When we responded to a TV ad special for $99 to clean and service our AC unit we expected the usual bait and switch or upsell of unnecessary repairs. We were completely wrong and very impressed with this company. They did a very thorough and excellent job. We ended up signing up for the service contract at $19.a month and it has been the best investment for our home. They have came out three times since then and Star Wars our air conditioner, checked our plumbing, and their employees are very knowledgeable and friendly. I highly recommend these people.

MJ showed up on a Sunday night at 10pm to fix my unit that was completely shut down. I signed up for the maintenance program which saved me some money on the repair and he even found me a coupon on the website. Cant say enough about how thoroughly he explained everything to me. Unit is already cooling down, so thankful. Highly recommend.

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.

We had an amazing experience with On Time Experts from being recognized as a military veteran across the board to the true professionalism, attention to detail, and explaining at every step. No price gauging or forced services or products. Just exactly what was needed for our home. Thanks to George, Cody and Logan for the super in home support. George even checked my warranty first to help me save money. Also, thanks to Andrea and Lexy for the amazing customer service support. I'll be spreading the word about this crew.

We have had wonderful service from On Time Experts. David came out to follow up and inspect our new HVAC system and was so thorough, professional and patient with all of our questions. He made great suggestions to help us work out issues with our air flow (home construction issue, not OTE service) and came back today to install a new vent. He was so personable and did an amazing job!

Dominic was the technician that came out. Was very professional and knowledgeable. This was the first time we have used On Time Experts and after our service today they will be who we call for any future HVAC issue's. I did ask Dominic if we could request him in the future. We are very happy we can. We give Dominic a 10 +

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!

We would like to thank both Diara and Dominic, two techincians, who serviced our home. Thank you for the excellent service. As a representative of On-Time Experts, we appreciate their assistance and guidance provided during the maintenance service. Both technicians were very kind and courteous, knowledgeable and understood our concerns, especially when discussing the efficiency of our HVAC unit. Both addressed the routine maintenance for efficiency of the unit as well as a current EPA change which affects the use of refrigerants in HVAC units. Both young men demonstrated that they were both diligent and dedicated technicians to the trade and craft. Thanks again for the excellent service!

I have so many good things to say about the assistance I received. Kirstie helped me schedule my appt, throughly walked me thru every step of the maintenance plan I signed up for. Was very sweet and helpful the entire time. She kept me informed of my appt and my tech arrival. Once Kyle arrived he was very respectful, and explained everything perfectly. He was very respectful of my home even when he had to get muddy. I will definitely recommend this company in the future.

The service technician, Marco, arrived on time and thoroughly inspected and cleaned both my units, the inside unit and outside unit, including the furnaces. Our prior company did not clean as thoroughly.
Marco was courteous and did something I havent seen before: he cleaned up after himself even vacuuming the floor where a little insulation from the attic had fallen.
Marco pointed out two things that he recommended we keep an eye on and recommended we correct. He took apart the systems and cleaned everything, including the internal blower fan that was pretty dirty.
I would recommend the On Time Experts without hesitation as the value is truly there along with the technical expertise.

Our tech Dominic was a lifesaver. Extremely professional and took the time to explain what he was doing and educate me on the maintenance of our system. Out of the 4 or 5 companies I called over the course of 3 days, On Time was the only one that would arrive within hours of me reaching out for our emergency. I only wish I had called them first. 100% recommend.

Evan and George did a thorough cleaning and inspection of my furnace and ac. They were professional and communicated service needs to me in a way I could understand. Overall they went above and beyond to please me as a first time customer. I appreciate their care for my home throughout their service.

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.

I love this company. When the AC goes south it's great to know that they are there 'same day' when you need them! I've been using them for several years now...for heating,, AC and plumbing and I recommend them highly. Lately I've been really appreciating the communication I get from them prior to the techs arriving at my house. It's really helpful because I'm always updated on their arrival time. I also appreciate the fact that they are there for the consumer on nights and weekends. Several times they've 'saved the day' on a holiday weekend. Today Joseph and Sean did a great job of servicing my HVAC unit and getting it to 100% efficiency for the hot summer weather. All in all an awesome company that is built on integrity and top notch customer service.

Let me first state that my electric bills have become outrageous in the last couple of years. And my system hadn't been cleaned in 10 years. Professional, punctual and helpful describes the young techs that cleaned and analyzed my systems. They identified issues with carbon monoxide production which I didn't know was happening. My AC system was old enough to no longer receive Freon servicing without costing me a lot of money and was using extra electricity.
This answers my first statement. Bottom line, I had a new system installed the next day. Service was incredibly awesome. I'm glad I finally made the decision to have my system cleaned. This company explained everything in detail and I never felt pressured to purchased anything. They are now my go to company!

On Time offered same day service and excellent recognition of Veterans. I selected them for a plumbing problem and received service that afternoon. Charles arrived on time and quickly diagnosed and corrected our problem. He was courteous and in addition to fixing our issue, took the time to answer my questions. I highly recommend their service!

I just had an awesome service call! Justin is very knowledgeable and he was empathetic to my concerns and the issue with my A/C unit. Justin quickly identified the reason why my unit was not producing cool air. He explained the issue, showed me pictures and went over what is required to fix my ac unit. I'm so glad I called this company today and thankful that I signed up for their membership package. I can tell that Justin is passionate about his career and work.

On Time experts showed up within a couple of hours of my call, analyzed the problem and resolved a major issue in a reasonable amount of time. Although they could not resolve the problem immediately, they stayed on it and communicated with me often, keeping me informed. Clint was the technician who came out and resolved my issue. He was competent, friendly and very professional. I would recommend him and his company to anyone.

Justin was on time and detailed with all his work from looking at the cause of issue and explaining how to resolve each. He had to order additional part and was punctual on his appt time and installed efficiently. Would recommend On Time Experts as a business and definitely ask for Justin to service your home.

Collin was absolutely the most knowledgeable HVAC technician I have ever met. He was very transparent, through and he did an excellent job documenting my issues, problems and options. He explained everything using terminology I could understand. On Time experts came within hours of my call on a Monday. Every employee from On Time I interacted with was professional and knowledgeable.

Katie is an absolute rockstar! Our AC went out late on a Sunday night with these crazy high temps. They dispatched Collin out who was so knowledgeable and explained everything thoroughly! Within 2 hours we had a game plan to be up and running with a new unit. Katie is so compassionate and attentive to our needs and situation. She answers day and night and is always so sweet! A true gem! Customers for life- the customer service is unmatched!

My air conditioning went out this morning, so I called my home warranty company and they said it would be 3 - 4 days before they could come. I remembered On Time Experts add and called them. They sent a tech in 45 mins. He was extremely knowledgeable, friendly and patient. He explained how everything works and what we needed. I highly recommend and wouldn't call anyone else. I signed up for their membership too that has great benefits!

AC went out late on a Saturday night with 100 degree heat and I received a prompt call Sunday AM to schedule a visit and had a visit and a diagnostic provided by that morning. My options were explained by Eric in a way I could understand as a new homeowner. Repairs were completed by Monday based on part availability. Price was reasonable and the same as what was discussed initially with no hidden fees. Thank you Chase and Eric for your help! I will be using this company again for other work around the home.
