"⭐⭐⭐⭐⭐ 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!!!"
