Mason and Chantz we're excellent installers. They worked in unbelievable extreme heat in our attic putting in a new system only to have to come back because of a system defect that defeated a valve. All is working great and we had to adopt the "boys" in order to have them come back on a day off to cool off in the Brazos.

This company is the best. We have been working with them for over 12 years and have never had an issue. We just had a new heat pump installed Friday before Christmas. It was cold rainy and miserable outside but Esteban & Mason showed up around 8:30 and worked continuously until 4:15 out in the miserable weather. They never even took a lunch break. I offered them drinks and food and they would not stop long enough to even accept them. Both were extremely courteous and professional walking through all the features of the new system. Could not have done anything better. Great guys and great company.

I called to have someone come over and install a new thermostat and take out the electronic one we've been fighting with for years. Wesley came over and I showed him the one we had purchased. After checking the system and after we discussed everything we realized that the one I had purchased wouldn't work because my system had a heat pump and the thermostat that was purchased wouldn't work correctly.
Thank goodness Wes had one that was correct and after checking that all the different colored cords were connected correctly he tested everything out. It is so much easier to use than the one that was replaced and my husband and I both think the air conditioner and heat is working correctly. The original thermostat was never installed correctly to begin with. Thank you Wes for doing such a great job. You were a gentleman and very professional. Thank you again.
