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.

Sometimes it is better to judge a company by how it responds to a problem than judging it by the problem alone. As such I am retracting my review below. I was contacted by On Time Experts after my review. The gentlemen who called me was professional and willing to do what ever it took to make up for the problem I had. He listened to my complaints and made no excuses. He thanked me for my input and told me changes would be made. He made some concessions and promises which I believe he will keep. The entire incident was handled professionally and well. So, I'm still a customer.

This was my first and last encounter with OnTime Experts. They purchased the company from whom I purchased my AC last summer. (Dring Heating and AC) A great company. I had an appointment for service today. I was told the technician would be at my home between 12 and 4 pm. At 4:15, no technician l, no phone call. I called OnTime. I was told my technician was busy, and it would be another 30 or 35 minutes. Or I could reschedule. The customer service individual was rude and not interested in helping. I told her to cancel the appointment, and she hung up on me. Needless to say, I will be looking for a new AC company. OnTime needs to realize they are not more important than their customers. We have the money.

The OnTime Experts was referred by the home improvement show Texas Home Improvement. The tech was originally going to come out and service my AC and ensure it was ready for the summer heat. Dominic, the tech, kept me up to date with his progress with videos and pictures. Explained all the steps he was doing and how the tests were coming out. He discovered a small gas leak, which I'm grateful for. Small gas leak that could spark into a fire.
After Dominic was done with the inside, he proceeded to take apart, inspect, and test all the outside components on the condenser. He blew the leaves off, cleaned the coils, and tested the current. Then he cleaned up everything. Made me feel at ease with the open communication.
I would recommend The On Time Experts to all my family and friends.

I'm happy with the service but the time waiting is what I find unacceptable. We were told someone would be here between 9am and 1pm. At 2pm, someone finally arrives. It is 6pm and our technician, George, is still here. He found repairs that our unit needed so I understand the extra time. I had to finally cancel our Sunday afternoon plans. I explained my concerns with George and he was unaware how long we had been waiting. It seems there needs to be better communication between the dispatcher and the technician. For a business named On Time Experts, they should concentrate more on their name. Perhaps more technicians in the field or schedule less appointments in the day. Regarding George, we are very impressed with his HVAC knowledge, he was personable and he took the time to explain to us how our unit worked, the repairs it needed and the cost. Thank you George.

I had an excellent experience with on time experts. Kirstie, the coordinator, was incredibly kind and helpful throughout the entire process. Everything was handled so smoothly and professionally. I will absolutely use their services again if needed in the future, and I wont hesitate to refer them to friends and family!

Marco was very communicative and let us know of any findings. We had called for a tune up special I saw on NBC5 channel. He found some leaking gas leading up in lines to our units. Was able to make repair and continue with tune up. I would hire him again to come into my home for work. Could tell he valued his job and company. Thanks!

We had such a good experience with George today. The high in Dallas today was 33, and I realized my thermostat was not getting any power. He came out same day, put in a new disconnect box and transformer. Heat is back up and running once I get a new Ecobee (power surge blew it out). He was courteous, polite and very helpful.

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!

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.

Audi came to my house even when I did not reply to the message (fell asleep). He was friendly, respectful, and knowledgeable. I will likely need to replace cast iron piping, and he was extremely helpful and knowledgable about that, too. He is a good man and deserves a raise! Send him next time, too!

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!

Our repairman, Gilbert, was courteous, knowledgeable, and professional. He explained what he was going to examine. Then, he went down the tasks lists and kept us informed. When his evaluation was complete, he discussed the results, made suggestions according to his company guidelines, and asked if we had any questions or concerns. Gilbert was efficient and did a thorough review. I would recommend his company to my friends and family.

