Trusted HVAC Services in Windsor Mill, MD

Ryan went over and above setting up the temporary portable units for me and assisting with my technical problem

D’Sean was so professional and presented information clearly and was a pleasure to interact with

Very easy to work with on our AC unit breaking down. Thorough and thoughtful care and recommendations throughout the entire process. Could not have been any better.

We can’t recommend Complete Climate Services enough. Corey was great to work with, he was friendly and efficient, respected our preferences, and didn’t try to upsell us on anything. Prices were really reasonable too. We would definitely use them again! Update, 9/4/26: We definitely used them again, and we still received top-tier service! De’Shaun was lovely to work with, he was efficient, honest, and kind. If you have an issue and you don’t want to be upsold, call them, they won’t let you down!

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.

Responsive, professional service, highly recommend

He was pleasant and efficient. He explained his review of my system. I would highly recommend him.

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.

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.

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.
