George and Adrian were awesome. They did a through review of our AC concerns, provided several options, explained everything in detail and Brad was willing to work with our financial concerns. New AC unit will be installed tomorrow morning!
Thanks for your patience with us!

Juan was very knowledgeable and his attention to detail was able to save me money and extend the life of my unit. He did an excellent job and was kind throughout the entire process. I will be calling for Juan for future repairs or replacement work.

Fantastic service. Dominic came out to clean the coil, replace a capacitor and got me on a membership plan. All prices are way less than competitors!

Outstanding Service from The On Time Expert Air Conditioning Technician and His Team.

I recently had the pleasure of working with an AC technician/Manager George and his group of trainees-Logan and Koby, and I couldnt be more impressed. From the moment they arrived, it was clear they were knowledgeable, professional, and committed to getting the job done right.

The lead technician/manager George, was not only highly skilled but also incredibly patient and thorough in explaining what needed to be done and why. He took the time to educate both me and his trainees, ensuring they understood each step of the process while maintaining excellent service and efficiency.

The trainees were attentive, respectful, and eager to learn. Under the guidance of their mentor/manager, they worked together seamlessly and handled everything with care.

Its rare to see such a strong mix of experience, professionalism, and mentorship in one visit. I highly recommend this team George, Koby and Logan for anyone needing AC services. Youll not only get quality work but also support the development of the next generation of top-tier technicians.

Weve used On Time Experts for many years and have always been happy with their work and customer service. Marco did a great job with our spring service check yesterday. He was thorough, respectful and did a nice job cleaning up our unit. He even vacuumed the floor under the ceiling access before he left!

Had a great experience with On Time Experts. Dom was professional, knowledgeable, and took the time to explain what was going on with my system. He recommended a start kit after replacing my compressor, and it made total sense once he walked me through the numbers. I appreciated the honesty and the quick turnaround. Would definitely recommend!

The two guys that showed up today were amazing! They walked me through everything they were doing, and it was so much more than I expected. My system was crazy dirty, and they cleaned everything! They even went above and beyond with a few questions I had that were out of scope. Totally the best these guys are my go-to forever!!!

Joey serviced my air conditioner today and conducted a thorough inspection of both the inner and outer units. He meticulously checked every detail of the system and quickly identified several faulty parts that required replacement. I was particularly impressed with the fair pricing he provided through the company, and his suggestions were both honest and insightful. I strongly recommend working with him; you wont be disappointed!

On time Experts showed on a Saturday to check my current system. Dominic did a good job identifying the problem. Turned out I needed a new system and he helped get it set up for installation the very next dayon a Sunday. Great job across the board by all involved.

The On Time Experts AC repair is a great company. We called this morning and had technicians at our door within a few hours. George and Evan did an amazing job. They are friendly, professional, knowledgeable, and efficient. They diagnosed and resolved the issue in a timely manner. We will use this company again in the future.

Bernie was extremely professional and very knowledgeable. He showed me step-by-step the work he was doing and allowed me to see his level of detail and excellence in taking care of my units. He also explained the maintenance plan to me without being pushy. I ended up purchasing it because I think its a great deal and he did a nice job explaining it.

This was my first experience with On Time Experts. I had seen multiple commercials on a local DFW station about an AC check up special. When my AC went out, I decided to give them a call. I was told that the diagnostic charge was $95. A bit later in the conversation the woman asked if I was interested in learning about the membership. No pressure - just the information. It turns out that the membership is a really good deal (more than pays for itself!!) The technicians, Joey and Chase, arrived on time, were very courteous and answered all my questions. This was a great experience. I am having to wait on a part - I might update this as the process continues. So far - so good. I'm posting a pic of all that is included in the membership.
