Cleary Zimmermann Engineers, Llc

Cleary Zimmermann Engineers, Llc works out of San Antonio, Texas on HVAC engineering projects as part of their MEP focus. The firm handles mechanical systems for buildings and industrial sites across the state, using their setup in multiple cities to cover jobs that involve air handling, ventilation, and climate control. Homeowners and contractors in the area call on them for input when local heat and humidity put heavy demands on cooling equipment and ductwork. Their background centers on designing and reviewing these systems so they hold up in Texas conditions without constant breakdowns or high energy use.

They take on design work for building HVAC setups along with commissioning and oversight during installation. Clients have dealt with the group on projects where knowledge of the systems mattered, as Zed Hernandez noted the team came across as very knowledgeable and personable. At the same time Mark Dawsey left a comment about funnel cakes after one job, while Eloy Figueroa ran into trouble getting past the gate keeper and Timothy Alvarado called the whole thing bad. These details show how the firm manages day to day coordination on HVAC fixes and new installs but leaves some customers with uneven results depending on who they reach.

Feedback from the reviews points to inconsistent results in speed of response, quality of the work delivered, pricing that did not always match expectations, and communication that fell short for several people. A few noted solid technical input while others ran into blocks that hurt the overall impression of reliability on HVAC jobs. This mix pulls the score down across the full set of reviews. DIRT Score 2.62 from 10 reviews on Finds.
