Our experience with Mark and John of GB Services was amazing. Mark and John first visited the house when we were experiencing issues with high humidity in the house. Instead of providing a generic quote for resolving our issues, he actually waited to researched the issue to determine what solution would be best for us. Mark and John both make tremendous efforts to clearly explain what the conditions are, how the equipment is operating and how the solution will work. They made me feel like their number one customer and from day one, I knew I was in good hands. I never felt rushed or pressured or inconvenienced- they want to inform and educate their customers, not just sell a product and disappear. After determining the best solution, Mark scheduled our service date quickly and was always available by phone and email for questions. Before the date of service arrived, I had questions about additional work that needed to be done and Mark promptly provided quotes for work and scheduled them for the same day. All pricing was competitive and I felt confident with Mark and John's abilities to install new equipment correctly and correct issues with existing equipment that needed replacement or servicing or was installed incorrectly. When the date of service arrived, Mark and John arrived on-time and stayed until the job was complete. I could not be happier with the installation! John told me his work is his passion- and it shows! They reworked our entire setup to make our air conditioning better functioning and more easily serviced. They even stopped by our house two additional times to make sure everything was running correctly - at no additional charge! I am so excited to have found GB Services. They did amazing work at our house - everything looks great and works great- it's such an improvement!. I will gladly call Mark and John with any future needs and with their unsurpassed craftsmanship and competitive pricing- I know I'm getting the best! Look no further than GB Services for your AC needs. I gladly give them my highest recommendation without any reservation. read more

If you are looking for and HVAC company - just go ahead and stop your search. I will never use another HVAC company ever again. Their workmanship really is that good. I was connected with GB Services by a good friend in the HVAC industry. He has grown up in the HVAC industry and when I planned on getting a new system installed he sent GB. He knew they would do great work and I must say that he was right. Everything about my experience was exceptional. There are a few qualities that make them great: Honesty - The GB Services team will shoot you straight. They'll assess your situation and tell you what you REALLY need not what will pad their accounts. They'll suggest options with the best pay back and those that are appropriate for your situation. They are truly genuine and gentlemen. Integrity - During the process they found a gas leak in my basement. It wasn't their work, but Mark came back to my house at 6:30 pm on a Friday night to make sure that the situation was addressed. It take integrity to put your customer and their safety first regardless of convenience. Pride - When they do their work you can rest assured knowing that they are going to do it right the first time. Not just "right", but "right" to the extreme. The ductwork and installation of all units was done with extreme care and planning. They took the time to really plan it out and ensure that airflow would be as close to perfect as possible. The installations are very clean and you can tell that they take pride in every step of the process. I'll be transitioning the service of all my Atlanta based properties to the GB Services team from here forward. Just use these guys - you won't regret it. read more

Our experience with GB services could not be better (except if we had not had any issues at all). We Contacted Mark for the first time 1 week after moving into a recently purchased foreclosure. One of our two units was completely off. Within minutes, Mark had figured out the drainage pipe was incorretly configured and had it fixed 5 minutes later. It was as painless as could be, almost. Mark also pointed out, while testing which unit was which, that our other was out of coolant. He refilled it and warned us it may be an issue. He also worked with us to register our two units for warranty (even though we didn't even have internet configured at the house yet). Two weeks later we were once again out of coolant and had to call Mark again. He had to do a line test and found out it was faulty hardware. He then worked with the manafacturer to fix it. He has checked on us after to make sure things are working correctly, and has worked around our schedule. I don't normally write a lot of reviews, but I really like the service and attitude Mark has. Not only did he quickly resolve issues, but he did so while informing us of everything going on and never making us feel inadequate or misinformed. I cannot recommend GB services enough. Great Job Mark. read more

I did not want to indicate 'any' stars, as GB Services never serviced me. If you want to know why, read on. Based on the reviews on Yelp, I determined that GB Services was the best choice, so I called them and was asked where we live. It appears they only work in between the 'arc' of I-85 and I-75, however, we are about 1 1/5 mile north of I-285, and that was too far away. OK, I understand you want to give great customer service within a specific range, no problem. Meanwhile, I still needed service and a new system and since the reviews were so good, I asked if I could speak to the manager/owner and if he could refer me to another company that had equally good standards and reports. I left my name and number though the 'response' I received was not that friendly - and you may have guessed it - that the owner/manager never called. Providing excellent customer service is one important aspect of running your business, protecting your brand and reputation another and an important part of that equation. I can not say anything bad or negative about GB Services, though would suggest that a brief follow up call would have not only been courteous, it also would have been appropriate. read more

