Alief Ultra Mechanical- Air Conditioning and Heating

We used them last year for a new Trane and they were great. They did an excellent job protecting our home and the AC works great. Today we called for a service call on an older Trane and they sent a 20 year employee. He got us back up and running for a very reasonable service call. These guys are trustworthy and the kind of people you want working on you home.

Alief Air has been looking after our a/c since we moved to Houston in 1992. They have come quickly in rain storms and blistering heat. They have rescued us time and again when lightening fried the condenser in the a/c. They have always been honest with us - looking for the cheaper alternative when we were prepared for the worst. Mike is knowledgeable and friendly and we recommend Alief Air without reservation of any kind. When the time comes for us to sell this house and move into the old folks home, we will leave an Alief Air card taped to the kitchen cabinet right where we found one 26 years ago. Thanks, Mike!

We have our main house and a one story rental house for investment purposes. We have asked Alief Heating and Air Conditioning to install new units in both houses. Their work has always been fast, cost effective and excellent. When they say they are coming, they arrive on time. We always feel we can leave the house and it is safe to do so with the Alief people there. We have also had some emergencies with heat on very cold days and air conditioning on very hot days. If I call Alief, they can always find the time in their very busy schedule to arrive and make sure our systems are in good working order. They also provided 0% financing, provided that we pay on time. Alief is wonderful. No question.

Mike and the team at Alief did a wonderful job of replacing and updating our HVAC system. Mike came to the rescue once with a AC problem in the middle of the summer, to my family's relief. From then on he earned my trust and service. When the time came to replace our system, Alief provided the most thorough and competitive bid along with the dependability of Trane. We could not be happier to have a business like Alief close and they will always be our go to.

Mike and his team at Alief Heating & Air have serviced and supplied HVAC systems for two of our family's generations, well over 25 years. We completely trust his advice and know that all work will be performed professionally. His operation is unique, a family business, one we gladly support and recommend!

I have known Mike, the owner, for more than 30 years. He shoots straight and he knows his business. He cares how the customer feels. He recommends high quality ac and heating systems. He put in both of mine and my parents systems, too. He and his employees are the very best in what they do. They are always my first choice. Thank you, Mike, for being the very best! J.B.

This company has the BEST staff and work ethics you will ever find. Mr. Mike is great on listening to any issue you are having and try to determine what it may be. Mr. John has been the actual tech that comes out to work on my units. They have been doing the maintenance on my Trane unit since 2010. They truly try to work on your schedule. The original Trane unit I had was a 1993 model. It finally gave out in 2016. I had a warranty company check it out and never come back, well I called Mr. Mike, he gave me 3 different unit sizes, costs and installation dates. 4 days later which was on a Saturday, the crew came out, replaced all of the A/C unit. I got a better and more energy efficient Trane. I'm happy the warranty company didn't come back(which I cancelled) because the new Trane works terrific. Mr. Mike and his staff provides quality products, TERRIFIC customer service, and honest quotes with honest staff. I will not look to any other company. I live in Katy, but they service all over Houston. Thanks for being the BEST at what you do for your customers!! 😊👍

As I was home during the day more during the summer, I noticed my a/c ran continually, and my house was never cool. At first I thought it was just the summer heat, but when I got my June electric bill, I knew I had a problem. I called Alief Heating and Air Conditioning and explained my dilemma. Although the lady explained they were completely booked, she told me she would call a tech and see if they could fit me in. I was thrilled when a tech, John, called me back and explained that he was in my neighborhood and could come by that afternoon and at least try to diagnose the problem. I was glad they would be able to get to it that quickly!

When John came, he spent a lot of time in the attic and found the problem. Luckily he had the part on his truck and was able to fix it right then and there!!!! I was so relieved!!! He also said he wanted to check the outside unit to make sure it was working efficiently and that the freon level was correct. I was glad to have the entire system inspected, not just the found problem fixed!

To top it off, the total charge was less than I ever expected! After John spent the time to explain to me the problem, fix it, and inspect the rest of the system, I feared the bill would be astronomical. But it was more than fair, and they did not charge me for having to fit me in!

I will definitely call Alief Heating and Air when its time to repair or (ugh!) replace my unit! The efficiency, service tech, and pricing I received convinced me of that!!!!!

Our neighbors recommended Alief Air Conditioning when we woke up on a Friday morning in August and our downstairs air wasn’t working. We called and were told they were booked but would try. Good news they called back a few hours later and said they could come over. Best part, the fix was less than $200! Will be calling Alief Air for all our air and heating needs.

Came out to clients property told him everything was fine with the AC and is in working condition, then lies in his report bc he works for the other peoples clients and putting words in my clients mouth...such as the AC breaks down once a year etc etc. This is by far the most unethical company I have ever worked with I will be filing a complaint against their license with the state of Texas. Tech name was Mike had another AC guy come out and confirm everything was fine. Don't use this company under any circumstances!!!!!
