Meet Felix Scott, founder of TeraTax Lab. Discover our mission, HVAC experience, and why Phoenix homeowners and businesses trust us with their cooling needs.

Your Local HVAC Expert with 15+ Years of Hands-On Experience

Hi, I’m Felix Scott, founder and lead technician at TeraTax Lab. I’ve spent the last decade and a half working in residential and commercial HVAC systems across Arizona, specializing in air conditioning maintenance, emergency repairs, and performance optimization.

I hold certifications in:

  • EPA Section 608 Certification
  • NATE Certified HVAC Technician
  • Arizona Contractor’s License – HVAC Systems

Beyond certifications, what sets me apart is the personal commitment I bring to every job. When you call TeraTax Lab, you’re not dealing with a corporate chain — you’re working with a local expert who truly cares about keeping your system efficient, safe, and reliable.

Why We Started TeraTax Lab

Solving a Common Problem with Uncommon Dedication

After years working for large HVAC companies, I kept hearing the same complaints from clients: long wait times, rushed repairs, and no follow-up. I knew Phoenix homeowners and business owners deserved better.

That’s why I launched TeraTax Lab — to provide responsive, personal, and trustworthy service that never cuts corners. Whether it’s a basic tune-up or an after-hours emergency, we treat your system like it’s our own.

Our Mission & Values

At TeraTax Lab, everything we do is guided by three core principles:

🛠 Reliability – We show up when we say we will, and we get the job done right the first time.
 🤝 Honesty – Transparent pricing, clear communication, and no unnecessary upsells.
 ⚡ Speed – Same-day service available, with 24/7 emergency response you can count on.

Our goal is to become your go-to AC partner — not just for one fix, but for the long haul.