Great Customer Service! I absolutely recommend Mark for his professional installation and complete follow through with high level of service after. I also recommend the Carrier system that Mark installed in my condo - I have a multi-stage system. Extremely quiet and efficient - perfect for a condo where the unit is located in a space near the living area. Also - I absolutely recommend the smart thermostat that Mark installs. I was not able to keep my Nest due to the thermostat having to communicate on the proprietary communication link to the system. However, that paid off this summer when my unit experienced a problem. I was in on vacation (in Paris) when my system sent me an error code alert. I sent Mark an email asking if I should be concerned (from Paris) - he immediately responded asking me if I could turn off the system remotely. I did (from Paris). He asked when he could gain access - I contacted my building security to allow access (from Paris) and he came in the next day to repair. All communication from a café in Paris! All under warranty. I came home to a 72 degree condo vs 90 degree and broken unit. Great - Great - Great read more

I recently bought a condo unit. Before the purchase, the HVAC system was not responding to calls from the thermostat. This issue had been repaired by the previous owner, and the fix lasted for about 4 weeks after I moved in. When I called the company that did the original work, All-County Inc., they told me they were "too busy to take new jobs," even though the job I had was for them to fix their shoddy workmanship! That's when I called GB Services. Their staff were very professional, polite, and prompt in returning my phone calls. They were excellent about setting up a time that worked with my schedule. John Molina, the technician who did the repairs, was able to expertly deduce not only what the underlying issue with my HVAC system was, but was able to figure out where the All-County Inc. had gone wrong. He showed me what the problems were, and fixed them efficiently. He also pointed out a problem with my natural gas system that had gone unnoticed. I would recommend GB Services to anybody and everybody, and will ask them to come back for all my HVAC needs. read more

GB Services installed a dehumidifier on our main unit and an A/C and dehumidifier in our basement. We couldn't be any happier with the level of service, product and install. Mark took the time to explain everything prior to installation, they were on-site when promised and took about the amount they projected. The team left the area clean and Mark stopped by for a follow-up inspection to verify the install was performed correctly. There was no hidden cost and was almost exactly what we were quoted. Lastly, they were always available for all of our questions after the install. It's now 9 months later and there have been no problems with the product or the installation. The dehumidifiers have us living comfortable and the basement feels so much like part of the regular living space we leave the door between the basement and the main floor open 24 hours a day (1974 house). We recommend using GB Services for HVAC repairs, install and for standard HVAC maintenance services. Thank You Mark and team!! read more

I'm thrilled to have finally found an HVAC service that I completely trust. Mark was fantastic and, in my 12+ years of home ownership, was the first technician to actually take the time to explain the mechanics of my particular equipment and the reasoning behind his diagnosis / recommendations. He provided me with several very cost-effective options to choose from for extending the life of my system. Awesome! For the past couple years, I had been using one of the big name HVAC companies here in Atlanta and it finally became clear to me that their top priority was to sell me a new system - including through very questionable scare tactics - rather than truly analyzing and servicing my existing system which was generally working just fine. Thankfully, that is when I decided to seek a second opinion, and one of my neighbors recommended GB Services. And now, as they say, the rest (including my old HVAC company) is history .... and, as I say, my financial future looks brighter! read more

I've had another popular AC company contracted for biannual cleanings and maintenance. The last 2 visits concerned me. Instead of regular maintenance, he brought brochures to sell me a new HVAC. He said according to the previous notes, it was time to replace my unit. NOT HAPPY, why was this a surprise to me, it's never been mentioned on previous services. My neighbor uses GB Services and after meeting with 3 other companies, GB Services offered to chemically clean my unit, check for leaks etc... about 2 hours later, my AC was pumping some seriously cold air. It was cooling better than the system should have been according to its standards. I appreciate that they actually troubleshooted the AC before telling me I needed a new $5,000 unit. It's been more than a month and I am still getting great service from my unit. Thanks GB Services for the troubleshooting, solving the issues and getting me cold air! BTW, I canceled my maintenance plan with the other company. read more

With the drastic temperature changes we've seen this year, I had a feeling our old furnace might give out and sure enough, last week I awoke to a bitter cold downstairs and a silent furnace. Immediately began looking online and found GB services and gave them a call. The receptionist was very kind and said someone would be over in the afternoon. Around 2 o'clock John arrived and I showed him to the furnace. He was very pleasant and chatty as he inspected the furnace. Other than being dusty and old he said nothing was wrong with it. Turns out it was simply our thermostat, which he replaced and took the time to explain to me how the new one functioned. The heat kicks on and has been running fine ever since and luckily my wallet didn't take a hit. John gave me his card with his cell phone number in case any problems occur in the future, and I will not hesitate to call. GB services went way beyond my expectations and I'd recommend them to anyone with heating/air issues. read more

Amazing service! I sent a message via yelp inquiring about an estimate on a dryer vent installation and general maintenance. As soon as they opened the next day, Mark called to set up an appointment. Very quick response time. Michael came out to perform the maintenance and provide the estimate and I am so glad I went with this company. Apparently the people who installed my unit (different company, NOT GB) switched the heating and cooling functions up! Talk about crazy. I have two units so it wasn't as obvious as you'd think, but Michael picked up that something seemed off and fixed it all up quickly. Things are SO MUCH better already. To sum it up- quick response time, appointment scheduled with quick turnaround time, excellent customer service, knows what they are doing. Very glad I changed companies and went with GB. read more

