Air Handlers

Repair, replacement, and maintenance for air handling units in every facility type, from office buildings to refineries.

Commercial Air Handler Services in San Antonio

Air handlers are where comfort actually happens — moving, filtering, and conditioning the air your building breathes. When an AHU underperforms, you get hot spots, poor air quality, and rising energy costs. Flo-Rite Mechanical has serviced commercial air handlers across San Antonio and beyond since 2014.

AHU repair and rebuilds, motor and bearing replacement, coil cleaning and replacement, VFD installation, filtration upgrades, and belt/pulley service — for facilities including offices, medical buildings, schools, warehouses, refineries, hotels, and retail.

"I just had my 15 year old system replaced with a new Lennox system. The crew at Flo-Rite did a clean & excellent install. They showed up on schedule and answered all my questions. If your looking for service or need a completely new AC, I highly recommend calling Flo-Rite for the job."
