Tekton Mechanical was founded by James Mathisen, an
AZ Native HVAC professional who began his career in 2017. After nearly a decade in the industry, James saw a growing need in the Valley for honest pricing, transparent service, and solutions that truly put the customer first.
In 2025, he launched Tekton Mechanical with one mission: deliver reliable HVAC service, without upselling,
pressure tactics, or inflated costs. We believe homeowners deserve fair prices, quality workmanship, and clear communication every step of the way.
Today, Tekton Mechanical continues to serve the Valley with integrity, expertise, and a commitment to doing the job right — the first time.

With proper maintenance, an HVAC system can last between 10 to 15 years. However, the lifespan can vary depending on the type of system, how well it's maintained, and how frequently it's used. Regular servicing, such as changing filters, cleaning ducts, and scheduling annual inspections, can extend the lifespan of your system and help it run at peak efficiency. If your system is approaching the 10-year mark and showing signs of inefficiency, it might be time to consider a replacement or upgrade to a more energy-efficient model.
