Our tried and True plumbing service provider stopped, providing HVAC services, so we needed to find a new company to check and service our air-conditioning unit and heater. Today, we had our first visit with Terrell, and we could not be happier with the service we received and the thorough and detailed explanation of the company, it’s policies, and the services they provide. We received an excellent update on the condition of our Air conditioner, and are very happy to be with a company that is highly recommended by Angie.

One Hour Team came in yesterday and boy, did just 2 of them tackle those 2 monstrous pieces of equipment to move one from our attic, the other from our side yard in the high heat of the day! They began w laying down tarps in our home to protect the floors from potential dirt and damage. They worked 12 hours straight to replace our units. I can’t imagine how 2 young men were so extraordinary qualified to do such a major job with such expertise. Now our AC is so much more efficient that we can set it on a much higher temperature to be perfectly comfortable. I imagine we will save a lot of money on our future usage. We are beyond thrilled!
