"Vinny went way out of his way to go to Montauk to give me an estimate on an air conditioning unit in the downstairs and upstairs. He gave me a great price and kept me informed as to when he was picking up the ductless units and when he was going to install them. He and his son were professional and did a great job."

"I cannot thank “Natural Breeze” enough for the fantastic job they did installing my new hvac system. I had previously committed to doing business with another hvac company during the heat wave who did a horrible and incompetent job with my hvac system. It was truly a horrible experience but thank god I was able to get out and terminate my contract due to their negligence. I was referred to Luis whom I reached out to and he responded to my emergency situation quickly. He is truly a reliable professional and having talked with him he is extremely knowledgeable and informative. He is a man who works diligently and has great morals and integrity. I am a dedicated as a life long member to Luis and his team, he goes far and beyond to make sure his clients are completely satisfied and his prices are definitely reasonable. Thankyou Mr Luis and to your crew for the exceptional work that u have provided. I highly recommend this company if you are looking for a A+ hvac contractor ."

"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!"

"Absolutely fantastic interaction and experience through the whole process. He did a fantastic job installing the mini splits in the new house and was very professional through the whole process. The insulation looks clean and works fantastic. The new high Seer rating and smart units make it easy to manage the house from afar. In just the first couple days I'm already saving compared to the old central air."

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.
