“My experience with Eloy has been amazing. He is very knowledgeable and helped me and my family out. He came over when he didn’t need to at all but he had my AC fixed. He is straight forward and to the point and no sugar coating on anything. He is an amazing HVAC tech and glad we have him and always one phone call away.”

“Eloy is very professional and nice. He knows what he is doing and does it right. I will recommend him to my friends and family. But also anyone looking for good honest service. Thank you Eloy.”

“For the past two years, Eloy has taken care of the unit at my mother-in-law’s house. After calling several businesses last summer, he was the only one who could accommodate us into his schedule. He is reliable, knowledgeable, and trustworthy. He calls me to go over options and pricing before providing any services because I don't live in San Marcos. Thank you for always taking care of my mother in law! Highly recommend”

“I would 100% recommend Mr.Kool’s Air-dition. The owner is very Upfront about everything. Answered all my questions, fixed my ac as fast a he could. My coil needed to be replaced for my AC but unfortunately it was no longer under warranty he made sure to let me know the price of everything upfront before continuing with any work, making sure that I was OK with everything. He gave me the breakdown of all his work and making sure I understood what I was paying for. He also spoke Spanish which was a plus because it also helped in translation to my husband about what was wrong with our ac. This is the first ac repair man that I have found to answer on a weekend and come out on an emergency call. Thank you again Mr.kools My ac is working amazingly!”

“Eloy is a true professional! Was on time and was very respectful to us and our home. Took the time to explain everything and was very upfront and honest throughout the whole process. Eloy was able to fix my issue and get my family feeling comfortable in this heat. The price point for the work performed can't be beat! Any further AC issues Eloy will be my first and only call!”

“I called numerous local AC companies in the area of Seguin & New Braunfels and they couldn’t get me on the schedule for several days. I then contacted Eloy with Mr. Kools out of San Marcos and he was ready to work! He came out to repair my uncles faulty motor on his AC unit. Eloy had the issue diagnosed in a very timely manner. He quickly took on responsibility of finding the exact motor that was needed. He rushed to pick it up and had it replaced in no time at all. I highly recommend his small business over any other AC company in my area, you won’t be disappointed!⭐️⭐️⭐️⭐️⭐️”

“My AC stopped working during some of the hottest days ever recorded in July, so i called Mr. Kool to set up an appt. He was able to come out in short time and get to work. I really appreciated Mr Kool's honesty and knowledge on what i was dealing with and gave me options. He let me know what and why he was doing each step of the way and gave me advice on how to prevent the issues going forward. I greatly recommend Mr Kool because of the wonderful experience i had and will only use him going forward. Thank you Mr. Kool!”

“We have used this company twice now for complete removal and cleaning of different window units in our home. Not only did Eloy do a great and thorough job cleaning the units but he is professional and extremely quick to respond. Would definitely recommend this company for any AC and heating needs.”

“Nice guy and responsive when others might not be. Was a bit disappointed to pay $120 for an add-on service while he was already here. The add-on was just to install a smart thermostat where I already had c-wire installed so a 5-10 min service. I would’ve and fully could’ve done it myself as I thought it needed to be recalibrated professionally when it’s changed out.”

“Lost AC last night, contacted Mr. Kool’s Air-dition on Saturday after 4-5 company’s told me it would take a week to respond. He was here within an hour, AC back to working within 15 minutes. He had the replacement part ready, and knew what he was doing. Very friendly and couldn’t be more happy with the service!!!”

“Eloy went above and beyond to take care of our HVAC needs. We had a terrible experience with Airtron and Eloy came to the rescue. He went above and beyond to take care of our needs. I will definitely be a loyal customer from here on!”

“Very happy with my experience with Mr. Kool's! They really went above and beyond! Came out quickly and kept me in the loop about everything! Even spoke to me before hand about what was wrong with my unit, what needed to be done and how much it would cost before doing anything. They really are committed to great service and very friendly. Whenever I need the services of my AC/heat again, I will definitely be calling this company!”

“Needed a water heater replaced and was done professionally and fast. I was expecting a quick connect on my water lines, but the tech actually put soldered connections for a more secure fit. Now all the family can take hot showers and never runs cold.”

“He did a great job 👍. Was here when he said he was. Always let us know when he was a few minutes away. He even came and worked after 6 pm. Got the job done when he said. Very affordable that's another plus. Definitely will call him again if ever needed.”

“A great and reliable company, I was having problems with my unit and wasn’t getting enough cold air even after running it for a couple of hours still no cold air, so then I gave Mr. Kools a call and they came within an hour and the same day I was getting cold air. I highly recommend for EVERYONE that’s having a problem to CALL CALL CALL ⭐️⭐️⭐️⭐️⭐️!!!”

“I’m so grateful for mr kools coming to my home and fixing my heater. It was 40 degrees out and the heater had failed from previous owners lack of maintenance. It was straight to the point and quick response. Will definitely be doing business with Mr Kools again”

“I highly recommend Mr.Kool on you’re next A/C repair/maintenance. Mr.Kool not only fixed the issue but also explain everything in detail. He was very easy to talk to, communicated quickly. Thank You Mr.Kool!”

“Oh man with the summer coming up I knew I had to get my tune up/system serviced . Little preventative maintenance goes a long way. And whoa talk about a difference it makes. My system is running so much better. Really grateful I should’ve taken care of this long ago. Thank you again”

“They replace my a/c and heating unit did a great job also worked on my mom's. I higher recommend him.”

“This is the kind of guy that I like doing business with. He genuinely wants to help people and just make a living while doing it. He'll go out of his way to make sure you're set for whatever you need and not try to break you while he does it. I won't use anyone else.”
