Zach professional. He was friendly; he acted as though he didn’t want to be anywhere else but cleaning and maintaining my HVAC unit. Keep up the good work!

Update: November 28, 2023 Omar arrived on time and proceeded to check out the gas heater/ furnace unit. All is good. Omar checked out our outside A/C unit this past summer - in the middle of the Texas heat wave in late August. He recommended that we probably need to change or replace our 16 year old unit. We got a quote from his company in early September but at that time, the company was in the middle of being sold. Our quote got sidelined. We will revisit the HVAC system in the next couple of months. Winter in Texas doesn’t last that long. It will be warm again in 12 weeks! Another update: May 2023 Our variable blower motor went out so Zinsmeyer came out to replace it. Eric, who was the tech sent to diagnose and replace the blower motor was wonderful and efficiently checked out the entire system. He had the house cooling down on a warm and humid day pretty quickly. Also, he checked the outside unit to make sure everything was working as they should. When he was satisfied, he asked if there were any questions and of course, none because he covered his bases well. Mission accomplished! One thing though. You might want to ask your techs to wear protective cover on their shoes when working inside the house. I had to clean a lot of dirt where the tech walked and worked. He was in and out of the house several times so there was a lot of gritty dirt. Other than that small issue, everything went great. Update: Jose Villareal was the technician that showed up today. I was very impressed because he took his time to do the work that he was suppose to do. He cleaned both filters, and cleaned the outside unit to the point where he got wet! He talked to me about the progress of the work he was doing. He took a longer time than any of the other techs but now I know why. I'd rather have somebody as thorough as Jose than somebody who shows up and gets things done in 25 minutes. Thank you, Jose! Keep up the good work! Technician arrived as scheduled. The business office apparently tried to call beforehand but they were using a disconnected phone number. Luckily, the tech showed up anyway. I updated the phone number so they can reach me next time. As far as the maintenance service goes, he serviced the outside unit first and then came inside the house. The tech was quick and efficient. This company shares the same last name as the one that installed the unit 12 years ago. That brother that installed the unit reportedly sold his company to his other brother hence the same last name. No matter, I’m satisfied with the service. I signed a membership agreement with them and according to the tech, we can call them anytime and they will be here to resolve any problem related to the HVAC unit.
