"I highly recommend Absolute Zero. Kyle didnâ t try to sell me upgraded equipment, he sold me what works sufficiently and what he would install in his house. I got a few quotes for the central AC and his price was the lowest. Installed in the attic that will be renovated into a room, he worked with me and planned and installed the air handler unit and all the ductwork where heâ d leave the center of the room open and did a great, clean job. He said the AHU upstairs and condenser unit outside would be quiet, I was shocked at how quiet everything was. He protected furniture and floors while they worked and left the house clean and tidy after leaving. Iâ m extremely pleased with the work and have already referred him to others."

"Just can't say enough good things about this company. I signed a contract they came on time. They installed new residential carrier air conditioning unit. Did a complete clean up when they were done. Everything is working just fine. I would recommend this company if you're considering putting in home air conditioning system."

Customers say: Quality work
"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."

"They were great! Family run business who were with us every step of the way. It took us a lot of time to decide on what ductless a/c units we wanted and exactly where we wanted them installed but Keith was so helpful working with our many requests and helping us save money to stay within our budget. Highly recommend these guys."

"I had the equipment replaced, a brand new, super high efficiency, fancy, lovely stuff. It's a central air system, and it's Lennox equipment. It's high efficiency. You can get it for less than that, but you're not gonna get the high efficiency quiet and all that kind of stuff. I had received other quotes which were like more money for the same system. I have been using them since 1986. No complaints. They do their thing, and I can't fault them. I have a service contract with them for this."

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.
