things before he did them and asked me if I had any questions. I felt he was very honest and really wanted to help. He only took payment after he completed the job and I said I was happy and satisfied. I transferred money to him via Zelle, but he can take payments using anything...... credit card, cash, pay pal, or whatever. The whole process was fast and easy. I thought I was going to have to buy a new conditioner, but instead it just needed a simple cleaning. I really recommend Eugene and his company. I have read about other companies and how they are not so honest or they do a messy job. Please use this company. You won't regret it. I just found them by accident. Eugene was the fastest company that responded to my email request for help. I read that other companies can be unreliable, but I read good things about Airnizer. They were all true. Thanks Eugene !!!"

"I wish there were a rating higher than 5...that's how good they were. Alex S. & Dimitri were professional, courteous, timely and explained every step. I used them to clean out the dryer vent, but will also be hiring this company to clean out the air conditioning vents as well."

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.
