I've used Great Works Heating & Air Conditioning twice over the past year and have had excellent…read moreexperiences both times. The first visit, he diagnosed the issue within minutes, explained exactly what part I needed, and even pointed me in the right direction to get it so I could install it myself the next day--saving me time and money. This most recent visit was just as impressive. He came out first thing Monday morning and helped trace down a strange voltage issue that kept our heat from coming on. Instead of pushing unnecessary replacements like I'm sure some companies would have, he carefully isolated the problem to a loose plug on the furnace control board. He reseated it, and within minutes our heat was back up and running. Honest, knowledgeable, efficient, and clearly focused on fixing the real problem--not upselling. I highly recommend Great Works to anyone needing reliable HVAC service.

Absolutely AMAZING experience!!!! I was left with few options when my a/c decided to stop working…read morein the middle of the night in August, in Atlanta, and my previous a/c vendor was unavailable due to the COVID-19 pandemic. Being a pet mom I always worry about my little fur babies, and seeing them panting and looking for relief from the heat only added to my stress! I was first pleasantly surprised to see that this company opened as early as 7 AM! I then read the reviews, as most of us that use this site do! I said a prayer and went ahead and gave Porter HVAC a call, and boy was it a blessing that I did! Mr. Porter answered the early 7AM call and was extremely professional and polite. He told me that because of my location which is in metro Atlanta, he could stop by my house within a couple of hours. That immediately brought a smile to my face! Then something happened that I didn't think was possible anymore........he did exactly what he said that he would do, he was in my driveway within 2 hours! Not only did he show up like he said that he would, he was wearing a face mask for safety during this pandemic. Within less than two minutes of me showing him my set up, he was able to diagnose the issue. He was very courteous and even broke the news to me slowly that my unit would need to be replaced sooner than later..... *inserts crying face.* To be fair, the unit was almost 30 years old! I was really put at ease when I saw that Mr. Porter wasn't pushy about trying to make me buy an a/c unit and in fact, he gave me an option that would cool me down for the time being. My pups and I were once again in the a/c and there was no question in my mind as to whether or not I would let Mr. Porter come back out to replace the unit. When Mr. Porter came back out to replace the unit, he once again showed up when he said that he would. Mr. Porter also provided updates during the repair, he stayed within the timeframe that he gave me when we scheduled the repair, the removal and installation of the inside and outside units was great, and he cleaned up after the work was completed. A+ all around! I highly recommend!

This is an update to my previous glowing review singing their praises. Unfortunately, they did not…read morestand the test of time and I definitely would not recommend Maintenance Unlimited to anyone. The good news is that I suffered the headache others can avoid :) First, the prior work done was not completed and I was hoping they would come back to finish the project properly so that all the systems installed or modified can function correctly. They didn't show up after 2 months of scheduling and constant rescheduling of appointments. All the folks (Darrell & Pam) I mentioned in the previous review turned out to be unreliable - excuse upon excuse. I eventually gave up and found another provider to fix up all their mess and wrap up the project correctly. Second, there were several competency issues with the duct work done. A few examples are: 1) should the supply from an ERV that outputs 200 CFM be connected to the plenum of an HVAV that outputs 2000 CFM? A pro should know that the HVAC will win and blow air back into the ERV. 2) Similarly, should the supply from a Dehumidifier that blows ~100 CFM be connected to the same HVAC plenum? These are seemingly basic air flow considerations any HVAC pro should know. 3) They put only 2 returns (14in and 10in flex ducts) on a 2000 CFM HVAC. I'm not an HVAC pro but even I knew this was not enough return. I had to point out to Darrell to use a duct sizing calculator to figure out how much return was still missing. 4) They couldn't wire my thermostat (Nest - latest gen) to the dehumidifier (Aprilaire E080) correctly too. So many red flags... Third, as a last resort, I called the office to ask to speak to a manager/supervisor. It seems that office rep is pre-programmed to state someone will call back "at their earliest convenience" with an unpleasant attitude to boot. After more than 3 weeks, no call back. Overall, my experience started well but crashed badly. Life is about lessons and even better when you can learn from others' failures. This was a nightmare over a 5 month period and I hope nobody experiences this with them again.
