"A+ service and work. My home warranty refused to hold up their side of the bargain and we were forced to find a water heater we could afford and were lucky to find American Service Specialists! They gave us the best quote by 400 dollars and did quality work. This allowed us to get a spigot (which was also the best price I have received on it) installed!  They are now our plumbers for as long as we may live here in Georgia! And we have gone through a few here so we are happy to have one more professional we can call on when needed!

"I had trouble with the AC about a month after they did an annual service and replaced the capacitor. The system locked up and they came out and I watched as they pulled an obviously old, worn, and burnt, electrical part out next. They replaced that part for the cost of the part and waived the labor as it was so close to the last service. The system is old and they were finding parts that were reaching the end of their life and replacing rather than trying to sell me a whole new system but let me know they would be there if I decided I needed a new system. Fast service, pleasant and knowledgeable personnel."

"The entire process was great from start to finish! Ashley and Josh did a wonderful job helping me get everything set up. Brian and Brent helped me understand my options and beat the local competitors offer. Josh, Izaac, and Nick did an amazing job installing my new system. They worked quickly and quietly and left no mess behind. Everyone was so polite and professional. I highly recommend TE!"

Customers say: Super punctual

"Appointment setting is always easy and quick. They even called on Sunday to offer to come a day early. Kyle McGuire has clearly earned his Certified Master Plumber - listened to concerns and got quickly to work with great results, restoring our in-home water pressure."

"Last year (2021), I hired Casteel to upgrade my HVAC system, tankless water heater, update the pipes in my basement, install a pump for washing machine and bring my electricity. I have a brink home the was built in 1955 and had not had any major repairs since 1985. Everyone I spoke to during the process of consulting and repair was professional, kind and courteous. They always kept an open line of communication and were willing to adjust their schedule according to emergency circumstances that happened in my family. From the products they used to the quality of the workmanship, I am still very pleased with outcome. They respected not only my time but my property too. I will definitely hire them again. I highly recommend them to anyone in the Atlanta, GA area."
