"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!"

"This was the first time I hired a company to professionally clean my air ducts and dryer vents. Green Ductors worked well with all of my needs. They were professional and courteous. Igor took the time to explain the process from start to finish, what work was included for the price, and cleared up all of my questions. Igor called 24 hours before the start of the job to confirm. The technicians arrived 10 minutes before their scheduled time and explained the process once more! Ivan cleared up additional questions I had and completed a thorough check of my HVAC system, ducts, and vent. He took photos and explained their assessment of my system. They took their time and were mindful. They carefully moved furniture if they needed to and placed it back in its original position. Once the job was complete Ivan took photos and explained the work they completed. He sent me both sets of photos and shared some maintenance tips. I highly recommend Green Ductors!"

"I highly recommend engaging Raynor Services for your heating/air conditioning needs. Our technician, Matt, was very friendly, courteous and efficiently diagnosed and planned the remediation of our heating problem. He took the time to point out what was wrong and provided some extra measures we could take, should we decide to, in the future. No sales pitch, no pressure to add additional costs. Extremely satisfied with Raynor’s friendly service, quick response (less than 1.5 hrs from my call) and low costs to return our heating system back in working order. We will continue to call on Raynor Sevices for all of our heating & ac needs."

"Overall, the experience was flawless. We are very happy with our heating system and it has saved us a tremendous amount of money. (David said it would) We are very happy with the 2-zones he provided us, we can keep the main rooms warmer and the addition cooler when no one is in it. Also cost effective. They came the day they said they would and finished on-time.

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.
