What Customers Say

“I had an excellent experience with On Time Experts for my air conditioning and heating maintenance. The service was professional, prompt, and thorough from start to finish. A special thank you to Christian M. for providing outstanding customer service. He was knowledgeable, courteous, and took the time to explain everything clearly. He performed the maintenance with great attention to detail and made sure all my questions were answered. I truly appreciate his professionalism and dedication to quality service. I highly recommend On Time Experts, and if you have the opportunity, ask for Christian M.—you'll be in great hands!”

“Marlin did an excellent job with our HVAC maintenance. He was thorough, professional, and took the time to check everything carefully rather than rushing through it. He explained what he was doing, answered my questions clearly, and made sure the system was running properly before he left. On top of that, he was very friendly and respectful throughout the visit. It’s always reassuring to have someone who is both competent and easy to work with. I really appreciate the quality of his service and would definitely recommend him.”

Vaibhav Kumar

“I’ve come to rely on Otto and the team at On Time. He arrived early as requested, worked efficiently and cleanly, and was friendly throughout the visit. During my maintenance service, he not only handled himself professionally but also identified a potential issue before it became a bigger problem. He recommended installing a UV light in the plenum to help eliminate moisture, spores, and bacteria after spotting a small area of organic growth beginning to form. It wasn’t inexpensive, but the member discount made a noticeable difference. After two years as a customer, I continue to be impressed by the standard Otto and the company maintain. As an aside, he helped me wrangle 2 black birds which had somehow gotten inside the house and were creating chaos. 🐦‍⬛ Extra credit.”

“I highly recommend On Time Experts to anyone in need of professional HVAC services. My experience began on a sweltering summer night when my air conditioning unit finally gave out. It had been struggling for a while, leading to a steady climb in my monthly electric bills, and I knew it was time to take action. What first impressed me was their accessibility; I was able to jump online and schedule an appointment at 4:30 AM. By the next morning, the office followed up promptly to confirm the details and my appointment time. Beyond the convenience, I chose On Time Experts because of their impressive 60+ years of experience and the fact that they are a family-owned business. When you are investing in a system that needs to last for years, that kind of longevity and personal commitment matters. Our service technician, Muhammad, arrived exactly on schedule and got straight to work. After a thorough diagnostic, he provided a clear breakdown of my options. While a temporary repair was possible, Muhammad honestly explained that it wouldn't be a sustainable long-term solution and suggested considering a full replacement. After insightful discussions with both Muhammad and his supervisor, Jef”

“Great Company! Collin the tech came out late on a Friday night and worked with us on a Saturday morning to discuss options for a new unit and installed same day. Installation technicians were professional so so kind and helpful. highly recommend”

Leah Maacaulay

“I really appreciate Chris for coming back a second time when we experienced an issue with no water in our irrigation system. He was professional, helpful, and took the time to assess the situation and provide valuable advice. It was a thoughtful gesture and showed great customer service.”

“If I could give OnTime Experts Plumbing Division more than 5 stars, I would. I'll admit it—we initially thought their pricing was a little higher than other companies and even questioned whether some of the work they recommended was truly necessary. Because of that, we hired another plumbing company to perform a repair. That turned out to be a costly lesson. The other company completed the work, but none of it was installed up to code. The scary part is that we never would have known if OnTime hadn't been willing to inspect the work afterward. Not only did they identify the issues, but they took the time to explain everything clearly and helped ensure everything was brought up to code correctly. Jacob, CJ, and Bobby were absolutely outstanding throughout the entire process. They were professional, knowledgeable, patient, and genuinely cared about doing the job right. When we hit a snag, they didn't just send an email or make a phone call—they came to our home personally to discuss the situation and help us understand our options. That level of customer service is rare these days. Yes, OnTime may charge a little more than some competitors, but now I understand why. You're payi”

“We had a few issues with scheduling between our schedule and the high demand A/C people are in right now, but the actual service was top notch! Keith did a wonderful job cleaning and inspecting our system. He communicated very well about what was being done, even while I was at work, and offered helpful suggestions so that we could keep our unit in top shape. We appreciate his hard work and expertise and will be calling to have him back again for maintenance in the fall.”

Helen S

“We had a wonderful experience with On Time Experts when we needed help with our AC. From the beginning, they were professional, patient, and truly understanding of our family’s situation. As a military and first-responder family, we appreciate businesses that understand the importance of taking care of families who give so much to serve others. The team took the time to explain everything, answer our questions, and make sure we felt comfortable with the repair. Their patience, kindness, and willingness to help really stood out to us. It’s not just about fixing an AC—it’s about how you treat people, and On Time Experts treated our family with respect and genuine care. We are very thankful for their service and would definitely recommend On Time Experts to other military, first-responder, and local families! 🇺🇸”

Leisa Lane

“I recently had an HVAC technician by the name of Co come out to service my system, and I must say I was very impressed with the experience. Co arrived on time, was professional and courteous, and took the time to explain the issue clearly before starting any work. He worked efficiently, made sure everything was running properly, and answered all of my questions patiently. What stood out most was Co's honesty and attention to detail. My system is working much better now, and I appreciate the quality service provided. I would definitely recommend Co to anyone needing HVAC work done.”

