  • How to Find the Best HVAC Contractor in Atlanta

    How to Find the Best HVAC Contractor in Atlanta

  • Excellent Experience
    I have just recently parted ways with my home warranty company because of repeated repairs to my A/C unit and their unwillingness to replace it.  

    However, Saun came out within 24 hours of my call because my unit was totally out.  He diagnosed the problem, which turned out to be a mere maintenance issue where my unit coils needed to be cleaned, changed my filters, cleaned up the drainage, and advised of how to maintain our unit going forward.  My A/C was back up and running immediately!

    I am so grateful for the prompt, diligent, and careful service I was provided.  Additionally, the technician wore a mask, respected social distancing guidelines, but gave us excellent service.  I am sticking with this company for my future a/c needs.

  • Pleased With the Fantastic Job
    I requested service from Maintenance Unlimited a few months ago. It was easy to schedule an appointment and everyone I interacted with was very professional. Darrell assisted me and was able to determine the problem with my AC very quickly as well as explain how the system was supposed to work. I liked that the company was communicative of what time the tech(s) would arrive and showed up as expected as well as keeping me informed on what was needed to fix the problem. I was pleased with their service.

  • Very Pleased with the Service!
    The serviceman who came was professional and gave me options in various price ranges. I was able to select an option that worked for my budget and gave me the repairs I needed. I really liked that the money I spent can be applied to a new unit. I was very pleased, would use this company again, and would recommend them.

  • Prices are Fair
    I started using Maintenance Unlimited about six years ago when I bought a very old house and they have done work here a number of times. Sean was awesome. They show up on time, usually with very short notice. Their prices are fair. They back up their work. I highly recommend them to anyone needing good service.

  • Great Work
    Sean and his team have taken care of our HVAC needs for years. They installed a new system three years ago with Nest thermostats. He came out for servicing last week. Great job

  • Prompt and Efficient Service
    The two A/C units in my house had decided to stop working within the last 3 years during summer.  We shopped around big time and found Maintenance Unlimited offer the best price on the total of equipment and labor. We ordered the new A/C units from Maintenance Unlimited both times. The technician teams from Maintenance Unlimited had installed both units with our 100% satisfaction and expectation. Also, I think their technicians were dispatched to come to our house for at least 3 or 4 times upon our requests to check on some minor concerns and adjustments during the warranty period. Each service call was free of charge and prompt. I definitely recommend this company and their services.

  • I only make one call for all things hearing and air.

    Reliable. Reasonable pricing. Responsible follow up. Can't complain. After 10 years of service and solid work, I only make one call for all things hearing and air. I even call for major plumbing issues now.

    - Mark L.

  • Very Knowledgeable
    The tech who came to my house was very knowledgeable, provided me with good options on how to save money long term on my maintenance, and fixed the problem that I had in short order. I’d recommend them to anyone.

  • Couldn't Be Happier With Their Service!
    We have relied on Maintenance Unlimited for all of our HVAC needs. Whether installing a new system or repairing issues with an existing one, they are professional, responsive, and highly capable. Couldn’t be happier with their service.

  • Incredibly Happy and Satisfied
    Incredibly happy and satisfied with this company. I spent four days trying to get someone to come out and fix my HVAC, talked to 7 other companies and they either couldn’t schedule me this week or just wanted to sell me a new HVAC right away without fixing the old one. I called Sean this morning at 7:30 am and he was at my home within 45 minutes, carefully examined the unit, and had it up and running within an hour! He also quoted us for a new unit at a great price. Will definitely have my business going forward!

  • Great Service
    Sean has services in my business and home for over 12 years. I highly recommend this company. I have had great service including after hours.

  • Highly Recommended
    Sean and his team are awesome to work with! He was on time for the appointment and very professional too! You will not find a better Heating and A/C repair and maintenance company in Atlanta! I highly recommend his company for all your A/C needs.

  • Sean Really Knows His Stuff
    Someone came out the day I called...none of this "diagnostic fee" business, just good old-fashioned customer service. Sean could tell right away that the issue was Freon (I had no clue)--and got someone out the next morning (the system had to defrost overnight). I totally freaked out when I got home from work the next day and the system was out again!--once again, someone came out quickly...turns out it was just a circuit breaker; Sean really knows his stuff!!!

  • Great Experience!
    We recently found ourselves without hot water or heat due to issues with our venting and water heater. I called multiple companies who couldn't fit us in on the same day. Maintenance unlimited came out the same day, scheduled the work to be fixed the next day. Their associate, Darrell, was so knowledgeable and professional. The guys came out the next day, worked tirelessly through the rain (all day), and had us back up and running by that evening. I would definitely recommend it! Great experience!

  • Total Lifesaver
    Total Lifesaver! Our AC stopped working on a Friday night---just hours before our flight for a long vacation. Not only did Maintenance Unlimited answer the phone before 9 am on a Saturday, but they also expedited service and sent a technician before noon. Sean arrived on time...and with good news: within five minutes he'd diagnosed the problem, replaced a faulty capacitor, and had our 18-year-old AC unit back up and running. I could not imagine a better outcome.

  • Great Experience
    Great Experience.  Marvelous was here within 45 minutes of my initial call.  He diagnosed the problem in minutes, changed the part.  His expertise in his field and great customer service made the difference in this customer's mind.  I would highly recommend these folks.  Their pricing for the call and parts was VERY reasonable compared to some other quotes.  Great Job!

  • Very Professional and Great Price
    Very professional and great price. I had both my air conditioner and Furnace replaced with Maintenance Unlimited. The issue with air conditioning or furnace repair or replacement is that few people have a good understanding of what really is important and what to look out for. I have extensive knowledge in this field. Mr. McKinney the owner of Maintenance Unlimited answered all my questions and concerns. The work was professional and very thorough. They never cut corners and they took their time to make sure everything was done right. Before I contacted Maintenance unlimited I got a few quotes from other companies. I quickly realized there are a lot of salesmen that will be quick to take your money. But when I asked some basics in how the installation was going to be performed the could not answer the most fundamental questions. You cannot go wrong with Maintenance Unlimited.

  • Same-Day Appointments
    Called Sunday morning and received a call back with a same-day appointment. I was surprised they were able to get out and get the job done especially on a Sunday. I highly recommend this business and feel good about supporting a local business. You won't be disappointed. Reasonable pricing, prompt, and great customer service.

    - Kylie G.

  • Amazing Company
    I'm a local guy who likes supporting local businesses. Sean was the epitome of professionalism when I called in about my HVAC at my new place not working. He came out for the diagnostic check and let me know the thermostat I should buy. He was amazing and even offered to come back out free of charge to install it himself so I would know it was done right. He followed through and I will be calling and referring him for all air needs.
    He also has a ridiculously soulful voice lol
