HVAC reviews in Marietta, Georgia

Curtis was amazing. He took his time checked and double checked to ensure that our leak was fixed. Spent extra time on our older system to ensure a solid fix. Professional, courteous and kind working well beyond 5pm.

Excellent service from Sam’s diagnosis to Michael’s explanation of options to Zach and Michael’s hard work on installation. I trust Casteel with repairs, design, maintenance and, in this case, replacement. They answered the phone at 6am to set up an 8am visit. Remarkable and outstanding!

Really good experience using these guys to replace. I live in an older home and have been having problems with my HVAC for years- after trying different companies to come out for service with no avail or diagnosis I called Casteel. Unfortunately my system was close to failure, but thanks to Steve (maintence dept) and Michael (design team) I had the new system installed promptly even though it was the day before Thanksgiving. I feel like the employees of this company really do care about customer satisfaction and are great at communicating and answering any questions you may have. I would hire Casteel again without hesitation.

Javier couldn’t have been better.

Took a couple trips as he needed to order a part for a unique shower fixture , but he came back the day it arrived and fixed an issue that two other teams had failed to find.

Talked me through each item and was up front with the costs for each piece.

Absolutely perfect !

Brandon R. came to service our furnace, and I greatly appreciate the time he spent explaining everything to me. He made recommendations on things we should consider, but didn’t try to oversell anything to us - which I appreciate. He was efficient and thorough in his work.

My experience was great.My technician, Mr. Land was so nice and helpful! He helped me find the right kind of faucet and installed it in no time. He knew exactly what he was doing! I would highly recommend him to anyone who has plumbing issues.

Had low pressure issues in the upstairs bathroom. Was able to schedule an appointment online and get a tech to come out very quickly. Kevin fixed the problem quickly and was also able to answer all my questions about possible water heater replacements/upgrades. Thanks for the great service!

My service technician, Daniel Wiggins, was awesome. He was on time, very friendly and took the time to explain the issues with my HVAC system and well as repair options. I appreciated his honesty and willingness to help. Thanks Casteel!

Wow, wow, wow. Samuel was my technician and let me tell you -- the BEST customer experience I've ever had. My CO sensor went off and I scheduled an appointment in a panic. The scheduling process was super easy, Samuel showed up ON TIME and thoroughly checked all of my units. Not only did he find several cracks in my furnace, he showed me moldy growth that had grown on my other unit that needed to be addressed. He answered all my questions, took video, and showed me every single thing. He was kind, thoughtful, honest and direct with his recommendations.

In addition, my husband was out of town for work she he took extra care in making sure I knew where things were so I could feel safe with my girls in the house. I signed up for their membership and support program on the spot. Thank you Samuel!!

Michael and Jake Cepeda and one other person whose name I don't remember were punctual, professional, personable, and knowledgeable. All information about the furnace that I purchased including warranty, pricing, maintenance, etc. was thoroughly explained to m satisfaction. I was also given written information to back up everything that was presented to me. All three men did an excellent job.

An unexpectedly exceptional experience from the call to Jason solving my issue. I called at 3:50 pm expecting to be told that I could have a technician out in a few days and certainly the earliest being tmrw with temps having dropped in Atl overnight to the 20s/30s. By 4:30, Jason was ringing my doorbell and by 5:15, the repair was complete. I’m still in shock! The person I spoke with was also so pleasant, helpful and accommodating. Masterclass in customer service! Customer for life!!

David and Aiden, my technicians, were absolutely great! Even on New Year's evening they were so lovely and went above and beyond to take care of me -- even beyond the initial needs I requested. My dogs loved them! I can't say enough good things. I'm so appreciative of Casteel, as the phenomenal company that it always is. I was not aware they did electrical until I was googling looking for someone and was relieved to find they offered the service. Use this trusted company for this and any other need. They even came in the FIRST hour of the four hour window!

Matthew was very professional and informative took us through the issues with our electric system. He explained everything in detail and walked us through all repair option with no pressure to purchase a specific option. He comforted us and made sure we knew, that we and our home were safe and what was needed to get our home in it's best shape for the future. Thank you Matthew for your magnificent work and Thank you Casteel for having this knowledgeable and professional person on your team. My husband and I are grateful.

