We have used ATOZ for a number of years for everything from repairs to ice makers, commercial refrigerators and freezers to repairs on existing a/c units and installation of new units. They have been out first thing in the morning and late at night. We’ve never had a problem with David or Albert and would highly recommend them for a/c, heating, and refrigeration needs.

Mr. Erwin fixed our commercial ice machine in no time at all! We had a hard time locating someone that would work on it and finally found someone that did a great job! Would definitely recommend him for your job large or small!

I was lucky enough to be referred to David by a coworker when my AC went out during a heat wave. He was prompt and very helpful, coming by and fixing the problem the same day. I would highly recommend them for all your AC needs!

My AC went out and I had called another place first, but they couldn’t come out til the next day. So I found A to Z and boy that was the best call! David answered right away and was very polite and was at my house within 5 minutes. He was fast and professional. Unlike other repair men, David came prepared by having AC parts on him so didn’t have to wait to order anything! Within the hour, he had it back up and running and when you live in Texas, AC is a necessity! I recommend A to Z over anyone in Seguin to come out that day and fix your problem. And not only was he fast and very knowledgeable about his job but he was very reasonable as well! We definitely found us a new AC repair man. Don’t take my word, call for yourself and you won’t be disappointed.

David and his crew were awesome. We noticed our AC was acting funny over night. Called him at 7:30 am, he was by 10am (totally understand he squeezed us in). Our AC was on it way out, he got ours to work to get us through the nigh, was at our house at 7:30 the next morning. Very nice, professional, just overall a great team. Called later on in the day to make sure all was working. While in my house they made sure to clean up any messes and left their work area better then they found it. Highly recommend! Very happy!

If you need any repairs, these are the guys! I regret not calling them first! I was without AC for 21 days! David and his team made one trip, confirmed the problem, got the parts and we are cooled off! Wish I could give them 10 stars!!!

I called AtoZ on Saturday evening. They answered and made it out on Sunday morning. They were quick, and fixed the problem with our deli cooler (burnt out motor) in about an hour or so. They had a motor on hand. I was very pleased. SHOWED UP ON A SUNDAY!!! Thank you, David.

AtoZ is a fantastic company! They have helped me several times with my Air Condition Unit and Thermostat! AtoZ has always been able to quickly and accurately diagnose the issue and fix it straight away. Atoz has always been able to service my unit the same day I have reached out! I would highly recommend them for business :)
