"Ray's HVAC responded quickly to my request to repair my furnace, which could not start this year. They were able to find and fix the real cause of the issue - a bird net in the PVC pipe which blocked the air flow, and made my furnace is working again!"

"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!"

"I was in desperate need of an AC unit repair and Kyle came to the rescue. Iâ ve owned my home since 2019 and have been looking for and honest and reliable AC technician. Iâ ve used a couple of other technicians but Kyle will be my go to moving forward. He kept me informed of everything he was doing and educated me on how my unit should be running. He even gave me info for what filters I should be purchasing to help my unit run efficiently. He gave me several options with regards to repairs and I went with the higher priced option because it was so reasonable and I didnâ t want to cut corners. I will be scheduling my routine maintenance with him for the summer and winter. Iâ m so happy I finally found an AC technician I can rely on. I highly recommend him."

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.
