"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."

"⭐⭐⭐⭐⭐ Absolute Pros – Highly Recommend Legend Air! I cannot recommend Legend Air enough! We recently had them out to troubleshoot our central air and heating system, which ultimately required a full replacement of our outdoor condenser unit. From start to finish, the entire experience was flawless. * **Honest & Diagnostic Expertise:** The technician arrived right on time, quickly diagnosed the issue, and took the time to explain exactly what went wrong with our old unit. I never felt pressured; they laid out all our options clearly. * **Flawless Installation:** The crew that handled the condenser replacement was professional, efficient, and incredibly respectful of our home. They worked fast but didn't cut any corners, ensuring the new central AC and heating lines were perfectly calibrated. * **Top-Tier Customer Service:** Their communication was fantastic throughout the whole process, and their pricing was fair and transparent."

"We were desperate to find someone to repair our central air conditioning unit. We were not able to move into the house and everyone that we called was not able to accommodate us because of the recent heat wave. All Weather was able to get a technician to us within 2 days. Nuri was amazing and showed my husband how everything worked and what repairs needed to be done. By the time he left, we had a cool house and were able to set up our movers. Thanks to Angie’s list, I found a reputable company that was reliable and efficient. We can rest easy! Thank you!!!"

"Joe was very respectful, personable and patient and explained what he would do and why to ensure our central air would finally work. It took ALL DAY but he installed an exhaust fan in the ceiling with attic ducts to draw out hot air, performed a chemical wash of the condenser, installed a wifi thermostat that required a new transformer and taught me how to use it. I LOVE being able to monitor indoor and outdoor temps on the app and I can see that our summer tenants are using it and that the AC is working great when needed."

FAQs for air conditioning projects in Brentwood, 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.
