I made a service call late at night and the service tech Dominque arrived promptly and was knowledgeable. He stayed late into the night and early into the morning without complaint. He made the process very smooth and left no question about the service I was being provided. I couldnt have been more happy with the service and I highly recommend this company.

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!!!

Dillon & Trae were the best. They immediately assed the problem and talked me through the repair. Gave me options and we agreed on the plan. They also were done within the time they quoted. Both respectful of my home and nice to our furbabies. On Time Experts is my go to company time and time again.

We were thinking the appointment will be canceled due to the bad weather that day but it didnt. Ross came out here on time and fixed the heating system on the day that was very cold. We greatly appreciated the excellent service and professionalism!!

Kirstie was so nice to speak with on the phone. Great communication.
Seems to go above and beyond for her customers.
Was worried about bursting pipes during a freeze and she talked to me through everything.

George and Richard (on his first day even!) did a great job for me. I had a unique request and they handled and got everything squared away. The whole process was so easy. We've been OnTime customers for a long time and game no regrets!

Great experience, called in the morning about my heater not working and Joey was here in about an hour. Joey was friendly and knowledgeable, he gave me information about my heater that I didnt know. He diagnosed my problem and recommended an electrician, all within an hour. Very pleased with everything, thank you On Time

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.

Angel and George showed up when they said they would and gave wonderful and thorough service. They even had to run to Home Depot but they made sure I had heat before they were done. They worked with us and got it fixed for now. We 100% be going with them for the replacement we will need befor next season!!

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!

KP was exceptional when performing my maintenance checkup. He was methodical and thorough in his approach. I know that my HVAC units are healthier today because of the time and care that he took with my units.

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.

My technician Dominic was awesome! 5 stars. Very friendly and explained everything about my system. He showed me photos of the issues with my system that I will take care of in the future. He also let me know about their plumbing services.

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.

David was very polite and gave me great directions for our operating system. We were due an update on thermostat which was not completed at installation, saw error and made necessary change. Great customer service!

We had a great experience with the technician coming in and diagnosing the problem with our water heater, she was quick and efficient. Only thing I would caution others on is the pricing, the quote to replace our water heater was DOUBLE from several other companies in the area. We ended up not going with this company- so just beware of pricing and get multiple quotes

I needed the bearings in my condenser fan motor replaced. I called On Time experts, Made an appointment and they showed up, as you would expect, on time! The techs were pleasant enough and very quick with the repair.
I think $1100 for that situation is a bit steep. Also, when they left, I went out and took a look. I noticed wires zip tied to the housing. I can tell you that it was never like that. I dont know if I will continue using this company. I did sign up for the preferred customer program. However, Im not sure how I will proceed. Not sure how I feel..
