About Aire Systems LLC in El Paso, Allen, and Dallas Metro

A Small Service Truck, a Big Commitment to Honesty

Aire Systems LLC is an EPA-certified HVAC company serving families throughout El Paso, Allen, Dallas, Plano, McKinney, Frisco, Richardson, Garland, and surrounding areas. Founded 13 years ago by Leo Montenegro and a business partner, the company started with a single service truck and a simple philosophy: treat every call like a friend asking for advice, not a transaction.



From the beginning, the approach was clear—repair systems to keep costs down for customers instead of recommending unnecessary replacements. That principle still guides every technician today. When you call Aire Systems, you work with a team trained to diagnose accurately, explain options clearly, and prioritize what's actually in your best interest. Every installation is load-calculated to match your home's specific needs, not just swapped out with the same equipment that was there before.


What began as word-of-mouth referrals has grown into a trusted regional provider with 10 employees, but the core values haven't changed. You'll experience the same honesty and friendliness that built the company, backed by manufacturer-specific training and NATE-certified technicians who know the technical side of HVAC inside and out.

Local Ownership, Technical Expertise You Can Verify

Leo Montenegro and his business partner didn't set out to build the biggest HVAC company—they wanted to build one where customer care came first. That meant taking the time to explain what's wrong, walking homeowners through repair versus replacement decisions, and never upselling equipment that wasn't necessary. As the team expanded from one truck to ten employees, that hands-on, personable approach stayed intact.


The Dallas Metro and El Paso regions experience temperature extremes that put real stress on HVAC systems—summer heat that pushes air conditioners to their limits and occasional winter cold snaps that test heating performance. Aire Systems technicians understand these patterns and how they affect equipment longevity, which is why proper diagnostic work matters before recommending any solution.


Every technician on the team is EPA-certified and undergoes manufacturer-specific training, ensuring they're up to date on the latest systems and installation standards. The company is registered with the Better Business Bureau, and NATE-certified technicians handle the technical work—credentials you can verify independently. When a technician shows up, they're not just experienced; they're trained to current industry standards and equipped to do the job right the first time.

What You Experience Working With Aire Systems

When you call Aire Systems, you're working with a locally owned company that's been serving your community for over a decade. The team approaches every service call with the same mindset Leo and his partner had on day one: honest advice, thorough diagnostics, and repairs that prioritize your budget. You won't get a sales pitch for a new system when a repair will do the job, and you won't get a one-size-fits-all recommendation when your home deserves a load-calculated installation tailored to your square footage, insulation, and layout.
