"After a number of calls to various companies, I reached out to home advisor looking for help ASAP with my central air that wasn't working on a Sunday when it was a 95 degree day. Within 2 minutes my phone rang and it was Kevin from KN heating and cooling. Kevin was at my house with 15 minutes. Not only did he figure out what was wrong and fix it, he found a number of other issues that need to be taken care of. Kevin was amazing and even walked me through what he was doing and explained everything to me. Not only do I recommend him, he's will now be my go to for service on my boiler and central air. Outstanding service and extremely reasonable! Wish I had him do the initial install!"

"Everything went great. The crew arrived right on time and was very polite and professional. Ali explained everything beforehand and the work was done exactly as described. After installation there were some minor adjustments to be made and Ali responded right away and took care of the problem. He was also able to get the ducting corrected to a part of the house that hasn't had ac for many years. I was very pleased with Ali and his crew."

"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."

"Replaced old outside air Condenser and attic Air Handler with new updated equipment and refrigerant. Dan and Joe did incredible job on probably the hottest day of the year and got the job done fast. They were extremely effcient and and showed great professionalism and honesty. They made repairs in the system that they felt was needed to enhance my new system without charging me for the extra work. I'm sure that another installer would not have bothered to do that. They were very respectful of my Home and took great care to be clean and safe. I highly recommend this company."

"I highly recommend them my central air stopped working at 7pm during one of the hottest day of the year and we were under a heat advisory. After call several other companies and nothing and contacted advance where one of their employees herbie came out and was at me house in 15 mins (this was around 930pm) after about 1 hr of his time my unit was up and running. He definitely saved the day especially having a 7 month old I couldn't take any chances. Highly recommend herbie was very professional and knowledgeable diagnosed and had it fixed in not time."

FAQs for air conditioning projects in Bayville, NY

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.
