About Millennium A/C
Millennium A/C is a family-owned, Latino-owned HVAC company serving Mission, Texas and the greater Rio Grande Valley since 2010. Owner Jordan Baez built the company on a straightforward promise — honest work, fair pricing, and a technician who explains exactly what’s wrong before touching a thing — and fifteen years later that promise has earned a perfect 5.0-star Google rating across more than 1,300 reviews. From a physical storefront on North Glasscock Road, Millennium handles residential and commercial HVAC across all three RGV counties, 24/7.
Our Story
fifteen years keeping the Valley cool
Jordan Baez started Millennium A/C in 2010 with a clear understanding of what South Texas homeowners actually need. In the Rio Grande Valley, air conditioning isn’t a comfort — it’s a necessity, with triple-digit heat that stretches for months and doesn’t forgive a system that quits. A dependable, honest HVAC company was the whole idea, and the company has spent more than a decade proving it Valley home by Valley home.
What sets Millennium apart shows up in the reviews, where customers name the owner and the technicians personally and use the same words again and again — professional, honest, they explain everything and take pictures, no surprises. The team is fully bilingual, and Millennium is proud to be Latino-owned and rooted in the community it serves. Se habla español, siempre. For families across the Valley, that combination of technical skill and plain-spoken trust is why Millennium has become the name neighbors pass along.
