GB Services

I have been way overdue in writing this review… But that doesn’t mean we were not thrilled with Mark and his team. I am so glad I found GB Services! We recently purchased a «renovated» home that was a mess, especially the HVAC. We had just moved back to the area so didn’t have a team of trusted ppl to help with the repairs, advice, etc. We were overwhelmed and getting tons of crazy quotes and conflicting info. Mark stepped in and was able to troubleshoot things not only wrong with our HVAC system but also our non-​functioning brand new hot water heater, insulation, etc. These were repairs he was not going to perform but helped me understand what we needed to do or not do. We would trust Mark with any repair and consider him our expert. Also, Joey and John put in our new system and did a great job, such a pleasure to work with these guys. And can’t forget Judy that runs the office/​scheduling, always friendly and helpful. Seriously, if you are trying to find solid HVAC experts/​team that care and treat you like close friends look no further! We love these guys!!!

I can only say positive things about GB Services and I highly recommend to everyone need of HVAC Service. They are very responsive, timely, very friendly and they have great service. Thanks to Judi and Joey, my A/​C is fixed very quickly in these cold weathers of Atlanta.
Thumbs up to GB Services.

It was cold outside and in the house today, furnace stopped working. Thermostat set for 70 degrees, actual temperature was 63 degrees.
I have been on the GB Services maintenance plan for the previous year, which includes service discounts and priority treatment. I got to put this to the test today because I called them at 4pm when I discovered my furnace wasn’t working. The forecast is for close to freezing temperatures tonight, so I was already planning on getting out the space heaters for the night, anticipating that I would get an appointment for sometime tomorrow.
As it turned out, they had a couple of service techs in the area and stopped by after their last service call of the day. By 6pm, they had my furnace running again. Fortunately the problem was only a loose fuse inside the heating unit, but had they not showed up, it would have been a cold night in the house before it was tightened.
Very happy with the service I received.

GB Services went above and beyond!!!
We just moved into our new house in the city. Of course we excited but some thieves quickly took that excitement away from us. Not a week after closing, both AC units were stolen. Thinking one of the units were for heat, I freaked out. I called around trying to get quotes for new units and installation. I called a place that I used in the past and they said it would be at least a week for them to get out to even look at it. I told them I had pictures and serial #‘s etc, but they were still like no.
I called GB services, Judi was amazing. After I told her my story, she said I’m not sure if we could come out that soon but said wait a second and put me on hold. She came back and asked that I send her pictures of the damage and serial numbers, By the days end I had a quote and a time for them to come and install the new systems. She also informed me that neither of the units pertained to heat to so we were ok there. She followed up with me and Mark recommended a guy that does cages and he was awesome as well. The installation went smoothly and we had paperwork for our insurance company very quick.
All in all, I would use them again. I do hate how the story started but I am glad that we have a company we can trust for our HVAC needs in the future. Thank you GB!
Hope B.

Had an incredible positive experience. Mark, the owner of the business, came personally to check my furnace problem, explored all the options with maximum benefits to me and probably even less advantageous for him. In the end when i asked him about a proposal for a new furnace gave a prompt and very honest bid. Moreover, gave a fair comparison with other furnaces and conceded that the price range i was looking for would be better accommodated by a competitive brand. Charged me nothing for the visit, though other companies asked for a service call fee. He finally did not get the order, but found a loyal potential customer for future.
Thank you, Mark

I’ll just echo what other folks have said: G.B. Services is great. They came out the same day I called, gave me a great deal, and got the part I needed there quickly.
They also took the time to talk me through the problems, and gave me several additional suggests to help address related issues. I can’t recommend them highly enough.

I agree with the other reviews on here. Mark and his crew are top notch. He is honest and straightforward plus they did a great job with installing a new A/​C unit for my condo. He provided me with 4 pricing options and was able to answer any questions I had.
He also visiting another property I own and inspected a furnace that another company (with lots of TV ads which don’t live up to the company’s name) told me needed to be replaced. There was nothing wrong with the unit! Thanks Mark for your honest and thorough evaluation. I’ll be sure to call you in the future if I ever need anything.

