Guaranteed A/C & Heating

Guaranteed A/C & Heating operates out of Houston, Texas as a straight HVAC outfit that handles the full range of cooling and heating work for local homes. They focus on keeping systems running through the long hot summers and occasional cold snaps that hit the area, with crews that show up ready to tackle both routine upkeep and full replacements. Homeowners in the city deal with heavy use on their equipment year after year, and this company steps in to handle the repairs and upgrades that keep indoor temperatures steady without dragging things out.

Their work centers on replacing old evaporators, swapping entire units that have reached the end of the line like a 1984 model, and running thorough diagnostics on systems that stop cooling properly. Corey leads jobs where he explains the issues in plain terms so the homeowner knows exactly what needs fixing, and the crew follows through with clean installs that leave no mess behind. They turn up on schedule, quote competitive prices compared to other outfits, and check back after the job to confirm everything is working right, whether it is a quick evaporator change or a next-day full unit install.

Customers keep pointing to the same strengths that add up to strong results on every job. They note the crews stay honest about what is needed, communicate clearly from the first visit through completion, and deliver solid work at fair rates without pushing extras. Speed shows up in how fast they respond and finish, while quality comes through in the lasting fixes and follow-up calls. That steady pattern across dozens of jobs builds the kind of track record that stands out. DIRT Score 4.92 from 59 reviews on Finds.

“I don't normally post a lot of reviews but I just had to for Guaranteed AC. Corey and his team are great at what they do. Communication is flawless. They are very honest which is an important value to me. It's difficult to trust some people but I never have this problem with Guaranteed AC. They communicate effectively to show why something needs repair and even gives advice on how to maintain systems to keep it lasting longer. I've been with Corey for a few years now and am happy to have found Corey.”

“Service was great! I was referred to this company, representative came out and was very informative. My unit was very old (1984) company was in the next day with a new unit and no mess. Out of four company I received quotes from he cared about the consumer not about making an extreme profit. Definitely is my A/C company!”

Also helped that the price they quoted was the most competitive I received. They followed up to make sure everything was running smoothly and I’ll be using them going forward.”

“Corey came out and not only quickly diagnosed my A/C needs, but thoroughly explained everything to me. He was happy to spend the time being sure that I understood everything that was happening with my system. I highly recommend Guaranteed AC to anyone who not only wants informed professionals, but also a company willing to take the time to explain the details of the scope of work.”

“Guaranteed Air is customer friendly and ensure they fully take care of the issue. From setting the appointment, pre-appointment confirmations, and follow up, they are very good communicators. My air conditioner was fixed correctly the first time and I have 100% confidence in Corey's diagnosis of my ac.”
