Reviews frequently mention fast response and technicians who communicate clearly about the problem and fix. Many note professional, respectful crews and smooth full-system replacements with fair pricing. Scheduling flexibility for organizations like churches is highlighted. A small number of reviews cite delays on follow-up repairs, but most describe consistently reliable service.

I called Southeastern Mechanical Services today around 2pm because I was having an issue with my AC not working and they came right out and fixed the issue! Andy, who was the tech, was amazing! So professional! Very easy to talk to and he was very informative about what the problem was and how he fixed it! I am going to use this Company for ALL of my AC needs!!! Check them out! WOW

SMS has gone above and beyond servicing our church units. They respond quickly and are extremely accommodating with scheduling around having a staff members being present - which can be tough at a church. Their techs are all CERTIFIED which is extremely rare and difficult to find. Their guys have all been extremely respectful, friendly and knowledgeable.

Southeastern Mechanical Services had competitive pricing compared to larger companies we received bids from and are careful to make sure they don't sell us something we don’t need but thoroughly explain issues we have had.

They always make sure to give us all the options on how to proceed and their professional recommendation isn’t always the one with the largest dollar amount attached to it. Thank you SMS for your dedication to your customers, service and to your community! I respect you guys as a company and as individuals. I appreciate all you do not just for us but for what we see your company do in the community also. I love being able to hire a locally owned business that does GREAT work.

With SMS this experience could have been a horror story. They responded very quickly with the right unit, the right price, the right crew, the right results. For an emergency or regular need for service on AC issues, we would recommend these folks quickly.
Friendly, professional, punctual, skilled, and keeps you informed on progress.

An outstanding experience with SMS. My old system was unreliable at best and needed to be replaced.I Contacted SMS, who gave me a very reasonable and detailed quote. I decided to have the entire HVAC system replaced. They scheduled me in and got the work done. The install crew was top notch, hard working and took their time to do it right. I couldn’t ask for better. This company goes above and beyond to ensure the best quality work is done. I highly recommend SMS.

my hvac system which they put in by the way, stopped working in February, I’ve called them 5 times since then to fix the Freon leak. It’s 76 degrees in my house right now after he told me in august he’d be back to fix it on the following Monday I didn’t have to be here. Well apparently he didn’t come back and fix the leak.
Also they told me 2 months ago that they couldn’t come out because they were booked up for two weeks, that call another HVAC company which I did. He told me it had a leak he put 4 pounds of Freon in it. Then they told me the guy that worked on my unit in February had quit. They are now saying they are booked up again for 2 weeks. Well I ask her in July 3 times to set up a maintenance plan and they could come back this month to clean the unit before cold sets in. She never set it up,
