Rooftop Unit (RTU) Installation & Replacement

Rooftop units (RTUs) are the backbone of many commercial buildings in Phoenix. These self-contained systems offer both heating and cooling in one unit and are designed for rooftop mounting to save interior space.

At Hometown HVAC, we specialize in the installation and replacement of single-zone and multi-zone RTUs, with expertise in equipment selection, curb prep, electrical connections, duct interface, and control integration.

Our RTU installation services include:

  • Load calculation and equipment sizing
  • RTU model selection based on space usage and capacity
  • Rigging and crane coordination for rooftop delivery
  • Ductwork, power, and gas line connection
  • System startup, testing, and commissioning
  • Thermostat or building automation integration

We install Armstrong commercial RTUs and can also replace existing equipment with units from other major brands.

When to Replace a Commercial HVAC System

A failing HVAC system doesn't just affect comfort — it can disrupt daily operations, drive up utility costs, and create an unsafe or uninviting work environment. If your building's HVAC system is struggling, it may be time to consider a replacement.

We offer no-obligation assessments and honest guidance on whether repair or replacement is the best solution for your building and budget.

Signs your commercial system may need replacement:

  • Inconsistent temperatures across zones
  • Sudden spikes in energy consumption
  • Loud operation or unusual noises
  • Costly or repeated repairs
  • System is over 12-15 years old
  • Air quality complaints or poor airflow

Our Customer Testimonials

5/5

"We recently had an issue with our Trane AC unit, and Shelby from Hometown HVAC did a fantastic job. He quickly diagnosed the problem, replaced the capacitor, and had us back up and running in no time. Shelby has over 30 years of HVAC experience and specializes in residential work, with commercial experience as well. He's professional, knowledgeable, and trustworthy- showed up in a branded truck and uniform, explained everything clearly, and didn't try to upsell us, just focused on the repair. His pricing is very reasonable. He mentioned that he works in North Scottsdale frequently and handles maintenance, repair, and emergency calls. I'd highly recommend Shelby and Hometown HVAC to anyone in the area who needs reliable AC service."

Steve Nola, Nextdoor
5/5

"I have been a GC for over 30 years and when I came to AZ 7 years ago, I met Shelby even before he started HomeTown and have worked with him ever since. My remodel projects are not easy, and Shelby puts in the time on the front end and helps me design. He is very knowledgeable and with his expertise, we can put together an affordable and functional system that I know will work. He has strong communication skills and puts together a clear and detailed estimates. I know that I am only as good as the people around me and that is why I value working with HomeTown HVAC."
