"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!"

"Mr Justin Barnes did an OUTSTANDING job installing a new PTAC/air conditioning and heating unit. Justin first showed up to evaluate my 15 year old unit - and then without any pressure, discussed my repair options, plus my replacement options. He was totally neutral, and I made my own decision with zero pressure. When I decided replacement was best for me, Justin found the ideal replacement high efficiency PTAC, priced it, picked it up from a warehouse and installed it flawlessly. He also checked in post-installation to ensure it was behaving correctly and that all settings were good. Iâ ve had many appliance specialists in my apartment, and Justin is THE BEST. Good, helpful, frank advice from someone who clearly loves repair and installation, plus helping people - who are freaked out by appliances - out. Justin also prices fairly, and is worth every penny of his wage. Mr Justin Barnes is on your side, and is a gentleman"

"Mel and his team did an excellent job fixing the air conditioner at my business. Initially, the estimate was a little over my budget, but Mel helped me adjust it to fit it, which I really appreciated. If you're looking for a good air conditioning technician, they are very honest and knowledgeable."

"Replaced old outside air Condenser and attic Air Handler with new updated equipment and refrigerant. Dan and Joe did incredible job on probably the hottest day of the year and got the job done fast. They were extremely effcient and and showed great professionalism and honesty. They made repairs in the system that they felt was needed to enhance my new system without charging me for the extra work. I'm sure that another installer would not have bothered to do that. They were very respectful of my Home and took great care to be clean and safe. I highly recommend this company."

"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.
