I have a house built in 1960 and I needed to replace my thermostat. I decided to upgrade to a Nest device, and I was told I need a profession to install it. I called and they explained what they had to do (connect the smart thermostat to power). They came out on time, installed the Nest in less time than I anticipated, and stayed until it was completely set up. The guys were extremely nice and helpful. They even vacuumed the floor where they were working. Overall, great work. I will use them in the future for any HVAC needs. read more

I requested the A/C check prior to the summer season for use. The gentleman was very nice...went about checking the unit and the outside unit. I was pleased with his work. Will call him in November, to check the furnace for winter. The price is sort of "standard". read more

The service tech was very professional. Looked at my unit (attic, outside, thermostat) Gave me a quote and went on his way. I'm not sure if I'll use A-11 but the inspection went well. read more

Jose came out to replace the broken housings for two of our A/C units. He was on time, knowledgeable, very professional and did an excellent job. I learned he's been with the company for 14 years, which is remarkable in the HVAC business. Great company, great people. Highly recommend and thank you for doing a great job, Jose! read more

A 11 Air Conditioning came out to our home to check our system as one (Master Bedroom) was not cooling. We were told a part that tell the Compressor to come on was not working and needed to be replaced. Okay we had no problem with that or the cost that the repairman (Jose) quoted to us. The problem I find is with the three units of freon ( or current coolant used) put into the system. My copy of the repair slip says 3 lbs. of R-410A at 85.00 per unit put into the unit and no warranty due to existing leak. ( one unit was discounted per receipt) 1st of all our unit was cooling except one room. There was no mention of repair of the "existing leak", just put more coolant into the system. Why would you do that as it just going to leak out? Why not identify the leak, fix it and then put in freon? When I call the office to complain and express my concern today I spoke with Carlos who said he was the manager. His explanation to me was that it was common practice to add coolant with out seeing where the leak is or repairing it and then adding coolant. I disagree with the so called common practice as Mr. Carlos explained. He said we could call them next year and they will come out before summer to do a maintenance service. That is not going to happen as I do not trust them to do the right thing as I said to him. I would not recommend this company as I think they just padded the bill. I DO NOT THINK IT IS A REPUTABLE COMPANY. Also Mr. Jose was interested in selling us a new unit as he said the two units we have are too small. We have had this house over eleven year from original built and he is the only air conditioning serviceman to say our units are too small. I am telling you DO NOT USE THESE PEOPLE. read more

The A-11 crew arrived on time to replace our 2ton HVAC system. They had all of the new equipment and the tools needed for the job. They performed their job safely and professionally and I was pleased as I watched their attention to detail as they worked. The old equipment was promptly removed and the new equipment was readied for installation. The guys were very methodical in the handling of the equipment to ensure that nothing was damaged. They survived the heat of our attic as the new equipment was installed. The final installation looked great! I'm a picky homeowner and I was more than pleased with the quality of the work done. The price of our new HVAC system was very reasonable and competitive. I highly recommend the service of A-11 Air Conditioning Service. You won't be disappointed! read more

Our air con stopped cooling, then parts of the house lost electricity on a Friday night. Carlos the owner was great about calling me back and advising what to check for, what to do next. Oncor repaired the electrical issue and A11 came out early Sat to repair both air cons. Amazing professional service! One unit is over 10 years old and they fixed the issues (compressors) on both units at a great rate (under $400). This has been the 2nd time we've used them - 1st time was over 5 years ago and their service was consistent. Highly recommend! #lifesavers read more

I haven't had anything done yet,but the customer service is out of this world. Very professional and polite, that's a big plus for me, I can't wait for the very important process I think this is where I'm going so far so good. read more

They were super sketchy. The good - showed up on time and ultimately got the job done. The bad - tried to charge me $250 plus labor for a $14.00 part that was covered under warranty. When challenged on that point I got a long story about how they have to cover the cost of their new truck and shirts (??) and a suddenly very pissy attitude. Refused to provide any guarantee on their labor unless I bought an "extended warranty" from them. Charged significantly more than quoted from companies. I would not recommend and will never use again. read more

Had a new HVAC system installed in the attic from the original garage location and all new ducting as well. Carlos was quick to come give me a quote and his pricing were great. Got the job done in the predicted time and budget. Very happy with his service and integrity. Would recommend him to anyone looking for a good HVAC company. read more

My A/C went out on a Thursday evening. My son called this business at 7:30. Since one of the technicians lives close by, he came out. By 9:30 I had A/C again. I am elderly with health issues, so the heat is less tolerable for me than for younger people. Bless this business! Wonderful people and great work! read more

Hard working team excellent service, installed a unit in my house would recommend them. Also a guy named Jesus was a very good worker.

