September 2,2026 My AC units went out, and after receiving three different diagnostic opinions, I finally decided to go with Complete Climate Services, and I’m so glad I did! They had serviced my AC units several times before, so I already knew they were professional and reliable. What stood out to me the most was how they made my family and me feel comfortable while we waited for the new system to be installed. They even provided and installed window units to help keep us comfortable until the job was completed. From start to finish, the entire team was professional, courteous, knowledgeable, and respectful. They did an excellent job with the installation, and I truly appreciate the care they showed my family throughout the entire process. I would like to personally thank the entire team, Michael, Ryan, Tristan, Zachary, Ibn, De’Sean, and the two other gentlemen who assisted with the installation. I truly appreciate each of you for your hard work, professionalism, and for making this experience as smooth as possible. Lastly, De’Sean came back to remove the window units, the ones we had grown to love so much! 😂 They did a great job keeping us comfortable while we waited, but there’s nothing like having a brand-new HVAC system! 🙌🏽🏠 We are extremely happy and satisfied with the service Complete Climate Services provided. They truly went above and beyond, and I would definitely recommend them to anyone looking for quality HVAC service. Great job and THANK YOU for taking such good care of us! ⭐⭐⭐⭐⭐ August 1, 2026, my AC system stopped working. I contacted Climate Control, and they came out to assess the situation. After a thorough evaluation, they recommended replacing my system with a new, energy-efficient unit. In the meantime, they installed temporary window units throughout my home so I can stay comfortable while I wait for the new system to be installed. The technician was professional, knowledgeable, and a pleasure to work with. The next step is installation of the new HVAC system. Stay tuned! I had an excellent experience with De’Sean from Complete Climate Services LLC. He was extremely professional, knowledgeable, and took the time to thoroughly explain everything he was doing throughout the service visit. His attention to detail and willingness to answer my questions left a very positive impression. I recently saw De’Sean featured on Channel 11 News in Baltimore, where he shared his journey through the NCIA Vocational Training Center. It’s inspiring to see how programs like this provide free HVAC training, help individuals earn certifications, secure employment, and overcome barriers to success. I have been a customer of Complete Climate Services for four years, and I have consistently been pleased with the quality of service and professionalism their team provides. De’Sean is a great example of the outstanding employees they have. I highly recommend Complete Climate Services to anyone looking for reliable and trustworthy HVAC service. ⭐⭐⭐⭐⭐ First review - 4 years ago After scheduling an appointment for Monday July 3rd, I received a call back that they had a cancellation and could come the same day. Mike was great, very professional and showed me the problem. In less than an hour my AC was up and running. I will definitely use them again.
Response from the owner:Julia, thank you for the kind review. We’re glad we could fit you in sooner due to the cancellation, and that Mike was able to clearly explain the issue and get your AC running again so quickly. We appreciate your trust and look forward to helping you again when you need us.

I had a new Trane air conditioner unit installed on my third-floor rooftop (by crane), and the old unit removed. Big projects like this always make me a bit nervous, but everything was in good hands and went like clockwork. I highly recommend Complete Climate Services.
Response from the owner:Steve, thanks for taking the time to share this. We’re glad the rooftop Trane installation and removal went smoothly and that our team helped ease the nerves that come with a big crane job. We appreciate the recommendation and the opportunity to help with your home’s comfort.

De'Sean was extremely nice and helpful. I was working in the yard so my wife met him at the door. She came and got me and said "The AC guy De'Sean is here and he is VERY nice" - a direct quote.
Response from the owner:Thanks, Dan, for the 5-star review. We’re glad De’Sean was so friendly and helpful, and that your wife felt comfortable when he arrived while you were outside. We appreciate you choosing Complete Climate Services LLC.

Customer service is outstanding. I just had a technical problem where my recently installed HVAC system's air-conditioner was cooling but the humidity was high, like 75%. Zachary came out a couple of times and scoped out everything; did some tech stuff; (resetting functions, magic, etc.) and right now, maybe an hour later, humidity is down to 60%. And it was all without charge. Additionally, since I got the system, my gas and electric bill has been half of what it was before. Hence, I love these guys.
Response from the owner:Thank you, Mary, for your kind words. It's wonderful to hear that our team, especially Zach, provided efficient and thorough service for your new system estimate. We aim to make the process as smooth as possible, even when a full HVAC replacement is necessary.

De’Sean was exceptional, explained and showed me all the work done, and made the process very clear and easy!

Called Complete Climate Services after our AC stopped cooling (system was blowing air but not cold). Turned out to be a mix of a dirty air filter and a clogged condensate drain line, which I’d already started addressing myself. John came out, was friendly and thorough, walked me through what he was checking, and confirmed my fixes had solved it — no charge for the visit. Really appreciated the honesty and clear explanation instead of trying to sell me something I didn’t need. We liked the experience enough that we’re signing up for their maintenance plan. Would highly recommend
Response from the owner:Hi Dan, thanks for taking the time to share this. We’re glad John could confirm the filter and drain line issue was resolved, explain everything clearly, and keep the visit focused on what you actually needed. We truly appreciate your trust and look forward to taking great care of your system with the maintenance plan.
