“My water heater was spitting water! They were there within 5 minutes. They worked diligently, replaced it & stayed until everything was running properly. Truly impressed with professionalism & friendliness!“

“The price was high, but fair (we got other estimates). Their technicians were excellent (Elber, Eliseo, etc.). They worked a very long day and cleaned up beyond what I expected. Thanks, Higdon.“

“Zach was great and very efficient and the price was very reasonable. Thank you so much!!“

“Have used Environmental Comfort for 20+ years and they've always been top notch. Rick (the owner) is one of the best in the business. This year my Techs were Kyler, Jazz, and Zane. They were professional, respectful, knowledgeable, fast, and kind. I couldn't recommend a better business with a better set of highly skilled/qualified Techs.“

“Fantastic team eager to genuinely help and keep your home heated/cooled as needed. Same day assistance during a cold winter day when my heater wasn't working and got me fixed up in no time at all, fantastic company!“

“Excellent work. Friendly, helpful, knowledgeable. The right team to get the job done efficiently and within my budget. Always my first call if I need something fixed“

“This place is amazing and so is Steve!! He deserves a raise! Our AC has been out for a month and we couldn’t get anyone to come out here or answer our calls. Steve came out today and worked on our AC - even in the bad storms (seriously it was pouring rain and lightning at some points) but he worked through it. Will definitely use them again if we ever have any other issues. Thank you so much!!“

“These are the nicest people you will ever meet and their work is amazing!! They remolded our bathroom and it turned out way better than we ever expected. Thank you for everything you did for us and we are recommending you to everyone we know and come across!“

“I would highly recommend them to fix your air conditioning!!! They are on time, and very nice. If on Saturday or Sunday they will call on the way, and normally have the part or parts with them to fix your unit.“

“Synergy did an excellent job encapsulating the crawl space in my 115‑year‑old home. They removed an old vapor barrier and debris in a very tight space without making any mess in my basement. The encapsulation and spray foam work on the walls and pillars was exceptional. The crew was fast, efficient, and very professional. I highly recommend Todd, Will, and the entire Synergy team.“

“Eric and his staff are top notch. From the time I called explaining my issues, they were willing to help as soon as possible. A tech came out and tried fixing the issue but we ended up needing a full system replacement and they were able to get us a great deal on both an indoor and outdoor unit. Their pricing beat out a few other local companies that we got quotes from, beating some by $1000s. They understood being without air in Alabama during the month of June is not fun and got our replacements in just a couple of days. Golden and JT came out as early as they could the day of the replacement. They were very friendly and professional throughout the entire day. They uninstalled the old system and got the new system up and running in just a few hours.“

“Thanks for the great service and follow through with my HVAC challenges in our new church building.“

“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.“

“The team at A 2 Z exceeded my expectations in every way. The quality of the work is outstanding, and they went above and beyond to make sure every detail of my remodel was included in the project - even replacing the door hinges and knobs with hardware that matched my new fixtures! Their knowledge of every aspect of the remodel - from repairing the floor (the main reason the work was necessary) to updating the fixtures, plumbing, and electrical - was broad and deep. They communicated with me daily on the status of the project, and they provided me with a range of choices on materials, styles, and other options, which I greatly appreciated. I highly recommend this company to everyone!“