Thorough courteous and consistent service. Wierd, but with my service contract, I still have to provide my own filters. My previous HVAC contract included filters, but they were JUST changing filters, not doing all the other techie stuff that GB does.

after being on the phone a while to schedule a service they finally inform me they do not service my area in Atlanta 30 310. But they service the surrounding. I asked if they service SW AT and they said yes until I gave them the zip.

I can’t recommend GB Services enough. They’re the first people I call for all things HVAC because of the quality of their work and the time they take to educate you on the issue at hand and your options to resolve it. Mark and the team clearly take pride in their work and hold themselves to a very high standard. I’m happy to see their good reputation and business have grown over the years — deservedly so.
I found them on Unilocal after I’d just moved to the area. I had a house with three HVAC systems (electric cooling and gas heating). It had a lot of issues (mainly very poor temp and humidity control due to what I suspected to be overcapacity when they added new square footage to the house and didn’t size the systems appropriately). I was new to the area and selected GB Services based on their Unilocal rating. I had tried a couple other competitors for the same upstairs unit that kept failing, but wasn’t satisfied enough to try them again.
I’ve since moved to a condo with an electric heat pump, and recently my compressor shorted. My best choice was to replace the system due to age and a few other factors as replacing the compressor would’ve been costly and only given me a one-​year warranty (compared to a 10-​yr warranty on a new system). I explored other service providers to get additional quotes as it was an expensive job, but ended up going with GB Services as they continue to stand out among their peers. The whole team — from the dispatcher to the technicians — works very hard to ensure you are treated well and understand the process every step of the way. That is saying a lot in a crowded market where it can be tough to find a reputable provider.
Thank you Mark and team!

Integrity, honesty, and trustworthy. These are words I use to describe John Molina and Mark Moore. We had a 23 year old furnace/​AC coil that was giving us fits, and they were out to look at our situation. Mark came out first and assessed the existing setup. He then sat with me in the drive for almost an hour (after hours) explaining our options, and asked us to call back with our thoughts. He even called us in Saturday to follow up. To make a long story short, we opted for a new unit in the attic. John then came out, measured the unit and the airflow and advised us of the proper solution.
What neither of them know is that I am well experienced in heating and cooling on an industrial level. I can tell you that their calculations, estimations, and recommendations were spot on. There was no BS in their work.
I highly recommend GB Services. In fact, go to the other competitors and talk to them. Then call GB Services. You’ll see the difference right away. No fancy talk, no making up «facts» on the spot, no up selling. Just honesty and hard work.
Well done, gentlemen!

There is a good reason GB has over 75 reviews and a 5 star rating. No other provider in Atlanta can stand up to the knowledge, integrity, and service that Mark and his team provide. I came to GB Services because my home warranty company had sent 3 companies out and could not tell me what the issue with my a/​c was. After 9 visits and 2 months of intermittent a/​c in the heat of summer (stay away from 2 – 10 Home Warranties!) I was told that the issue was a part that was not covered that would have to be fixed before they would even talk to me anymore. I also had to pay another deductible. At that point I decided I needed to hire someone who actually knew hvac systems and with 5 stars it was a no brainer who I was choosing. Mark came out the first time and was not able to determine the cause. That’s OK… he did not BS me and he was adamant about not just replacing parts as a process of elimination. Since he could not replicate the issue he gave me a checklist of things that I could do to narrow what might be wrong and gave me his phone number. When we thought we had it narrowed to the part (the zone control board) I decided to replace it on my own. I am a computer guy and know enough about electronics to get myself into trouble. After installing the board it didn’t work (crazy, I know), but mainly because I didn’t know enough about the hvac system to program the zone control board settings for my unit. I called Mark and he graciously let me ask him a series of questions about the setup knowing that I had done it myself. When it still did not work he told me instead of paying him to come out to call the boards manufacture because they could help me for free. Who does that? After making sure everything was setup correctly and realizing the board was not the culprit I called Mark back and he was at my house within an hour. Now that he was able to see the unit acting up, he diagnosed the problem in 20 minutes and had it fixed shortly after. I saved a ton by shipping the board back and he didn’t charge me for a second visit, only the fan relay that was the issue all along. Thank you Mark and Judy, you will be my go to a/​c people from here on out, and as long as you keep providing top tier service I will recommend you to everyone I know who needs a/​c work.

