Ylong was great since the initial communication. Came over, inspected my split a/c units, gave me a fair price to repair and proceeded two days later to complete the work as promised. Everything seems great! Great person, great work! Thank you!

YL Smart AIR Inc is responsive, punctual, and great value for money. I trust the work quality is just as good (the repair was just carried out).

Yi Long was great. He was professional, knowledgeable and meticulous in his work. He cleaned 4 indoor units, 2 outside compressors, repaired leak to the compressors and added freon - all at a reasonable price. I would highly recommend him. He will definitely be my go to guy if I have need of HVAC service again in the future.

I had a sudden boiler failure and had no hot water or heat in my home as a result. Yilong came out to me within 2 hours, spent all the time needed to diagnose the issue and then went and got the very hard to find part for a same day complete repair. I have only positive things to say about this company and highly recommend anyone needing them to use them without hesitation!