This is the first time I've ever written a company review before but after Mark and GB helped me with my AC issue I felt compelled to post something. Bottom line - they are awesome! I've been through the run around with several supposedly reputable HVAC companies in Atlanta but GB and Mark are hands down the best that I've dealt with. Their level of customer service is phenomenal and Mark really takes the time to explain the issue and what the cause might be. I didn't feel like just another customer. There is definitely a level of commitment and customer service at GB that is above and beyond anything else I've experienced with other companies. Mark even called me a few hours after he left to make sure everything was working properly. I'm definitely glad I found these guys and will be calling them for any future AC needs. read more

Very happy with GB services! I wasn't happy with my previous HVAC services provider who had come a month earlier and had not detected a low temperature split. I decided to give GB services a shot just based on the Yelp reviews. I asked for the rate of R22 freon over the phone and was given a reasonable rate (I called a few other companies). After booking an appointment I received an email to confirm it. I also got a call before the technician showed up. The technician was very professional and did exactly what I hired GB services for, adding freon without trying to upsell anything (and he weighed the freon which not all companies do). I received a very detailed digital receipt. I couldn't be happier with the entire process and strongly recommend every one to give them a try. I just wish I had found them earlier. read more

This is my first yelp review. I know, it's lame that I don't normally spread the good news of my favorite places--I'm just usually lazy about this sort of thing; however, GB Services was simply too good to go unrewarded. John and Freddy came out to tune up our furnace and clean our ducts (which I don't think had ever been cleaned, by the way--yikes!). Not only were these gentlemen professional and knowledgeable, but they were two of the most likable guys you'll ever meet. They came in, cleaned the ducts, tuned up the furnace, and even connected some ducts (free of charge!) that I didn't even know were disconnected. And they did this all while answering all of my questions in a friendly, understandable manner. I couldn't recommend a company any more highly than I recommend GB Services! read more

These guys are great! We needed AC for an office build, and I talked to a lot of HVAC companies. GB responded quickly through Yelp and got me on the schedule for a visit. They also confirmed we were in their service area. The guy that came out to help us look at our options was the same guy who did the install. And the owner came on the second day to help finish the job. We got a 4 unit ductless for a great price. The team was polite and professional. The install is tidy and clean, and they did a great job cleaning up their mess when they were done. The unit works great, and our power bill has dropped since we don't have to use the window unit we'd been limping along with. I would definitely recommend GB! I'm enjoying their handy work during this hot, humid weather! read more

I called up GB services maybe a month ago just to do general diagnostics on my system because I was concerned with excessively high gas bills. It was quick and easy to get the appointment; they showed up promptly, and Mark and his associate were professional and very communicative throughout the process. He described exactly what the problem was (as well as a couple other minor things that needed addressing) and helped explain next steps (which I still need to do--my bad) in an easily understandable way for someone completely unversed in heating/cooling systems. I will gladly have Mark's team back for an AC checkup when temps start rising (if they ever do). I heartily recommend them. read more

GB Services is the only heating and cooling company I rely on. Mark with GB Services is not only prompt, courteous, and efficient, his years of experience really show. I actually had used other companies previously, but they were unreliable and overly pricey. I even had to wait a long time before I'd get service. That is not the case with GB Services. They arrive quickly and fix only what needs to be fixed. I can trust them with all my HVAC needs. I don't take to writing reviews often, but this is one time where I felt compelled. When you get great customer service, how can you not be overjoyed. Keep up the great work Mark and GB Services and thank you for all you do! read more

Great service! I used someone previously & they came & fixed the issue temporarily but didn't find the major issue so the issue came back after not even a month after they left. My wife and I decided to go with someone else and we saw the great reviews for GB services and decided to try them out. Great decision! They were prompt, efficient, courteous, and surprisingly cheaper than who we'd used previously and they were supposedly giving us a discount! Also GB services is one of the few that work on residential rooftop units (CoolRay and Sears did not whom we considered previously). Any issues I have in the future with HVAC issues, I'll definitely be going to GB Services. read more

I'm a big fan of GB Services, and not simply b/c of the Great Britain reference. In looking for an HVAC server, fellow YELPers were super helpful in pointing me to GBS. Their immaculate ratings are for good reason. John came out at the end of a long day (6:45pm for a 3-4pm job), weather was bad and they kept me in the loop the whole time and were profusely apologetic. No worries. John was cheerful upon arrival and clearly loves what he does. He was a master diagnostician and talked me through everything he was doing. Turned out to be a simple fix and never pressured me into additional recommended services. He knows I'll call him again when that day comes. :) read more