We have been using these guys for service calls for the last 6 years. Always on time, professional and charge a fair price. We have recently hired them for a big job - they replaced a furnace and repaired shoddy duct work that was done when our house was built in 2011. What a difference their work made! Our unit now runs quietly, only runs when it needs to as opposed to running "all the time". Not only have they fixed the issue at hand, but they also have made a great improvement in the heating/cooling efficiency of our house. It's been 2 months since they did this job and we still talk about them ("wow, what a difference they've made!"). HIGHLY RECOMMEND. read more

Couldn't tell me what was wrong with my a/c. Suggested 5 different possibilities and all were expensive. I need someone to pinpoint the issue so I don't waste time and money. read more

Carlos took care of my issue promptly. He was very thorough in his explanation. The appointment process was very easy.

Great service had a complete new unit installed. They were on time and crew was excellent very efficient staff came in and got the job done . Iam going to recommend them to anyone I know that needs a new unit . Owner Carlos was on point .Thank you. read more

Our AC went out on a Saturday night when temperatures were over 100 degrees during the day. I called A11 on Monday. By 3:00 they had come out and replaced the start relay for the compressor and we had air again. Carlos was wonderful. The charge was minimal. I am so grateful to A11. I will highly recommend them! read more

I used this company a couple of years ago . They came out , reset the unit for a very resonable service call . I just had them replace my compressor unit . Fast and honest . They will be my go to HAVC company . read more

Came out when they said they would and got my air conditioner running again. What more can you ask for.

Carlos responded quickly and had a technician to trouble shoot my heater within 90 minutes. Jose was knowledgeable, kind and efficient. Didn't try to upsell me on anything and just resolved the issue so we could relax knowing all was working well. Will definitely use again. read more

This is the sort of place that you want to talk to when you have an A/C problem. A-11 was honest, forthright, respectful and professional. Perhaps most importantly: They were lightning fast. They did not use any high-pressure sales techniques, listened to my issue, provided me with a detailed diagnosis and multiple options to fix the problem. They answered my service call in under 2 hours on a hot summer afternoon. They had an entirely new unit, inside and out, installed in under 6 hours the next morning for less than half the price of a competing estimate, with a handsome warranty and free wifi thermostat included. This is the type of professional and quality customer service experience I wish I could have with every vendor I use. They look you in the eye and tell you the truth. They value your business and work with you on what your best options are. They do not try to up sell you. They also provide high quality work. After they left you would not even know they were here; no cleanup on our end required, the interior work was incredibly quiet, quick and solid. I'd recommend these guys to anyone. read more

Excellent service!! They cleaned and serviced our air conditioner. The tech was friendly and very thorough. Their service charge was more reasonable than anyone we've used in the past. We will definitely be using them in the future! read more

Our AC went out late on a week night and we can all agree that summer nights in TX would be miserable w/o an AC. I reached out to a few AC repair businesses and did not have any luck until I came across A-11. They were professional, prompt and quick to service or AC. I would definitely recommend A-11 to friends and family. read more

For starters, the tech showed up 30 minutes early instead of 2 hours late. He was courteous, knowledgeable and efficient. Best of all, they are aggressively priced. Highly recommended. read more

Perfect experience! I requested quotes for getting a new A/C installed at my house. Yelp sent 5 messages to different companies, most of them replied very quickly. I wasn't reallu interested in wasting my time, nor others so I requested that they give me a quote before coming onsite. I was fully ware that once they came onsite the price could change, even dramatically, but I wanted to week out that were already way outside the other quotes. Most of them pushed back, a couple eventually wavered and gave me the quote after insisting they could not do so without coming onsite first, which I declines. A-11 not only didn't push back on delivering a quote, they did so quite quickly, after asking a few basic questions which I would expect no less than. After determining that their estimate was a good chunk less than the other responders I invited them to come onsite to do an assessment and provide a formal quote. They came out the same day, and unlike some of the other responders, did not request any fees or charges to do this. After looking around for a bit they said they would put something together as far as a quote and get back to us. They did so later that day and the price was right around the original estimate. The price however, was a good bit cheaper than the other responders, and most of the other responders were fairly close to each other so I had a decent bit of skepticism. We provided the estimate and description to a local AC businessman who is very highly rated in the area and he said it was good equipment and he had no idea how they were able to offer the install for that price. We decided to proceed. A-11 came in and stated it would take 6-8 hours. They showed up on time and began working immediately. They actually finished in just under 4 hours, and offered to do a walk through of what was done. I'm not an expert, but everything looked really good to me, granted, our other unit is very old and not in great shape, but still, the new unit looked great. They seemed to follow all COVID19 safety protocols, they were masks. There were nothing to clean up after they left as far as I could see. I didn't want to write a review until the A/C had been running for awhile. It's been about a month and so far, absolutely zero issues. Our NEST even shows much lower run times after the unit was replaced. Some of that was weather related but I have been watching it and feel it did indeed drop. I would definitely recommend A-11 to others, and I will definitely be having them replace our upstairs unit in the very near future. read more