I had an absolutely wonderful experience with Samuel, my HVAC technician. From the moment he arrived, he was incredibly kind, professional, and patient. He took the time to explain everything to me in a way that was easy to understand, never rushing through the details or making me feel unsure. It’s rare to meet someone who is not only highly knowledgeable but also genuinely cares about making sure you feel comfortable and informed.

Samuel’s work and recommendations were thorough, efficient, and clearly done with honesty. I truly appreciated his kindness throughout the entire visit — it made all the difference. I’m a new homeowner, so naturally nervous and not knowledgeable in these areas, but Samual literally gave me an HVAC 101 lesson! Most of all, he was straight forward and honest on what condition my system was in and what the best steps were for me.

I highly recommend Samuel and will absolutely be requesting him for any future HVAC needs with Casteel!

Donald came out to look at our hot water heater that wasn’t working. He was amazing! His overview of the equipment was very detailed, and he even showed me a small leak we didn’t even know we had. He cleaned up the old piping and as he said, “to make it look pretty”. I would highly recommend Casteel and Donald to friends.

I had a great experience with Casteel Heating, Cooling & Plumbing. Justin T. installed a new toilet for me, and he was fantastic from start to finish. He was kind, professional, and took the time to explain every step of the process so I knew exactly what to expect. The installation was done efficiently, and he made sure the area was completely clean before he left. I really appreciate the quality of service and care—highly recommend both Justin T. and Casteel!

Customer Service
Their superior customer service is unmatched. Their customer service is the Chick-Fil-A of the HVAC industry. Each rep that dispatches wears shoe covers. The flexibility of their scheduling is unrivaled. We have never seen anything like it. A service technician dispatched late one evening. On another day, a sales system designer dispatched ON A SUNDAY. . . . AT 6PM!!! We were enthralled and are impressed by that. That is unprecedented.

Technician
They dispatched one of their service techs, Ron, to troubleshoot our inoperable furnace. He diagnosed and resolved our issue without incident (i.e. He worked safely; thank goodness). He cleaned up good and re-assembled everything he took apart. He also explained everything to us in a manner we understood.

Sales Designer
This guy, Chris Meitzler, dispatched to our home at 6pm on a Sunday, which, as stated earlier, is mind-blowingly unprecedented, but we greatly appreciate it. Our schedules are irregular, unusual, and unpredictable. We prefer to meet during usual business hours to make it easy on the company dispatching to our home, but sometimes, we just cannot swing it. Casteel accommodated us without complaint.

Chris gave us options without pigeonholing us to make the most expensive purchase. He thoroughly explained each option.

Their people we've meet thus far are personable and relatable. . . people you could sit on the porch with and share experiences or have a few drinks and laughs over a football game. You can tell they're genuine, good-natured people who enjoy their profession and enjoy taking care of people.

That does it for us! Casteel is going to be our new HVAC provider! We're excited!

I am extremely disappointed with the service today. The tech showed up and immediately told me that since there was a repair last year his recommendation was a full replacement. I let him know real fast that was not happening and it went downhill from there. In the middle of the job, had to leave and get additional parts. He was gone almost an hour and half. When he finished, he told me that we needed to put sand out there but I had no clue what he was talking about. The tech left the hole open with the plumbing pipe exposed. If I am paying almost 1,000.00, my expectation is for it to be completed. I had someone out here a year ago and he did an amazing job. He didn’t leave the job undone. I called to complain but the representative advised that they are out of the office until Monday. I have attached pictures of what the repair looks like now that he is gone.

Jamie was awesome! I called Casteel to see if they could come out and give us a quote on a water heater replacement. He went above and beyond to explain everything in great detail without me even asking and also gladly answered additional questions that I had. He didn’t just explain, he showed me what he was talking about and now I feel like I received a crash course in plumbing and heating :) Professional and courteous, offered discounts when I told him we probably wouldn’t be able to afford the replacement at the moment. Would recommend to others.

Deandre was my technician today and he absolutely exceeded my expectations! He was courteous and very professional as well as knowledgeable to determine the electrical issues that I was experiencing. He did an excellent job diagnosing the issue, thoroughly explaining the issue and the resolution process. If I ever have additional electrical issues, I would absolutely request Deandre again to be my technician! Excellent job and thank you so very much! A happy customer!!

Ryan and Trey were fantastic! They came out 2 days back to back to put in a whole new heating and air system. They explained everything very precisely. Very professional with their work, very clean and very understanding! They worked fast, but also made sure everything was working how it should be!
Highly recommended these men!
