Frequently asked
Yes, I specialize in commercial rooftop units (RTUs) for retail strip malls. My work includes servicing and replacing key components like RTU economizer damper actuators, belt-drive blower service kits, and roof-curb flashing and safety rail systems. I also handle rooftop crane rigging harness setups when needed for unit installation or maintenance.
I've been in the HVAC business since 1998, which means I’ve been working in this field for exactly 28 years as of 2026. For all RTU installations and repairs, I provide a standard one-year parts and labor warranty on my work to ensure customer satisfaction.
I offer a dedicated 24/7 emergency hotline specifically for urgent no-heat/no-cool situations involving commercial rooftop units. This ensures that if your strip mall’s RTU fails during off-hours, you can get immediate assistance without waiting until regular business hours. Emergency calls are answered by me directly.
Absolutely. I regularly install and repair roof-curb flashing and safety rail systems around commercial rooftop units to ensure compliance with building codes and prevent leaks or access hazards. These are essential elements in maintaining both functionality and safety of RTU installations in strip malls.
