"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!"

"I honestly cannot say enough good things about Justin. Our old A/C stopped working for some reason and just started delivering fan only, no real cooling. I called several places all of whom said they did not service window units. I finally got one place that said they did and could be there in two weeks (!). This when we were on a miserable stretch of insufferably hot, humid weather. I somehow found Justinâ s details after broadening my Google search for local help. Where to even begin. Not only was he there the same day (within four hours!) but honestly and accurately diagnosed the problem. He got the A/C back up and running in less than an hour with an effective repair to a worn-out part and explained why we would need a replacement part which he would be back to install as soon as he could source it. Again, I cannot say enough positive things about Justin and his work and would 100% recommend him to others. I am lucky to have found him."

"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

"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."

"I spoke with Mike and sent a picture of the problem I was having with our thermostat. He assured me that they could handle it while others I spoke with were unsure if they could do it or not. He confirmed for 8:30 the next morning, called me 20 minutes before Dan showed up and did a terrific job. My wife was home with him and said he was professional, knowledgeable and extremely nice. We’re so please that we’re having them assess our A/C unit come the spring. Highly recommend!!"

"Moh and his partner were such sweet guys, explained everything to me before starting anything and took the time to make sure everything part of air conditioning system was cleaned and in perfect working order at the capacity the air conditioner should be working. They went above and beyond. Highly recommend them!!"
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.