Erika Walker

“Barry was absolutely fantastic! He was extremely knowledgeable, professional, and took the time to explain everything to us in a way that was easy to understand. He was very thorough, answered all of our questions patiently, and never made us feel rushed. We highly recommend Barry and On Time Experts for any HVAC needs. Thank you for the outstanding service!”

Aixa Galarza

“Arrived same day, excellent customer service explained in detail the issue with the plumbing every step of the way. Major job-mainline was tunneled 110 feet under slab, he and helper replaced all 4 inch mailine and 2 bathroom drainlines. Was caring enough to take photos and explain, and to document his findings. He was tidy as they were sure to cleanup jobsite daily. I would highly recommend Luis and his apprentice. He communicated well on text as well. He was helpful explaining through this 5 week long process. He took care to keep the mud out of the house.”

Russell Ward

“Update 7/27: After posting my initial review I received a phone call and talked with an agent at On Time Experts. He took the time to listen to my situation and apologized for not receiving the costs up front before the service was performed. I may have tried to remedy the situation myself having known the cost but what's done is done. What did happen is they showed they care about their customers and that speaks volumes. He also offered a solution for any service I need in future which was above and beyond. Therefore I bumped my review to 5 stars. Previous Review: Although our service technician was really great which is why I gave it 4 stars we were floored when told the cost to clear our shower drain which happened after the service was performed. I guess it was partially my fault for not asking for the costs up front. And after the service was done what can you do? Make sure you understand the cost before your service is performed.”

Joe Levine

“On Time Experts is my go to place for AC work. Their prices are very fair and the work is top notch. Today my tech, Mark Stocknicki, did a semi annual check up and cleaning of my system and did a very thorough job. He patiently addressed any questions I had. If you need AC work who do you call? - On Time Experts! Also, if you are a veteran or first responder they have a special program for you.”

Tim King

“My tech Tyree was AWESOME & a lifesaver! He got to us as soon as possible and took care of the issue with our central AC. He fixed it and got it running cold in under an hour. I would highly recommend On Time Experts to anyone and everyone who may need their HVAC system maintained or repaired. Five stars all the way!”

Rosalinda Venegas (Rosie)

“Outstanding service! Joey fixed my air conditioning issue with ease. I am very inquisitive and all of the questions I asked were answered professionally. The Joey arrived right on time, wore shoe covers inside the house, and was extremely polite and thorough. Instead of trying to upsell me on a costly replacement, Joey Hiott and Jeff Sterzer diagnosed the exact problem, explained the repair/ replacement clearly, and had issues resolved with a new unit the next day. Excellent, professional and caring work. I will definitely use them again and highly recommend them to anyone needing reliable AC service with One Time Experts. I’m adding those that tirelessly worked on my AC unit all day without attitude or negative demeanor. Always with a smile, great customer service. One Time Experts Alfredo V., Rito A. and Angel, you guys ROCK!!!!”

Cristal Goussen

“Excellent service. The AC technician was very thorough and took the time to check everything carefully instead of rushing through the service. He checked the system performance, temperatures, refrigerant pressures, and other important readings, and also sent me pictures of the measurements so I could see exactly what he found. I really appreciated the transparency, detailed explanation, and professional service. Highly recommended.”

Brinder Bhullar

“The people at OTE were great. Evan and Joey completed a thorough assessment, step by step with photos. I don’t know how they could have been better. Add-on to original review: Had Evan and Joey out to look at my other unit as planned (part of the membership!) and they quickly validated my concerns and went to work diagnosing the system- not looking for a part to sell me- actually from the rootie to the tootie to identify what was causing the issue. These guys are so thorough and professional that it inspires confidence in the experience. I was so happy with these two I introduced them to one of neighbors passing by! You cannot help but love these guys for the dedicated effort. Thanks you two!”

JCG Texas

“Kevin came out to check for a possible leak. He was very thorough and explained everything he was doing and looking for to me. Very polite and friendly. I would definitely contact On Time Experts for any future plumbing repairs.”

mlkaminski

“Otto and George were very respectful, personable and informative of what needed to be done. They were very thorough in diagnosing my A/C issue and provided options to fix the issue. I was previously told by a prior technician from another company that I needed a full A/C replacement unit snd that he would charge $9,400. Called On-Time Experts and they were able to repair the unit for $3k. Highly recommend this company - you even get extra perks by becoming one of their members. Very satisfied first-time customers!!”
