"They definitely earned this 5 ⭐️⭐️⭐️⭐️⭐️ review!! I can't say enough good things about VIP HVAC, they truly went above and beyond! Hector, the owner, came out with two of his crew members the day before the 4th of July to replace both my AC and furnace. They arrived right at 8am and worked nonstop until 6:30pm to make sure everything was done perfectly. Throughout the job, they found a few unexpected issues, but Hector and his team kept me informed the entire time and handled everything with professionalism and care. I was so impressed by their hard work, attention to detail, and clear communication. If you’re looking for a trustworthy and dedicated HVAC company, I highly recommend VIP HVAC. Hector and his crew are the real deal!"

"The entire Green Ductors team is awesome. From the start, Igor reached out to me shortly after I entered my HomeAdviors request. Unfortunately, I was unable to reply to him right away. He was very good with following up and when I was finally able to respond I had the pleasure of working with Olga. She was very agreeable and really worked hard to find a time for the work to be completed. When duct cleaning day arrived, Alik arrived a few minutes before the scheduled time (8 AM) and waited in my driveway until I motioned to him that it was ok to start. Before he entered my home, he removed his shoes. We walked around the house looking at the vents and my heating system. Next, he brought in all of his machines and gear. He worked tirelessly for almost 6 hours cleaning all of the vents (dryer vent included) He took a bunch of before (YUCK!!!) and after (sparkling clean) pictures. He was really a master at his craft. My entire family noticed that by the next morning our allergies felt better, our noses less stuffy and the air in our house seemed much cleaner. I will not wait as long as I had previously for my next air duct cleaning. I would not hesitate to hire Green Ductors again. In an age where many home improvement contractors talk a big game and then don't deliver, Green Ductors delivered a top notch service at a reasonable price. My sincerest thanks to them for a job well done."

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.