Lance did a great and very professional job, he explained everything he was doing and helped me understand to a high degree what's going on with my air conditioning, and I know it will save me money in the long run. Great service and impeccable work ethic. Definitely will continue to stand by this company. Services:HVAC system maintenance, A/C system maintenance

They arrived quickly and did everything possible to resolve the HVAC issue immediately. Gabe was both pleasant and professional. This is an update to my original review: What started out as a reasonably straight forward repair turned into a repair nightmare. Apparently the replacement motor that was installed was defective and burned up a number of components all through the system.
It took 4 days and countless hours of labor by George, Fabian, and Gilbert but they got everything back in order and running perfectly. I cannot express my gratitude enough for their dedication and dealing with a cranky (overheated) old man to boot. My 5 star rating still holds. Thanks!

My father in laws AC unit went out and I just want to say this company went above and beyond. Joey the tech was very professional, knowledgeable and kind. Joey stepped up and made sure to get my elderly father in law a portable unit so he wouldn't be uncomfortable. I was very pleased with how much it meant to him to make sure my father I'm law was taken care of it really touched my heart. I would recommend On Time Expert to anyone. Thanks Joey!

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.

Joey was phenomenal. We had called one company earlier in the week that had 2 men come out. No help. The next company no-showed when they were supposed to be here on a Saturday morning and called to apologize at the end of the day. I called On Time around 4:30 on a Saturday and Joey was there around 6 pm. He spent an hour and a half in our oppressively hot attic and completely resolved our multiple issues. Joey was pleasant, nice, honest, professional, and courteous. We could not be happier. Thank you.

Our AC capacitor stopped working in the middle of TX summer, and so we called On Time Experts to come out to take a look at it. They showed up by the next day, and Jerad was able to take care of the problem super quickly! He was very informative and explained everything in detail, and was also very friendly and knowledgable. Definitely recommend them as your first call when you're in need!

Collin did a great job trying to fix our a/c outside unit. Unfortunately it was beyond saving (18 years old and in bad shape.). The good news was the cost of repairs was applied to the new system I had installed the next day. The dispatcher, Holly, kept me informed of where the crew was and when they would arrive. I'm really pleased with everything the On-Time Experts did for our home!

Such a great quality from the technicians! The main technician was professional, knowledgeable, and thorough. Was a great teacher to his apprentice as well as to me on the the inspection of my ac units, the current conditions, and preventive maintenance. They both were very respectful and helpful. I would recommend them to anyone of my friends or family! Thanks guys!

Collin came out to the rescue, very knowledgeable and straightforward. Unfortunately, we had to get a entire new AC unit.! He got the process started and made us feel at ease. Great company and great workers. I would recommend On-Time to anyone! Workers came the next day to install the new unit and were on time like they said they would! New unit install and everything looks great and professionalism was fantastic. You guys are the best!

Had a great experience with On Time Experts! Jerad Lawson was such a huge help and took the time to explain the issues with my system instead of just handing me a bill at the end. He even offered to help out with anything else I needed around the house. Great company that hires great people.

I had a drain line clog in my washer line. Alex R. Came out. Got to my house in less than an hour. He was super professional. Explained everything along the way, best plumbing experience I've had by far, no comparison. Once he got that taken care of, he took a look at my water hose line that had busted and recommended replacement options for that as well. Will definitely be going forward with Alex and the on-time experts from now on for all of my plumbing needs.

Audi & Austin were very friendly, knowledgeable & hard working. They did an excellent job. On Time Experts arrives when they say they will, and they check with you before doing any work so that you know the job to be done & the cost beforehand. I highly recommend On Time Experts for any heat, ac, or plumbing issues. Service:Drain cleaning

I would like to thank Holly for the quick response and getting us a tech within hours! Anthony arrived and checked out our system and determined what needed to be done. He was very informative and explained in detail what was wrong and what he did. I signed up for their membership plan which was an awesome blessing! I totally recommend them! Thank you so much Holly and Anthony for your quick response and professional experience and advice!

Our family has used On Time Experts for air conditioning, heating and plumbing repairs at our home. They also installed a new HVAC system in our home. I've found them to be very professional and always on time and they guarantee their work too! It's nice to have this company here in North Texas. All my neighbors are starting to use them too.
