Derwyn Johnson A/C & Heating

Derwyn Johnson A/C & Heating operates out of Yoakum, TX as a straight-up HVAC outfit that handles both home and business needs in the area. The company started with family values from a man who knew what it takes to keep hardworking folks comfortable through tough conditions. They focus on kitchen refrigeration gear such as reach-in coolers and freezers along with walk-in units while also delivering solid repair work on commercial and residential HVAC systems. With a decade of direct experience plus college certificates in residential and commercial HVAC/R plus TOP GUN and Manitowoc credentials they bring real know-how on brands like Hoshizaki Scotsman and Ice-O-Matic ice machines.

The crew shows up ready to handle specific jobs like checking window AC and heat units or bringing aging systems back online without dragging things out. Brent has been called out multiple times for quick fixes on older equipment where he spots the problem right away and gets it running again the same day or even next morning after a Friday night call. They have sorted issues on residential setups by testing what they could and laying out clear options when full replacement made more sense than another patch. Service often includes fitting in extra requests on the spot during a visit and sticking to practical steps that match the actual condition of the unit rather than pushing unnecessary add-ons.

Homeowners keep coming back because the work holds up under real use with no shortcuts on quality and prices stay reasonable for the results delivered. Response times stand out since crews arrive within a couple days or even overnight when needed and communication stays clear from the first call through the final check. Fair pricing gets mentioned often along with accurate diagnoses that save money by targeting the real fix instead of guessing. Brent earns repeated praise for prompt arrivals and solid outcomes on repeated service calls. DIRT Score 5.0 from 41 reviews on Finds.

They gave me several options on my ac/heating systems for my house. I appreciate them and would highly recommend this company!!”
