Cool Knight AC LLC

Cool Knight AC LLC works out of San Marcos, Texas, handling HVAC jobs for houses and small businesses across the area. They take on air conditioning and heating systems with a focus on getting units running steady through Texas heat and winter dips. Years of local experience means they know the typical breakdowns that hit equipment here and they handle installs, fixes, and upkeep without the delays or extra charges that bigger outfits often add. Homeowners in the area call them when systems act up or need full swaps to keep indoor temps steady year round.

They cover maintenance tune-ups, emergency repairs, and complete replacements when old units fail. One homeowner had their AC die at six in the morning and needed a new system the same day after the warranty offered no help. Another switched from a large company that dragged out service calls and pushed unneeded work, then stuck with this crew after a neighbor recommended them for straightforward repairs. Commercial jobs keep stores and offices cool in summer and warm in winter while indoor air quality checks clear out buildup in ducts and vents. They show up ready to match solutions to what the place can afford.

Customers rate the outfit high across the board because repairs last, response times stay quick even on short notice, prices come in lower than expected, and the crew explains options without pressure. Reviews note how the team listens to budget limits and still delivers solid results on everything from full unit swaps to regular service. This pattern of honest, on-time work has earned steady repeat calls from San Marcos locals. DIRT Score 4.84 from 30 reviews on Finds.

“These guys are amazing! We were using a larger company for our ac service and kept having issues. Long wait times, upselling, errors during service calls. My neighbor suggested I call this local company who takes care of his home. After calling and speaking with them I am never using anyone else. In a world full of business first and customer second it is great to have a company that puts the customer first. Always quick service, always honest and upfront about timeliness, pricing and expectations. Save yourself the trouble and just call them first.”

“Man oh man, these guys are unbelievable! I honestly don't know where to start. They're super responsive, knowledgeable, professional, and honest—not salesy at all. They're understanding, super fair, and no one will beat their prices. They'll find a solution for any budget. This is the best kept secret in San Marcos! I found them by chance after talking to multiple other HVAC companies, and no one came close. I don't know what else to say except I'm so grateful for these guys!”

“We wanted to express our deepest gratitude for your exceptional service in replacing our AC unit. Your dedication and professionalism truly went above and beyond our expectations. Thanks to your hard work, our home is comfortable again. We appreciate your promptness and the care you took to ensure everything was working perfectly. Thank you once again for your outstanding service. Sincerely, Amber”

“So our AC took a crap this morning at 6am. Ended up needing a complete new unit and warranty was no help. Cool Knight AC came to the rescue and got us up and running same day!! Can’t recommend this company enough!”

“I am thankful I found Cool Knight AC. I unfortunately have been having AC issues for a couple of weeks and couldn’t find anyone that wanted to come give me an in person estimate. Cool Knight AC came after a service call to estimate and went above and beyond to inspect and explain in detail what my issues were and offered me a very reasonable price in replacement.. The crew was able to get me back up and running which I am grateful for because of the equipment I have in my studio and it worked until they returned to install the new system. They have excellent work ethic and i highly recommend them. They are experts to install with a fair price. Thanks again Cool Knight AC ..”
