“I have been a customer for years, and it was recommended to get a new unit about 2 yrs. ago. Saved and with income tax and stimulus, I finally decided to get the replacement. I am extremely pleased, and highly recommend All Service. Work was done by Daniel and Emmanuel. Great job was done at the minimum time estimate.”

“My air conditioner broke at 7 p.m. on a Friday night they had someone come to my house at 10 p.m. I was really going to go running motel but I waited the three hours out and this Texas heat Louis came best technician I've ever seen had my AC up and running in less than 30 minutes and this man was still going to another house before he called it a night and started over again the next day”

“Leo and Danny came to the house after hours and completed the job quickly. They were a little bit past their estimated arrival by maybe 15 minutes? It was still within an hour of me talking with them so not a big deal to me at all. I was thankful that they were able to get the job done at an affordable price. Looks like their service packages are priced right as well. Would definitely recommend to anyone that is looking for a fix on their a/c.”

“My A/C went out today and as a new homeowner I completely freaked out. I called another company and got the run around since it being after hours. I found your company online and took a chance. I’m so glad that I did. From the on call lady being so helpful and connecting me ASAP with your technician JR. He was very helpful, prompt, honest and knew exactly what was wrong. His customer service skills were AMAZING!!! Because of this experience I will definitely be using your company and referring all my friends to you. Thank you so much. 5 stars isn’t enough!!!”

“On a Saturday, my AC started to ice up because of a slow leak in the air handler unit(indoor) that takes a few years to reach this point after each service. Josh called me shortly after I contacted the main office and let me know when he’d be by to take a look. He arrived early and got straight to work diagnosing the issue I had shared with him, along with my systems history. After his inspection we discussed all the options and costs and I selected a refill option. There was no pressure, just facts, from Josh, which I appreciate. I recommend Josh and this company for anyone looking for emergency or routine maintenance!”
