Kosub Air Conditioning

Kosub Air Conditioning operates as a local HVAC outfit serving Wilson County, Texas, from a base near Elmendorf. They focus on air conditioning and heating work across rural spots like Floresville, Kicaster, La Vernia, Stockdale, and Poth, plus surrounding farmsteads and businesses. The team knows the county roads and the demands of South Texas country properties, handling both residential and agricultural systems that face heavy use in the heat. Licensed under TACLA29221C, they stay ready for the mix of home units and commercial setups that homeowners and operators need fixed without long delays.

Their work covers full AC repair, emergency calls, and installations built for lasting performance in rural conditions. Technicians such as Tyler and Frank handle jobs like flushing pipes in the system, swapping old thermostats that no longer regulate properly, replacing blown capacitors on the unit, and cleaning the outside components to restore full function before the summer peaks. They respond to calls fast, often within hours even after regular hours, explain the issue and costs on site, show the problem indicators directly, and finish with maintenance tips to avoid repeat breakdowns. This approach keeps systems running through the demands of Wilson County weather and property types.

Customers keep coming back because the crew delivers solid results without extra hassle, shows up when promised, and keeps everyone informed at each step. High marks come through on the quality of the fixes, the quick turnaround on service, and clear talk about what needs doing and why. That steady performance across hundreds of jobs in the area builds real trust with locals who need reliable HVAC help year after year. DIRT Score 5.0 from 393 reviews on Finds.

“I called cosmic AC after receiving a postcard from then for an $89 summer check. I received an appointment that same afternoon. The tech came in and flushed the pipes in the ac, checked the thermostat and recommended getting a new one (mine was very old and not working well),installed it and then ween out side to check the unit. It needed freon so I had him add that also. Very nice, knowledgeable man Did the job quickly and nearly. I have used Cosmic for years and am always pleased with their work.”

“It was a very nice experience. Tyler located problem rather quickly, explained the problem and cost of such before he proceeded. Took me outside to show where indicators of the problem are located. He explained the Spring maintenance offer your company provides to help prevent this type of issue. He was quiet, thorough and a genuine pleasure to deal with. I am very pleased!”

“Frank came out and replaced the capacitors that were blown and answered all my questions. He was very patient and courteous. He also cleaned our outside unit and had us up and running just in time for the summer heat! Thank you Cosmic Air Conditioning and Heating! (Not only do we choose and recommend their service but my mother does as well. She also gets her unit serviced from them as well) Thanks again!👍🏻”

“Cosmic is always quick to respond to my calls, even after hours. They got me on the schedule for a technician to be at my house within 3 hours of talking to a rep. The techs are always professional & thorough.”

“Arron and his team never disappoint. They find ways to prioritize your service requests and complete the tasks to satisfaction. I've been with them for probably 15 years covering 3 houses we've moved in, and they have provided quality service. Unless I have a reason to move to another company, I won't.”