Had Mark come out initially for a 75 year old home that we just bought and are prepping to rent out. The home has very old asbestos ridden ductwork etc. but unlike the other two companies we had come out, GB services only recommended we do the bare minimum and saved us a ton of money for now (which was necessary since everything else needs fixing in this house too) by suggesting we just repair the current ductwork and service the furnace. He let us know that we can wait a few years before getting an entire new system (which is smart on their end since in the long run we will be spending more money with them… if you consider that we will trust them with the repairs and maintenance on this old system for the next few years and then have them put in the new one).
Mark was very honest, kind, and prompt for the initial consult. They sent a guy named John out this morning who arrived 5 minutes early (a rarity if you ever have to deal with contractors all the time) to repair the ductwork and service the furnace and he recommended that we move the thermostat to a new location and mentioned that we need a new capacitor. At first, I figured that he’s pulling the classic last minute up-​sell on additional crap we don’t really need but then when I saw the final cost of everything I understood that he was doing us a favor and even replaced our air filter for free. He also gave us a very fair price on everything (thanks Google!).
My only business recommendation to GB would be that the phone call handling go more smoothly. Judi handled all of our calls and she is super sweet and lovely but we had a few weeks of delay just trying to get a call back and had last minute appt changes on their end twice and another time she left a voicemail saying that our appt was changed but forgot to say to when and then when I called to clarify she said that she mentioned it in the voicemail (double-​checked again after and nope).
Overall though, I trust them and will be calling GB for any future needs.

I had another popular AC company contracted for biannual cleanings. The last 2 visits concerned me. Recently, rather than a visit, he brought stuff in to sell me a new HVAC. He said according to the previous notes, it was time to replace my unit. NOT HAPPY with this surprise.
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 at the unit by the time it was in my vents and home, 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.

So my A/​C went out and I did not hesitate to call on GB Services again. They told me last time «change your filters once a month!» I didn’t. My system clogged and coils froze. Oops. Lesson learned.
So John, the wonderful technician, needed a water source and asked if the spigot in the front worked. I said no, it’s been broken since I moved in. He said really? Let me look at something …2 secs later. Ok it’s fixed. Really?! I was going to call a plumber. The valve had never been turned on. I ASSumed if the indoor water was working, the outdoor water should work. Sigh… #imjustagirl. GB Services, and John, are SO great, so responsive, and have such integrity I highly, highly recommend them. Also, they have a British red phone booth in front of their business and the Union Jack as part of their logo, and their street is Trafalgar way. All images of the England my favourite country in the world. Keep Calm… and Change your Filters!

I’ve had GB services come out a few times and would highly recommend them. They are courteous (e.g., putting booties on their shoes before entering the house), honest and transparent, quick and knowledgeable, and always take the time to educate me on what’s going on. They give recommendations for service without pushing it.

Mark was extremely personable and throughly explained everything to me! This is a company you can trust in your home that will give you an excellent customer experience!

Great service!
I am selling my house, and wanted to be sure that the HVAC and water heater were in good running order before the house goes on the market.
GB Services came when scheduled, did a very thorough check of both systems, fixed several minor issues at no additional cost, and gave me a list of things to consider, along with the costs for each.
They were thorough, communicated well, and gave me the information I needed. No extras on the cost, and they were on time.
I couldn’t ask for more.

I found GB Services on here after having a bad experience with another company. I could not be happier with the services they provided. I live on the third/​fourth floor of a walk up loft building in downtown (probably one of the most difficult situations when having to replace a HVAC unit and water heater due to the steps and no elevator); however, they were very professional and did the job without any problems! They also were very quick and had the whole job completed (and took away the old unites) by the end of the day. When asking for a quote on the cost of replacement, they broke it down easily into three different budget ranges with all the pros and cons of each. No pressure! Finally, they were very quick and response when I needed to have them come out.
Highly Recommend!

John and Mark did a top notch job! No corners were cut! They used actual calculators to determine my system needs versus the competitors sucking an idea out of the air!
They did great work. Very well priced and over delivered in every aspect! I wouldn’t hesitate to use them again!
If I had picked a competitor I’m fairly sure I would have been concerned about maintaining an expensive system but not with these guys!
