Unfortunately, he was unable to fix the issue, no worries we told him we had Home Warranty and they'd send someone out on Monday. We just didn't want to wait the whole weekend if it was a simple fix. Fast forward to Monday, the HW contractor came out and wouldn't touch the unit bc GAC hadn't put it back together after diagnosis. Well, it's against HW policy to touch it if it's been tampered with. No big deal, right? Surely GAC would be happy to come put it back on since I had paid him $85 to do nothing on Saturday, right? NO! I was blamed for not telling him I had a home warranty, WHICH I DID! He even WROTE IT ON THE INVOICE!!!!! I was obviously upset and taken by surprise to hear this, so I told him he 'wrote it on the f'g invoice' and this grown man said I cursed him out and he'd rather rip up my check than help me. Thanks to this no good jerk my HW was void, and my family...including a 2 year old...is once again without air. Oh, did I mention that when the HW tech came he said it was an EASY FIX that his 13 year old son could repair?! And GAC quoted me $800 for a new computer. Thanks for nothing!

The thermostat was reading 98 degrees in the living room. Called our regular AC company only to get an answering machine so I Called C.A.S. which is local and explained our situation. They had a technician at my house within 30 minutes. After checking my AC unit and determing it had plenty of Freon, he went up into the attic and found recently replaced Duckwork (by anothet AC company) had slipped off of the AC unit in the attic which was causing our AC not to cool the house. He indicated the new duckwork installed last year was too short and the installer had stretched it to the max which eventually caused the duckwork to seperate from the AC unit. He replaced about 6 ft of Duckwork, cleaned the grill on the outside AC unit and we were back in business with nice cool air

We had to deal with a lot of salesmen-y type of people that didn't feel honest. Quoting huge numbers and telling us our AC was definitely going to die any moment. Telling us we had to buy these huge expensive replacements. We knew it was going bad, but the experience we had with the greasy salesmen techs made us decide to wait for it to fail before trying again to find someone good. It finally failed May 2026. I did my research again and found this company. The reviews were great but I was still really nervous because of our last experience. Called them out, fully expecting to go through the process of calling multiple people before finding someone. However, Alfredo was immediately different from the others. He is such a kind and personable person. What a great first impression. If you are able to ask by name, I suggest ask for Alfredo. He arrived exactly on time, too. He didn't feel like a salesperson at all. He felt honest and genuine. He gave us all of our options. From repair to full and complete replacement and everything in between. He discussed with us the pros and cons of each option. It never felt like he was pushing us one way or the other. It felt like he just wanted us to have a working AC that worked for us, period. He also spoke equally to both my husband and I. Many technicians tend to only speak to my husband which is annoying since I take care of most of the home management. Previously we were told we had to do this super expensive option to keep our upstairs cool but Alfredo told us we likely didn't need it, and if we did, we could have it added later. I knew right away we didn't need to have anyone else come out. We chose them and they were able to install our new system same day. We left the house, and they were very respectful of our house while they were here alone. They cleaned up after themselves and locked the doors behind them. He said they would likely be done around 2am and they finished at exactly 1:59am! We had a Lego display on the wall that I'm guessing got bumped (I forgot to remove it before they arrived so that was my bad). Some pieces fell off and broke apart and they put them all on the table. I've knocked that thing off myself and finding those scattered pieces is annoying. No missing pieces at all. I was impressed by this small thing. Just another example of the care and thoughtfulness of the crew. The AC is incredible. I'm very happy so far with our choice in system and in who we picked to install it. I don't feel bamboozled or taken advantage of in any way. Highly recommend! Very glad I found them.