Called when my A/C was acting up. Within a few hours I had a technician on site. He found a bad capacitor and it was quickly replaced. Pleasant interaction and would recommend to anyone looking for service or annual maintenance! read more

My A/C went out last night (a Friday). A-11 came on Saturday, service fee was the best quoted, and Jose explained and showed me everything that was wrong with my unit. I did my research and knew what price range to expect and A-11 was at the lower end of that range. Jose did an excellent job and I'm enjoying my cool house again. Reliable, reasonable and friendly. My choice for future projects. read more

Great experience. Showed up on time, fixed the problem quick and ac was up and running. Very polite tech!! Thank you for saving my weekend!! read more

I live in a duplex and I have been telling my landlord that there is something wrong with my A/C. I decided to take measures I to my own hand, I called this company about 10 minutes ago to get a quote to see how much they would charge to come and diagnose what may be going on with my A/C. I explained to him that it is currently 80 degrees in my place. I explained to him the issues that I'm having with my landlord and that I wanted to pay to find out what the problem is. He began to explain that across America people have lost cell phone service, he is extremely business and to contact my landlord. His phone rang and he told me he had to go. Here I am trying to higher his company for a service and he told me he had to go when his phone rang. I wouldn't recommend during business with them. read more

Very professional, had new HVAC system installed. Addressed additional problems we were having with air flow between the bedrooms. Rerouted a couple ducts & problem solved. Very patient and explained various options and maintenance for the new system. read more

We're very easy to work with, responsive, courteous, competitive pricing. Quick install, they send before and after pictures since I'm not in the area and registered the unit with the manufacturer. read more

The of the worst things that can happen in Texas is for your air conditioning to go out. This happened to my bro who doesn't write reviews but I'm an eyewitness to the whole incident. My brother was referred to another company and they came out did all the checks and said he needed to replace his indoor and outdoor units. He's been in his home for 17 years and the system was there when he bought the place. He was quoted a price for a top of the line Carrier unit and another model that Carrier manufacturers for a few hundred dollars less and he was all set to go with that until speaking with a friend who recommended A-11. It's always good to get a second opinion because of course he would with a doctor. He called Carlos with A-11, and a few days later and he came out gave it a full check with the same result, new units in and outside. Carlos quoted the for the same Carrier unit at half the price of the first company. He said he believes it's better to have more customers because he's not out to get rich. He also stated they get most of their business by word of mouth. It's so nice to do business with a company that believes in honesty. They were also very professional; they set up a time, arrived on time and completed the work within the time they quoted. An issue came up with the breakers that were installed with his previous units and his water heater. His indoor unit and his water heater were installed on the same breaker. Carlos suggest they be separated for safety (our cousin is a licensed electrician and after a confirmation call with him) my brother picked up the breakers and Carlos changed them at no additional charge. My brother's air was running smoothly within a few hours and it looked like no one had ever been there. A job well done at a fair price. read more

Was going to give A11 a rating of 5. They came out, gave us a quote for a new hvac unit cash pricing. Not only a better unit but priced less than others. They did an excellent job installing the unit. We called them back to install new ac ducting. Near end of job, noticed a foot hole thru our living room ceiling. We immediately showed them. The 2 workers, after speaking to each other, came back, stated it was water damage, not their fault and left. This is clearly a foot thru the ceiling, between and off of the rafters where you aren't supposed to walk! There is no sign of current or previous water damage at that location. I would have been ok with " we are so sorry, what can we do to make this right?" They just left. We do have a little water damage in another part of the room which the insurance company is already fixing and it is contained and not in any other part of the room. So this new damage is from someone stepping where they shouldnt, not from anything else. read more
