"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!"

"Ali came over to our home when we called with a concern of the air flow in our central air conditioning system. He checked the return, the air flow, the temperature at all of the vents, and the entire system. It had more to do with the age of the system and gave us suggestions on how a different filter could increase the air flow. He did all of this and refused to take any money for his time. He is a true honest professional and someone that we would recommend to everyone."

"Provided a fair price for a new Rheem air conditioner condenser and air handler. Price was very competitive. Pleased with the work done. Had several productive conversations with the owner regarding the best fit for our needs and budget (1-stage versus 2-stage; SEER2 rating). Pleased with what we wound up deciding on."

"They were extremely professional and friendly. Very tolerant of the conditions in the house and that I have 9 cats. They had to comply with my condo regulations, which was time consuming. It was also difficult that the major part of the unit was in the attic. Very tight and HOT!"

FAQs for air conditioning projects in Oyster Bay, 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.
