Luis' Cooling And Heating Services

Luis' Cooling And Heating Services operates out of Round Rock, Texas, and focuses on HVAC work for homes throughout the area. The crew handles air conditioning and heating systems that take a beating from the local heat and sudden temperature swings common in central Texas. They step in for full repairs on units that quit without warning as well as routine checkups to keep everything running through long summers. Luis and his technicians cover both cooling and furnace jobs, showing up for houses where bigger outfits often delay or miss the mark entirely. Homeowners call them when systems break down overnight or need attention to stay comfortable year round without unnecessary delays.

Luis heads out to homes and tracks down AC units other crews overlook, such as the second system one family could not locate for months until he searched thoroughly and solved the problem. He walks through every diagnostic step with clear explanations and proof of the issue so owners understand exactly what broke and what the fix involves. Technicians have driven across town to grab a needed part and returned the same evening to finish the repair instead of leaving the house without cooling. They respond to sudden overnight breakdowns with prompt arrivals, full checks on the unit, and straight talk about results before any work begins, covering tune ups, part swaps, and complete system fixes in one visit when possible.

Customers return because the crew shows up fast, explains problems without confusing terms, and stays until the repair holds steady. Reviews note strong communication on hidden issues, real attention to detail during diagnostics, and extra steps like fetching parts same day to avoid follow up calls. That steady approach shows in every job from quick maintenance to locating and repairing tough AC setups. DIRT Score 4.99 from 37 reviews on Finds.

“Louii’s AC is the only company I will have out to handle my AC repairs and maintenance from here on out. Prompt, good communication, informative, and detailed all diagnostics with evidence so I understood what work needed to be done and how they accomplished the job. Our AC went out overnight, and they were so accommodating by squeezing us in before their first scheduled job of the day. Cannot thank them enough for their professionalism and attentiveness to a Texan’s worst summer nightmare!🤣 I have enrolled in their maintenance program to have them visit twice annually to ensure proper functioning of our system- absolutely worth it!”

“Would absolutely recommend!!! Luis came out to our home and was so knowledgeable, thorough and friendly. We have had other technicians from other businesses come to our house and no one else was able to find our second A/C unit. Luis was diligent and thorough so was able to find it and fix our issue. He and his team were fast, cleaned up any mess they made when doing the repair and educated us on what we need to do for A/C maintenance. Best A/C service experience ever!”

“The technicians went above and beyond with their service. They came out early this morning, thoroughly examined my AC unit, and quickly identified the issue and the part needed for repair. They then drove across town to pick up the part and returned later that evening to complete the repair. Exceptional customer service from start to finish. Hands down the best repair service I’ve experienced. Highly recommend!”
